Success for All (SFA®) is a whole-school reform model (that is, a model that integrates curriculum, school culture, family, and community supports) for students in prekindergarten through grade 8. SFA® includes a literacy program, quarterly assessments of student learning, a social-emotional development program, computer-assisted tutoring tools, family support teams for students’ parents, a facilitator who works with school personnel, and extensive training for all intervention teachers. The literacy program emphasizes phonics for beginning readers and comprehension for all students. Teachers provide reading instruction to students grouped by reading ability for 90 minutes a day, 5 days a week. In addition, certified teachers or paraprofessionals provide daily tutoring to students who have difficulty reading at the same level as their classmates.

Reading Recovery® is an intervention that provides one-on-one tutoring to students in grade 1 with low literacy achievement. This supplemental program aims to improve student reading and writing skills by providing one-on-one tutoring, tailoring the content of each lesson to each student based on observations and analyses of the student strengths and weaknesses from prior lessons. Trained Reading Recovery® teachers deliver tutoring daily in 30-minute one-on-one sessions over the course of 12 to 20 weeks. Reading Recovery® teachers incorporate instruction in topics such as phonemic awareness, phonics, vocabulary, fluency, comprehension, writing, oral language, and motivation depending on student needs.

Dual language programs are long-term instructional programs that provide content and literacy instruction to all students through two languages—English and a partner language—with the goals of promoting academic achievement, bilingualism and biliteracy, and sociocultural competence. Dual language programs can be implemented with students from one language group (in one-way programs) or with students from two language groups (in two-way programs).

The Pathway to Academic Success Project trains teachers to improve the reading and writing abilities of English learners who have an intermediate level of English proficiency by incorporating cognitive strategies into reading and writing instruction. The cognitive strategies include goal setting, tapping prior knowledge, asking questions, making predictions, articulating and revising understanding of text, and evaluating writing.

Word Generation is a supplemental program that aims to improve students’ reading comprehension by building students’ vocabulary, academic language, and perspective-taking skills through classroom discussion and debate. Word Generation was developed for all students; however, English learners in particular could benefit from its focus on academic language. Word Generation consists of a series of interdisciplinary units with daily lessons focused on a high-interest issue to increase student engagement. Each unit targets a small number of academic vocabulary words that are integrated into texts, activities, writing tasks, debates, and discussions across content areas. Several Word Generation programs exist. In the Word Generation Weekly (WordGen Weekly) and Word Generation Elementary (WordGen Elementary) programs, units are intended to be used across English language arts, math, science, and social studies in grades 6–8 and grades 4 and 5, respectively. In the Science Generation (SciGen) and Social Studies Generation (SoGen) programs, units can supplement or be used in place of regular science and social studies curriculum units in grades 6–8. The different Word Generation programs can be implemented separately or together.

District leaders in a large urban school district in central Florida wanted to examine the efficacy of a new curriculum designed to enhance the word knowledge of grade 5 students so as to improve reading achievement. The new curriculum, called Word Knowledge Instruction (WKI), consists of 15-minute lessons 4 days a week for 20 weeks. The lessons address state standards and cover 20 prefixes and suffixes. Thirty-nine schools participated in the study, with 92 English language arts (ELA) teachers in high-poverty schools randomly assigned within schools either to use WKI or to continue to use their standard ELA curriculum. Classroom observations revealed that WKI was implemented as intended. WKI had a positive effect, equivalent to an increase of 9 percentile points, on students' ability to correctly extract and spell a base word from a derived word, one of the skills explicitly taught by WKI. WKI had no effect on two other related reading skills that were not directly taught by WKI (students' ability to select a nonword that best fits the grammatical context of a sentence or to use knowledge of word parts to infer meaning of new words) or on students' vocabulary or reading scores. These findings suggest that, although students learned what they were explicitly taught, the transferability to related but not directly taught skills might require more intense or longer duration instruction or additional professional development for teachers.

This study evaluated the efficacy of the Word Learning Strategies (WLS) supplementary program to improve elementary students' vocabulary skills and reading comprehension. The study used a multi-site cluster randomized, experimental design, which randomly assigned 92 4th grade classrooms (n=2558 students) from two cohorts to a treatment or control group. Results indicated that the program was positively associated with gains in students' vocabulary learning and knowledge as measured by the Word Learning Strategies Test and the VASE Assessment, and in students' reading comprehension as measured by the Gates-MacGrinitie Reading Test, after accounting for differences in baseline measures. The use of the WLS program also led to increases in teachers' awareness of strategies to support their students' vocabulary and reading comprehension.

The English Language and Literacy Acquisition--Validation (ELLA-V) study was a five-year evaluation of a program that provided professional development, coaching, and curricula that targeted English-as-a-second-language (ESL) instruction for teachers of K-3 English learners (ELs). ELLA-V was implemented in 10 school districts in Texas in the 2013-14 through 2016-17 school years. The project was federally funded by a grant from the U.S. Department of Education's Investing in Innovation (i3) Fund (PR/Award Number U411B120047). Professors at Texas A&M University were the recipients of the grant and developed the professional development, the coaching program, and the curricula. Researchers at the Center for Research and Reform in Education (CRRE) at Johns Hopkins University were contracted to conduct the independent evaluation. The evaluation of ELLA-V was a multi-site cluster randomized trial designed to meet the What Works Clearinghouse (WWC) standards for rigorous education research (WWC, 2017). The study used a mixed method design to estimate program impacts on student and teacher outcomes and document the fidelity of implementation and perceived quality of the program.

Supporting the reading comprehension and content knowledge acquisition of English language learners (ELs) requires instructional practices that continue beyond developing the foundational skills of reading. In particular, the challenges ELs face highlight the importance of teaching reading comprehension practices in the middle grades through content acquisition. We conducted a randomized control trial to examine the efficacy of a content acquisition and reading comprehension intervention implemented in eighth-grade social studies classrooms with English language learners. Using a within-teacher design, in which 18 eighth-grade teachers' social studies classes were randomly assigned to treatment or comparison conditions. Teachers taught the same instructional content to treatment and comparison classes, but the treatment classes used instructional practices that included comprehension canopy, essential words, knowledge acquisition, and team-based learning. Students in the treatment group (n = 845) outperformed students in the comparison group (n = 784) on measures of content knowledge acquisition and content reading comprehension but not general reading comprehension. Both ELs and non-ELs who received the treatment outperformed those assigned to the BAU comparison condition on measures of content knowledge acquisition (ES = 0.40) and content-related reading comprehension (ES = 0.20). In addition, the proportion of English language learners in classes moderated outcomes for content knowledge acquisition.

Using a randomized control trial, we evaluated the impact of a year-long professional learning (PL) program for teachers designed to support their multilingual learners' language and literacy skills. The PL included evidence-based instructional practices for literacy, a semi-structured model for collaboration, and a strengths-based approach in instruction. Participants included 39 kindergarten and first-grade teachers and 106 multilingual learners (MLs) from 13 schools in two districts in the Southeastern United States. Using a mixed modeling approach, we found significantly higher literacy growth on the Measures of Academic Progress (MAP) for MLs whose teachers participated in the PL. The PL also had a significant impact on teachers' collaboration planning and processes with their students' English as a Second Language (ESL) teachers. Effect sizes for the impact on teachers' use of evidence-based instructional strategies and collaboration frequency were large but not statistically significant. The findings from this study show positive impacts of a teacher professional learning program on teachers' practices and young MLs' literacy growth.

The purpose of this cluster randomized group study was to investigate the effect of multitiered, dual-language instruction on children's oral language skills, including vocabulary, narrative retell, receptive and expressive language, and listening comprehension. The participants were 3- to 5-year-old children (n = 81) who were learning English and whose home language was Spanish. Across the school year, classroom teachers in the treatment group delivered large-group lessons in English to the whole class twice per week. For a Tier 2 intervention, the teachers delivered small-group lessons 4 days a week, alternating the language of intervention daily (first Spanish, then English). Group posttest differences were statistically significant, with moderate to large effect sizes favoring the treatment group on all the English proximal measures and on three of the four Spanish proximal measures. Treatment group advantages were observed on Spanish and English norm-referenced standardized measures of language (except vocabulary) and a distal measure of language comprehension.

Given the growing number of Latino English learners and the lack of evidence-based educational opportunities they are provided, we investigated the impact of one potentially effective literacy intervention that targets struggling first-grade Spanish-speaking students: Descubriendo La Lectura (DLL). DLL provides first-grade Spanish-speaking students one-on-one literacy instruction in their native language and is implemented at an individualized pace for approximately 12 to 20 weeks by trained bilingual teachers. Using a multisite, multicohort, student-level randomized controlled trial, we examined the impact of DLL on both Spanish and English literacy skills. In this article, we report findings from the first of three cohorts of students to participate in the study. Analyses of outcomes indicate that treated students outperformed control students on all 11 Spanish literacy assessments with statistically significant effect sizes ranging from 0.34 to 1.06. Analyses of outcomes on four English literacy assessments yielded positive effect sizes, though none were statistically significant. [This article was published in "AERA Open" (EJ1229779).]

Reading and comprehending content area texts is important for academic and professional success as well as life skills necessary to maintain good health and quality lifestyle. Spanish speaking English language learners have shown poor performance on high-stakes assessments in reading comprehension. The number of Spanish speaking English learners (ELs) in our schools continues to increase at a fast pace, and therefore it is imperative that we address their reading comprehension needs swiftly and effectively. The text structure strategy has shown positive results on comprehension outcomes in many research studies with students at Grades 2, 4, 5, and 7. This study is the first implementation of instruction about the text structure strategy expressly designed to accommodate the linguistic and comprehension needs of Spanish speaking ELs in Grades 4 and 5. Strategy instruction on the web for English learners (SWELL) was designed to deliver instruction about the text structure strategy to Spanish speaker English learners. A randomized controlled study with pre and post-tests was conducted with 14 classrooms at fourth-grade and 17 classrooms at fifth-grade in high poverty schools where over 85% of students were Spanish speaking bilinguals or ELs. Analysis of data using multi-level models show moderate to large-effects favoring the students in the SWELL classrooms over the business as usual control classrooms on important measures such as a standardized reading comprehension test and main idea and cloze tasks. This research has practical implications for the use of web-based tools to provide high-quality and supportive instruction to improve Spanish speaking ELs reading comprehension skills.

Purpose: This study aimed to examine the effect of an intensive vocabulary intervention embedded in e-books on the vocabulary skills of young Spanish-English speaking English learners (ELs) from low-socioeconomic status backgrounds. Method: Children (N = 288) in kindergarten and 1st grade were randomly assigned to treatment and read-only conditions. All children received e-book readings approximately 3 times a week for 10-20 weeks using the same books. Children in the treatment condition received e-books supplemented with vocabulary instruction that included scaffolding through explanations in Spanish, repetition in English, checks for understanding, and highlighted morphology. Results: There was a main effect of the intervention on expressive labeling (g = 0.38) and vocabulary on the Peabody Picture Vocabulary Test--Fourth Edition (g = 0.14; Dunn & Dunn, 2007), with no significant moderation effect of initial Peabody Picture Vocabulary Test score. There was no significant difference between conditions on children's expressive definitions. Conclusion: Findings substantiate the effectiveness of computer-implemented embedded vocabulary intervention for increasing ELs' vocabulary knowledge.

This study reports 2 years of findings from a randomized controlled trial designed to replicate and demonstrate the efficacy of an existing, successful professional development program, the Pathway Project, that uses a cognitive strategies approach to text-based analytical writing. Building on an earlier randomized field trial in a large, urban, low socioeconomic status (SES) district in which 98% of the students were Latino and 88% were mainstreamed English learners (ELs) at the intermediate level of fluency, the project aimed to help secondary school students, specifically Latinos and mainstreamed ELs, in another large, urban, low-SES district to develop the academic writing skills called for in the rigorous Common Core State Standards for English Language Arts. The Pathway Project draws on well-documented instructional frameworks that support approaches that incorporate strategy instruction to enhance students' academic literacy. Ninety-five teachers in 16 secondary schools were stratified by school and grade and then randomly assigned to the Pathway or control group. Pathway teachers participated in 46 hr of training to help students write analytical essays. Difference-in-differences and regression analyses revealed significant effects on student writing outcomes in both years of the intervention (Year 1, d = 0.48; Year 2, d = 0.60). Additionally, Pathway students had higher odds than control students of passing the California High School Exit Exam in both years.

The achievement gaps between poor and more affluent students are persistent and chronic, as many students living in poverty are also members of more isolated communities where dialects such as African American English and Southern Vernacular English are often spoken. Non-mainstream dialect use is associated with weaker literacy achievement. The principal aims of the two experiments described in this paper were to examine whether second through fourth graders, who use home English in contexts where more formal school English is expected, can be taught to dialect shift between home and school English depending on context; and whether this leads to stronger writing and literacy outcomes. The results of two randomized controlled trials with students within classrooms randomly assigned to DAWS (Dialect Awareness, a program to explicitly teach dialect shifting), editing instruction, or a business as usual group revealed (1) that DAWS was more effective in promoting dialect shifting than instruction that did not explicitly contrast home and school English; and (2) that students in both studies who participated in DAWS were significantly more likely to use school English in contexts where it was expected on proximal and distal outcomes including narrative writing, morphosyntactic awareness, and reading comprehension. Implications for theory and practice are discussed.

This study examined benefits of connecting meaning, speech, and print in vocabulary learning for kindergarten English learners. Students screened eligible with limited English proficiency were randomly assigned to two instruction conditions. Both groups received direct instruction in high frequency root words. One condition featured added attention to orthographic and phonological word features. Increased attention to the spoken and printed word forms was associated with significantly greater gains in general vocabulary and word reading, and in taught-word spelling. Results suggest features of effective vocabulary instruction for young and English learner students.

This study examined the initial efficacy of World Generation (WorldGen), a Tier I social studies instructional approach for emergent bilingual (EB) students and their native English-speaking (non-EB) peers in Grades 6 and 7. WorldGen builds on prior research on instructional practices that have been associated with improved content knowledge and literacy outcomes for EBs in classes of students with varying English proficiency. Using a within-teacher design, middle grades world history teachers' classes were randomly assigned to WorldGen treatment (17) or comparison conditions (16) for three to four approximately two-week units. The student sample included 42% EBs. Students in the treatment condition (n = 373) scored higher, on average, on world history content (Hedges' g = 0.47) and vocabulary knowledge (Hedges' g = 0.41) than students in the comparison condition (n = 343) but no statistically significant findings were yielded regarding disciplinary literacy skills at the end of WorldGen instruction. Of primary interest, the statistically significant main effects indicated that world history content knowledge and vocabulary learning was similar for both current EB and non-EB students in the treatment condition. The findings provide initial support for the use of the WorldGen instructional practices for improving content acquisition and vocabulary in general education social studies classes with students with a range of English proficiency. Furthermore, teachers perceived the WorldGen instructional practices and materials as providing the information and learning experiences necessary to support students in meeting grade-level expectations.

This cluster randomized control trial examines the effects of the Science Notebook in a Universal Design for Learning Environment (SNUDLE) on elementary school student science academic achievement and motivation outcomes. Multilevel analyses examined the impact of SNUDLE for all students and important student subgroups. Overall, students who received the SNUDLE intervention had similar motivation and academic achievement in science to their peers who did not receive the SNUDLE intervention. However, relative to students with disabilities in the comparison group, students with disabilities who used SNUDLE scored significantly higher on motivation in science and science academic achievement, with effect sizes (ES) ranging from 0.82 to 1.01. Furthermore, SNUDLE appeared to have a small but statistically significant positive impact on science academic performance among students whose home language is other than English or Spanish with an ES of 0.35. Fidelity of implementation analysis shows sufficient teacher training but fidelity of teacher and student usage of SNUDLE needs to be improved. The qualitative analysis of teacher interviews suggests that teachers perceived benefits of SNUDLE in support language acquisition and science writing skills. Both quantitative and qualitative findings suggest that SNUDLE holds promise for improving academic performance in science and confidence and motivation among some of the most vulnerable student populations.

The purpose of this study was to evaluate the Literacy-Infused Science Using Technology Innovation Opportunity (LISTO) validation project (Valid 45). LISTO was funded by the Investing in Innovation (i3) Fund and involved a multi-year intervention that provided virtual professional development and coaching, and literacy-infused science curricula to fifth-grade science teachers who taught predominantly low-income students and in predominantly rural public schools in Texas. The overarching goal of LISTO is to validate, via a 5-year longitudinal randomized controlled trial (RCT) study, literacy-infused science (LIS) instructional and curricular innovations to increase instructional capacity of teachers and to improve students' science and reading/writing literacy achievement in rural/non-rural schools for economically challenged (EC), inclusive of English language learners (ELL) students. Outcomes collected in the 2017-18 school year were considered to be exploratory, given the timing of Hurricane Harvey, which impacted Texas in August of 2017. Outcomes in the 2018-19 school year served as the confirmatory contrasts. LISTO resulted in increased teacher capacity to implement research-based strategies while teaching science content, yet this improvement did not necessarily translate into improved student achievement in science or reading. The LISTO professional development and coaching covered pedagogical strategies for teaching science, including those that have been shown to improve literacy and be particularly effective for ELs. There was a negative impact on students' science achievement in both 2017-18 (ES = -0.10) and in 2018--19 (ES = -0.13). There was a negative program impact on students' science interest (ES = -0.14), as measured by a survey, in 2017-18, and no impact in 2018-19. These quantitative findings were in conflict with qualitative data collected from LISTO teachers, who indicated that the program led to improvements in both science vocabulary and engagement and self-efficacy in science for students. LISTO had positive effects on teacher practices for a subsample of teachers, specifically on increased delivery of research-based instruction to teach science content as rated on a rubric by external reviewers (ES = +1.12). LISTO appeared to improve instructional practices for a sample of teachers who implemented the program for two years with complete data but did not positively impact student or teacher outcomes more broadly. However, results should be cautiously interpreted due to limitations of delayed and incomplete implementation in the first year of the project due to Hurricane Harvey. Encouragingly, teachers' overall positive reactions to the program suggest its potential to improve student affect and learning, but more extensive implementation experience by teachers and multi-year exposure by students starting from early grades may be needed to yield measurable benefits. Clearly, such focuses emerge as a highly recommended topic for future research.

This study reports findings from a multisite cluster randomized controlled trial designed to validate and scale up an existing successful professional development program that uses a cognitive strategies approach to text-based analytical writing. The Pathway to Academic Success Project worked with partner districts affiliated with 4 National Writing Project (NWP) sites in southern California. Informed by a wide body of research on the efficacy of strategy instruction to enhance students' academic literacy, the intervention aimed to help secondary school students, particularly Latinos and mainstreamed English learners, to develop the academic writing skills called for in the rigorous Common Core State Standards for English Language Arts. Two hundred thirty teachers from partner districts affiliated with the NWP sites were stratified by school and grade and then randomly assigned to the treatment or control group. Treatment teachers participated in 46 hrs of training and learned how to apply cognitive strategies by using an on-demand writing assessment to help students understand, interpret, and write analytical essays about nonfiction texts. Multilevel models revealed significant effects on a holistic measure of an on-demand writing assessment (d = 0.32) as well as on 4 analytic attributes: content (d = 0.31), structure (d = 0.29), fluency (d = 0.27), and conventions (d = 0.32). Four dimensions of scaling up--spread, reform ownership, depth, and sustainability--are also discussed.

Using a randomized controlled trial, we tested a new teacher professional development program for increasing the language and literacy skills of young Latino English learners with 45 teachers and 105 students in 12 elementary schools. School-based teams randomly assigned to the intervention received professional development focused on cultural wealth, high-impact instructional strategies, and a framework for collaboration. We observed each teacher three times during the school year and assessed students individually at the beginning and end of the school year using the Woodcock Muñoz Language Survey (WMLS). Using an intent-to-treat (ITT) analysis, we found effects for the intervention on teachers' implementation of high-impact instructional strategies and students' language and literacy skills.

Although extensive research has shown the educational value of different types of interactive visualizations on students' science learning in general, how such technologies can contribute to English learners' (ELs) understanding of complex scientific concepts has not been sufficiently explored to date. This mixed-methods study investigated how interactive dynamic and static visualizations embedded in web-based inquiry instruction can support ELs and non-ELs in developing a coherent understanding of energy and matter transformations in life science. A total of 331 seventh-grade ELs and non-ELs were randomly assigned to a dynamic or a static visualization condition. During inquiry instruction, students in the dynamic group explored interactive dynamic visualizations of energy and matter transformations; students in the static group explored static, yet otherwise equivalent, interactive visualizations. The results show that, while both forms of visualizations were beneficial for students, dynamic visualizations had significant advantages for improving all students' understanding of the target concepts. Our analyses of video data revealed that ELs and non-ELs in the dynamic condition engaged in more talk turns to interpret the scientific phenomena using both visual and textual representations, whereas ELs and non-ELs in the static condition appeared to rely on textual information to obtain new ideas about the scientific phenomena from the visualization. Compared to the static group, students in the dynamic group also more successfully evaluated and consolidated a range of ideas to develop coherent scientific explanations using evidence from the visualization. This study provides evidence that interactive dynamic visualizations have promise for supporting science learning for all students, including ELs who are often underserved in mainstream science classrooms.

This study examines the effect of 30 min of small group explicit instruction on reading outcomes for first-grade Spanish-speaking English learners (ELs) at risk of reading difficulties. Participants were 78 ELs from seven schools who were receiving Spanish only, or Spanish and English, whole group reading instruction in first grade. Students were rank-ordered within schools and then randomly assigned to a treatment condition (n = 39) or a comparison condition (n = 39). Students in the treatment condition received instruction on transition elements that supported their transfer of skills from Spanish to English. Students in the comparison condition received Business as Usual instruction from a variety of commercially available programs. Findings indicated that ELs in both conditions made significant gains from pretest to posttest on all reading outcomes even though instruction in the treatment condition focused significantly more on higher order skills (i.e., vocabulary, comprehension, and transition elements) whereas instruction in the comparison condition focused significantly more on lower order skills (i.e., phonics, word work, and sentence reading). Implications for practice and future research are discussed.

This study uses a sequential exploratory mixed-methods design to examine the impact of a year-long teacher professional development (PD) program on literacy instruction for multilingual learners classified as English language learners (ELLs) in the United States. Addressing the challenge of scripted curricula that often fail to meet the linguistic needs of ELLs, this study examines how sustained PD and coaching can empower teachers to transform scripted lessons into inclusive, language-rich instruction. The PD consisted of coursework and instructional coaching for some of our treatment teachers, focusing on enhancing teachers' skills in an English language development framework centered on oral language, vocabulary usage, and immersive writing. Participants for this study included eight Grade 2 teachers who were part of the larger cohort of elementary school teachers participating in the PD program (treatment teachers), and four Grade 2 teachers who were not part of the PD training (comparison teachers). Three of the treatment teachers also received instructional coaching. Quantitative results showed that treatment teachers devoted significantly more time to essential literacy components and achieved higher rubric scores in vocabulary and oral language development. Qualitative analysis revealed increased attention to oral language and vocabulary instruction among treatment teachers, who implemented ELL-specific literacy strategies more frequently, consistently, and effectively. These findings suggest that the synergy of systematic coursework and iterative coaching is essential for advancing best practices in linguistically diverse educational contexts worldwide.

This study assesses the long-term linguistic and academic outcomes associated with different bilingual language education models for low-income dual language learners (DLLs) residing in a bilingual, bicultural context. As part of the Miami School Readiness Project (MSRP), we analyzed the impact of program model on gains in English language proficiency and 5th grade standardized achievement in reading and math and grade point average (GPA) for five cohorts of DLLs followed throughout elementary school. Participants had been enrolled in public pre-K programs or received childcare subsidies to attend center- or family-childcare from 2002 to 2007 in Miami-Dade County, Florida (N = 20,870). Controlling for several student-level background variables correlated with educational outcomes, correlational and multiple regression analyses revealed that bilingual, rather than monolingual, forms of instruction were associated with acquiring English faster and superior performance in all measures of 5th grade academic achievement. Importantly, two-way immersion models that support the home language and culture and integrate language majority and minority learners were associated with faster English acquisition, which mediated the link between Two-Way Immersion (TWI) programs and higher GPAs. We discuss the implications of our findings for educational policy and practice and highlight future research directions.

Research shows that Early College high schools have a significant impact on high school and college outcomes for students from low income and racial/ethnic minority backgrounds, but how similar opportunities extend to English learners (ELs) remains unknown. We examine a program that offers Early College opportunities in high schools serving large EL populations in California. Leveraging an exogenous policy change and rich administrative records, we look at the outcomes of pre- and postprogram cohorts of ELs (N = 15,090) in treated and untreated high schools. We find large, significant estimated effects on college credits earned in 12th grade but no effect on immediate college attendance after high school. The probability of attending a 4-year college decreased.

California State University, San Bernardino (CSUSB) and the Riverside County Office of Education (RCOE) were awarded an Investing in Innovation (i3) Development grant in 2015 to investigate the impact of an early education mathematics program on English Learner students at two rural school districts in Riverside, CA. Teaching English Learners Early Mathematics (TEEM) had five major goals: to improve the academic achievement of English Learners (ELs) (Goal 1); to improve teacher knowledge and beliefs for teaching math to ELs (Goal 2); to improve the teaching of math to ELs and all students (Goal 3); to develop principals as instructional leaders in mathematics (Goal 4); and to build a learning partnership that develops, sustains and shares a model of instructional change supporting ELs. (Goal 5). In support of these goals, a combination of four mutually supportive interventions were implemented. The study followed four cohorts of students preK-6th grade over 4 years from 2015-2016 to 2018-2019. The project received a no-cost extension through 2020 but data collection difficulties due to COVID-19 and resulting school shutdowns made it impossible to continue. Data collected included teacher assessments, classroom observations, teacher surveys, student state-level assessments, and student notebook ratings. TEEM Teachers demonstrated growth in mathematics content knowledge, as measured by the Learning Mathematics for Teaching (LMT) Assessment. They showed improved self-efficacy beliefs relative to a comparison group. Participating teachers' mathematics content knowledge improved relative to a comparison group of non-participating teachers in each project year (although due to sample size, the difference was not statistically significant in the last two project years). Student Math and English Language scores on state-wide tests increased each year for students with any exposure to the program, though not to a statistically significant degree.

Two-way dual language (DL) classrooms enroll students of two different language backgrounds and teach curriculum in both languages. I estimate the effect of attending a DL school on student achievement using school choice lotteries from Charlotte-Mecklenburg School District in North Carolina, finding local average treatment effects of 0.04 and 0.05 standard deviations per year in math and reading, respectively. Attending a DL school increased test scores for English learners (ELs) and for non-ELs by a similar magnitude. The positive effects of winning the lottery to attend a DL school are substantially larger than the average effect of assignment to other magnet schools, and several peer and school characteristics are ruled out as explanations for the increased test scores. There is no statistically significant evidence that attending a DL school changed the probability of having EL status throughout elementary school.

In this cluster randomized control trial study, the authors explored the efficacy of an intervention designed to improve second-grade English learners' knowledge of challenging, high-utility English vocabulary. The authors also examined whether the intervention had a differential effect on content words that differ on two attributes (cognate status and abstractness designation) and whether the effects lasted across time. Within schools, teachers were randomly assigned to treatment or control conditions, resulting in 12 treatment classrooms and 10 control classrooms. Teachers in the treatment condition developed vocabulary using six methods: interactive shared reading, direct instruction of individual words, instruction in cognate use, activities to foster word consciousness and reinforce instructed words, and use of visual and linguistic supports. Teachers in the control condition read the same books with the target vocabulary inserted into the stories. Findings on the curriculum-based and standardized measure of vocabulary indicated that the intervention implemented for four 50-minute lessons per week for 18 weeks was effective in helping English learners acquire challenging high-utility school-relevant vocabulary (Cohen's d = 1.88 for content words; d = 0.41 for connecting words; d = 0.47 for the Test of Oral Language Development). The effects differed by word characteristics, with higher effect sizes for words that are noncognates (d = 1.57 for both concrete and abstract noncognates; d = 1.02 concrete cognates; d = 0.81 for abstract cognates). Ten months after the intervention, treatment students still outperformed control students on content vocabulary learned during the intervention (d = 1.31). This study helps validate a multifaceted approach to vocabulary intervention and research.

We examine the promise, usability, and feasibility of an intelligent tutoring system (ITS) to improve the vocabulary and language proficiency in science and social studies of Latinx second grade English learners (ELs). Participants were 217 ELs attending English only programs or bilingual programs. Findings from the clustered randomized control trial using a researcher-developed proximal assessment indicated that students who used the ITS significantly improved their vocabulary knowledge of the words taught compared to students in the comparison group (ES = 0.38). Results also indicated that most students enjoyed using the ITS and learning new words. Teachers found the program feasible and beneficial to their students.

EMPOWER was an Investing in Innovation (i3) development grant awarded to Cabarrus County Schools by the Office of Innovation and Improvement, U.S. Department of Education. EMPOWER provided social-emotional, academic, and non-cognitive supports in magnet school settings to students from low-income families. Family engagement and teacher professional learning on cultural responsiveness were key pillars of the EMPOWER program. A dual-language immersion plus rigor model was implemented at treatment elementary schools while a STEM or IB model was implemented at treatment secondary schools. Literacy skills were assessed for the elementary study using the DIBELS standardized assessment. Math achievement was assessed for the secondary study using standardized statewide math test scores. The impact evaluation used a longitudinal quasi-experimental design (QED) to examine the effect of EMPOWER on literacy skills and math achievement. Hierarchical linear modeling was run to analyze outcomes for EMPOWER students compared to a matched sample of comparison students with similar baseline scores who participated in business-as-usual, traditional academic instruction. Results showed no statistically significant impact on literacy skills or math achievement. [The report was submitted to the Cabarrus County (NC) Schools.]

In this experimental study, 20 multiple-choice test items from the Massachusetts Grade 5 science test were linguistically simplified, and original and simplified test items were administered to 310 English learners (ELs) and 1,580 non-ELs in four Massachusetts school districts. This study tested the hypothesis that specific linguistic features of test items contributed to construct-irrelevant variance in science test scores of ELs. Simplifications targeted specific linguistic features, to identify those features with the largest impacts on ELs' test performance. Of all the linguistic simplifications used in this study, adding visual representations to answer choices had the largest positive effect on ELs' performance. These findings have significant implications for the design of multiple-choice test items that are fair and valid for ELs.

Adolescents with disabilities have great difficulty with academic content in middle school, and their teachers have difficulty teaching them to understand and use academic language. We taught teachers of 6th grade students with Learning Disabilities, over half of whom were also English Language Learners (ELL), to implement about 15 minutes of daily interactive vocabulary instruction in their intact special education English/Language Arts classes. Three schools were assigned randomly to treatment (2 schools) or control conditions (1 school; 52 students total). We developed instructional routines to introduce four new words per week in three 4-week units to test for replicability. ANCOVAs (with each cycle's pretest and intelligence quotient (IQ) as covariates) were conducted on taught vocabulary, all of which favored the treatment condition with effect sizes ranging 0.6 to 0.7 per cycle. Near-transfer effects to vocabulary usage were weaker, with significant effects in the last two cycles. Effects were similar for students with disabilities who were ELL and native English speakers. Treated students maintained their knowledge of words 4 to 24 weeks following the close of treatment. [This article will be published in "Learning Disability Quarterly."]

The purpose of this evaluation was to understand the development, implementation, and impact of Project Exc-EL (Excellence for English Learners), a school-wide intervention focused on providing teacher professional development and training to better support English learners (ELs) in New York. Project Exc-EL focuses on training teachers to use data to identify EL student needs, creating a school climate focused on college and career readiness, and providing school coaches to support teachers as they serve EL students and their families. Project Exc-EL developed and implemented an enhanced, comprehensive design that addressed the unique and urgent needs of low-incidence EL population school districts -- districts that are struggling to provide a comprehensive, rigorous education for the newest members of their communities. The project employed a data-driven, tiered approach to instruction that builds on community partnerships to create personalized, expanded learning opportunities for students. External evaluators conducted an impact and an implementation study to ascertain the outcomes of the project and gauge the fidelity of implementation of the project. The evaluation questions address whether Project Exc-EL increases EL student achievement in math and English Language Arts (ELA), and how the developer implemented the program across four schools. Specifically, the developers implemented the key components related to creating a school culture of college and career readiness, training teachers in data use, and providing school coaches to support teachers. While the developers implemented the project with fidelity, there were no significant differences in math or ELA outcomes of EL students. Given that the focus is on training teachers on data use, building school culture, and providing school coaches for teachers, future research should include intermediate outcomes, or moderators, such as improved teacher instruction and pedagogy, to better understand the mechanisms of student achievement for English learners.

In this study, we use microdata from 12 Florida county-level school districts and a regression discontinuity design to examine the effects of early grade retention on the short-, medium-, and long-term outcomes of English learners. We find that retention in the third-grade substantially improves the English skills of these students, reducing the time to proficiency by half and decreasing the likelihood of taking a remedial English course in middle school by one-third. Grade retention also roughly doubles the likelihood of taking an advanced course in math and science in middle school, and more than triples the likelihood of taking college credit-bearing courses in high school for English learners. We also find that these benefits are larger for foreign born students, students with higher latent human capital in third grade as proxied by their math scores, students whose first language is Spanish, and students in lower-poverty elementary schools.

This article reports on a study that investigated achievement in math of third and fourth grade dual language immersion (DLI) students, building on research that has demonstrated the academic achievement of students who receive content instruction predominantly in the target language. Our study expands the scope and methodology of prior research by including one-way programs in three languages (Chinese, French and Spanish) and two-way Spanish-English programs; and by relying on propensity matching to mitigate possible effects of school and student differences. In our third grade study, we compared students' math scores in relation to their English Language Arts (ELA) achievement to control for pre-existing differences between DLI and non-DLI students. DLI students who attained the same levels in ELA, and who received math instruction in a target language, performed at the same level as their non-DLI peers in third grade math tests given in English. For the fourth grade study, we compared DLI students to a propensity-matched non-DLI group. DLI students grew more in math than their counterparts not in DLI. The results from this natural experiment indicate that students in a DLI program that has been implemented state-wide were able to succeed academically in math.

The purpose of this study was to document the design, classroom implementation, and effectiveness of interactive online units to enhance science learning over 3 years among students with learning disabilities, English learners, and general education students. Results of a randomised controlled trial with 2,303 middle school students and 71 teachers across 13 schools in two states indicated that online units effectively deepened science knowledge across all three student groups. Comparing all treatment and control students on pretest-to-posttest improvement on standards-based content-specific assessments, there were statistically significant mean differences (17% improvement treatment vs. 6% control; p < 0.001); no significant interactions were found between treatment condition and learning disability or English learner status, indicating that these two groups performed similarly to their peers; students with learning disabilities had significantly lower assessment scores overall. Teachers and students were moderately satisfied with the units.

This randomized controlled trial in 55 low-performing schools across Florida compared 2 early literacy interventions--1 using stand-alone materials and 1 using materials embedded in the existing core reading/language arts program. A total of 3,447 students who were below the 30th percentile in vocabulary and reading-related skills participated in the study. Both interventions were implemented with fidelity for 45 minutes daily for 27 weeks in small groups of 4 students (or 5 in grade 2). The standalone intervention significantly improved grade 2 spelling outcomes relative to the embedded intervention; there were some differential impacts due to cohort and baseline and, in kindergarten, to English-learner status. On average, students in schools in both interventions showed similar improvement in reading and language outcomes and similar percentile gains to those in recent systematic reviews. Results are discussed with respect to alignment of Tier 2 instruction with Tier 1 instruction. [This paper was published in "Elementary School Journal" (EJ1171896).]

Vocabulary acquisition is central to language learning, and many instructors believe that technology can facilitate this core activity. While numerous websites and apps offer language-learning activities and games, not all provide evidence that their content and techniques are effective. VocabularySpellingCity (VSC), however, commissioned a study in 2016 to document its effectiveness. Researchers at McREL, a nonprofit education research and development organization, found favorable results among mostly native English-speaking primary school students, including a 43% increase in vocabulary retention scores as measured by pre- and post-tests of 143 students in a southeastern U.S. elementary school (Arens & Mace, 2017). VSC is a website and app that provide users with activities to learn vocabulary, spelling, phonics, and writing. Instructors create study lists by specifying words, definitions, and sample sentences before assigning activities. They can also monitor individual student progress (scores) as well as participation (time spent and number of activities completed). Although designed for K-12 students, VSC is popular among the author's community college colleagues, and the author of this article was interested in learning if findings by McREL hold true for adult ESOL students. Therefore, in fall 2017, Tim Krause conducted a study similar to Arens & Mace (2017) that involved 22 intermediate writing students and 18 academic reading students at Portland Community College in Portland, Oregon. Krause wanted to know if students who chose to use VSC would demonstrate greater improvement in vocabulary retention compared to those who chose other study methods. The results indicate that if community college instructors identify best practices and carefully curate the experience, then the data suggest their adult ESOL students are likely to benefit from using VSC.

The growing number of students whose primary language does not match the language of their schools and a steadily growing performance gap has prompted widespread attention to support emergent literacy gains for those students. This study randomly assigned schools in a Southwestern U.S. state with English language learners (ELLs) in kindergarten and first grade to an experimental computer-assisted instruction (CAI) condition or a 'business as usual' control. The study tracked ELLs performance over one academic year using a nationally normed standardised reading test. The results demonstrated first-grade students in the experimental condition demonstrated greater gains compared with the control students in the domains of vocabulary, phonics, phonological awareness and text comprehension. Gains for kindergarten were less consistent; however, the lowest language proficient students using CAI experienced greater gains in vocabulary when compared with controls. Results extend prior studies targeting ELL students' reading skill development with targeted CAI interventions.

This study examined the effects of Reading Intervention for Adolescents, a 2-year extensive reading intervention targeting current and former English learners identified as struggling readers based on their performance on the state accountability assessment. Students who enrolled at three participating urban high schools were randomly assigned to the Reading Intervention for Adolescents treatment condition (n = 175) or a business-as-usual comparison condition. Students assigned to the treatment condition participated in the intervention for approximately 50 minutes daily for 2 school years in lieu of a school-provided elective course, which business-as-usual students took consistent with typical scheduling. Findings revealed significant effects for the treatment condition on sentence-level fluency and comprehension (g = 0.18) and on a proximal measure of vocabulary learning (g = 0.41), but not on standardized measures of word reading, vocabulary, or reading comprehension (g range: -0.09 to 0.06). Posthoc moderation analyses investigated whether initial proficiency levels interacted with treatment effects. On sentence-level fluency and comprehension and on vocabulary learning, initial scores were significantly associated with treatment effects--however, in opposite directions. Students who scored low at baseline on sentence reading and comprehension scored relatively higher at posttest on that measure, whereas students who scored high at baseline on the proximal vocabulary measure scored relatively higher at posttest on that measure. The discussion focuses on the difficulty of remediating persistent reading difficulties in high school, particularly among English learners, who are often still in the process of acquiring academic proficiency in English.

Schools in the Internationals Network for Public Schools (Internationals) are public middle schools, high schools, and academies (i.e., schools within schools) that serve secondary English language learners (ELLs)--in particular, ELLs who have been enrolled in U.S. schools for fewer than 4 years and who are at the lowest levels of English proficiency. With funding from a 5-year Investing in Innovation (i3) development grant from the U.S. Department of Education's Office of Innovation and Improvement, Internationals received an opportunity to implement key components of its model in comprehensive high schools that serve both ELLs and non-ELLs. Internationals designed an intervention--Project RISE (Realizing Instructional Supports for English Language Learners)--that aimed to improve the educational outcomes of ELLs in Grades 9-12 in two schools by changing teachers' instructional practices and several key structures in which students and teachers are organized. The American Institutes for Research (AIR), an external evaluator of Project RISE, was charged with providing both a formative evaluation and an impact evaluation. The purpose of this document is to summarize the findings of formative and impact evaluations of Project RISE. First, the report presents the results of the formative evaluation accumulated during the 4-year evaluation period while the project was being implemented. Then the report presents the results of the impact evaluation conducted after Project RISE was completed.

As originally conceptualized, Early Colleges were small schools focused purposefully on college readiness for all students. Frequently located on college campuses, Early Colleges targeted students who might face challenges in postsecondary education, including students who were the first in their family to go to college, economically disadvantaged students, English Language Learners (ELL), or students who are members of racial or ethnic groups underrepresented in college. The Early College Expansion Partnership (ECEP) is among the first large-scale effort to apply Early College strategies into comprehensive high schools. Supported by a $15 million grant from U.S. Department of Education's Investing in Innovation (i3) program, the ECEP was designed to increase the number of students graduating from high school prepared for enrollment and success in postsecondary education. The project sought to blend high school and college by applying strategies from the successful Early College high school model to 14 middle schools, 12 high schools, and two 6th-12th-grade schools in three districts in two states: Colorado and Texas. ECEP implemented an adapted version of the Early College High School Model. The program provided a set of services that supported implementation of a whole-school reform model emphasizing the creation of a college-preparatory school environment. A primary emphasis of the program was increasing the number of students who participated in college-credit-bearing courses while in high school. This report describes the approach used to assess student impacts and to track changes over time; uses survey and site visit data to describe key changes that have been made at the district and school levels; presents the impact estimates for the core student-level outcomes; places the findings in context and discusses the broader implications of this work; and summarizes the overall findings.

This study explores preliminary results from a pedagogical intervention designed to improve instruction for all students, particularly emergent bilinguals in the United States (or English language learners). The study is part of a larger efficacy randomized controlled trial (RCT) of the Instructional Conversation (IC) pedagogy for improving the school achievement of upper elementary grade students. Standardized achievement student data were gathered from (N = 74) randomized teachers' classrooms. Preliminary ordinary least squares analyses of the intervention appear promising for English language arts in general. Limitations in baseline equivalency for students after teacher randomization are discussed along with strategies to overcome them and implications concerned with the education of all students, notably those whose parents speak languages other than English at home.

We explore the potential of a computer-adaptive decoding game in Spanish to increase the decoding skills and oral reading fluency in Spanish and English of bilingual students. Participants were 78 first-grade Spanish-speaking students attending bilingual programs in five classrooms in Texas. Classrooms were randomly assigned to the treatment (i.e., where students played Graphogame Spanish) for 16 weeks for ten minutes per day (n = 3) versus business as usual instruction (n = 2). Results indicate that students at some risk on Spanish pseudoword reading appeared to benefit the most from playing the game. Analysis of gains suggests a potentially small, but meaningful educational effect of the game on Spanish oral reading fluency and English pseudoword reading when taking Spanish decoding skills at pretest into account. Students indicated that they enjoyed playing the game, and that the game helped them improve their reading skills. Teachers perceived the game as an engaging tool for students to use during small-group instruction or during independent time in a Response-to-Intervention approach. We discuss our mixed results in the context of using computer-adaptive games to improve the academic outcomes of bilingual students.

This study evaluated the effects of a cross-age peer learning program targeting vocabulary and comprehension in kindergarten and fourth-grade classrooms with substantial proportions of English Learners (ELs). The study followed a quasi-experimental design with 12 classrooms (6 kindergarten and 6 fourth grade) in the intervention group and 12 classrooms (6 kindergarten and 6 fourth grade) in the comparison group. Students were assessed before and after the 14-week intervention via curriculum-aligned and norm-referenced vocabulary and comprehension assessments. Findings of analyses of researcher-developed measures showed positive and significant intervention effects on receptive and expressive vocabulary in kindergarten and fourth grade and comprehension (i.e., understanding of text and strategy use) in fourth grade. Findings of analyses of norm-referenced measures showed positive and significant intervention effects on receptive vocabulary in kindergarten. In general, the intervention had similar effects for ELs and non-ELs.

examined among Spanish-speaking English-language learners in an English intervention (Grades 1–3) in the southwest United States. Path analysis revealed statistically significant transfers (ps < .05) for the treatment group from English reading comprehension to Spanish reading comprehension. English vocabulary and English grammar also had an indirect influence on Spanish reading comprehension through English reading comprehension. For the comparison group, no English to Spanish paths were statistically significant. We concluded that intervention activities in L2 influenced L1 reading even when L1 instructional time was reduced.

Inquiry-based learning methods, coupled with advanced technology, hold promise for closing the science literacy gap for English learners (ELs) and students with learning difficulties (SWLDs). Project ESCOLAR (Etext Supports for Collaborative Online Learning and Academic Reading) created collaborative online learning units for middle school science to meet the needs of ELs, SWLDs, and general education students. In a randomized controlled trial with 1,451 students, 28 teachers implemented one of two online units in their classrooms after completing a Web-based professional development course. Results showed that treatment condition students, including ELs and SWLDs, significantly improved science knowledge compared to controls; ELs' gains indicated a knowledge gap reduction compared to general education students. Findings suggest that quality science curriculum and effective technology practices can help all students learn science and prepare for future global scientific challenges.

Effectively educating the large English learner population requires policymakers to ensure developmentally appropriate settings and services throughout the time students are learning English, as well as during their transition to fluent English proficient status--a process termed reclassification. Using longitudinal student-level data from two U.S. states (N = 107,549), the authors implemented recent advances in multi-site regression discontinuity designs to assess the effects of reclassification policies across districts. They found that reclassification decisions are heavily influenced by state criteria; however, there is considerable variability across districts in the extent of state-level influence. The authors also found robust evidence of between-district heterogeneity in the effects of reclassification on subsequent achievement and graduation. They discuss the implications of these findings for reclassification policies and future research on the topic. Looking toward the next century of education research, the authors discuss ways that multi-site regression discontinuity designs can be combined with qualitative research to enable policymakers and practitioners to better understand variation in effects of policies across contexts as well as the mechanisms underlying those effects.

We examined the direct impact of an ongoing, intensive, and structured professional development (PD) within an English-as-second-language (ESL) instructional intervention on (a) teachers' time allocation in cognitive--academic language proficiency (CALP) and (b) Spanish-speaking English language learners' (ELLs) CALP development from the second to third grade within a multilevel cross-classified framework. Second, we explored the mediation effect of teachers' time allocation. We observed that treatment teachers spent more time in CALP than control teachers as a result of the instructional intervention with PD. In addition, the treatment effect was evident in ELLs' outcomes, including expressive vocabulary, oral reading fluency, and retell fluency. Finally, the treatment effect was completely mediated through teachers' time allocation in CALP in the second grade on retell fluency.

We present a community-based research project aimed at identifying effective methods and materials for teaching English literacy skills to adult English as a second language emergent readers. We conducted a quasi-experimental study whereby we evaluated the efficacy of two approaches, one based on current practices at the English Skills Learning Center (ESLC), and the other involving a number of innovative methods and materials. In addition, we collected written reflections from the instructors in the study and conducted interviews with the students. The qualitative and quantitative data together suggest that while both approaches led to student gains, the one based on current practices led to greater student gains.

The authors evaluated the effects of P-SELL, a science curricular and professional development intervention for fifth-grade students with a focus on English language learners (ELLs). Using a randomized controlled trial design with 33 treatment and 33 control schools across three school districts in one state, we found significant and meaningfully sized intervention effects on a researcher-developed science assessment and the state science assessment. Subgroup analyses revealed that the P-SELL intervention had a positive and significant effect for each language proficiency group (ELLs, recently reclassified ELLs, former ELLs, and non-ELLs) on the researcher-developed assessment. The intervention also had a positive effect for former ELLs and non-ELLs on the state science assessment, but for ELLs and recently reclassified ELLs, the effect was not statistically significant.

Nationwide, K-12 students designated as English language learners (ELLs) must learn both language and content simultaneously, and ELLs score far below the national average in math achievement. Many educators have suggested that identifying or developing teachers with skills specific to ELLs' instructional needs may be critical to addressing this challenge. This study seeks to identify the characteristics and learning experiences of general education teachers who are differentially effective at promoting math achievement among ELLs compared to non-ELLs. Our analyses indicate that individual teachers can learn specific skills that make them more effective with ELL students. In particular, prior experience teaching ELLs predicts improvements in novice teachers' differential instructional effectiveness with ELLs. We also find that both in-service and pre-service training focused on ELL-specific instructional strategies are associated with higher differential gains for ELLs. Our findings lend support to the notion that general education teachers can develop valuable ELL-specific instructional skills.

The recent increase in the number of students classified as English language learners (ELLs) has focused significant attention on reclassification policy, which governs the process by which ELLs move toward, and are deemed to reach, full English proficiency. In this paper, we draw on a data set containing annual individual-level records for every Wisconsin student ever classified as an ELL between the 2006-07 and 2012-13 school years to estimate the effects of being reclassified at the end of 10th grade--a crucial period on the pathway to postsecondary education--on several measures related to students' postsecondary attainments. We estimate these effects in a regression discontinuity framework, exploiting Wisconsin's policy rule that automatically reclassifies ELLs who score above a specified cutoff on the state's English language proficiency exam. Our analysis indicates that being reclassified as fully English proficient in 10th grade has a positive effect on students' ACT scores. It also provides some evidence of a positive effect on high school graduation and the probability of enrolling in a postsecondary institution the fall after graduation. Together, our analyses provide evidence on the effects of a policy directly relevant to the country's fastest growing student population, and we close the paper with a discussion of the implications for research and policy.
