Characteristics of study sample as reported by study author.
| Other or unknown | 100% |
The study took place in 78 schools in 10 districts in Texas across urban (10%), suburban (50%), small town (10%), and rural (30%) sites. Study schools in the study sample served a predominantly low-income (91%) and English learner (EL) student population (62%).
The sample was 100% EL students. The majority of students in the study were in transitional bilingual classrooms and the teachers were all English as a second language (ESL) teachers. Only EL students and students who did not qualify for special education services were recruited for the study. No student-level demographic information was provided in the study.
English Language and Literacy Acquisition-Validation (ELLA-V) provided ongoing virtual professional development and coaching and curricula to teachers of English learner (EL) students in 10 school districts at 78 schools in Texas. The evaluation included two treatment groups that provided similar professional development and coaching but different curricula for teachers. Treatment 1 included science-infused literacy curriculum, while Treatment 2 included science-infused oral language curriculum. The evaluation examined the effectiveness of ELLA-V in promoting K-3 students’ overall academic growth in science, oral language, phonological awareness, reading, writing, and English language acquisition; student self-esteem; and teachers’ quality of instruction after one year of exposure in each of four grades.
Teachers in the comparison condition had access to the standard professional development, coaching, and curricular resources provided by the school and district. Comparison students were likely exposed to instruction and support services as they had been in the past.
No implementation support was described separate from the intervention components, which included professional development, coaching, and curricula.

Characteristics of study sample as reported by study author.
The study sample included 79 schools in 10 districts in Texas across urban, suburban, small town, and rural sites. English learner students in both structured English immersion and transitional bilingual programs received the intervention during a 75-minute ESL block in kindergarten and 90-minute ESL block in grades 1–3, while the typical state-mandated ESL block was 45 minutes. Comparison students received instruction in a business-as-usual format (i.e., non-enhanced 45-minute ESL learning block). In each school, there were at least two teachers who were certified in bilingual education. Students in grades K–3 were English learners and did not qualify for special education services.
No student demographic information was reported. However, for the ten schools, 62% of the student population were English learners, 91% were low income, and 76% had an English language proficiency rating of intermediate or advanced. The majority of students in the study were in transitional bilingual classrooms. Students were recruited only if they were English learners and did not qualify for special education services.
ELLA-V provided ongoing virtual professional development and coaching and curricula to teachers of English learner students. ELLA-V was implemented in grade 3 in 2013–14, grade 2 in 2014–15, grade 1 in 2015–16, and kindergarten in 2016–17. Teachers received the intervention for a single year, dependent on grade-level implementation. The curricula used by the teachers differed across grade levels, but all focused on literacy and science content. For Treatment 1, which is the focus of this review, reading was a focus across the grade, compared to Treatment 2's focus on oral language development. Across grades, the curricula for Treatment 1 included Lets Talk Science (LTS), Early Interventions in Reading (EIR-I and EIR-II), and Content Reading Integrating Science for English Language and Literacy Acquisition (CRISELLA). Students in both structured English immersion and transitional bilingual programs received the intervention during a 75-minute ESL block in kindergarten and a 90-minute ESL block in grades 1–3, while the typical state-mandated ESL block was 45 minutes (p.8).
The comparison condition consisted of teachers of English learner students in each of the four grade levels who may have received professional development, coaching, and used curriculum materials other than those available through ELLA-V (i.e., non-enhanced 45-minute ESL learning block).
Each school year, intervention teachers in the target grade level received bimonthly 90-minute virtual professional training for 18 sessions between September and May. Intervention teachers were also supported by coaches and observed up to three times a year depending on teacher needs. Coaches provided feedback to teachers specific to teaching English learners. Finally, teachers were provided with curricula that reflected pedagogical best practices and were aligned with content-area standards and the instructional models used in the teacher professional development.
An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
