Project Activities
The research team planned to conduct a randomized controlled trial of Read It Again! with early childhood special educators and their students. They planned for two sequential cohorts of teachers to be assigned to a treatment or control condition and to participate during an initial implementation year followed by a maintenance year. Data were to be collected across a range of literacy outcomes at pretest and posttest for each cohort of participants, with hierarchical linear models to be used to compare the relative impacts of Read It Again! to the comparison condition on children's language, literacy, and school readiness outcomes.
Structured Abstract
Setting
The research will take place in early intervention settings in Ohio and Pennsylvania.
Sample
Participants will include 104 early childhood special education classroom teachers, approximately 600 children with disabilities, and 400 typically developing children.
Intervention
Read It Again! is a 60-lesson intervention delivered over a 30-week period in whole-class sessions that center around a teacher-led shared book reading. The core components of the intervention include: (1) addressing a systematic scope and sequence of instruction targeting four key areas of literacy development: narrative, vocabulary, phonological awareness, and print knowledge; and (2) embedding explicit language and literacy instruction within shared reading sessions, scaffolding the verbal participation and learning of children. The program is manualized, freely disseminated, and designed to promote high levels of implementation integrity.
Research design and methods
The research design involves a multilevel randomized controlled trial using a two-group pretest-posttest design to estimate the efficacy of Read It Again! on teacher and child outcomes. Two sequential cohorts of teachers and children will participate with approximately 100 teachers and an estimated 1,000 children sampled from their classrooms. Each cohort of teachers will participate for a 2-year period (an implementation year and a maintenance year) and fidelity of implementation will be measured during both years. Children will participate during the implementation year and then followed through kindergarten.
Control condition
In the control condition, approximately 50 teachers will implement their business-as-usual classroom programs and practices.
Key measures
Teacher measures include the Preschool Early Education Questionnaire, Teacher Knowledge Assessment Survey, Preschool Teacher Literacy Belief Questionnaire, and the Teacher Self-Efficacy Scale. The researchers will assess fidelity of implementation (e.g., adherence, exposure, program differentiation, and participant responsiveness) using lesson logs and videotaping of lessons along with a variety of specific fidelity measures developed for the Read It Again! program. The researchers will capture information about children's home literacy environments using the Home Literacy Environment survey and the Parental Reading Belief Inventory. Student print knowledge will be assessed using the Preschool Word and Print Awareness, the Alphabet Knowledge subtest of the Phonological Awareness Literacy Screening, and a short-form measure of letter-sound knowledge to assess children's understanding of basic letter-sound correspondences. Phonological awareness will be measured by the Pre-Reading Inventory of Phonological Awareness. Narrative will be measured by the Narrative Assessment Protocol. Language ability, including vocabulary, will be measured by three subtests of the standardized, norm-referenced Clinical Evaluation of Language Fundamentals-Preschool–2. The Definitional Vocabulary subtest of the Test of Preschool Early Literacy will be used as an additional measure of vocabulary to capture more decontextualized knowledge of words. To assess children's cognitive abilities, the researchers will use the Kaufman Brief Intelligence Test-2 Nonverbal subtest.
Data analytic strategy
Hierarchical linear models with children nested within classrooms will be used to compare the effect of the Read It Again! intervention to business as usual on children's language, literacy, and school readiness outcomes. For language and literacy outcomes, the researchers will analyze Read It Again! impact both at posttest and follow-up assessments using residualized change (posttest/follow-up scores controlling for pretest scores). For kindergarten readiness outcomes, the researchers will use children's initial language and literacy scores as covariates.
