Effectiveness of a Program to Accelerate Vocabulary Development in Kindergarten (VOCAB): First Grade Follow-Up Impact Report and Exploratory Analyses of Kindergarten Impacts. Final Report. NCEE 2012-4009
This study is the first randomized study of the impacts of the vocabulary instruction program Kindergarten PAVEd for Success (K-PAVE) (Hamilton and Schwanenflugel 2011) on low-income students in kindergarten and grade 1. The study has two components. The first component is a test of the impacts of one year of the K-PAVE vocabulary instruction in kindergarten, before students have encountered formal reading instruction (the kindergarten study). The second component is a test of whether the effects of the vocabulary instruction in kindergarten are sustained beyond the intervention period, in grade 1 (the grade 1 follow-up study). This report presents the findings from the grade 1 follow-up study, which followed students who were part of the kindergarten sample into grade 1. During grade 1, no students received K-PAVE; the study was designed to determine whether the impacts found at the end of kindergarten were sustained in grade 1. The report also presents supplemental findings on impacts at the end of kindergarten and discusses outcomes that were not addressed in the kindergarten report. Appended are: (1) K-PAVE Materials Provided to Teachers; (2) Sample Weekly Unit from K-PAVE Program; (3) List of K-PAVE Target Words; (4) Mississippi Counties with Study Schools; (5) Exploratory Analyses of Kindergarten Impacts on Components of Classroom Vocabulary and Comprehension Support, Student Lexical Diversity, and Teacher Lexical Diversity; (6) Statistical Power Analysis; (7) Random Assignment; (8) Recruitment and Random Selection of the Student Sample; (9) Comparison of Students Missing and Not Missing Baseline Assessment; (10) Model Specifications; (11) Sensitivity Analyses; (12) Imputation of Missing Data; (13) Data Collection Procedures; (14) Data Quality Assurance Procedures; (15) School, Teacher, and Student Covariates; (16) Unadjusted Sample Means and Standard Deviations for Outcome Measures; (17) Classroom Observation Measures Used to Create Vocabulary and Comprehension Support Outcome Variables; and (18) Teacher Survey. (Contains 6 figures, 53 tables, 1 map and 69 footnotes.)
