Evaluation of Around the Corner

(Purpose) The purpose of this study was to understand if inclusion of computer activities and videos for pre-K and kinder students, with opportunities to view these videos again at home, providing a repeated learning experience with language concepts and vocabulary, improved young students' early reading skill. (Methods) The study followed one cohort of students over two years. Students who were in preschool in the 2014-15 school year and who progressed into kindergarten in the 2015-16 school year were included. The outcome measures for the impact study were tests that gauge students' language development and early reading skills. These included the Woodcock-Johnson III Tests of Achievement subtests: Letter-Word ID and Word Attack, the Peabody Picture Vocabulary Test, and the Test of Language Development-4, Sentence Imitation subtest. (Results) There were no statistically significant differences between ATC and control students in early reading skills, as measured by the confirmatory outcome measure. We also found no statistically significant differences between ATC and control students on additional post-tests analyzed for exploratory purposes. (Implications) The findings of the impact study suggest that the evaluation study may have been underpowered and that the effect of ATC on some measures of early reading skills compared with the business-as-usual condition may be directionally positive on average but less than 0.20 standard deviations. More research is needed with larger sample sizes and lower minimally detectable effect sizes. Another limitation of this study is that the business-as-usual condition consisted of programs that are, at least in some ways, similar to the ATC intervention. Thus, the effect size of ATC may be much greater in a context where ATC participation is compared with a lower quality preschool or kindergarten program. Supplemental tables are appended.
