Lesson Plan

Bierman et al. (2008) recruited two cohorts of four-year-olds over two years to participate in an evaluation of REDI. Significant treatment effects in pre-k were reported for two measures of literacy (mean ES = +0.31) and language (ES = +0.16). A follow-up of the Bierman et al. (2008) sample into kindergarten was reported by Bierman et al. (2014). ................
