The early course of language development among children from bilingual homes varies in ways that are not well described and as a result of influences that are not well understood. Here, we describe trajectories of relative change in expressive vocabulary from 22 to 48 months and vocabulary achievement at 48 months in two groups of children from bilingual homes (children with one and children wi...

Extensive evidence has suggested that early academic skills are a robust indicator of later academic achievement; however, there is mixed evidence of the effectiveness of intervention on academic skills in early years to improve later outcomes. As such, it is clear there are other contributing factors to the development of academic skills. The present study tests the role of executive function ...

This study investigated the differential effects of two direct instruction (DI) reading programs, one with overt decoding strategies and one with more covert decoding strategies, on the reading achievement of struggling seventh graders in an urban middle school. The students participating in this study (N = 55) were 2 to 4 years behind in reading achievement according to standardized pretests. ...

Abstract Reading in upper-elementary grades includes comprehending complex texts and learning disciplinary-specific vocabulary. This study aims to determine the effects of a computer-adaptive supplementary reading program on fifth-grade students’ achievement. Using propensity score matching create equivalent groups 450 students for both control intervention (N = 900), quasi-experimental design ...
