Though the immediate effect of Reading Recovery (RR) is both strong and well established, the longer term or sustained effect has been less studied and the evidence regarding it has been less conclusive. Michigan Reading Recovery students (n = 328) were compared to control students (n = 264) while in first (2009-2010), third (2011), and fourth…

Executive functions (EF) can be promoted by classroom interventions. Our study investigated whether (a) an intervention conducted by teachers improves EF in children; (b) there are effects on behaviour and academic achievement; and (c) there are stable benefits in a one-year follow-up. Fifty-eight first-graders, divided into experimental (EG = 28)…

The ability to flexibly approach the pronunciation of unknown words, or set "for variability", has been shown to contribute to word recognition skills. However, this is the first study that has attempted to teach students strategies for increasing their set for variability. Beginning readers (N = 15) were instructed to correct oral…

Introduction: In the present study we used a metaphorical representation in order to stimulate the numerical competences of six-year-olds. It was expected that when properties of physical action are used for mathematical thinking or when abstract mathematical thinking is grounded in sensorimotor processes, learning gains should be more pronounced…

We examined growth trajectories of writing and the relation of children's socioeconomic status and language and/or speech impairment to the growth trajectories. First-grade children (N = 304) were assessed on their written composition in the fall, winter, and spring, and their vocabulary and literacy skills in the fall. Children's SES had a…

This paper provides practical guidance for researchers who are designing and analyzing studies that randomize schools--which comprise three levels of clustering (students in classrooms in schools)--to measure intervention effects on student academic outcomes when information on the middle level (classrooms) is missing. This situation arises…

This study examined the effect of improvements in timing/rhythmicity on students' reading achievement. 86 participants completed pre- and post-test measures of reading achievement (i.e., Woodcock-Johnson III, Comprehensive Test of Phonological Processing, Test of Word Reading Efficiency, and Test of Silent Word Reading Fluency). Students in the…
