Many children fail to acquire basic reading skills. The current evidence base for supplementary reading instruction indicates that explicit, systematic and intensive instruction in the early years for children considered to be "at-risk" of reading difficulties can have significant and preventative effects on reading skills. However,…

The purpose of this varied replication study was to evaluate the effects of a supplemental reading intervention on the beginning reading performance of kindergarten students in a different geographical location and in a different instructional context from the initial randomized trial. A second purpose was to investigate whether students who…

"Reading Recovery[R]" is a short-term intervention that provides one-on-one tutoring to first-grade students who are struggling in reading and writing. The supplementary program aims to promote literacy skills and foster the development of reading and writing strategies by tailoring individualized lessons to each student. Tutoring is…

This study compared the effects of 2 supplemental interventions on the beginning reading performance of kindergarteners identified as at risk of reading difficulty. Students (N = 206) were assigned randomly at the classroom level either to an explicit/systematic commercial program or to a school-designed practice intervention taught 30 min per day…

Alphabet knowledge is a hallmark of early literacy and facilitating its development has become a primary objective of preschool instruction and intervention. However, little agreement exists about how to promote the development of alphabet knowledge effectively. A meta-analysis of the effects of instruction on alphabet outcomes demonstrated that…

What beginning reading programs have been proven to help students in grades K-1 to succeed? To find out, this review summarizes evidence on four types of programs designed to improve beginning reading achievement: (1) Reading Curricula (Curr), such as "Open Court Reading," "Reading Street," and other standard and alternative textbooks; (2)…

Reviews 42 studies of computer-assisted instruction published from 1990 to the present, comprising 75 experimental comparisons. The corrected effect size estimate was 0.19. Two variables, effect size at the time of pretesting and language of instruction, accounted for 61% of the variability in effect sizes. Advises caution in interpreting results…
