This meta-analysis is the first to provide a quantitative synthesis of empirical evaluations of mathematical intervention programs implemented in secondary schools for students with learning disabilities and mathematics difficulties. Included studies used a treatment-control group design. A total of 19 experimental and quasi-experimental studies…

This randomized controlled study investigated the efficacy of a Tier 1 intervention--schema-based instruction--designed to help students with and without mathematics difficulties (MD) develop proportional reasoning. Twenty seventh-grade teachers/classrooms were randomly assigned to a treatment condition (schema-based instruction) or control…

Schools continue to strive for the use of evidenced-based interventions and policies to foster well-managed classrooms that promote improved student outcomes. The present study examined the effects of the Class-Wide Function-related Intervention Teams (CW-FIT), a group contingency intervention, on the on-task and disruptive behavior of elementary…

The purpose of this study was to determine the efficacy of specific, individualized training for students with different levels of mathematical difficulties. Fifty-four students, with either severe or mild math difficulties, were assigned to individualized training or to a control condition. Ten students with severe math difficulties…

This study investigated the role of strategy instruction on solution accuracy in children with and without serious math difficulties (MD) in problem solving. Children's posttest solution accuracy was compared on standardized and experimental measures as a function of strategy conditions. Strategy conditions included curriculum materials that…

Promoting self-determination has become a best practice in special education. There remains, however, a paucity of causal evidence for interventions to promote self-determination. This article presents the results of a group-randomized, modified equivalent control group design study of the efficacy of the Self-Determined Learning Model of…

In this research we evaluated two methods to improve the reading fluency of struggling readers. Poor readers in Grades 2 and 4 with (n = 17) and without (n = 20) learning disabilities were randomly assigned to one of two fluency practice variations or to a control group. Students in the treatments practiced reading aloud under repeated or…

This study determined the effectiveness of Kindergarten Peer-Assisted Learning Strategies (K-PALS) for English Learners (ELs). We compared 20 K-PALS ELs to 20 Control ELs and to 20 K-PALS non-ELs on early reading skill acquisition, using a pretest-posttest control group design with matched samples. We also compared proportions of ELs unresponsive…
