I gathered 77 randomized experiments (with 111 treatment arms) that evaluated the effects of school-based interventions on learning in developing-country primary schools. On average, monetary grants and deworming treatments had mean effect sizes that were close to zero and not statistically significant. Nutritional treatments, treatments that…

The authors conducted a synthesis of studies of reading comprehension interventions for middle school students (Grades 6-8) identified with a learning disability. They identified 12 studies between 1979 and 2009 with treatment and comparison designs and 2 single-participant studies. Findings from the studies indicate large effect sizes for…

Although science has received much attention as a political and educational initiative, students with learning disabilities (LD) perform significantly lower than their nondisabled peers. This meta-analysis evaluates the effectiveness of instructional strategies in science for students with LD. Twelve studies were examined, summarized, and grouped…

Background: Many countries rely on immigrants for population growth and to maintain a skilled workforce. However, many such immigrants face literacy-related barriers to success in education and in the labour force. Aims: This meta-analysis reviews experimental and quasi-experimental studies to examine strategies for teaching English literacy to…

This systematic review of algebra instructional improvement strategies identified 82 relevant studies with 109 independent effect sizes representing a sample of 22,424 students. Five categories of improvement strategies emerged: technology curricula, nontechnology curricula, instructional strategies, manipulatives, and technology tools. All five…

Problem-based learning (PBL) is a teaching/learning strategy through which students learn course content by solving real-world problems associated with the course material. Although the benefits of PBL have been amply demonstrated in the medical field and other selected subject areas, few studies have examined PBL's potential contributions in…
