Abstract
Understanding rational numbers is critical for secondary mathematics achievement. However, students with mathematics difficulties (MD) struggle with rational number topics, including fractions, decimals, and percentages. The purpose of this systematic review was to describe the instructional foci of rational number interventions, determine the overall effect size, and explore potential moderators. Forty-three studies were included and 150 effect sizes were meta-analyzed using robust variance estimation. The majority of studies focused on teaching fraction magnitude and arithmetic. An overall effect size of g = 1.02 [0.80, 1.25] was found for rational number interventions favoring treatment conditions over business as usual control. Proximal measures contributed to higher effect sizes than distal measures. Limitations included a high number of fraction interventions contributing to the overall effect size and a large amount of heterogeneity among study effect sizes.
期刊介绍:
Remedial and Special Education (RASE) is devoted to the discussion of issues involving the education of persons for whom typical instruction is not effective. Emphasis is on the interpretation of research literature and recommendations for the practice of remedial and special education. Appropriate topics include, but are not limited to, definition, identification, assessment, characteristics, management, and instruction of underachieving and exceptional children, youth, and adults; related services; family involvement; service delivery systems; legislation; litigation; and professional standards and training.
