Interventions to Improve Fraction Skills for Students With Disabilities: A Meta-Analysis

Academic Article

Abstract

  • Proficiency with fractions is one of the most significant predictors of later mathematics achievement. However, there are currently no meta-analyses that assess the literature base on fractions for students with or at risk for disabilities using quality indicators. We applied the 2014 Council for Exceptional Children Standards for Evidence-Based Practices in Special Education (CEC EBP) to 21 studies, both single-case and group designs, with instructionally based fraction interventions, published from 1986 to 2017. Ten of the included studies met all of the CEC EBP quality indicators, and effect sizes ranged from g = 0.42 to 11.51 across interventions. Publication bias was mixed but limited across the research base. Included studies examined the effects of anchored instruction, explicit instruction, graduated instruction, strategy instruction, and video modeling; explicit instruction was determined to be an evidence-based practice when applying the CEC EBP standards. We offer limitations and directions for future research in this area.
