Part of Project: Developing connections between word problems and mathematical equations to promote word-problem performance among students with mathematics difficulty
Description: The purpose of this study was to explore the paths by which word-problem intervention, with versus without embedded pre-algebraic reasoning instruction, improved word-problem performance. Students with mathematics difficulty (MD;n304) were randomly assigned to a business-as-usual condition or 1 of 2 variants of word-problem intervention.
