Dataset
Part of Project: Project KIDS
Description: These data are for each item on all achievement and behavioral assessments completed during the original intervention projects. The dataset is wide, with separate variable names for each wave of assessment. All participants (n= 4,038) are included. These data can be linked to the "total level" data using the PK_ID variable.
Dataset
Part of Project: Math Achievement, Attitudes, and Anxiety
Description: Mathematics achievement, attitudes, and anxiety were longitudinally assessed for 342 (169 boys) adolescents from 7th to 9th grade, inclusive, and Latent Growth Curve Models were used to assess the relations among these traits and developmental change in them.
Dataset
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.
