Title:  WWC Review of the Report “Longitudinal Evaluation of a Scale-Up Model for Teaching Mathematics with Trajectories and Technologies”
Description: The 2012 study, Longitudinal Evaluation of a Scale-Up Model for Teaching Mathematics with Trajectories and Technologies, examined the effects of Technology-enhanced, Research-based, Instruction, Assessment, and professional Development (TRIAD), a math intervention for preschoolers that combines a curriculum, a software-based teaching tool, and in-person teacher professional development. TRIAD is designed for young children, particularly those at risk of low math achievement. The study also included an assessment of whether continuing the intervention through kindergarten improved math achievement at the end of kindergarten. To measure the impacts of the program, researchers randomized 42 schools to implement TRIAD or to not implement TRIAD. The researchers then assessed the math achievement of 963 children from 42 schools at the start of preschool (prior to intervention), at the end of preschool (after 1 year of study participation), and at the end of kindergarten (after 2 years of study participation). The study found that the TRIAD intervention had positive effects on student math performance. The study meets WWC group design standards with reservations because it is a randomized controlled trial that demonstrates baseline equivalence but has unknown levels of study attrition.
