CompassLearning Odyssey Math

CompassLearning Odyssey Math is a computer-based mathematics instructional software designed to improve math learning for grade 4 students. The software consists of web-accessed learning activities, assessments, and math tools delivered through individualized instruction. In this study, Odyssey Math was implemented as a partial substitute for the standard math curriculum, with teachers advised to use it for 60 minutes per week. Students accessed the software individually on computers with headphones, working through multimedia-based interactive learning activities, practice tasks with feedback, and built-in assessments. The software allows teachers to select activities for students or let the software assess each student's skill level and place them in appropriate learning activities. Intervention teachers received five 'days' of professional development, consisting of two large group sessions (covering software navigation, curriculum components, tests, and assessments) and three one-on-one in-class coaching sessions (covering startup, management, incorporating Odyssey Math into lesson plans, developing assessments, and scaffolding assignments).
