Mathvision

eric.ed.gov har udgivet: We report on the development and evaluation of MathVision, a mobile-application designed to develop Virtual Professional Learning Communities through asynchronous discussion about 2nd, 3rd, 4th, and 5th grade students’ mathematical thinking. MathVision allows teachers to upload videos of problems solving sessions using Cognition Based Assessment tasks and foster discussion aligning those strategies to research-based learning progressions for Length and Measurement. Our findings indicate that while it was possible to develop such an interface, sparking productive online discussion was difficult. The application served as a tool for enhancing physical teacher meetings and drawing attention to student thinking consistent with conducting task-based interviews, rather than actually facilitating this talk entirely.
