Eric.ed.gov – Mathvision: A Mobile Video Application for Math Teacher Noticing of Learning Progressions

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.

Jeg er ansat som adjunkt hos Læreruddannelsen i Jelling, hvor jeg underviser i matematik, specialiseringsmodulet teknologiforståelse, praktik m.m. Jeg har tidligere været ansat som pædagogisk konsulent i matematik og tysk hos UCL ved Center for Undervisningsmidler (CFU) i Vejle og lærer i udskolingen (7.-9. klasse) på Lyshøjskolen i Kolding. Jeg er ejer af og driver bl.a. hjemmesiderne www.lærklokken.dk og www.iundervisning.dk, ggbkursus.dk og er tidligere fagredaktør på matematik på emu.dk. Jeg går ind for, at læring skal være let tilgængelig og i størst mulig omfang gratis at benytte.
