Re-imagining Video-Based Online Learning


2015 (see original presentation & discussion)

Grades 6-8, Grades 9-12

The familiar YouTube-style videos of solutions to math problems have been used world-wide to help students learn basic math. The NSF project, Re-imagining Video-Based Online Learning, based at San Diego State University, is creating a model of online videos that embodies a more expansive vision of both the nature of the content and the pedagogical approach. Rather than the procedurally-oriented expository approach of videos that dominate the internet, the videos produced for this project focus on developing mathematical meanings and conceptual understanding. They feature pairs of students, highlighting their dialogue, explanations, and alternative conceptions. The initial work is being done on a unit for high school students on geometric-algebraic connections with parabolas and on a unit for middle school students on proportional reasoning. Despite the tremendous growth in the availability of mathematics videos online, little research has investigated student learning from them. Consequently, a major contribution of the future work of this project will be a set of vicarious learning studies.
