Problem Solving for Teachers – Action Research in a Cross-Listed Undergraduate and Graduate Course

This article describes a course-based research experience in a cross-listed mathematical problem solving course for middle school pre-service and in-service teachers. The course was conducted entirely online due to statewide and university restrictions during the coronavirus pandemic. This study examines 4 undergraduate and 5 graduate students’ understanding of mathematical modeling. Undergraduate and graduate students were paired in groups to develop open-ended model-eliciting activities for their classmates to solve, and groups conducted educational action research to analyze their classmates’ work on the activities. We present one group’s activities and their results as an example of how action research can be conducted in a virtual teaching environment
