Abstract

This mixed methods design study explored the effectiveness of hands-on and virtual manipulatives in advancing preservice teachers’ understanding of the algebraic concepts of linear function and slope. The quantitative data analysis suggested that participants benefited from the virtual and hands-on manipulative interventions as to their understanding of linear function and slope. A further qualitative analysis engendered a surprising conclusion: the interventions had nothing to do with preservice teachers’ learning, but provided a context for peer discussion. Based on data from the after-intervention interviews and follow-up questionnaires, the results suggest that peer discourse maybe a more effective strategy in advancing preservice teachers’ grasp of specific points in mathematics.
