Animated Contrasting Cases to Improve Procedural and Conceptual Knowledge in Geometry (AC²inG)
Have you ever tried to identify the type of poison ivy in your yard? Or tried to teach a one-year-old the difference between red and blue? Often this learning occurs by directly comparing the poisonous leaf to ones in a magazine or showing the child something blue along with something red. Comparing and contrasting objects is a powerful learning tool with deep roots in cognitive science. The purpose of our research is to design curricular materials for geometry that focus on comparing different approaches to solving the same problem, and to examine the effects of these materials on student learning.
Assistant Professor Erin Krupa Hopes to Help Students Better Understand Geometry Through $450,000 NSF Grant
Could the use of animated materials in contrasting cases help middle school students develop a stronger understanding of geometry? NC State College of Education Assistant Professor of Mathematics Education Erin Krupa will use a $450,000 NSF grant to find out.
