FullProof Mixed Methods Data

Proof writing is a core practice of mathematicians and a crucial skill every mathematics major and future secondary mathematics teacher needs to acquire. A proof-based geometry course is a fruitful ground for developing these proof writing skills. Despite recent pedagogical and technological advances, proof remains challenging to learn and teach. An innovative, AI-based digital platform, <i>FullProof, </i>was designed specifically to advance students’ proof writing skills in Euclidean Geometry. We integrated <i>FullProof </i>in college geometry courses at three universities for three years. We conducted a mixed-methods research study to explore the effects of using the <i>FullProof </i>digital proof platform on undergraduate students’ perceived competence and confidence in writing geometry proofs. We report on the findings about students’ interactions with this tool, their thoughts on using the tool, and their general perceptions on whether there was an improvement in their comfort level with proofs, engagement with proofs, proof understanding, and beliefs about proofs.
