Lessons Learned from using FullProof, a digital proof tool, in a Geometry for Teachers Course

Presenters: Orly Buchbinder, Sharon Vestal, & Tuyin An

Summary: Proof-writing is a core practice of mathematicians and a crucial skill every future teacher and mathematics major needs to acquire. A proof-based geometry course provides a fruitful ground for developing proof-writing skills. Despite recent pedagogical and technological advances proof remains difficult to learn and to teach. We conducted a pilot study to explore potential advantages of an innovative digital proof tool FullProof, which was developed with an exclusive goal of advancing students’ proof-writing skills in Euclidean Geometry. We integrated the FullProof tool with three Geometry (for Teachers) courses at three universities: Georgia Southern University, South Dakota State University, and the University of New Hampshire. In this talk, we report on the findings pertaining to students’ interactions with FullProof, their perceptions of the usefulness of this digital tool to their proof-writing skills, and the lessons learned from the FullProof integration in a Geometry course from an instructor perspective.

Registration Closed

Orly Buchbinder is an Associate Professor of Mathematics Education at the Department of Mathematics and Statistics at the University of New Hampshire (UNH), where she teaches a variety of courses in both mathematics and mathematics education. Her research agenda is focused on teaching and learning of reasoning and proving at the secondary level. In particular, supporting current and prospective secondary teachers to teach mathematics via reasoning and proving. Prior to joining UNH, she received her PhD in Mathematics Education from Technion, Israel Institute of Technology, and completed a three-year postdoctoral fellowship at the University of Maryland.

Sharon Vestal  is an Associate Professor in the South Dakota State University (SDState) Department of Mathematics and Statistics, where her teaching and research focus is preparation of high-quality secondary mathematics teachers. She holds an MA in Mathematics from the University of South Dakota, Vermillion, SD, and a PhD in Mathematics from the University of Colorado-Boulder.  Since arriving at SDState, she has served as PI on three NSF Robert Noyce Scholarship grants, totaling over $2.3 million in funding. 
Tuyin An is an Assistant Professor of Mathematics Education at Georgia Southern University (GS). She is interested in teaching and learning of mathematical reasoning and proof and pre-service mathematics teachers’ content knowledge. She is a Service, Teaching, and Research (STaR) Fellow in the Association of Mathematics Teacher Educators (AMTE), a Project NExT (New Experiences in Teaching) Fellow in the Mathematical Association of America (MAA), and a Scholarship of Teaching and Learning (SoTL) Fellow at GS, during 2018-2019. She earned her M.A. in Mathematics Education from New York University and Ph.D. in Mathematics Education from Purdue University.
