Friday, November 12, 2021
11:00 am PT | 12:00 pm MT | 1:00 pm CT | 2:00 pm ET
Presenter: Dr. Mara Markinson

Summary: Results from a qualitative study about proof in high school geometry will be shared. First, a Common Core geometry textbook was analyzed for its proof-related contents. Then, inservice and preservice secondary mathematics teacher participants were administered a content assessment and interviewed regarding their knowledge, beliefs, and goals for teaching proof.

Registration Closed

Duration: 60 minutes

Format: Online seminar via Zoom web meeting software with questions and discussion. Detailed instructions for joining the seminar will be emailed to registered participants.
