Abstract Title: Instructors' Use of Specific Design Features in Example Solutions
Abstract: In light of recommendations from the literature for modeling expert-like problem solving approaches, we investigated how instructors use example solutions in teaching introductory physics. Twenty-four graduate teaching assistants and thirty physics faculty were asked to discuss their preferences for different solution features they observed in three example solutions provided. Data analysis focused on understanding instructors' considerations when using example solutions and how these considerations were manifested through the solution features they valued and used. We found that while TAs consider helping students develop expert-like problem solving approaches when choosing example solution for their students, they do not notice many features described in the literature as supportive of this goal, and use even fewer of these features. Differences between the faculty and TAs will be discussed in order to describe possible progression of ideas throughout an instructor's professional career.
