Epistemological Frames and Physics Conditions

Assessments are crucial to education in the development of curricula and instruction as well as for assessing our learning goals. Recently, reports have elevated scientific practices to the same level of importance and emphasis as core ideas of physics. The Three-Dimensional Learning Assessment Protocol was released to evaluate if assessments satisfied these new goals. Our questions were developed based on this protocol and focused on the scientific practice of developing and using models based on concepts from the introductory physics sequence. We analyzed how the inclusion of a "physics condition", a condition written using physics terminology which corresponds to the real world situation occurring, affects the Students' Epistemological frames.

We used the frames given by Bing and Redish in figure 1 of Analyzing Problem solving using math in Physics:Epistemological Framing Via warrants. Bing and Redish found that mastering epistemological skills was necessary for complex problem solving in physics. Using thematic analysis we analyzed the transition of students between epistemological frames throughout the problem. From this study, we claim a "physics condition" provokes a frame shift for students. The following diagram shows the frame shifts we noticed as a result of this.

A diagram demonstrating the various frame shifts observed with thickness representing the number of students who completed this frame shift.

We still need to further study the reasoning behind these frame shifts. However, we have found assessment questions with a "physics condition" provoke frame shifts which have shown to be an essential component of complex physics problem solving. This provides us the capability to give students opportunities to think about physics in multiple ways, as well as information about students' processes.
