Abstract:
|
As part of a larger study to understand how instructors make teaching decisions, we investigated how graduate teaching assistants (TA's) perceive features of written problem solutions. TAs are an important population to understand; they often provide significant instruction and they also represent the pool of future physics faculty. Twenty-four first-year graduate TA's enrolled in a training course were provided with different instructor solutions for the same physics problem and asked to discuss their preferences for prominent solution features. Preliminary findings reveal that providing a schematic visualization of the problem, listing knowns/unknowns, and explaining reasoning in explicit words were the most valued features. Preferences for different features were sometimes in conflict with each other. For example, while the TA's valued solutions where reasoning was explicitly explained, they also valued concise solution. We'll present the reasons behind these preferences and discuss the implications for the professional development of physics TA's.
