| Abstract Title: | Evaluating impact of GTA training in a mixed-reality classroom simulator |
|---|---|
| Abstract: | We evaluate the impact of rehearsing teaching skills in a classroom simulator on GTAs' instructional practices in combined tutorial and laboratory sections of an algebra-based introductory physics sequence over three semesters. GTAs participated in different numbers of simulator rehearsal sessions across the three semesters: no simulator training, one session, and four sessions. We conducted 109 classroom observations for 23 GTAs, using a modified version of Laboratory Observation Protocol for Undergraduate STEM (LOPUS). To classify and characterize GTAs' instructional practices, we conducted a hierarchical cluster analysis and found three instructional styles: "the group-work facilitators", "the whole-class facilitators", and "the waiters." These instructional styles vary in multiple GTA codes, including amount of wait time and posing questions in small groups and whole class. We discuss the characteristics of the instructional styles, distributions of GTAs' use of the styles in each semester, and the correlation between student learning outcomes and GTA instructional styles. |
