Research suggests learning assistant (LA) programs can be a change lever to support the institutionalization of active learning in postsecondary education. Some research suggests LAs offer unique benefits for STEM courses, independent from other change levers, but more research needs to be done to understand how LAs support active learning…

The use of student-centered instruction or active learning has been linked to higher rates of student success compared to traditional lecture. However, a mechanistic understanding of why active learning "works" has proven elusive. This dissertation explores active learning in Learning Assistant supported courses and makes the case for…

Across the nation, there is increasing national interest in improving the way mathematics departments prepare their graduate teaching assistants (GTAs) because of their integral role in teaching lower division mathematics courses, particularly within the Calculus sequence (Speer, Deshler, & Ellis, 2017). While there have been several studies…

It has been well-establishing in the field of educational research that traditional educational methods such as passive lectures and labs where students follow pre-designed procedures to verify information already told to them are not effective for promoting meaningful and lasting conceptual understanding. Alongside this knowledge have come a…

This thesis explores impact of evidence-based active-engagement courses (EBAE) on student achievement and gender gap in introductory physics. The first study is about the pedagogical content knowledge (PCK) of the physics teaching assistants (TAs) at identifying introductory students' difficulties using the Conceptual Survey of Electricity and…

This study investigated the design, enactment, and impact of an undergraduate, inquiry-based astronomy laboratory learning environment. The professor, Richard, adopted laboratory materials from the Center for Astronomy and Physics Education Research [CAPER] which were described by the group as inquiry-based. Students worked through these…
