  Abstract: The Learning Assistant (LA) Model allows instructors to implement a variety of research-based instructional strategies in their classrooms. While there are some similarities across all uses of LAs, there are also many differences. This presentation focuses on the influence of the LA program on course-level DFW rates in introductory physics, chemistry, and calculus courses at the University of Colorado Boulder. We will also discuss impacts on six-year graduation. We find that the LA program has differential effects across departments and that both quantitative and qualitative investigation is necessary to understand the effectiveness of the LA Model. Possible reasons for differential effects will be discussed. We will also provide general guidelines regarding the process for conducting similar analyses, including an explanation of relevant statistical models.
