Modeling in Project-Based Labs

Open-ended lab activities are beneficial for students' learning and their beliefs and attitudes about experimental physics. In particular, student-designed multiweek projects are an increasingly common feature in advanced lab courses, where students can design their own questions, experimental procedures, and analysis methods as they engage in authentic experimental practices. In this context, we investigate students' engagement with modeling and their views about the process of experimental physics. 

In our study, advanced lab students from three different institutions in the US viewed the Experimental Modeling Framework (EMF) as an accurate reflection of the process of experimental physics and recognized that the traditional, linear depiction of the "scientific method" can be misleading. This work suggests that open-ended projects can provide opportunities for students to experience the iterative nature of experimental physics, and that, depending on specific course goals, it may be beneficial to engage in explicit reflections and discussions with students about the role that iteration plays in the process of experimental physics. 

Goals for ongoing analysis include investigating how students engage in modeling in their multiweek self-designed projects, what features of the projects lead to student engagement with different aspects of the Experimental Modeling Framework, and how students' views of experimental physics correlate with the amount and/or the kind of modeling they do.
