While students can learn both chemistry content and inquiry practices by participating in course-based undergraduate research experiences (CUREs), it is well documented that prior experiences shape perception. We conducted a case study to investigate students’ first experiences with a CURE in an upper-division chemical engineering laboratory course, drawing upon interviews (n = 6), field notes, and written reflections (N = 31). We used discourse analysis to characterize students’ agency as they navigated their uncertainty and made sense of the authentic research. We found that students’ past experiences shaped their expectations about the CURE, with some wishing for traditional learning supports misaligned to CUREs. Offering students constrained yet consequential agency allowed them to recognize the authentic supports that were available, including help-seeking as itself a form of agency; understand failure as endemic to research rather than their own shortcoming; and position themselves as capable of navigating the uncertainty as a community of researchers. Our results suggest that instructors should model uncertainty and failure as endemic to research and position students as valued collaborators and support for overcoming abundant prior experiences with cookbook-style experiments. 

Laboratory experimentation is a key component of the development of professional engineers. However, experiments conducted in chemical engineering laboratory classes are commonly more prescriptive than the problems faced by practicing engineers, who have agency to make consequential decisions across the experiment and communication of results. Thus, understanding how experiments in laboratory courses vary in offering students opportunities to make such decisions, and how students navigate higher agency learning experiences is important for preparing graduates ready to direct these practices. In this study, we sought to answer the following research question: What factors are measured by the Consequential Agency in Laboratory Experiments survey? To better understand student perceptions of their agency in relation to laboratory experiments, developed an initial version of the Consequential Agency in Laboratory Experiments survey, following research-based survey development guidelines. We implemented it in six upper-division laboratory courses across two universities. We used exploratory factor analysis to investigate the validity of the data from the survey for measuring relevant constructs of authenticity, agency in specific domains, responsibility, and opportunity to make decisions. We found strong support for items measuring agency as responsibility, authenticity, agency in the communication domain, agency in the experimental design domain, and opportunity to make decisions. These findings provide a foundation for developing a more precise survey capable of measuring agency across various laboratory experiment practices. Such a survey will enable future studies that investigate the impacts of increasing agency in just one domain versus in several. In turn, this can aid faculty in developing higher agency learning experiences that are more feasible to implement, compared to authentic research experiences.
