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.

Student agency in chemical engineering laboratory courses across two institutions
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 questions: How do students perceive their agency in course-based undergraduate research experiences? 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, we first conducted a case study of a course-based research experience (CURE) in a senior-level chemical engineering laboratory course. We then surveyed six upper-division laboratory courses across two universities using an initial version of the Consequential Agency in Laboratory Experiments survey. 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 that with instructional support, students in the CURE recognized that failure could itself provide opportunities for learning. They valued having the agency to make consequential decisions, even when they also found the experience challenging. We also 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 give us insight into the value of higher agency laboratory experiments, and they 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 CUREs.

null (Ed.)In response to the outbreak of COVID-19 the national landscape of higher education changed quickly and dramatically to move “online” in the Spring semester of 2020. While distressing to both faculty and students, it presents a unique opportunity to explore how students responded to this unexpected and challenging learning situation. In four undergraduate STEM courses that incorporated course-based undergraduate research experiences (CUREs)—which are often focused on discovery learning and laboratory research—we had an existing study in progress to track students' interest development at five time points over the Spring 2020 semester. Via this ongoing study we were able to investigate how students stay engaged in their college science courses when facing unexpected challenges and obstacles to their learning. Longitudinal survey data from 41 students in these CURE courses demonstrated that students' situational interest dropped significantly when their CURE courses unexpectedly shifted from hands-on, discovery-based, and laboratory-based instruction to online instruction. Although we observed a dramatic decline in student interest in general after the CURE courses moved fully online, the decline rates varied across students. Students who were able to make meaningful connections between the learning activities and their personal or career goals were more likely to maintain a higher level of interest in the course. Implications for practice are discussed.more » « less

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.more » « less
