   Introductory physics lab courses aim to have students gain a wide variety of skills and knowledge, including developing views of the nature of experimental physics that are aligned with common expert views. The large introductory lab course ( 700 students) at the University of Colorado Boulder has been recently transformed to explicitly address this goal among others. To measure the level of success in reaching this goal, we used an established assessment instrument, the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS), which probes students’ views and expectations of experimental physics. We collected students’ responses to E-CLASS during three semesters before, and four semesters after, the course transformation. We observe statistically significant differences between the before and after transformation post-test scores of the (i) overall E-CLASS survey and (ii) some individual E-CLASS items, especially those closely related to specific course learning outcomes.

2. Instructor perspectives on iteration during upper-division optics lab activities

   Although developing proficiency with modeling is a nationally endorsed learning outcome for upper-division undergraduate physics lab courses, no corresponding research-based assessments exist. Our longterm goal is to develop assessments of students' modeling ability that are relevant across multiple upper-division lab contexts. To this end, we interviewed 19 instructors from 16 institutions about optics lab activities that incorporate photodiodes. Interviews focused on how those activities were designed to engage students in some aspects of modeling. We find that, according to many interviewees, iteration is an important aspect of modeling. In addition, interviewees described four distinct types of iteration: revising apparatuses, revising models, revising data-taking procedures, and repeating data collection using existing apparatuses and procedures. We provide examples of each type of iteration, and discuss implications for the development of future modeling assessments.

3. Investigating students' views about the role of writing in physics lab classes

   Writing is an important aspect of experimental physics. Physics laboratory classes typically engage students in scientific documentation and writing in the forms of lab notebooks, reports, or proposals. Instructors of these classes may have a variety of motivations for incorporating writing. We previously developed a framework for thinking about the role of writing in physics lab classes that lists and categorizes possible goals instructors may have for writing. Here, we use that framework as a research tool to investigate students' views about, and experiences with, writing in lab classes, and experimental physics more generally. We present results of an analysis of student responses to weekly reflection questions throughout one semester of an advanced lab class. The results suggest that students think about writing in a variety of ways, and that the context and framing of the course may impact student thinking about the purpose of writing.

4. Student views of what counts as doing physics in the lab

   Numerous studies have identified gender inequity in how students divide roles in lab courses. Few studies, however, have probed how these inequities impact women's experimental physics identity development. In this work, we used closed-response surveys to investigate which lab tasks students view as part of "doing physics" and how these designations varied by gender. In both courses, we found that most students viewed working with the experimental apparatus, taking lab notes, doing data analysis, and thinking about the physics theory behind the experiment as part of doing physics. Only 50% of students, however, viewed managing the group progress as part of doing physics. While men and women's views did not vary in the first-semester lab course, in the third-semester course women were more likely to view notes and managing as part of doing physics than were men. Given that previous research has indicated that women are more likely to take on managing and note-taking roles than men, our results suggest that women may be receiving less recognition as physicists from their peers, which may hinder their experimental physics identity development.

5. Work-in-Progress: Seizing failure as an opportunity to learn: Undergraduate engineering students’ conceptions of failure and iteration

   Atwood, Sara A; Scalaro, Kelsey; Holcombe, Rebecca (June 2024, American Society of Engineering Education Annual Conference)

   The purpose of this work-in-progress research paper is to explore how mid-program engineering students perceive mastery-based assessment in a multidisciplinary, project-based engineering program. There have been calls in engineering education to support students beyond learning specific competencies but to also include curricular practices that help students see themselves as people who can do engineering. While it is understood that students’ mindsets and feelings of control over their own actions and outcomes are influential in how students see themselves as engineers, less is known about what specific classroom practices have this effect. Specifically, students experience assessment in relation to their learning throughout their engineering programs, but little is known about how their perceptions of these experiences impact their sense of agency or control over how and what they learn. This work explores how mastery-based learning and its associated assessment can be paired with a multidisciplinary project-based learning approach to influence students’ feelings of control and choice in their own engineering education. This paper focuses on qualitative findings from an initial pilot study for a larger, NSF-funded project at a small, Eastern private college. This exploratory pilot study includes the perceptions of four second-year engineering students enrolled in an undergraduate engineering program designed around integrated, multidisciplinary projects. A semi-structured interview with multiple open-ended questions was used to prompt participants to share their experiences with assessment in relation to their own learning, performance, confidence, and choices. Directed content and thematic analysis were used to identify codes and develop themes in relation to how participants described certain features of assessment in their engineering program. Preliminary results will illustrate students’ beliefs, learning, and perceptions of choice in relation to specific features of mastery-based assessment in a multidisciplinary project-based context. The initial themes and patterns identified in this preliminary pilot study will be used to set up a more focused secondary full data collection phase in the larger study and to initiate important conversation around the impacts of specific pedagogical choices on outcomes parallel to learning. By better understanding students’ perceptions of this pedagogical design, future classroom practices can be designed and oriented to support students in feeling agentic in their own engineering education and in becoming their version of an engineer.
