Earning a bachelor&#39;s degree is expensive and time-consuming. Many undergraduate students pursue Advanced Placement (AP) courses in high school or transfer coursework from degree-granting institutions. However, the effect of those transfer credits on the time that it takes students to graduate (time-to-degree) is currently not well understood. We have investigated how incoming transfer credit impacts students&#39; time-to-degree by defining three independent groups of transfer students: (1) those entering with College-level transfer credit, (2) those with only AP-level transfer credit, and (3) those without any transfer credit. The time-to-degree has been shown to be statistically different for each of these groups, with students who enter with college-level transfer credit graduating with the fewest semesters. We have explored differences in time-to-degree for students majoring in Physics and particularly for those who are traditionally underrepresented in the field. Cohen&#39;s d results suggest large negative effects on the time-to-degree for Physics students without any transfer credit, especially for female students and underrepresented ethnic or racial minority students. These results provide implications toward how universities advertise graduation in four years, as well as other impacts toward student financial aid such as four-year scholarships.

**Making Physics More Inclusive and Eliminating Exclusionary Practices in Physics**

As a gateway discipline to STEM majors and careers, physics plays a central role in deciding who does, and who doesn't, get to discover and pursue scientific careers. Technical and scientific professionals are rewarded with economic privilege and status which affords them both social and cultural power. Therefore, social justice will be realized only when the opportunity, and the choice, to excel in physics is open to all students. The culture and practices of the physics classroom reflect the culture of physics at large, which raises the question of how our professional physics communities can embrace, rather than inadvertently repel, a diverse group of academics that can help improve physics culture.  To this end, the 2021 Physics Education Research Conference will focus on defining inclusive spaces and practices. Additionally, we will explore strategies for eliminating exclusionary practices in our classrooms, research spaces, and professional organizations. We call on the community to propose sessions that will drive conversations related to these initiatives throughout PERC 2021.

Making Physics More Inclusive and Eliminating Exclusionary Practices in Physics

Using a completeness (or closure) relation is a neat math trick in quantum theory. Completeness relations capture the fundamental property that a basis set spans a vector space, and conceptually can be thought of as a special form of the identity operator. In quantum mechanics, completeness relations can be used to express a quantum state in a particular basis, change which basis a state is expressed in, as well as mathematically model the effect of a quantum interferometer. We have analyzed students' written responses to homework and final exam questions related to completeness relations from a junior-level, introduction to quantum mechanics course. In this poster, we will present student reasoning and difficulties using completeness relations.

Student Reasoning with Completeness Relations in Quantum Mechanics

An emerging body of research suggests that the nature of human reasoning itself may impact student performance on physics questions. Analysis of student reasoning patterns through the lens of dual-process theories of reasoning (DPToR) indicates that students may struggle to engage analytical processing productively when responding to physics questions containing salient distracting features (SDFs). While students may reason correctly on one question (screening question), they may abandon that same line of reasoning on an analogous question containing an SDF (target question). As part of a larger effort to investigate and support student reasoning in physics, we have designed and tested an intervention that explicitly guides students to apply the reasoning they successfully used on the screening question to the target question in order to help students reconsider their default responses. On this poster, preliminary results will be presented and implications for research-based curriculum development will be discussed.

Supporting Students in Exploring Alternative Lines of Reasoning

Graphs are an important interdisciplinary (and everyday) tool for visualizing and interpreting information use and communication processes and, thus, an essential part of 21st Century Skills. Especially linear functions are a fundamental component of school and university education, but students often have difficulties interpreting this type of function, in mathematics as well as in physics -- especially in kinematics. This paper presents first results of an eye-tracking study, which compares learners' visual attention during the interpretation of linear graphs in mathematical and physical contexts. In this study, gaze data of N=35 xxx (details redacted for review) upper secondary school students were recorded while solving items of a validated test instrument. This instrument consists of pairs of items in the mathematics and kinematics context that are isomorphic to each other, i.e., require the same procedure to solve. The analysis of the eye-tracking data provides information about the cognitive processes involved in solving the different items. On the basis of selected items, it is shown to what extent the gaze behavior differs between mathematical and kinematic contexts in isomorphic item pairs and which conclusions can thus be drawn about the different solution strategies and, thereby, also about difficulties in transferring mathematical procedures into a physical context.

Gaze pattern analysis to reveal student difficulties in interpreting kinematic graphs

Much existing physics education research (PER) on student ideas about momentum focuses on the difficulties that students face when learning this topic. These difficulties are framed as obstacles for students to overcome in order to develop correct understandings of physics. Our research takes a resources-oriented approach to analyzing student responses to momentum questions, viewing student ideas as valuable and potentially productive for learning, over and above their correctness. Here, we highlight four conceptual resources that provide insight into students’ ideas about momentum, which are the conservation resource, direction resource, collisions resource and properties resource These resources are context-dependent and could be elicited and built on by instructors to support students in developing more complex and sophisticated understandings of physics.

Identifying student resources for understanding linear momentum

The research in E&M has commonly focused on problem-solving abilities and the use of physical principles for such matters. Several studies have found that some concepts represent a challenge for undergraduate students, such as Gauss's and Ampere's laws. The inability to identify and analyze the symmetry of field and field source distributions and focus on the surface features of these E&M systems are two of the main difficulties associated with these laws so far. We present this study to contribute with a different perspective of observing 322 introductory E&M students' understanding of these laws with unconventional shapes for the field sources' enclosing objects. We use a phenomenographic approach to detect difficulties and compare the difficulties between the two contexts and those previously reported. Our main findings suggest that some students make an incomplete or incorrect analysis of the situation when they refer to surface features of the situation and that the confusions between flux and field in the electric context, or between circulation and field in the magnetic context, persist. Finally, we present suggestions for teachers to approach these difficulties.

Collaborative group work is an important aspect of many introductory physics labs. This research focuses on how the gender diversity of a group of students impacts their engagement in the collaborative portion of an online introductory physics lab. We conducted a mixed methods study to determine the relationship between the gender composition of groups and the degree of engagement those groups demonstrated in weekly collaborative activity reflections, using randomly-assigned groups of four students. We also investigated the impact of giving students explicit grading rubrics. We conducted a series of semi-structured interviews with students in order to understand their perspective and experiences collaborating with others. When students were not provided with grading rubrics, we found that groups of all men had highest levels of engagement, and groups with only one woman had lowest levels of engagement as evidenced by the length of written reflections. On the other hand, when students were provided with explicit grading rubrics, groups with one or more women had higher, comparable, levels of engagement. In interviews, women described interactions in majority-male groups that were detrimental to effective collaboration, such as being ignored or talked over. These results suggest that instructors could improve equity in online lab courses (and perhaps other classes as well) by assembling student groups that do not have a single, isolated, woman group member or providing clear grading expectations.

Challenges of building an inclusive community of learners in the physics lab

Students as Partners (SaP) is an approach where students and faculty work in partnership on the co-design of a curricular or institutional change effort. Our team implements SaP through Departmental Action Teams (DATs), which are facilitated teams of faculty, students, and staff within a single STEM department working on some issue related to undergraduate education. In our research, we aim to understand the ways in which SaP becomes enacted in DATs. Through analyzing interviews with student and faculty members of a single DAT, we construct a case study of the complexities and challenges of student-faculty partnership. We find that members of a partnership can hold different views of that partnership. Underlying these differences are differing views about their joint work as well as differences in how visible power dynamics are. In self-critically analyzing the ways in which we mitigated and reproduced power dynamics, we then reflect on our project’s areas for growth.

Unpacking Challenges in Student-Faculty Partnerships on Departmental Action Teams

Change efforts in higher education are increasingly focused at the department-level, allowing for the benefits of a grassroots approach while also incorporating top-down implementation. Two models for departmentally-based change are active at the University of Colorado Boulder: the Departmental Action Team (DAT) Project and Teaching Quality Framework (TQF) Initiative. In both models, externally-facilitated teams meet regularly to work on projects relevant to their departments, however the focus of teams’ work differs, as do the models’ underlying frameworks and principles. To better understand how these models of institutional change operate and their implications for change work in higher education, we interviewed individuals from both efforts, including team facilitators, principal investigators, and those involved in the development of the models. Our results indicate that differences between the models (such as facilitation styles, team meeting processes, and team-level and initiative-level goals) have connections to the frameworks underlying each, and they have implications for participants’ experiences and teams’ outcomes. We present notable differences and similarities in the change process in the two models, the potential impact of these similarities and differences, and implications for others doing change work.

Fostering departmental change through collaborative work: an analysis of two approaches and their implications

As the field of Quantum Information Science (QIS) continues to advance, there is an increased need for a quantum-smart workforce to address the needs of the growing quantum industry. As institutions begin to expand their course offerings, there is a unique opportunity for discipline-based education researchers to have an impact on the curricular and pedagogical choices being made in these courses. As a first step, it is necessary for education researchers to have a representative picture of what QIS education currently looks like.

We reviewed recent course catalogues from a large sample of institutions in the United States looking for courses focused on QIS content. Our conservative analysis reveals that roughly a quarter of the institutions we reviewed offer QIS courses. While encouraging for such an emerging field, we found disparities in the types of institutions offering these courses as the vast majority were Doctoral-granting institutions. Additionally, we found that some classifications of minority serving institutions were much less likely to offer a QIS course (for example Historically Black Colleges and Universities or Predominantly Black Institutions), while Asian American and Native American Pacific Islander serving institutions were more likely than the national average to offer a QIS course. These disparities may lead to further racial, socioeconomic, and geographic disparity in the future quantum workforce. We also found that there was no single department that offered a majority of the QIS courses, indicating that the best efforts to improve QIS education will need to consider the multi-disciplinary nature of the field of quantum information science.

An Overview of Quantum Information Science Courses at US Institutions

The growing push to address the lack of diversity in physics has come with an array of curriculum reforms and interventions. There has been work in Physics Education Research (PER) that has supported these reforms, including studying the experiences and identity development of students from minoritized backgrounds. However, there has been a lack of critical reflection on the core methodologies and constructs used in PER. Here, we present a critical analysis of qualitative and quantitative work used to define and measure “expert-like” thinking, beliefs, and practices in physics. We show that this work has largely omitted any consideration of race or cultural backgrounds of participants, instead defining “experts” as either physics faculty or Ph.D. holders. Research in critical theory demonstrates that failing to intentionally address potential biases tends towards reinforcing those biases. Thus, work in PER on expert-like thinking may unintentionally replicate, rather than challenge, existing biased structures in physics. We conclude with recommendations for constructing more inclusive views of what it means for students to develop “expert-like” thinking.
