Previous work has shown that many physics students will draw unprompted diagrams while solving physics problems. These diagrams are distinct from prompted student-generated diagrams in that they tend to be smaller and contain fewer details, an unsurprising finding given that these two types of diagrams are generated for different reasons. In this study, we expand and elaborate on reasons physics problem-solvers generate diagrams and the differences between unprompted and prompted diagrams by analyzing a set of 10 interviews with undergraduates, graduates, postdocs, and faculty in physics. Interviewees were given six physics problems and three diagramming tasks to complete, followed by a set of explicit questions about diagramming while problem solving. Participants reported that their unprompted diagrams help them: understand the situation and question; store, organize, and prioritize information; and support solution strategies; and communicate information. Participants also shared their beliefs about the limitations of diagrams, including when they are not useful or stop being useful, and difficulties with generating diagrams.

**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

DBER attracts many faculty from other STEM disciplines, and these faculty have little or no specific training in DBER. DBER requires a mastery of quantitative, qualitative, and/or mixed methodologies, and also a nuanced understanding of breadth of topic, research questions, and theoretical frameworks. This interdisciplinarity is particularly challenging for emerging DBER researchers who often switch into DBER with only discipline specific content and research training. As part of a large study about how STEM faculty become involved with DBER, we interviewed a number of emerging DBER faculty about their pathways into DBER. We conducted a thematic analysis of these interviews grounded in the theoretical frameworks of the reasoned action approach and conjecture mapping. Based on our analysis we identified 3 roles that support new faculty entering DBER. These roles are the peer, the subject matter expert, and the project manager.

Informal physics programs create spaces through various formats to bring together physicists, physics students and public audiences. The facilitators, volunteers, and audience members each bring their own knowledge, experiences, and interests to these spaces which, in addition to availability of resources, influences the physics content and activities that these programs employ. As one part of our greater qualitative research study, we analyze interview data from lead facilitators of multiple informal physics programs with different formats to better understand the key organizational factors important to the design and implementation of meaningful informal physics activities. In this poster, we discuss common aspects from personnel, audiences, and available resources that impact informal physics content and activities, and consider the implications of COVID.

Understanding Influencing Factors of Informal Physics Content and Activities

We present the initial results using an assessment of calculus proficiency in the context of introductory physics (i.e., calculus transfer to physics), comparison of calculus transfer ability with physics self-efficacy, and how these attributes intersect with student gender. Although students demonstrated an improvement in their calculus transfer ability, most nevertheless displayed a decrease in their physics self-efficacy. Similarly, while women showed consistently exhibited lower physics self-efficacy than men, women demonstrated larger gains in their proficiency with calculus transfer to physics. We also discuss future work to better evaluate the interdependence of mathematics self-efficacy, physics self-efficacy, and ability to transfer calculus to physics.

Interplay between physics self-efficacy, calculus transfer ability, and gender

Research on self-efficacy -- or the confidence in one’s capability to perform a task -- has been shown to predict achievement and persistence in the sciences. Throughout a student’s experience in curricular and/or co-curricular activities, they may face threats to their self-efficacy. To investigate the threats or supports to students’ self-efficacy, we are using a mixed methods approach. This novel design creates a holistic narrative of which curricular and/or co-curricular activities are impacting a student’s self-efficacy as well as how and why these activities may be affecting their self-efficacy. We use a mixed methods approach to collect in-the-moment information about lived experiences. Quantitatively, we employ the Experience Sampling Method (ESM) using surveys of domain-specific self-efficacy. Qualitatively, we use daily reflections to investigate threats and supports toward students’ self-efficacy. Using an example, we will present the research design while focusing on building this conversation between the ESM and qualitative reflections.

Identifying Threats and Supports to Self-Efficacy Using Mixed Methods Research

This study is situated within possible selves theory to explore how senior undergraduate students in STEM develop and envision their future possible selves after graduation. We interviewed senior students at an urban institution in the US and encouraged them to think about who they will be in the future associated with their future career choices. This study presents two case studies: Ricky and Francisco. These two students discuss a variety of academic contexts through which they negotiate and explore career-related possible selves: conferences; experiences from classes and research; maintained aspirations for science; and dissatisfaction with education from high school. However, we found that in some cases academic contexts alone are not enough to help students develop possible future selves. Rather, they intersect with social contexts (social identity, out-of-school experiences) through which possible selves emerge. Our findings suggest that students might need more than just classroom-based lessons to explore their possible selves. Implications from this research can benefit the ongoing curriculum development aiming at increasing students' interest in STEM-related careers and building a meaningful professional life after graduation.

In this study, we adapted a prior identity framework to investigate how students’ perception of learning environment (including sense of belonging, peer interaction and perceived recognition) in an introductory physics course predicts their course grades and physics motivational beliefs (including self-efficacy, interest and identity) at the end of this course. We found signatures of inequitable and non-inclusive learning environment in that female students’ mean scores for sense of belonging, peer interaction and perceived recognition were all lower than male students’ in the course. In addition, we found that female students had lower average course grades than male students. Using structural equation modeling, we found that students’ perception of the learning environment predicts their self-efficacy, interest, identity and grades at the end of the course. In particular, students’ perceived recognition, e.g., by instructors and teaching assistants, played a major role in predicting students’ physics identity, and students’ sense of belonging in physics played an important role in explaining the change in students’ physics self-efficacy. Our findings can be helpful for creating an inclusive and equitable learning environment in which all students can excel.

Physics is a degree that supports many career paths, and students often develop preferences for particular methods, such as theoretical, computational or experimental. However, it is not well understood how those preferences develop and affect students' later career decisions. We used Social Cognitive Career Theory (SCCT) as the basis for interpreting students' decision-making processes. SCCT provides a framework for connecting learning experiences, self-efficacy, and outcome expectations with students' interests, goals, and decisions. Semi-structured interviews with 8 physics students were conducted. This analysis focuses primarily on a single student to provide space to explore all three method specializations (theory, computation, and experiment) in more depth. We find that the availability of resources and learning opportunities had a significant impact on students' career choices. Theoretical and computational experiences were readily available through classwork, undergraduate research, and could be worked on at home and in peer study groups. Students lacked the ability to work on experimental physics outside of infrequent classroom opportunities and could not build peer networks that supported their experimental skill growth, which was linked to lower interest and self-efficacy in regards to experimental physics.

Access to opportunities affects physics majors interest and choice of methods specialization

Theory on teacher-student relationship development in higher education is scarce despite the empirical work linking positive relationships to important student outcomes. To advance research in this area, this study explores using Epistemic Network Analysis, a technique that characterizes patterns in data by visualizing them as connected graphs, to characterize patterns in social behaviors exhibited by Teaching Assistants in a large-enrollment algebra-based physics course for non-majors. We recorded classroom interactions between teaching assistants and students in synchronous remote active-learning problem-solving sessions and coded the interactions for the types of social behaviors exhibited by the Teaching Assistants (e.g., addressing students by name or empathizing with student difficulties) as they engage groups of 2-3 students in breakout rooms. Using a validated survey measuring a construct related to teacher-student relationship quality, we identified the two instructors with the highest-rated and lowest-rated scores and compared the connected graphs describing the patterns in their social practices. We present the graphs and generate hypotheses about which social behaviors may contribute most to building or damaging relationships between Teaching Assistants and students. Our results can guide future research in Teaching Assistant-student relationships in physics classrooms and have implications for training Teaching Assistants to build rapport with students.

Characterizing social behavior patterns in teaching assistant interactions with students

In this project, we sought to uncover the cognitive processes and skills that are involved in completing a theoretical physics project. Theoretical physics is often portrayed as a field requiring individual genius and can seem inaccessible to undergraduate students, as well as the public. We drew upon the foundations of Cognitive Task Analysis and completed semi-structured interviews with eleven theoretical physics faculty members from several different research institutions who specialized in subfields including quantum optics, biophysics, computational astrophysics, and string theory. We analyzed the processes and skills of these physicists, focusing on an analysis of idea origin, collaboration, and motivation. We used concept maps to organize these codes and portray the factors that influence the creation of project ideas. We found that motivation and collaboration are fundamental determinants of project ideas and their origins, which contradicts the “lone genius” stereotype. These findings on cognitive processes and skills can help us understand how to better prepare students to do theoretical physics research. Finally, the information gathered during this project may be useful for improving the public understanding of theoretical physics, dispelling the belief that the field requires “genius,” and making it accessible to more students.

Ethical training for scientists is not effective in improving scientists' ethical reasoning. In this study, we had fourteen scientists from several disciplines participate in a fellowship designed to have the participants discuss the roles both scientific and non-scientific values play in science. We conducted pre- and post-interviews with the participants about how they viewed ethics in their research and what they thought the appropriate action would be in vignettes posing ethical dilemmas about research conduct. We analyzed these interviews by focusing on the goals and values the faculty express in their ethical reasoning. Our results show that the values scientists' invoke did change when talking about ethics in their own research, but did not change when looking at vignettes. We discuss the implications of this finding for future work regarding the reason for these shifts in reasoning.
