We surveyed educators and college students on their perceptions of a set of physics simulations with and without non-speech auditory display. In this work, we analyzed responses to a single open-ended text prompt from the surveys and found themes related to multimodality and inclusion. In their consideration of the auditory display, some educators and students noted the complementary interplay of the auditory and visual displays, while others noted that the auditory display can serve to augment the primary modality of the visual display. Educators also identified specific groups of learners that could potentially benefit or be negatively impacted by the auditory display, including older learners, younger learners, those with certain &quot;learning styles&quot;, and learners with sensory disabilities. This work is part of a larger effort to expand the auditory display of physics simulations to advance inclusive learning tools, and to investigate educator and student use and perceptions of multimodal physics simulations.

**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

Students in a spins-first course often have difficulties transitioning from discrete to continuous quantum systems. We believe that computation may naturally support the transition because continuous structures like wavefunctions are necessarily discretized in order to be used in operations like numerical integration. We remotely interviewed six students who were concurrently enrolled in a junior-level introductory spins-first quantum mechanics course and a computational lab course, which were designed to synergize with each other. During the interview, participants organized a set of 20 cards that contained a variety of quantum mechanics concepts and representations, including snippets of Python code. Using a phenomenographic approach, this poster will discuss the various ways that participants made sense of the cards and how they organized the cards into groups such as “discrete” and “continuous”.

Inquiry-based physics labs often include a focus on collecting and analyzing scientific data. During the process of making sense of the data, students often engage in data cleaning, even if not explicitly instructed to. Data cleaning is the process of identifying and mitigating instances in the data that are misaligned with expectations or hypotheses of the experiment, often due to equipment or software bugs. Our research analyzes think-aloud interviews from thirteen students and observational data in a first-semester, undergraduate IPLS lab. Qualitative coding focused on students’ decision-making processes while engaging in data cleaning in a think-aloud interview setting and in observation data of students working in the lab. Results show that students typically follow a process of noticing an anomaly, reasoning about its cause, and then either keeping or discarding the anomaly. However, nuances in this pattern differed in the lab environment as teaching and learning assistants had a significant impact on students’ methods of data cleaning. Although determining the source of outliers in data is complicated, unpacking students’ decision-making process is important for lab instructors to better support students in learning how to work with and interpret data.

Investigating Students' Process of Data Cleaning

The concept of infinity is applied widely in various contexts in physics, particularly while implementing the limits of large quantities, such as distance, time, and mass. We are investigating how students deal with this concept when they solve problems in mathematics and physics. We report results from individual semi-structured interviews with physics students, where they are required to use the concept of infinity to solve the problems. We found that students have several difficulties with the implementation and interpretation of the concept of infinity. These difficulties are due to either insufficient understanding of the underlying mathematical concept, differences in how it is interpreted and implemented in mathematics and physics, or inappropriate implementation to physics. We also found that student difficulties stem from the fact that in mathematics infinity is used as an abstract upper bound, whereas in physics it is used to quantify scales of physical quantities.

PhysPort (www.physport.org) is a website that supports physics instructors in incorporating research-based teaching practices in their classrooms. The PhysPort Data Explorer is an online tool for physics instructors to analyze their research-based assessment data (including FCI, FMCE, BEMA, CSEM, CLASS, MPEX, and many more). Instructors upload their students' responses using our secure interface. The Data Explorer matches their pre/post data, scores it, compares it to national data, and graphs it in an interactive and intuitive manner. Instructors can look at their results over time, break their results down by question or cluster, and make comparisons between courses. Instructors can also upload data related to student demographics, academic record or background, and look at their assessment results based on this information. We present the Data Explorer and discuss equity issues around analysis and interpretation of research-based assessment results, in order to support faculty in using data to reveal and address inequities, to more effectively support minoritized groups of students, and to minimize and eliminate harm.

In this study of a large enrollment introductory physics course, I investigated students' use of free online resources (YouTube, Khan Academy, Chegg) and newly-implemented class resources since the Covid-19 transition to remote learning. In my mixed-methods approach, I surveyed and interviewed students on their perceptions and use of expanded course resources which include: pre-lecture module with introductory videos, quizzes with instructional feedback, tutorial assignment with low-stakes grading parameters, and demonstration videos. Students also engage with weekly activities similar to pre-Covid-19 but adapted to the remote setting, including synchronous remote lectures and active-learning recitations, asynchronous recitation quizzes as exam-like practice, and online homework assignments. The survey data suggest students value the expanded course resources as helpful to their learning, and report little use of solutions sites like Chegg. Despite increased accessibility of virtual meetings, students still do not engage frequently with course office hours or the University Learning Centers.

Addressing Barriers in Introductory Physics: Multiple Modes of Engagement and Feedback

During the crises of spring 2020 - the global pandemic caused by COVID-19, the associated economic crisis, and civil uprising due to racialized violence against Black people - many students continued their education despite numerous challenges. Work went into understanding the limitations of remote instruction to better ensure students' success; and instructors adapted instruction and transformed courses to mitigate the impact of these challenges on student engagement and performance. Much of this work centered access inequities. Access inequity occurs when individual students are not able to engage with remote instruction due to conditions that prevent them from receiving instruction, such as lack of material resources, such as adequate computers and access to reliable internet connection, that are essential to remote instruction or poorly accessible educational materials for students with disabilities. However, environmental inequity, situations where a student may be able to access remote instruction materials but circumstances prevent the student from engaging in the ways that other students can-is less well documented. In these situations, students have access but may not be able to devote attention, engage in discussions, turn on video conferencing, or interact as other students might. In this work, we focus on environmental inequity. Additionally, the voices of students as learners and also members of the educational community were neglected in many efforts to transform education to meet the challenging circumstances of the pandemic. For example, Author 3 indicated that faculty were not listening to students and were in many ways exacerbating the challenges that students were facing during the hardships of the global pandemic. That proclamation was the motivation for this study, which examines the experiences of Learning Assistants as students and instructional peer support, with respect to teaching and learning during a year of overlapping crises.

A Student-Centered Understanding of the Impacts of Environmental Inequities on Teaching and Learning during Remote Instruction

This study investigated gender differences in perceived recognition as a physicist and its relation to physics identity. We surveyed 688 students (228 women, 460 men) at a research-intensive university in [country redacted for review] at both the junior and senior undergraduate levels with items measuring perceived recognition and physics identity. Similar to other studies, we find that female physics students report lower recognition as a physicist from their instructors, families and friends compared to male students. In contrast, there were no gender differences in students’ perceptions of friends asking them for their advice/input in physics related problems. Perceived recognition from instructors was lower than recognition from family and friends for both male and female students. We find that both perceived recognition from instructors and physics identity are significantly lower at the senior compared with the junior levels. Multiple linear regressions for male and female students individually found that both perceived recognition from instructors and from family/friends predicted students’ physics identity. However, the perception that their friends sought their advice on physics-related problems predicted physics identity only for female students, not for male students. These results may indicate a shift in students’ understanding of what it means to be a physicist as they progress through the degree program, and that female students may have a wider range of sources feeding into their physics identity formation. The results point to further research being needed to understand better the mechanism by which students form perceptions of instructors seeing them as physics people.

Gender effects in perceived recognition as a physicist and physics identity

Informal physics programs can play a vital role in supporting student learning and sense of community beyond the formal settings of a classroom or laboratory. This work builds on a recent study of the impact of facilitating informal physics programs on students' physics identity, sense of belonging, and career skills development by narrowing the focus to specifically examine effects on female students who are underrepresented in physics. We found a significant shift in confidence of choice of major when compared prior to and after facilitating informal physics programs. All female students who were interviewed discussed a positive effect of participating in informal programs on their interest and motivation with regards to the field of physics and the development of characteristics indicative of a growth mindset.

Impact of informal physics programs on female university students

Disability is an often-overlooked aspect of diversity. Recent research has indicated that there are barriers to access and participation for disabled students inherent in the design of physics courses. To help counteract these barriers, universities are required to provide reasonable accommodations for disabled students. However, not all students use the accommodations they have access to because of social factors (e.g., disability stigma), and others do not have access to the professional diagnosis often required to access accommodations. The purpose of this study was to explore the experiences of students who identify with a disability/impairment who were taking an emergency remote teaching (ERT) physics course in Fall 2020 to inform policies about providing access to students in future remote and face-to-face courses. In this paper, we present the prevalence and types of impairments disabled students in physics courses reported, their reported accommodation usage, and ethical considerations of this work. Overall, we find that disabled students represent a sizeable group in physics courses, and there are positive and negative reasons students did not use or request accommodations.

Students’ use of disability accommodations in emergency remote teaching

Physics is perceived to have a “culture” of exclusion, which includes not embracing individuals from certain demographics who are underrepresented in the field. Many who are from underrepresented groups have stated they feel impacted by cultural pressures to assimilate to what is traditionally considered a “physics person.” In order to better understand these cultural pressures, this study examines statements from two physics teachers who participated in a summer professional development (PD) workshop. During the summer PD, the two teachers participated in sessions where they made statements that described how physics culture impacted their identity and understanding of equity, which ultimately shaped their approach towards teaching. Analysis of teachers’ statements showed that physics culture impacted the teachers' views on instruction in the areas of inclusivity and shaping students' physics identity. This study has implications for research on the role of physics culture and how it impacts underrepresented students’ and teachers' identity and approach to equity.
