In this plenary, we model a physics lesson exploring wave and particle properties of light. This teaching exposition exemplifies how queer theory can guide instruction that de-stabilizes binaries, absolutes, and power inequalities within both physics content and classroom social dynamics to promote inclusive, identity-affirming opportunities to learn. Concurrent with the lesson, we narrate our pedagogical reasoning, including how physics education research and queer theory informed the lesson design, as well as how we negotiated constraints (e.g., limited race and gender diversity in physics resources). We conclude by illustrating how instruction in our lesson makes space for complex understandings of science, which expand educational opportunities that affirm queer and trans* students&#39; diverse and dynamic social realities as physics learners.

Leveraging queer epistemic subjectivity to advance justice through physics teaching

PERC 2022 is focused on "queering physics education" through an intersectional lens. By "queering," we are centering queer theory which breaks down social constructions and hierarchies to unpack normalized assumptions. In the context of physics education, we want to apply the theory to unpack who has power in physics to control the production of future physicists, how physics policies and practices are sometimes built on ideas of punishment and power, and how PER embeds binaries in both its content and sociological research. Further, we want to encourage a dialogue that is both a critique and an imagining of a queer future for PER.

Explicit attention will be given to constructions of race, (dis)ability, gender, sexuality and how they interact and impact lived experiences.

We have had such a fun time organizing this year’s PERC. You might be aware that we were committed to transparency and documenting our processes and decision making which we outlined here. This year has also been challenging to be a queer or otherwise marginalized person in the US. And we continue to seek and provide support for those individuals.

As such, we recommend that folks visiting Grand Rapids who have the means consider giving to some local organizations who are working to advocate for those impacted by historic and ongoing marginalization and violence.

The need for physicists to work with others outside of the discipline of physics has become more prominent due to the growing necessity of interdisciplinary subjects and careers. While this need exists, there are few opportunities for physics students to gain collaborative experiences and skills. This study looks at how a community of practice formed within an informal physics program that was designed specifically to bring undergraduate physics and graphic design students together to create an aesthetic physics teaching tool. Throughout this 10 week summer project, we collected qualitative data in the form of interviews and written responses from a team of four undergraduate students, observed meetings, and interviewed the project co-developers. These data record the students' and co-developers' experiences as they work together to develop a public engagement project aimed at combining physics with art and design. Using an operationalized Communities of Practice framework to analyze these data, we are able to explore the formation of a Community of Practice and better understand how developing informal physics programs can foster a community of practice environment.

Mid-Study Update from an Online Design-Your-Own Labortory Experiment Curriculum

The physics teachers require, in addition to knowledge of the discipline, to develop skills that allow them to plan and implement teaching strategies that help students acquire knowledge of the different branches of physics and their usefulness in different contexts. Thus, teacher training plays a fundamental role and can be approached from two perspectives: initial training (profile) and in-service training (teacher training). In Latin America, particularly in Chile and Mexico, the training of physics teachers focuses on their professional profile, so it is necessary to deepen teacher training, so that an ideal profile is achieved to teach physics classes. In general, the teaching training of teachers can again be divided into two: 1) courses on the didactics of physics; and 2) Courses on the educational model of the school. In this work, a study is made about the training of the physics teacher, creating indicators to know the ideal profile of the teacher and proposing training tools that allow the teacher to approach the ideal profile, making a comparison of the results of the study between teachers of Chile and Mexico.

Conceptual inquiry-based introductory physics labs deploy PER-informed pedagogical strategies in physics labs with the aim of helping to improve students' understanding of physics concepts. Unlike traditional labs (which tend to be highly-structured and focus on verification of scientific relationships via precision measurements) and skills-based labs (which tend to eschew the aim of helping students learn physics concepts in favor of teaching experimental skills), some studies have suggested that conceptual inquiry-based labs may have a positive impact on student conceptual understanding, as measured by concept inventories. This paper reports on a randomized controlled study that compares student conceptual gains in electricity and magnetism between a conceptual inquiry-based lab and a skills-based lab. Following a difference-in-differences analytical strategy and hierarchical linear modeling, the result from this study is that the conceptual inquiry-based lab provides no additional benefit to students' conceptual learning gains compared with the skills-based lab. Studies such as these may help physics departments make decisions about the goals and scope of transformations to their introductory lab courses.

Measuring the impact of conceptual inquiry-based labs

How do we engage students with the skills of doing physics? Many reforms have been devised over the years, and one that ties many of these threads together is the framework of Three-Dimensional Learning (3DL). This framework provides a tools for aligning teaching around the 3 Dimensions of how scientists organize their disciplinary understanding. Implementing 3DL focuses on strengthening 'what' we teach, as opposed to active learning techniques that focus on 'how' we teach. Nevertheless, they create learning environments that are meaningfully active and allow students to put their knowledge to use. In this talk, I will present results from exam assessment items and in-class instructional segments, collected over 4 years from introductory courses. Our results indicate that using 3DL-aligned instruction to focus on what is taught is not only productive for student learning, but also offers opportunities for making classrooms active. We also find that Scientific Practices – the dimension encompassing the activities that scientists engage in – stand out amongst the 3 Dimensions: focusing on them leads to the most success in achieving 3 Dimensionality. This makes Scientific Practices the key to creating meaningfully active learning environments where students can put their knowledge to use and learn physics in scientifically authentic ways.

Creating Learning Environments Where Students Can Put their Knowledge to Use

Instructors new to active learning classrooms frequently ask how they should best structure groups in the classroom to ensure optimum learning. Groups within classrooms are complex social systems with many variables, so unfortunately there is no easy answer. Existing group-formation algorithms do not specify how groups should be structured; they only provide a way for instructors to specify their own algorithm based on factors like GPA or Gender. There are many dimensions of student thinking, motivation, and experience that may be relevant, but here we focus on one measurement that is relatively easy to measure: prior preparation. There have been some studies investigating the role of preparation in cooperative grouping, but each study seems to come to a different conclusion. Here we provide some evidence as to why that might be the case by investigating outcomes based on different measures of preparation and investigating the effects of cooperative grouping for different groups of students. We find that groups that are heterogeneous with respect to physics preparation tend to perform better. Additionally, we find that this effect is particularly pronounced for women and underrepresented students, but not for white men. This would seem to suggest that a reason for disagreements in the literature could be sensitive to how preparation is measured as well as the demographics of the study population.

Investigating the role of student preparation on cooperative grouping in an active learning classroom

In this study, we adapted a prior identity framework to investigate how students' perception of the inclusiveness of the 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 inclusiveness 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.

As physics educators integrate computational activities, they must attend to the overarching processes that students follow when interacting with computer code. We describe one such process, Coding Expediently, as an epistemic game that students might play with a goal of minimizing the amount of time or keystrokes required to carry out a set of programming steps. Playing this game reduces the time and cognitive load students devote to step-by-step interaction with computer code, leaving more time and cognitive load for bigger-picture sense-making. We describe observations of two students playing this game during think-aloud interviews in which they completed an introductory Python tutorial. These students represent two differing technical backgrounds: rich experience with mathematics and no programming experience, and moderate experience with mathematics and rich programming experience outside of Python. We describe observations of these students playing this epistemic game selectively (even when they are aware of its benefits) and how they play this game in significantly different ways.

We present a citizen science campaign, Dark Energy Explorers, aiming to improve the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). HETDEX will collect at least one million galaxies that are 9 - 11 billion light-years away, yielding one of the largest maps of the universe. We created Dark Energy Explorers on Zooniverse, the world's largest citizen science platform to help us classify these astronomical objects. With Dark Energy Explorers we train participants, of any background, to be able to distinguish different galaxies by swiping left or right on their smartphone. Initial analysis has shown that citizen science is an efficient and effective tool for classification most accurately done by the human eye. Since launching in late February 2021, we have reached 3.5 million classifications by 8,000 volunteers in 80 countries! Dark Energy Explorers has proven to be a uniquely powerful tool for science advancement and increasing accessibility to science worldwide.

The competencies required of physics-oriented STEM professionals are rapidly evolving to include computational practices (the use of computers to study physical systems). Developing these practices in students requires sustained learning experiences, and high school students benefit from encountering this domain at an appropriate level. However, many high school physics teachers have had limited (if any) exposure to computation, let alone practice with integrating it in a high school-appropriate manner. Our interdisciplinary team of university STEM educators designed and facilitated two semesters of an online professional development sequence for high school teachers. This sequence included asynchronous modules and monthly remote meetings centered around teachers reflecting on their experiences as learners and adaptations to these modules for delivery in their classrooms. At the end of spring 2022, we conducted semi-structured interviews to explore the teachers' experiences and plans for implementation. When analyzing the transcripts from the remote meetings and interviews, we attended to how the teachers operated within two frames. Their learner frame focuses on what the teacher is learning about computation, what piques their own curiosity and interest, and what they feel they can accomplish. Their mediator frame focuses on what they believe their students could reasonably accomplish with computation, what their students are curious about, and how they can use computation to develop their ideal classroom environment. Our analysis highlights teachers' enthusiasm about how computation can contribute to the playful, creative environment that they value in their classrooms. They also saw curiosity as a necessity for productive computational integration and that computation could engage students' curiosity in new ways. We offer implications for future iterations of professional development to emphasize computation's potential to inspire curiosity in all students.
