Student issues with both understanding electrical potential and difficulties with interpreting diagrams have been well explored. A prior study showed equipotential diagram modifications of line thickness and color significantly increased student gaze times at the diagrams without increasing students&#39; correctness. Students&#39; awareness and understanding of electric charge sign and its role in electric potential is a major issue. An investigation of modifying traditional equipotential diagrams based on theories of visual affordances to improve students&#39; recognition of electric change sign when ranking electric potential was undertaken. In this study different modifications of color and line style were made to equipotential lines to increase visual salience of charge sign. Students were randomly assigned to traditional or modified diagrams and asked to compare electric potentials for indicated points on given diagrams. Pre- and posttest comparisons and the results of student interviews are presented to clarify the specific issues students have reading equipotential diagrams.

Join us in exploring emergent themes in PER as a scholarly endeavor and as a research community!  Since its inception, PER has served as a confluence of discipline, theory, research methodology, practice, and application.  How have these facets and the interplays among them been fruitful for physics education globally, regionally, locally, or otherwise?  And, how have our successes and interactions influenced the very nature of PER itself?
Following the lead of AAPT for the summer meeting, PERC 20/20 was virtual. Enjoy browsing the content.

Since its inception, PER has served as a confluence of discipline, theory, research methodology, practice, and application.  How have these facets and the interplays among them been fruitful for physics education globally, regionally, locally, or otherwise?  And, how have our successes and interactions influenced the very nature of PER itself?

As part of our effort to develop a concept inventory for statistical mechanics, we have interviewed a number of students who have taken a thermal physics course, at both the undergraduate and graduate level, about their understanding of the statistical mechanics topics taught in the thermal physics curriculum. The questions asked during the interviews were formulated with input from experts in the field, and will later be fleshed out into multiple-choice questions. Here, we report some of our intermediate findings about the students understanding of some of the topics.

Insights into student understanding of statistical mechanics (PERC)

Designing experiments by students is an important scientific skill and increasingly an explicit goal in the creation of new research-based activities. In this work, we studied the use of student design actions in research-based activities. Our definitions of student design tasks are: 1) Describing an experimental procedure invented by the student, 2) Improving a previous experiment, 3) Making hypothesis by students, 4) Choosing questions by students for investigation, and 5) Asking students to design, state, invent, or improve a mathematical or quantitative procedure. We analyzed 66 research-based activities from 11 different design groups to categorize them according to the frequency with which students are asked to complete design tasks

This study will inform the Physics Education Research (PER) community about patterns of partnerships and collaborations between authors and patterns of funding sources for the PER community over the last ten years. The study involves a text-based analysis of all Physics Education Research Conference (PERC) proceedings between 2010 to 2019 to identify funding sources and to determine patterns. PERC proceedings were selected given the central role of PERC to the PER community. PERC proceedings represent the community across scope of projects from small to large, across stage of projects from beginning to finished, and across investigator experience from new to established researchers. Findings are contrasted with those from the Learning Sciences community to provide context for understanding the significance of patterns. The goal of this work is to provide insight into the community's history and ten-year trajectory and thus enable the community to move forward in new and better directions.

The AIP TEAM-UP report identifies the structural and systemic causes explaining why African Americans have not experienced the growth in bachelor's degrees in physics the way they have in other fields or as other minority groups have experienced in physics over the past two decades. Solving these problems requires changing not only the way physicists train students, but how they think about training students. Research on change in higher education suggests the need for physicists and astronomers to recognize and question the norms, values, and culture of their fields. The TEAM-UP report, SEA Change, and the new APS-IDEA all seek to stimulate and sustain a cultural transformation in the profession.
