In this article, I argue that mainstream physics epistemologies and physics teaching and learning practices reify ableism, augmenting the marginalization of disabled and chronically ill people in physics. I make this claim from my standpoint as a physicist who became disabled and chronically ill when I was 2 years old. 

Physics teachers’ definitions of equity inform how they identify inequity and take action to transform it. In this paper, we adapted Gutiérrez’s equity framework from mathematics education research to physics education research. The framework defines equity in terms of four dimensions: access , achievement , identity , and power . We used this equity framework to characterize the equity conceptions shared by 23 teachers who participated in an equity-focused professional development. We found that the access and achievement dimensions of equity are popular with teachers compared to the identity and power dimensions, and that teachers share a common understanding of conceptions of access and achievement in ways that is consistent with educational literature and discourses. 

Energy is one of the fundamental topics taught in high school physics. However, energy continues to betaught as an abstract concept that removes itself from the social implications energy systems have onsociety, in particular toward Indigenous communities. Given the importance of integrating discussionsaround equity into our science courses, in this study we propose a way in which energy justice can beredefined and included in physics classrooms. Redefining energy justice into physics classrooms allows usto connect energy justice to existing energy physics curriculum and lessons plans. In Summer 2020, 22physics teachers participated in a professional development that centered on discussions around energyand equity. We analyzed and coded teachers’ dialogues and conversations around energy and equity toidentify energy justice pillars. The energy justice pillars we identified formed the basis of an energy justiceframework that redefines energy justice for physics classrooms. This energy justice framework allows usto bridge the separation between physics and social justice, as they continue to be viewed as two separateschools of thought in the field of physics. 

Resources-oriented instruction in physics treats student thinking as sensible and then seeks to connect what students are saying and doing to physics content and practices. This paper uses an illustrative case to make progress toward answering the instructional questions: “What does resources-oriented instruction in physics look like?” and “How can I do it?”. We analyze an interaction between a university TA and a group of four introductory physics students completing a worksheet about mechanical wave propagation. We show some of the ways in which the TA's instructional moves supported students in making conceptual progress, even though several of the students' ideas would not be accepted as correct by many physicists. 

Perhaps the most commonly cited student idea about forces in the literature is the notion of an impetus force, defined as the “belief that there is a force inside a moving object that keeps it going and causes it to have some speed,” that can then “fade away as the object moves along.” According to the literature, even after physics instruction students use impetus force reasoning to argue that forces are necessary to sustain motion or that motion implies force. For example, many students drew an upward arrow to indicate a force on a coin that was moving upward after being tossed. The coin was halfway between the point of its release and its turnaround point. Interviews with students in the course indicate that the arrow was meant to indicate “the ‘force of the throw,’ the ‘upward original force,’” and so on. Clement interprets these results to mean that students “believe that continuing motion implies the presence of a continuing force in the same direction, as a necessary cause of the motion.” 

With the ongoing antiracism movement in the United States, there is a call for physics teachers to incorporate equity-based and antiracist activities and curricula into their classrooms. In an online summer professional development course for high school physics teachers, we listened to participants define and compare antiracism and equity. We identified three framings (dual, part-whole, and developmental) that characterize these high school physics teachers' conceptions of the relationship between equity and antiracism. The framings offer insights into physics teachers' notions of anti-racist practice in relation to equity and their concerns regarding enacting equity and antiracism in teaching practice.
