Previous literature about students' understanding of heat and temperature primarily emphasizes students' misunderstandings of canonical physics concepts. In our study, we used a resources-oriented approach to analyze 653 student responses to questions about thermal phenomena, looking for ways in which their responses could serve as valuable resources for continued learning. We identified three common conceptual resources: (A) heat transfer is directional; (B) an object's physical properties matter in thermal processes; and (C) hotter objects have more energy. These resources could be used to strengthen physics teaching by using students' understandings of heat and temperature to support the development of more advanced physics ideas.
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.
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.
In this paper, we report the preliminary results of an investigation into introductory physics students' conceptual resources for understanding the principle of superposition. We analyzed 368 written responses to a conceptual question that asked students about situations for which the principle of superposition is useful/relevant. We identified four recurring resources related to superposition: (1) localization; (2) independence; (3) quantifiability; and (4) additiveness. Our objective is to support educators by drawing attention to these resources and by suggesting how they can be taken up alongside students to enhance instruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
