We provide evidence that a learning activity called Energy Theater engages learners with key conceptual issues in the learning of energy, including disambiguating matter flow and energy flow and theorizing mechanisms for energy transformation. A participationist theory of learning, in which learning is indicated by changes in speech and behavior, supports ethnographic analysis of learners' embodied interactions with each other and the material setting. We conduct detailed analysis to build plausible causal links between specific features of Energy Theater and the conceptual engagement that we observe. Disambiguation of matter and energy appears to be promoted especially by the material structure of the Energy Theater environment, in which energy is represented by participants, while objects are represented by areas demarcated by loops of rope. Theorizing mechanisms of energy transformation is promoted especially by Energy Theater's embodied action, which necessitates modeling the time ordering of energy transformations.

When students share and explore chemistry ideas with others, they use gestures and their bodies to perform their understanding. As a publicly visible, spatio−dynamic medium of expression, gestures and the body provide productive resources for imagining the submicroscopic, three-dimensional, and dynamic phenomena of chemistry together. In this paper, we analyze the role of gestures and the body as interactional resources in interactive spaces for collaborative meaning-making in chemistry. With our moment-by-moment analysis of video-recorded interviews, we demonstrate how creating spaces for, attending to, and interacting with students' gestures and bodily performances generate opportunities for learning. Implications for teaching and assessment that are responsive to students' ideas in chemistry are discussed.

For over 30 years, researchers have investigated students' ideas about energy with the intent of reforming instructional practice. In this pursuit, Watts contributed an influential study with his 1983 paper ''Some alternative views of energy'' [Phys. Educ. 18, 213 (1983)]. Watts' ''alternative frameworks'' continue to be used for categorizing students' non-normative ideas about energy. Using a resources framework, we propose an alternate analysis of student responses from Watts' interviews. In our analysis, we show how students' activated resources about energy are disciplinarily productive. We suggest that fostering seeds of scientific understandings in students' ideas about energy may play an important role in their development of scientific literacy.

A perpetual problem learners face is identifying which aspects of embodied experiences are relevant for appreciating the world in culturally specific ways. Vygotsky argued that social interactions with more competent cultural members provide arenas for linking everyday and scientific concepts. However, the precise interactional mechanisms of how these linkages are forged remain underexamined. I argue that understanding these mechanisms requires examining how intersubjectivity is built and maintained. I propose that ethnomethodological conversation analysis and the co-operative action framework provide a uniquely suited analytic orientation for this project because they focus on the fine details of the actual practical methods people use to procedurally achieve intersubjectivity. To illustrate the utility of these approaches, I show how the fine details of multimodal revoicing interactions present semiotic challenges that allow learners to link everyday and scientific concepts. Specifically, I examine the role dialogic gesture plays in reformulating a multimodally expressed idea about what it means to “go faster.”

As technologies that put the body at the center of mathematics learning enter formal and informal learning spaces, we still know little about the teaching methods educators can use to support students' learning with these specialized systems. Drawing on ethnomethodology and conversation analysis (EMCA) and the CoOperative Action framework, we present three multimodal ways that educators can be responsive to learners' embodied ideas and help them transform sensorimotor patterns into mathematically significant perceptions. These techniques include (1) encouraging learners to use gesture to express and reflect on their ideas, (2) presenting multimodal candidate understandings to check comprehension of learners' embodied ideas, and (3) co-constructing multimodally expressed embodied ideas with learners. We demonstrate how these techniques create opportunities for learning and discuss implications for a multimodal, embodied practice of responsive teaching.
