Conceptual metaphors for energy
We find it very useful to use a substance metaphor for energy, in which objects are containers, and energy is in the containers. This metaphor supports ideas of conservation, flow, transfer, storage, etc, which are among our primary learning goals.

Forms of energy
Another primary learning goal is to coordinate our theoretical model of energy with observable properties of objects. One way we do this is by categorizing energy into forms that correspond to types of observable evidence of energy.

Energy conservation in physics and in society
Energy conservation is central both in a sociopolitical sense and in the formal study of physics, but the term has a different meaning in each context. In physics, energy conservation refers to the idea that the same total quantity of energy is always present in any closed system; energy is neither created nor destroyed. In the pubic consciousness, however, energy conservation refers to the idea that we have to guard against energy being wasted or used up; the energy available to serve human purposes is both created (in power plants) and destroyed (in processes that render it unavailable to us). We are creating a conceptual model for what happens to energy during physical processes, expecting to eventually include entropy and the second law of thermodynamics.

Representations of energy
The Energy Project developed has developed special representations that we call "Energy Tracking Representations," because they support learners in conserving and tracking energy as it flows from object to object and changes form. Such representations enable detailed modeling of energy dynamics in complex physical processes.

Embodied learning activities
An Embodied Learning Activity (ELA) is when instructors deliberately arrange for human bodies or parts of the body to stand for entities in the description or explanation of a phenomenon. ELAs are intended to promote and externalize conceptual understanding in physics for the benefit of the learner, the instructor and the researcher. An ELA we call "Energy Theater" plays a central role in Energy Project instruction.

Assessing responsive teaching
We are formulating a framework for assessing the extent to which teachers respond to the disciplinary substance of student ideas as they arise during classroom instruction.

Assessing aspects of the nature of science
We would like to measure growth in teachers' perceptions of science as flexible and constructed, as well as growth in their perceptions of themselves as participants in the scientific community.

We seek to understand explicit and implicit similarities and differences between research paradigms in PER.
