I heard some good debate on the idea of making an "Energy Concepts
Inventory" something like the FCI (Force Concepts Inventory). The
conclusion seemed to be that the sciences use the term energy in so many
different ways that science needs to sort this out before we can expect
students to clearly articulate these concepts.

1) Is this debate documented anywhere? In particular, is
there something that interested parties could read and
then cite?

2) How many different definitions of /physics/ energy are
we talking about? Is there more than one serious contender?


There was some good discussion at the 2011 AAPT summer meeting in Omaha.
Look for the session:
PER: Student Reasoning II
https://www.aapt.org/Conferences/sm2011/sessionpanel.cfm?type=other&sort=name

I particularly recommend looking for anything Stamatis Vokos wrote on the
subject. His philosophy is quite deep, so I wouldn't pretend to understand
everything he said.

Also from that session Rachel Scherr provided a nice overview of the
discussions of forms of energy given by various state standards. To quote
her abstract: "We offer examples of intuitive ontologies for energy that we
have observed in classroom contexts, including energy as a quasi-material
substance; as a means of activation; as a fuel; and as an ineffable
quantity which is not subject to further analysis. In the classroom,
multiple and overlapping metaphors for energy complement one another in
complex representations of physical phenomena. "
She mentioned standards in several states where they have interesting
acronyms to memorize the forms of energy: SCREAM - Sound, Chemical,
Radiant, Electrical, Atomic, Mechanical
Googling now for other ideas:

Please don't hate me for showing you these. :)
