. . . I am only suggesting that you need to be careful to
give force some sort of unexamined primacy. Given
that, you could start with energy...you just have to
work out the pedagogy, which I think has been done.
What would be extremely useful, to those who teach introductory physics
courses, to have a textbook in which material is organized along the
100% energy-first basis. Writing such a textbook would be a very
demanding task. An organizational outline of topics and subtopics, in
the order in which they should be introduced to students, would also
be useful. Composing such outline is likely to appeal to many
experienced physics teachers, especially those who are retired.
Unfortunately, I am already committed to a very demanding task. But I
would be willing to cooperate if somebody wanted to lead the project.
By the way, I have an idle discussion list, like Phys-L, that can be
turned into a convenient way to work together. That list is private; I
would have to subscribe you (but anybody is able to unsubscribe at any
time). Please write to me in private, if you are interested. On the
other hand, the project might not be necessary if energy-first
textbooks are already in existence. Let me say that I first heard about
the energy-first approach at the Second Modeling Workshop. Perhaps they
already have what is needed. This list is ideal for sharing what you
know and think about energy-first approaches. My private list would be
useful for other things.
