Has anybody recently looked at the last two chapters of
Arnold Arons _Teaching Introductory Physics_ (1996)?
IMHO it has problems.
Chapters III-3 and III-4 are a long discussion of thermodynamics ---
mentioning heat, sensible heat, latent heat, caloric, friction, and
energy --- without ever mentioning entropy. Ideas such as spontaneity
and irreversibility that are intimately connected with entropy are
almost-explicitly attributed to energy instead. Also the student is
led by detailed historical arguments (*) to a wrong theory, namely
conservation of caloric. This will have to be unlearned later.
Unlearning is never easy.
(*) Tangential remark: this is yet another illustration of why
IMHO it is a bad idea to follow the "historical approach".
The discussion of friction in section 4,22 seems like wrong physics
and bad pedagogy. Including unobservable microscopic effects in W
largely defeats the purpose of thermodynamics. (I can explain in
more detail if anybody is interested.)
