My education in physics occurred 40 years ago, so the simple article
below on the value of modeling as an instruction technique was new and
of interest to me. I can see where it would be of value in introductory
courses, but have any of you used this technique in advanced
undergraduate/graduate courses on classical mechanics, quantum theory,
relativity, etc. It's great to discover things by yourself, but is
there really time to do this with the great number of advanced topics
which have to be covered, not to mention the practicality of modeling
advanced concepts?
