N.S. Podolefsky and N.D. Finkelsetein, “Use of analogy in learning physics: The role of representations,” PRST-PER 2, 020101 (2006).…
This is another paper from the open access journal Physical Review Special Topics – Physics Education Research. This paper compares analogies that may be used when teaching about electromagnetic waves.
1. When teaching electromagnetic waves, would you choose to use the sound analogy, string analogy, both analogies, or neither analogy? Why?
2. In general, what analogies have you found to be productive in your teaching? Are there any ways in which you could improve your use of analogies?
