| 2007-11-12 | No pain, no gain! It is always a delight to receive an email like the following (from Dai Liang, who is current on exchange at UC Berkeley). Aside from his appreciation of my teaching, I am glad that he pointed out the "mistake" I made in an introductory Microeconomics course. He is right that I did not try to distinguish between Marshallian Demand and Hicksian Demand, although I was well aware of the diffference, and their implication in making welfare calculations. Teachers does not teach concepts in the most vigorous way all the time. The discussion of a concept is usually loose in its first introduction. The discussions become more Vigorous only when the concepts are re-visited. In these later discussions, concepts are further refined.
This is the way we learn and teach. A concepts is introduced, re-visited, refined over and over again. The learning of the more difficult concepts today builds on what we had learned yesterday. Knowing that what we learn today will affect how much we can learn tomorrow, shouldn't we work very hard today?
