Approximation materials	Caltech order-of-magnitude-physics course materials from 1995 and 1997 (syllabi, problem and solution sets, exams, handouts) Examples of how to teach approximation Dissertation (US letter format) including one-half of a textbook on order-of-magnitude physics. The draft textbook is also available on its own. The MIT IAP course page has a more recent version.
Science/math education	Classic report on mathematics teaching by Louis Benezet, about an experiment done 70 years ago in Manchester, New Hampshire. My papers on history of science and science teaching for the 2001 IHPST conference in Denver, Colorado. My observations on teaching first-year physics. Teaching survey: A study of physics teaching in Cambridge physics department.
Computer Othello	BILL: An Othello program released under the GPL. About 210KB. It was once one of the strongest Othello players in the world (but now far surpassed!).
Other teaching materials	At Corpus Christi College, Cambridge. Teaching material used for IA (first-year) physics. Notes on relativity (spacetime diagrams) are here.
