"This is the first of what I hope will be a long series of posts aimed at providing back-up to first-year Cambridge mathematicians. This may seem a strange thing to do, since the Cambridge system of supervisions (classes taught on a one-to-two basis, usually discussing questions set by lecturers) already provides an excellent back-up to lectures. Do Cambridge undergraduates, who already have closer attention than in any other university I know about, really need even more help?"

"BiwaScheme is a Scheme interpreter written in JavaScript." It seems to be actively developed.

Another essay on teachings of mathematics.

"Let's say, in the near future, tens of millions of students start learning math using online computer software. Our logs fill with a massive new data stream, millions of students doing billions of exercises, as the students work."

"A reading protocol is a set of strategies that a reader must use in order to benefit fully from reading the text. Poetry calls for a different set of strategies than fiction, and fiction a different set than non-fiction. It would be ridiculous to read fiction and ask oneself what is the author's source for the assertion that the hero is blond and tanned; it would be wrong to read non-fiction and not ask such a question. This reading protocol extends to a viewing or listening protocol in art and music. Indeed, much of the introductory course material in literature, music and art is spent teaching these protocols."

"This site is being developed by Dr. Beth Harris and Dr. Steven Zucker as a dynamic enhancement (or even substitute) for the static Western art history textbook. We are looking for contributors—especially for canonical non-Western material and other survey topics we have not yet covered. We welcome comments, feedback and corrections."

"This participatory seminar focuses on the knowledge and skills necessary for teaching science and engineering in higher education. This course is designed for graduate students interested in an academic career, and anyone else interested in teaching. Readings and discussions include: teaching equations for understanding, designing exam and homework questions, incorporating histories of science, creating absorbing lectures, teaching for transfer, the evils of PowerPoint, and planning a course. The subject is appropriate for both novices and those with teaching experience."

Nice writing about teaching (TCS) and his personal experience (good and bad).
