- EXPERIENCE WITH GENERAL EDUCATION
- In 1975, my second year on the Harvard faculty, I taught my first General Education course at Harvard, on the elements of computer science for non-specialist undergradautes. In the subsequent three years I grew that course to nearly five hundred students per year. It has always been my passion to make contemporary research and scholarship accessible and relevant to students of widely varying background and interests. My present general education course, Bits, melds computer and communications science with law and public policy, and is part of Harvard’s program of general education courses in Empirical and Mathematical Reasoning.
- While I was Dean of Harvard College, I was a member of Harvard’s Committee on General Education and was involved in the recruitment, selection, and evaluation of general education courses. I also chaired the College’s subcommittee on Quantitative Reasoning.
- More generally, I have argued in several of my writings that the development of the research university, with its increasingly specialized research faculty, has been a boon for economic progress but problematic for the education of citizens and civic leaders. I argue in several of my writings for a restoration of universities’ sense of social and civic mission.
I blog about developments in the world of digital information and society at bitsbook.com, a site associated with my book Blown to Bits.

I started teaching at Harvard in the fall of 1974, a decade before the university offered an undergraduate degree in Computer Science. I have therefore had the privilege of creating a number of the undergraduate courses in the field, and of teaching introductory computer science and theoretical computer science (especially foundations of computer science and algorithms) to thousands of students in aggregate.
About five years ago I started teaching a general education course on social and legal issues precipitated by the digital revolution.
I also teach a freshman seminar on Amateur Athletics, a study of the social history of sports in America and how it relates to fundamental American notions of fairness and equality and the dynamic of body, mind, and spirit.
Here are a few outside boards of which I am or have been a member.
- Computing Research Board, 1985-1988
- Trustee of the Roxbury Latin School, 1979-present; President of the Trustees, 1992--present
- Trustee of the Charity of Edward Hopkins, 1995-2003
- Steering Committee, Harvard Advocates for ROTC
