Derek Bok, former president of Harvard University, has some concrete suggestions to improve higher education. His most prominent suggestion is that Ph.D. Candidates should be trained to teach, not just to compete their dissertation.

But the most interesting comment occurs near the end of the article when he writes:

“A more plausible reason for the sluggish pace of reform is the scanty preparation given to graduate students for their role as educators. Lacking such training, newly minted Ph.D.’s naturally begin their teaching by trying to emulate the professors they respected most during their student days. While there is something to be said for this practice, it hardly encourages innovation in the classroom. Rather, it tends to produce an uncritical, conservative attitude toward teaching, quite at variance with the way most faculty members go about their research.

“Continuing this approach is likely to prove even more costly in the future than it has been in the past. President Obama has called for a significant increase in the number of Americans graduating from college by enrolling hundreds of thousands of new students every year. Many of these young people will be less prepared for college work than the average student today and, hence, more difficult to teach.

“Even if colleges manage to meet the president’s goal (and that will be a tall order indeed), America will never regain the huge lead in educational attainment that helped to make it the world’s most prosperous nation from 1870 to 1970. Now that a dozen or more countries have made the transition from an elite to a mass or nearly universal system of higher education, it will be all that we can do simply to keep up.

“If the United States is ever to regain a significant economic advantage from the education of its people, it will have to come through the quality of instruction that our undergraduates receive and not just from the quantity of college degrees being offered. Such instruction will surely be slow to arrive without a faculty trained to bring to its teaching the same ample store of background knowledge, the same respect for relevant data, and the same questioning, innovative spirit that professors have long displayed in carrying out their research.”
