1,000 full-time faculty members at four-year colleges and universities gathered as part of the Faculty Professional Performance Survey administered by Mr. Braxton and two Vanderbilt doctoral students in 1999. That survey had asked the faculty members how often they engaged in each of nearly 70 distinct scholarly activities, such as experimenting with a new teaching method, publishing a critical book review in a journal, or being interviewed on a local television station. All of the faculty members examined in the new analysis were either tenured or tenure-track and fell into one of four academic disciplines: biology, chemistry, history, or sociology.
