In a three-year ethnographic study of a selective U.S. liberal arts college, it was found that educational development efforts contributed not only to changes in teaching but also to cross-college collaboration and the development of a sense of community. In the 1990s and early 2000s, the college created a learning centre and new educational development activities that spoke to faculty members' needs and college interests. Following these changes, increased collegiality could be seen in collaborations among college employees, and in the educational development activities themselves, resulting in increased interest in educational development. These institutional changes were only made possible because of the college's relatively democratic governance structure, relatively high levels of faculty members' power on campus, and an environment in which ideas and practices could be challenged and re-conceptualised (at least by some employees). Ultimately, this paper argues for more attention to the interrelationships between campus collegiality, teaching and learning, and power in institutions of higher education.
