AFRICAN AMERICAN ADMINISTRATORS' EXPERIENCES IN PREDOMINANTLY WHITE COLLEGES AND UNIVERSITIES

The purpose of this study was to better understand the experiences of African American administrators in predominantly white colleges and universities. In depth interviews were conducted with eight executive level administrators: six presidents and two associate vice chancellors. The interview process used a phenomenological approach focusing on the participants' interpretations and evaluations of their respective administrative careers. The participants were asked questions relative to their experiences which led them to predominantly white colleges and universities, their current administrative positions and responsibilities, and provided advice to African Americans seeking similar administrative positions.

INTERNATIONAL ACADEMIC RELATIONS: SOME REFLECTIONS ON UNIVERSITIES AS CULTURAL INSTITUTIONS IN THE WORLD COMMUNITY

The premise of this article is that international academic relations as a field of study need to be defined and given a theoretical underpinning. The authors therefore analyse various approaches to the study of international relations in general and propose ways by which the particularities of international academic relations might be linked to the larger subject. Of importance here is the development of a framework which will take into account the political‐economic role of the university both as a cultural institution and as a knowledge institution. The framework they suggest is then tested with regard to an examination of the international academic relations of the OECD countries, particularly Canada, with the universities of China.

THE IMPACT OF FORMATIVE AND SUMMATIVE EVALUATION OF TEACHING IN NORTH AMERICAN UNIVERSITIES

This paper reviews recent research evidence on formative (developmental) and summative (judgemental) evaluation of teaching in North American universities. The major conclusions of the review are as follows: (1) student ratings are the most common method of evaluating teaching in North American universities, and their popularity appears to be increasing; (2) student ratings have been found to provide reliable and valid information on limited aspects of teaching competence; (3) teaching evaluations make a difference in decisions on faculty salary, tenure and promotion; (4) evaluation of teaching has been shown to produce modest improvements in teaching effectiveness; (5) faculty satisfaction with teaching evaluation practices ranges from very high to very low, depending on institutional context; and (6) there is consensus that several specific improvements are needed in the current teaching evaluation system.
