Universities worldwide offer web-based courses distributed by virtual learning environments (VLEs). A common theoretical framework for implementing VLEs is the pedagogical perspective of instructional design. In this paper, three perspectives of implementation from information systems implementation research and organization theory are presented: implementation as technology acceptance, implementation as diffusion of innovations and implementation as a learning process. These perspectives focus on the VLE as an information system within an organization, the university. The models reviewed offer an important complementary perspective to the pedagogical view of instructional design. The three implementation perspectives are compared and a conclusion is made concerning their implications of successful use and implementation of VLEs.
