This is a case study of faculty adoption and use of Horizon Wimba Virtual Classroom in online courses at a Southeastern University in the United States. The purpose of this case study was to explore faculty adoption and use of Horizon Wimba in their online courses. This inquiry is based on Yen et al. (2010) adoption factors (organizational, social, personal and technological) and the features of the virtual classroom. The research questions are 1) What factors and features influence faculty adoption of the Wimba Virtual Classroom? 2) How do faculty rate the Wimba Virtual Classroom using the characteristics of innovation? 3) How do faculty classify themselves using Roger's model of diffusion of innovation? 4) How do faculty use the Wimba Virtual Classroom in their teaching? Roger's diffusion of innovation was used as the theoretical framework for faculty adoption of virtual classroom. In the Fall of 2010, faculty were surveyed and interviewed about their decision to adopt and use Wimba. This case study provides meaningful information for administrators interested in promoting technology enhanced learning on their campuses and for faculty considering adoption.
