WebCT Vista, the successor to WebCT CE, opened for students on September 1. This is the first phase of the transition that will see all courses migrated to WebCT Vista by May 2006. In the Fall 2005 term, WebCT Vista is being used by 85 instructors in 107 courses, with a total enrolment of approximately 8,300 students. The most significant changes are behind the scenes. The backend architecture has been completely redesigned to be more robust and stable under heavy use. An extensive support structure is available for instructors, including just in time email and phone support, online tutorials and structured hands-on workshops. Professors can sign up to use Vista and obtain further details and services on the WebCT at McGill site.
