The "block plan," in which students take one course at a time for a few weeks, rather than four or five courses over a semester, is attracting interest in Canada, The Globe and Mail reported. Quest University has adopted the system and three institutions -- Acadia University,  Algoma University and the University of Northern British Columbia -- have started to explore the use of block schedules. Among the small number of institutions in the United States that use the system are Colorado, Cornell (Iowa) and Tusculum Colleges.
