On-line quizzes and exercises allow students to become familiar with new concepts at their own pace, and can help them learn to summarize and pull ideas together. By providing immediate access to distributed information sources, the instructor has a new tool with which to foster student curiosity. Students with different learning styles can discover information in varied formats, at their own pace, or be inspired to return to traditional, printed sources of information. You can give them access to things that would be impractical in any other medium. This can enable the instructor to help struggling students and to gain valuable feedback.
Students can take multiple choice and short answer tests online.
