Require students to post a minimum number of times to demonstrate that they have visited and revisited the material and conversations over several days. Often times, students go the discussion boards once a week, post a flurry of messages, and then never return to read any responses to their postings. Requiring students to post over several days encourages them to read and respond to the range of responses.
Online discussion boards facilitate student reflection. As such, postings to the discussion boards should demonstrate a thoughtful approach to the content.
Research indicates that when using online discussion boards, students are more likely to cite research and class readings in their responses. Use this to your advantage by calling for the use of supporting evidence in student postings.
