Set guidelines for student contributions so that students know whether their contributions meet the evaluation criteria you will use. When setting guidelines, consider the frequency and quality of students’ posts. How many times are students expected to add information to a discussion topic? How long should each message be? Requiring students to make each post a minimum of three sentences will force them to contribute new information to a topic rather than just complementing and agreeing with a previous student.
The frequency with which students post will depend on the topic and on the number of students participating in the discussion. Topics that have one factual answer may limit the number of responses because students may feel that the topic was fully discussed in the first few posts. Even when discussing topics with multiple answers, students may have difficulty providing a unique answer if the pool of students allowed to participate is large. With a large class, consider dividing students into discussion board groups.
Should students observe conventional grammar and spelling rules? If students are not required to follow these rules, be explicit about what is allowed – colloquialisms, slang, text messaging abbreviations, and/or misspellings in proper grammatical context. For example, you might state in the guidelines, “There will be no point deduction for occasional misspelling; however, text messaging or other undefined abbreviations will decrease your grade by 2 points.”
What sources are students allowed to reference in their posts? Will you allow students to reference websites, newspapers, textbooks, or journal articles? The discussion topic and educational objective will influence your decision as to which references are appropriate.
In guidelines for student contributions, also indicate whether students can expect responses from the instructor. How will students receive feedback to know that the group discussion remains on topic and that the discussion has fully covered the information? You might state that “The instructor will monitor the discussion board and post questions to redirect discussion if the thread strays from the main topic.” How will individual students receive comments about their own performance? You may choose to email individual students with comments about their posts. Alternatively, you might identify outstanding posts that other students should use as models.
