This paper will find out a way to evaluate the discussion board. The variable are thread, location of message within thread, author (student vs. educator), subject line clarity, time of posting, response time from previous message, number of times message was read, number of words, primary purpose, message quality, difficulty level of topic, knowledge level, processing level and use of external resources. I think the hardest part is how the student find the information they want if someone had asked before. And the purpose of the discussion board should be concerned. Not only for education, but also some technology, news discussion board which may cause other variable to show up. The participants are form different career have diversity of purpose. It remains more topics for research.
