Learning achieved in structured online debates: levels of learning and types of postings

The purpose of this study was to examine the learning process exhibited in restrained online debates in terms of to what extent each of Bloom's six levels of cognitive learning were exhibited among four types of message (argument, critique, evidence, and explanation). Thirty-three graduate students enrolled in an online entry-level course in distance learning participated in this study. The threaded discussion postings from four structured online debates were analyzed. The results indicated that five of the six levels of cognitive learning (except for knowledge learning) were achieved to a certain extent among the four types of postings. Chi square tests indicated that higher levels of learning were most likely to be exhibited in critique and argument postings. Message-response exchanges ending with critiques or starting with argument messages were most likely to elicit higher levels responses. The results were discussed in light of better understanding of student learning and implications for instructional designs of discussion topics and restraints.
