１）Each of the four journal clubs was led by two faculty members. ２）Recent primary publications relevant to lectures in the previous section were selected by the faculty and posted on the Web. ３）Students were required to answer several questions related to the papers before the discussion forum. ４）During the classroom session, the teachers called on the students to explain the figures and tables in the papers. ５）This was followed by an open discussion of the papers and the posted questions. ６）The teachers then provided individual written critiques of students' written answers, and students revised their answers to respond to the critiques. ７）The revised answers were posted on the Web with anonymity maintained. The students then posted brief comments on two of their peers' answers using their student number as an identifier. ８）For each of the four discussion forums each student received grades for the original answer, the revised answer, and the peer critiques.
