English classes at SUT were divided into two weekly sessions: a tutorial session and a computer laboratory session. The tutorial session took place in a normal classroom for two periods of fifty minutes, while the computer laboratory session lasted
one period of fifty minutes. In the present study, however, the tryout and experiment were conducted only in the computer laboratory sessions. The participants were assigned to do online activities in Wiki-based Collaborative Reading Lessons (WCR Lessons henceforth) created by the researcher following the course syllabus of English III.
