Analyzing critical thinking skills using online discussion forums and CCTST

This research study examined the progress of critical thinking (CT) skills in a first year mathematics unit for two batches of students. Problem solving sessions in engineering mathematics were activated through two online Discussion Forums (DFs) and the student postings analysed for CT skills. Changes in participants' general CT Skills were investigated using the California Critical Thinking Skills Test (CCTST) instrument, before and after participation in the DFs. The CT skills identified through the postings from the DFs showed slight improvement over the semester. The general CT skills, as measured by the CCTST showed a progress in the total and the component scores. The study proved that online technology could facilitate development of CT skills in a slow yet steady manner, under the efficient supervision of the instructor
