3.3.2. Analysis of the influence of participation in online collaborative learning on students’ learning achievement
Students’ participation in online collaborative learning is based on their activity log files. The participation
attributes used in data mining to predict their learning achievement are login frequency (log_), viewing discussions
(disc_v), viewing supporting learning materials (res_v), posting comment during collaboration (post_c) and learning
achievement (achieve_). Students’ log files were analysed using Weka data mining software by applying the C4.5
algorithm to produce a decision tree that shows how online collaborative learning influence students’ achievement
