This study aims to investigate the effectiveness of an ICT-based “participation points system (PPS)”, which is used to encourage students’ participation by giving them immediate compensation for their in-class participation. In the treatment-control experiment, an ICT-based PPS tool was used for the treatment group (84 students), and was not used for the control group (51 students) for a semester. A post-survey was conducted to examine the effects of the PPS on students’ perceived participation and affective factors (interest, confidence, attitude, motivation, and anxiety). In the pre- and post-test experiment, pre- and post-surveys were conducted for a group of 77 students to examine the effects of the PPS. Linear regression results indicate that the use of the PPS was highly effective in the affective domains and the perceived degree of participation, especially in interest and confidence. This seems to be due to the encouraging class environment and a team-based scoring system. Thus, according to the current results, the use of the ICT-based PPS is highly recommended as the ICT tools are further integrated into classrooms.
