This study was conducted to determine the effects of non-face-to-face classes using an online forum on student self-directed learning, communication, and problem-solving abilities, and to explore student perceptions of the classes. To this end, pre and post tests were conducted for students in 20 classes that used the N portal-based online forum in the first semester of 2021 at S University, and student perceptions of the classes were collected through open-ended questions. A total of 261 students participated. The results of the effects analysis showed that all three abilities were significantly improved. In addition, through the student perception analysis using the CIPP evaluation model, implications for the context(C), input (I), process (P), and product (P) evaluation categories were drawn to improve classes using an online forum. The results of the study suggest that online forums have educational value as a venue for online learning that effectively facilitates teaching, cognitive, and social presences, and that a systematic approach and the concerted efforts of universities and instructors are needed to improve classes.
