The study was carried out to determine the effects of the mind mapping method in web-based courses on students' metacognitive learning strategies and self-regulated learning skills and to determine the students' views on this. The study findings showed that there was a significant difference between the pre-test and post-test scores of the students in the experimental group regarding their metacognitive learning strategies and self-regulated learning skill levels. In addition, the study findings revealed that there was a significant difference in favor of the experimental group between the scores of the experimental and control groups regarding metacognitive learning strategies and self-regulated learning skill levels. On the other hand, the findings on student opinions showed that students generally had positive opinions about the mind mapping method. In addition, the use of the mind mapping method had significant contributions to the students' metacognitive learning strategies and self-learning skill levels. Considering the results of this study, the use of the mind mapping method in web-based courses significantly supported the metacognitive learning strategies of the students and contributed positively to the increase in self-learning skill levels.
