The purpose of the study is to investigate the effects of concept mapping on mastery goal orientation and academic self-efficacy in a collaborative learning environment. The current study employed a randomized controlled pretest-posttest group design to examine if learning strategies such as concept mapping can help students with both reading comprehension achievement and intrinsic motivation of wanting to master a task at a high level. A total of 42 5th grade students at Ilshin Elementary School in South Korea participated in this study. The experiment group (n=22) has undergone concept mapping training while the control group (n=20) has not. All students were required to fill out questionnaires based on mastery goals, performance goals and academic self-efficacy. The results indicated that concept-mapping did not increase mastery goals and mastery goals had no effect on test scores. In addition, the interaction effect between academic self-efficacy and condition did not increase mastery goals and had no effect on test scores. In conclusion, the reduced number of samples may have caused a potential source of instability considering the statistical procedure chosen.
