The purpose of this thesis is to closely examine the relationships among achievement goal orientation, motivation, and learning flow. In the study, the learners with distinct learning goals and enjoy the process of learning itself and the learners who study for the reward will show striking differences in their goal achievement level and participation in learning activities. Therefore, this study focuses on the flow, a psychological phenomenon that learners participate actively in the learning environment that is related to the learners\' affective characteristics and do the cooperative learning activities. If the learner\'s learning activity itself motivates to the action that becomes the purpose, it will produce satisfaction and accomplishment and lead to active learning process. In order to study further, a junior highschool and a highschool from “S” city and “K” city in Chonnam province were chosen randomly, and the survey was done to the students except the freshmen and seniors. As the result of this study, students with higher academic background had high performance goals and self-determined extrinsic motivations but low on learning flow. This, in fact, suggests that highschool students in present entrance examination centered education process don\'t study for any satisfaction nor pleasure from school teaching or learning activities but study for more external factors such as good results for the exams.
