The purpose of this study is to comprehensively investigate the relationship between learning motivation participation and performance related variables of adult learners participating in lifelong education. To do this, we conducted a meta-analysis based on 45 studies on motivation to participate in learning and learning for adult learners. The motivation for participating in learning was three types of goal orientation, learning orientation, and activity orientation proposed by Houle. The related performance was learning achievement including satisfaction with instructor, education contents, education environment/facilities, Social, leisure, physical, emotional, cognitive, self - growth, and life satisfaction. The results of this study are as follows: First, it is found that the relationship between learning motivation and performance related variables is moderate. Second, in the relation between learning outcomes and quality of life and the variables of learning participation motive type, learning orientation, activity orientation, and goal orientation were higher in order. Learning orientation, and activity orientation were found to have a medium level of correlation, but the goal orientation was confirmed to be lower than the middle level. Third, it was found that there were differences in the variables perceived as learning outcomes according to the type of participation. The motivation for adult learners to participate in learning is not uniform as school-age students. Therefore, various education should be carried out with different purpose of operation considering the content and goals of lifelong learning program, education method, lecturer, facilities.
