Promoting student learning skills is one of the important goals of school education. However, case studies involving educational practices suggest that students do not develop such skills to a level that would make them autonomous in learning. In addition, studies about school practices in Japan have suggested that efforts at developing student learning skills in schools are not adequate. To address this problem and to contribute to the promotion of student learning skills development, this paper examines relevant research areas including educational practices. It firstly introduces variations in learning skills suggested in the learning strategies research area. Secondly, it summarizes the developmental processes and factors relating to the use of learning strategies. Thirdly, the paper provides an overview of research areas and educational practices that promote the development of learning skills. Finally, it proposes a future direction to address the problem.
