This research started with the question as to what effects and influences the mutual interaction between sports climbing teacher and learners will bring about to the study targets of “Teaching and Learning”, while I am using the PBL as its research method with the sample group consisting of the students majoring in Sports for All. At first they didn’t even understand how the PBL is different from the existing learning methods of techniques and how to use the group training session but, as they interacted with each other with the teacher playing the roles of manager, guide, helper, and coach, they got used to it. And, in the process of being preoccupied with the learning, the learners with the previous on-spot experiences of leisure activities were better in self-initiating activities and in the depth and precision of understanding the results than other learners, when it comes to their learning performance, which naturally led them to get equipped with the characteristics of leaders. Lastly, learners answered PBL is effective and appropriate in enhancing technical skills and teaching abilities, the aims of learning, but they also said the effectiveness and influences could be different, depending on how teacher use PBL, by which I confirmed the teacher play very important roles.
