水中での自己保全能力を高める大学水泳授業の教育効果と教育成果の検証

The purpose of this study was to verify the educational effectiveness and outcomes of university swimming classes for enhancing self-preservation skills in the water, which had been formulated by Yamanaka et al. (2022), and to re-structure the teaching theory for these skills based on their design. Educational effectiveness was evaluated in terms of changes in students' water movement skills and a questionnaire survey. For analysis of changes in water movement skills, we used the results of 10-minute drifting, 12-minute swimming, and Stallman's skill check. Also, to analyze the educational outcomes of the class, we qualitatively analyzed the assignments in the class report to the students. The results of the skill measurements showed that the percentage of students who successfully achieved the 10-minute drifting and 12-minute swimming tasks was significantly higher in the last class session than in the first. In addition, for all measurements, the percentage of students who answered “I can do” in the last class session was significantly higher than in the first. Analysis of the class reports confirmed that the students were able to achieve the set objectives and tasks of the class. Consequently, the teaching theory for self-preservation ability in the water was re-structured by: (1) giving students the opportunity to experience coping with water disaster based on water movement skills and knowledge of underwater safety, (2) letting students experience various aquatic activities, (3) allowing students to recognize their own self-preservation skills in the water, and (4) enhancing the ability of students to cope with water disaster situations by allowing them to think of their own responses.
