Research Background and Motivation: This study delves into the potential of integrating marine education into water sports to enhance university students’ sense of place identity. The Tamsui River, with its rich biodiversity and cultural significance, serves as the perfect backdrop for this investigation. The study aims to enhance students’ connection to the local environment through hands-on experience, promoting marine conservation and environmental responsibility. The importance of this research lies in its potential to foster a deeper understanding and appreciation of the local environment among students, which could lead to more proactive efforts in marine conservation. Research Methods and Tools: The study adopts a single-group pretest-posttest quasi-experimental design. The subjects of this study are 20 students enrolled in a water recreation practice course. The course curriculum is designed to include self-rescue and canoeing technique training in the swimming pool, followed by outdoor canoeing activities in the Tamsui River. This combination of theoretical knowledge and practical experience aims to provide a comprehensive learning experience for the students. To measure the effectiveness of the course, learning motivation scales and place identity scales are used for pretest and posttest evaluation. Research Results: The study yielded promising results . After participating in the marine education course, students’ sense of place identity significantly improved, especially their sense of place attachment. This suggests that hands-on experience in a local environment can foster a stronger connection to the place. In addition, the scores of the marine education cognition test also significantly improved, indicating that the course effectively enhances students’ marine knowledge. Recommendations: Based on the findings of this study, it is recommended that water sports and marine education courses be further developed and promoted against the backdrop of the Tamsui River. This approach provides students with a deeper understanding of the local environment and fosters a sense of responsibility toward marine conservation. By doing so, it is hoped that students will gain a deeper appreciation for the Tamsui River and become more motivated to learn and protect the marine environment. Furthermore, exploring other teaching methods or tools to enhance students’ cognition of marine education is suggested. This could include using digital technologies or field trips to other marine environments.
