内孤立波的线下线上融合式教学模式

Exploring the Offline and Online Integrated Teaching Mode of Internal Solitary Waves

摘要: 围绕海洋流体中内孤立波知识点，统计五届海洋学专业学员任务单测评数据，分析中尺度现象——内孤立波理论教学中存在的不足，总结出需要改进的问题，进而有针对性地探索线下线上融合式教学模式。该模式坚持学为主体、理实一体的教学理念，采用理实结合、虚实结合的教学方法，尝试在实验实操 + 仿真拓展的教学过程中，重塑学员海洋环境知识体系，加深学员对内孤立波运动特征的认识，教学效果得到显著提升。

Abstract: Based on the knowledge of internal solitary wave in marine fluid, this paper collects the assess-ment data of the task order of the fifth session of oceanography students, analyzes the shortcomings in the teaching of mesoscale phenomenon—internal solitary wave theory, summarizes the problems that need to be improved, and then explores the offline and online integrated teaching model. This model adheres to the teaching concept of learning as the main body and integrating science with reality, and adopts the teaching method of combining science with reality and virtual with reality. In the teaching process of experimental practice and simulation expansion, it tries to reshape the students’ knowledge system of marine environment, deepen the students’ understanding of internal solitary wave movement characteristics, and the teaching effect has been significantly improved.
