摘  要：该文基于雨课堂教学工具对传统教学模式进行改革，采用“线上”“线下”混合式教学模式对2019级理论力学进行教学改革、探索，并且对比分析改革前后的教学效果。结果表明，基于雨课堂的混合式教学模式实现了学生课前预习、课上互动以及课后动态跟踪的完整教学体系，学生期末考试成绩明显提高了。通过问卷调查发现，教学改革后，学生学习理论力学的兴趣得到了改善，大部分学生对混合式教学模式的教学效果比较满意。该文的教学模式可以为开展线上线下混合式教学模式教学工作提供一定参考依据。

Abstract： Based on the rain classroom teaching tool， this paper reformed the traditional teaching mode， adopted the "online" and "offline" mixed teaching mode to reform and explore the teaching of theoretical mechanics of Grade 2019， and compared and analyzed the teaching effects before and after the reform. The results show that the mixed teaching mode based on rain class has realized the complete teaching system of students' preview before class， interaction in class and dynamic tracking after class， and the students' final exam scores have been significantly improved. Through the questionnaire survey， it is found that after the teaching reform， students' interest in learning theoretical mechanics has been improved， and most students are satisfied with the teaching effect of the mixed teaching mode. The teaching mode of this paper can provide some reference basis for the development of online and offline mixed teaching mode.

理論力学可以为工程实际问题的简化和计算提供必要的理论支撑，是多数工科专业必修的一门基础力学课程，该课程理论性强并具有一定的抽象性和复杂性[1-2]。理论力学的讲授应该注重培养学生的逻辑思维和抽象思维，提升学生分析问题、解决问题的能力，该课程是工科专业接触的第一门力学，学习的好与差直接影响后续其他力学课程（如材料力学、结构力学等）的学习[3]。《理论力学》传统的教学方式是以老师讲解为主，学生课下自学为辅，学习处于被动模式，师生沟通不足。有的学生羞于和教师进行交流、讨论，以至于问题越积越多，最终导致课上听不懂，课后完不成作业，久而久之失去了学习的兴趣。……
