理论力学教学方法探讨与实践

Discussion and Practices on Teaching Method of Theoretical Mechanics

摘要: 随着我校对专业课程和学分设置的改革，土木工程专业理论力学课时数降至为48课时。为帮助学生建立理论力学知识体系并培养他们的工程计算实践能力，教学团队对理论力学课程的教学方法进行了改善。首先我们在课程开始阶段强化学生薄弱的数学基础，在此基础上对教学组织，包括教材选用、教学内容和流程、工程计算实践能力培养方式上都进行了优化。同时我们还采用多种方式丰富教学质量过程控制手段，为激发学生的学习自主性提供外部动机。特别地，我们采用了复杂问题案例教学方法，以少数复杂问题覆盖该章节知识体系并以小组协作实践培养学生的工程计算能力。实践结果表明，改善后的教学方法能在有限课时前提下有效激发学生的学习兴趣和自主学习行为，明显提高教学质量并取得良好的学生反馈。

Abstract: As a consequence of the reform for major courses and credits in our university, the class teaching of Theoretical Mechanics reduces to 48 class hours in the major of Civil Engineering. To establish the knowledge system and the ability for engineering problem solving of students, our teaching team improves the course teaching method. We first intensify students’ week foundation of Mathematic in the beginning of course. On this basis, we improve the organizational form of teaching, including the selection of textbook, contents and process of courses, practical ability of solving engineering problems. Also, several manners are adopted for process monitoring of teaching quality to provide the external motivation for students’ independent study. Specifically, we apply the case teaching of complex problems covering the knowledge system of the chapter and team collaboration to cultivate the ability of solving engineering problems. The results indicate that the application of improved teaching method could effectively motivate the learning interest and self-regulated learning behavior, and obviously promote the teaching quality and achieves good feedbacks from students under the condition of limited course hours.
