关于弹性力学的绪论与总结课堂教学探讨

Discussion of Teaching on Introduction and Generalization for Theory of Elasticity

弹性力学是变形体力学的重要组成部分,对本科生进一步学习其他固体力学课程起到奠基石的作用。笔者在课堂教学实践中发现,绪论部分和总结部分对于本科生从产生兴趣、积极思考、形成局部认识到整体认识等阶段起到关键作用。因此,笔者主要在绪论部分通过生动的介绍弹性力学发展史和具体案例与学生互动,让弹性力学吸引学生,调动学生学习的自主性和积极性。在总结课时,系统归纳弹性力学,让学生从局部认识提升到整体认识,提高课堂教学质量。让学生在学习弹性力学时从畏难和被动接受知识到主动思考,再上升到有兴趣学习此门课程。

Elastic mechanics is an important part of deformation mechanics, which plays a role in the foundation for undergraduates to further study other solid mechanics. Both preface and summary play a key role for generation of interest、positive thinking、as wel as formation of the overal understanding from the local knowledge. Therefore, in the preface Couse the author mainly interacts with the students through vividly introducing the development history of the elastic mechanics. The elastic mechanics wil attract the students and can mobilize students’ autonomy and initiative. In summary Couse, elasticity is systematical y concluded, so that the undergraduates enhance the overal understanding from the local knowledge and improve the quality of Couse teaching. The students wil change from fear of learning elasticity and passive acceptance to active thinking, and then who are very interest in learning this course.
