一、设置大作业的目的建筑力学课程是土建类专业的骨干课之一,讲授时必须考虑与后续专业课的关系,避免与其他后续课程产生断层。但纵观土建类专业后续专业课的教学和学生的毕业设计答辩,发现很多学生在毕业设计中不能很好地应用力学知识,尤其是把实际问题抽象为力学模型的能力较差。究其原因,主要还是在以往的教学中,教师多注重力学本门课程的系统性、知识性,而忽略了它的实用性,所以学生面对一个完整实际的结构或构件问题便显得手足无措, First, set the purpose of large-scale operations Building mechanics course is one of the backbone courses of civil engineering, teaching must consider the relationship with the follow-up professional courses, to avoid faults with other follow-up courses. However, taking a look at the follow-up courses of civil engineering majors and students’ graduation design defenses, it is found that many students cannot apply the knowledge of mechanics well in graduation design, especially the ability to abstract actual problems into mechanical models is poor. The main reason is that in the past teaching, the teacher paid more attention to the systematic and knowledge of the mechanics of the course, and neglected its practicality. Therefore, students face a complete practical structure or component problem and become helpless.
