机械原理课程的授课对象是第四学期的机械设计制造及其自动化专业学生，他们缺乏工程知识、实践经验，对课程涉及的机构结构学、运动学和动力学等内容会感到抽象和难学。仅靠教师在有限的课堂学时面授讲解众多知识点时，学生会很难充分理解课程的相关内容；他们还存在一定的惰性，理论学习兴趣不高、学习比较被动，对于传统讲授式课堂不感兴趣，在课堂上低头玩手机的比较多。

The teaching object of mechanical principle course is the students majoring in mechanical design, manufacturing and automation in the fourth semester. They lack engineering knowledge and practical experience, and feel abstract and difficult to learn the contents of mechanism structure, kinematics and dynamics involved in the course. It is difficult for students to fully understand the relevant contents of the course only when teachers give face-to-face instruction and explain many knowledge points in limited classroom hours; They also have some inertia. They have low interest in theoretical learning, are relatively passive in learning, are not interested in the traditional teaching class, and are more likely to bow their heads and play with mobile phones in class.

The course of Mechanical Principles is taught to the students majoring in mechanical design, manufacturing and automation in the fourth semester. They lack engineering knowledge and practical experience, and they will feel abstract and difficult to learn about the contents of the course, such as mechanism structure, kinematics and dynamics. It is difficult for students to fully understand the relevant contents of the course when teachers only explain many knowledge points face-to-face in limited classroom hours. They still have a certain inertia. They are not interested in theoretical study, are passive in learning, are not interested in traditional lecture-based classes, and play with their mobile phones in class.
