RESEARCH ON TEACHING AND LEARNING OF THEORETICAL MECHANICS BASED ON CULTIVATION OF STEPPED MECHANICS THINKING

An output-oriented teaching and learning reform mode of theoretical mechanics is proposed based on the cultivation of stepped mechanics thinking. Firstly, the concept of stepped mechanics thinking is put forward, and mechanics thinking is divided into basic mechanics thinking, middle mechanics thinking and advanced mechanics thinking. Then the requirements of specific ability and the training mode of stepped mechanics thinking are given. Finally, an output-oriented teaching and learning mode with the training of mechanics thinking as the core is given, and the basic mechanics thinking is established through online and offline blended teaching. The middle mechanics thinking is established through the deep using of fusion case library. The modeling ability is cultivated through case library of video animation library, and the whole teaching process is integrated with the cultivation of advanced mechanics thinking. The results of teaching reform and mechanics competition in recent four years proved that this teaching and learning mode has achieved good teaching output.
