习题训练是学生理解知识、运用知识解决实际问题的一个必不可少的环节,但现行教学中依然存在着“盲目训练”“题海战术”的不良训练习惯,学生深深地陷在“题海”中不能自拔。为提升物理训练的有效性,把学生从题海中摆脱出来,是目前物理教学中亟须解决的难题,而搞好“微专题”训练不失为一种有效措施。 Exercises training is an indispensable link for students to understand knowledge and use knowledge to solve practical problems. However, there are still some bad training habits of “blind training” and “sea tactics” in current teaching. Students are deeply trapped In the “title sea” can not extricate themselves. In order to enhance the effectiveness of physical training, it is an urgent problem to be solved in physics teaching to get rid of students from the sea of ​​questions. However, it is an effective measure to improve the training of “micro topics”.
