现行教学中.作业大都是学生做.教师改的传统模式.不利于物理教学质量的提高。一方面物理习题约70%属问答题.批阅会占用教师的大量工作时间;另一方面学生因学习负担较重不可能对批改后的作业作认真的思考、分析、纠正。这样.教师对作业的批改成了无效劳动。同时.还因初中每周只有三节物理课.作业信息反馈时间过长.不能及时校正。对此.笔者在近几年的教学中提索出用“做”、“批”、
In the current teaching, most of the work is done by the students. The traditional mode of teacher reform is not conducive to improving the quality of physics teaching. On the one hand, about 70% of physics problems are quiz questions. Marking will occupy a large amount of working time for teachers; on the other hand, students are unable to seriously think, analyze, and correct the revised work because of the heavy learning burden. In this way, the teacher’s correction of the work has become invalid. At the same time, because there are only three physics classes for junior high school students, feedback on work information is too long. It cannot be corrected in time. In this regard, the author mentioned in the teaching of recent years to use “do”, “buy”,
