要提高学生的解题能力,片面地强调作业数量是不妥当的,重要的是要研究和掌握教学规律,提高作业质量。我在这方面作了些尝试,也收到了一定的效果。一、教师必须超前亲自做习题。教师只有亲自做习题,才能深刻地领会和掌握教材的深度、广度、关键和难点,发掘教材和习题的内在联系,知道习题的难易及解题规律。例如,我们在超前做初中物理第一册第 148页(5)、(6)两题后,发现这两题让学生练习难度很大,于是,我们就设计程序练习题如下: 1、体积为1米~3的方木块浮在水面,露出水面部分是总体积的五分之二。求:(1)
To improve students’ problem-solving abilities, it is not appropriate to emphatically stress the number of assignments. It is important to study and master the laws of teaching and improve the quality of assignments. I have made some attempts in this area and I have also received some results. First, teachers must do their own exercises in advance. Teachers can only deeply understand and grasp the depth, breadth, key, and difficulty of textbooks by doing their own exercises, digging out the inner links between textbooks and exercises, and knowing the difficulty of exercises and the law of solving problems. For example, after we had advanced to do the first two pages of junior high school physics booklet 148 (5) and (6), we found that these two questions made it difficult for students to practice. Therefore, we designed the programming exercises as follows: 1. The volume is Blocks of 1m to 3m float on the surface of the water, revealing two-fifths of the total volume. Seeking:(1)
