波利亚曾说过:“如果你想学会游泳,你必须下水;如果想成为解题能手,你必须解题.”因此数学解题作业的布置成了有效教学过程中的一个重要环节.目前,相当部分的教师在设计教学方案时,对课堂教学给予了充分的关注,但并没有对作业的设置给予同样的关注,多数时候只是从教材或配套教辅书上选择一些题目作为学生作业,有时这种选择甚至是随意的!事实上,这也是造成数学作业“高密度低质量”的根源所在!本文就优化数学作业的设计作了如下的阐述.
Polyana once said: “If you want to learn to swim, you have to go into the water. If you want to be a problem solver, you have to solve it.” Therefore, the placement of math problems is an important part of an effective teaching process At present, a considerable part of the teachers in the design of teaching programs, given adequate attention to classroom teaching, but did not give the same attention to the operation of the settings, most of the time only from the textbook or supporting supplementary books to select some of the topics as students In fact, this is the root cause of math homework “high density and low quality”! This paper elaborates on the design of optimizing math homework.
