在初中数学课堂教学中,许多学生上课时,总是皱紧眉头,神情很严肃的样子,他们在苦恼,在冥想,为何上了中学以后,数学题目就越来越难了呢?他们经常会为自己无法独立完成数学题而苦恼。那么,该如何帮助他们走出困境,让笑容重新挂在他们的脸庞呢?在此时,如果让学生们合作学习,优势互补,或许能解决难题。而合作的时机该如何把握呢?下面就我的教学实践,浅谈一下自己的一些做法和体会。一、在一个人完成有困难时学生因为解题经验较差,他们在做题目时,经常会遇到一些无法独立完成的题目,在这种情况之下,我们可以创设一些学习情境,让他们在小组合作中完成任务,培养他们团结协作的精神。例如,在学《平均数》时,我给出书上的例题:学校广播站要招聘一名记者,小明、小亮和小丽报名参加三项素质测
In junior high school mathematics classroom teaching, many students in school, always frowned, look very serious look, they are distressed, in meditation, why the secondary school, math problems more and more difficult? They often Disturbed by the fact that I can not complete math problems independently. So, how to help them get out of their predicament and let their smile re-hang on their faces? At this time, if the students cooperate with each other and learn from each other’s strengths, the problem may be solved. And the timing of cooperation how to grasp it?
