传统的数学教学模式,一般都是教师进班级,出示一些复习题,学生举手回答完成,引入新课,在新课教学中往往都是出示例题学生试做,教师讲解,集体订正,然后做一些书中相应的题,教师总结这节课就算上完了。这种以老师为主的教学模式大大限制了学生的学习能力,因此,我们应该认识到:数学教学不是老师教学,而应最大限度地组织学生积极地开展数学实践活动,即“做”数学,也就是做数学研究。教学中应将学生放在主体位置上,让学生高高兴兴地进入数学世界,在探索中激起兴趣,从发现中寻找 The traditional mathematics teaching mode is generally teachers into the class, to produce some review questions, the students raised their hands to answer the completion of the introduction of new courses in the new course teaching are often produced sample students try to do, teachers explain, collective correction, and then do Some books in the corresponding title, the teacher concluded that the class is finished. Therefore, we should realize that the teaching of mathematics is not the teaching of the teachers, but should be organized to the maximum extent to actively carry out the activities of students in mathematics practice, that is, “doing ”, Mathematics, that is, to do mathematical research. Teaching students should be placed on the main position, so that students happily enter the mathematical world, to stimulate interest in the exploration, to find from the discovery
