在数学教学中,不仅要让学生学会参与,而且要让学生学会成功地参与。当学生获得成功的体验,就能增强参与的欲望,保证有效地投入学习。所以,对于相同年级而不同水平的班级在执行同一教学要求的前提下,在教学内容的安排上,根据学生的实际调整较为合理的坡度,由易到难,分层递进。对基础好的班级坡度应该大些,可以少设铺垫;对基础差一些的班级坡度应该小些,可以多设铺垫,使对于各种班级所设的铺垫都能确定在一个适当的数量级上,这样,全体学生都有参与学习的机会,思维就能逐级上升,有助于激起他们更强烈的学 In mathematics teaching, not only to allow students to learn to participate, but also to enable students to learn to participate successfully. As students gain a successful experience, they can enhance the desire to participate and ensure effective learning. Therefore, under the premise of implementing the same teaching requirement for classes of different grades in the same grade, the more rational adjustment of the teaching content should be made according to the students’ actual conditions, from easy to difficult and gradual progressively. On the basis of a good class slope should be larger, can be less paving the way; on the basis of some of the class slope should be smaller, you can set up more bedding, so that bedding for various classes can be determined in an appropriate order of magnitude, In this way, all students have the opportunity to participate in learning, and their thinking can escalate step by step, helping to arouse their stronger learning
