自古以来合作就是人们赖以生存和发展的巨大动力,学会在活动中合作是课堂教与学不可缺少的环节。而当前的数学课堂教学,尤其是公开课,普遍存在流于形式、侧重表现表演的情况,实际上多数学生没有真正的机会参与思考讨论,这种教学状况长久下去是不能培养学生的创造力的。所以必须从源头上变革当前的数学课堂教学,尽可能地把机会留给学生,让他们在自主探究、独立思考中逐渐培养创造力。比如:在教授“平行四边形面积的计算”时,应该点拨学生自主回忆已学的三角形的面积公式的推导方法,让学生自主实践用两个完全一样的三角形拼成一个图形,进而推
Cooperation since ancient times is a huge driving force for people to survive and develop. Learning to cooperate in activities is an indispensable link in classroom teaching and learning. However, current mathematics classroom teaching, especially open class, is ubiquitous in terms of form and emphases on performances. Actually, most students do not have a real chance to participate in thinking and discussion. This kind of teaching situation can not cultivate students’ creativity for a long time. . Therefore, it is necessary to transform the current mathematics classroom teaching from the source and leave as many opportunities as possible for students so that they can gradually cultivate creativity in autonomous exploration and independent thinking. For example, when teaching “calculation of the area of a parallelogram,” we should call the method of deriving the area formula of the students who have learned to recall the triangles, so that students can independently practice the use of two completely identical triangles to form a graph, and then push
