一、例题教学中例题应具有的特性1.例题要精心设计要有典型性数学题成千上万,例题的选择要克服贪多、贪全,要关注知识点的覆盖面,要让学生能通过训练掌握规律,并会发现规律,达到“以一当十”的目的.例题选择恰当与否,直接关系着学生对知识的理解和掌握,切不可盲目选择例题进行“满堂灌”.例题的选择不能过多,要有一定的基础性和代表性.教师不能在选择例题时贪多求全,造成“大容量”或是例题叠加,机械重
First, the sample teaching should have the characteristics of the examples 1. Example should be carefully designed to have tens of thousands of typical mathematical problems, the choice of examples to overcome the greedy, greedy, to pay attention to the coverage of knowledge points, to allow students to pass Training to master the law, and will find the law, to achieve the purpose of choosing the appropriate or not, the case is directly related to the students’ understanding and mastery of knowledge, must not blindly choose the examples to carry out Not too much, there must be a certain degree of basic and representative teachers can not be more than enough choice in the choice of examples, resulting in “large capacity ” or the case superimposed, mechanical weight
