学生在解题后若能自我评价解题思路,探讨成功的经验,总结失败的教训,概括数学思想方法,那一定能达到提高解题能力和优化思维品质的目的.一、指导学生反思解题方法在解题过程中,不同的问题存在着不同的解题方法.做完题不是万事大吉了,而是要引导学生反思解决问题的方法,总结题目的类型,挖掘其中的内涵,提高解题能力.例1 7位同学站成一排,甲、乙不能站在排头和排尾的排法共有多少种?解法1(直接法)第一步(除去甲、乙)
Students in the problem-solving self-evaluation problem-solving ideas, discuss the successful experience, summed up the lessons of failure, summed up mathematical thinking and methods, it will certainly be able to improve the ability to solve problems and optimize the quality of thinking purposes. Methods In the process of solving problems, there are different ways to solve different problems.To complete the questions is not everything, but to guide students to reflect on ways to solve the problem, summarize the types of topics, to explore the content of which to improve the ability to solve problems Example 1 7 students standing in a row, A, B can not stand in the first row and tail row of the total number of row method? Solution 1 (direct method) The first step (except A and B)
