许多老师教应用题的常规思路是先让学生记住解应用题的步骤:读题,审题,找相等关系,设未知数,列方程,解方程,答。然后再把应用题归成几种类型来讲解,每类问题都做成一个模板;在平时问题中只要让学生对号入座即可;这样造成的后果就是许多成绩中等偏下的学生会去死记硬背,这是学数学的大忌,这样教学最终把学生教死了,学生一旦遇到新的类型应用题时,或者应用题的题目一长,数量关系一多,学生就会惊慌失措,感到无从下手,久而久之,学生就会一遇到应用题就会感到头痛,对应用题就会从心里想避而远之。那么怎样才能比较好地解决这个问题呢?结合教学经验来谈谈教应用题的策略。
Many teachers teach the general idea of the application of the problem is to allow students to remember the steps to solve the problem: reading questions, examining questions, find the same relationship, set unknown, column equations, solve equations, answer. Then the application questions into several types to explain, each type of question is made into a template; in normal problems as long as the student condemnation can be; so the result is that many students with lower grades will go to memorization, This is a taboo to learn math, teaching eventually teach students to death, students encounter a new type of application problems, or the problem of a long application questions, the number of more than one, students will panic, feel helpless As time passes, students will feel the headache when they encounter the application question, and they will try to avoid it from the heart. So how can we solve this problem better? Combine teaching experience to talk about teaching strategies.
