“列方程解应用题”是初一学生首先碰到的难点,同时也提供了培养分析能力的极好机会。对应用题列方程没有机械刻板的方法,全靠根据题意分析。一个学习较好的高中学生可能一看题目就能写出方程来,一个刚进初中不久的学生就没有这个本领了。在开始讲授时,重要的是建立起合适的思考程序,也就是说,教师要指导学生按步骤解答问题。第一步:理解题意。在教学中经常有这样的事,学生向教师发问:“老师,这个题我不会做。”当老师与发问学生一起看题时,发问学生未等老师开口,就连说会了会了。这充分说明理解题意的重要。要正确理解题目里某些语句的意思。比如,在匀速运动里的速度是每天、每小时、每分钟还是每秒钟走的路程。第二步:设立未知数。设立未知数,一般说来是题目问什么,我们就设什么。有的题目问的是几个问题, “Columns Equations Application Problem” is the first difficulty students encounter, but also provides an excellent opportunity to develop analytical skills. There is no mechanical method for formulating column equations, all based on the analysis of the questions. A better learning high school students may look at the title will be able to write equations, a junior high school students just do not have this ability. At the beginning of teaching, it is important to establish a suitable thinking process, that is, teachers should guide students to answer the questions step by step. The first step: understand the questions. In teaching, there are often such things. Students ask teachers: “Teacher, I will not do this question.” When the teacher asked questions with the students, they asked the students not to wait for the teacher to speak out. This fully shows the importance of understanding questions. To correctly understand the meaning of some of the statements in the title. For example, the speed in constant motion is daily, hourly, minutely or per second. The second step: the establishment of unknown. The establishment of unknowns, generally speaking, what is the subject, what we set up. Some questions ask a few questions,
