实行课程教材改革以来,根据新教材特色,努力改进教学方法,使学生既减轻负担,又提高能力。但能力的提高尤其是计算能力的提高,需有循序渐进的过程,要求教师在平时教学中逐步渗透。为此,作如下尝试:1.每日一题。结合教材内容,采用每天做一题的方法,逐步介绍计算中各种类型和方法,由易到难。例如,过量计算、多步反应一步计算、差量法、估算法、平均值法等等,让学生拓宽思路,充分运用题目中提供的信息巧解,提高学生兴趣分散难点。
Since the reform of the course materials, according to the characteristics of the new materials, efforts have been made to improve teaching methods so that students can not only reduce their burden but also improve their ability. However, the improvement of the ability, especially the improvement of computing power, requires a gradual process, requiring teachers to gradually infiltrate the teaching in peacetime. To do this, try as follows: 1. Daily questions. Combining the content of the teaching materials, using the method of doing one topic each day, gradually introducing various types and methods of calculation, from easy to difficult. For example, over-computation, multi-step reaction one-step calculation, differential method, estimation method, average method, etc., allow students to broaden their ideas, make full use of the information provided in the topic to solve the problems, and improve students’ interest in diffusing difficulties.
