理解和掌握数量关系是正确选择算法的基础,也是解答应用题的关键。教学中常见这样的情况:学生知道题目要求什么问题,但却找不到相应的条件,尤其是对于复合应用题里的那些隐蔽的条件,更无法寻找,结果只能用猜想代替分析。究其原因,主要是学生没有理解应用题中数量之间的基本关系,同时分析和推理能力也较低。因此,要提高学生解题能力,教师应该经常不断地通过各种方法帮助学生理解和掌握应用题中的数量关系。下面谈谈我们的一些做法:
Understanding and mastery of the quantitative relationship is the basis for the correct choice of algorithm, but also the key to answering application questions. Teaching is common in such situations: students know what the problem requires, but can not find the appropriate conditions, especially for the covert application of those hidden conditions, but can not find the results can only be used instead of speculation analysis. The main reason is that students do not understand the basic relationship between the number of applications, while the analysis and reasoning ability is also low. Therefore, to improve students' ability to solve problems, teachers should constantly use various methods to help students understand and master the quantitative relationship among the applied questions. Here are some of our practices:
