方程是应用广泛的数学应用工具,它在义务教育阶段的数学课程中占重要地位。中考中方程常与不等式、函数问题结合在一起,分值比例比较大,而很多同学都会感觉应用题太难了,学也学不会,甚至放弃了。针对这种情况我研究了一套学习应用题的优化方法。一、联系生活实际,应用题难变易新课程标准提出:教师在教学中要根据学生的认知水平和生活经验挖掘学生生活和身边的实际问题进行选材,使学生更容易接受,更好理解,使应用题由难变易,如在讲解七年级数学
The equation is a widely used mathematical application tool, which plays an important role in mathematics curriculum in compulsory education. In the middle school entrance examination equations and inequalities, function problems together, the score ratio is relatively large, and many students will feel the application of the title is too difficult, learn also learn, or even give up. In response to this situation I studied a set of optimization methods to study the problem. First, contact with the reality of life, the application of the subject is difficult to change the new curriculum standards: Teachers in teaching should be based on the cognitive level of students and life experience to tap students living and practical issues around the selection of materials to make students more receptive, better understanding, Make the application difficult to change easily, as in the seventh grade mathematics
