论数形结合法在经济学课堂中的应用

The Application of Combination of Number and Shape in Economics Class

数形结合法是数学领域运用几何方法解决代数问题的重要方法。经济学教学实践中一些结论往往需要复杂的数学知识,这会加大高职学生学习难度。尝试运用数形结合方法分析经济学的经典消费者结论,回答需求曲线为什么是直线、弹性临界值为什么为1以及运用弹性解释“谷贱伤农”的合理性这三个教学知识点,帮助学生重塑消费者需求理论框架。通过运用该方法,课堂教学有效地帮助学生理解经济学基本概念及理论,培养学生运用数形结合的方法解决现实经济问题的能力,进而提高学生学习兴趣,达到良好教学效果。

The combination of number and shape is an important method in the field of mathematics to use geometric methods to solve algebraic problems. However, some conclusions in economics teaching often require complex mathematical knowledge, which will increase the difficulty of learning for vocational students. This paper attempts to use the combination of numbers and shapes to analyze classic conclusions of economics, and try to answer the three teaching knowledge points of why the demand curve is a straight line, why the elasticity threshold is 1, and the rationality of using elasticity to explain the rationality of "low grains hurting farmers", To help students reshape the theoretical knowledge system of consumer demand. Through the use of this method,classroom teaching effectively helps students understand the basic concepts and theories of economics, cultivates students’ ability to use the combination of number and shape to solve real economic problems, and at the same time enhances students’ interest in learning, and achieves good teaching results.
