不等式在高中数学理论基础中占有很重要的地位,是进一步学习数学和解决其他数学问题的基础及便利工具.由于新课程改革之前不等式的教学更多地侧重性质、解法和证明,偏离了不等式学习的实际情境,不利于建立抽象模型,解决实际问题.根据笔者多年的教学经验,在下文中主要是针对苏教版高中数学一元二次不等式教学的体会,以供借鉴和参考.一、衔接初中不等式知识高中不等式的教学要设置初高中数学课程的衔接,针对初中课程未涉及,课堂没有学到但高中要运
Inequality plays an important role in the mathematical theory of senior high school, which is the basis and convenience tool for further study of mathematics and solving other mathematical problems. Since the teaching of inequalities in the new curriculum reforms focused more on the nature, solution and proof, deviating from Inequality Learning The actual situation is not conducive to the establishment of abstract models to solve practical problems.According to the author’s years of teaching experience, mainly in the following text is for the Sujiao version of high school mathematics one yuan quadratic inequality teaching experience for reference and reference. Knowledge of high school inequality teaching to set the connection of maths curriculum in junior and senior high schools, for the junior high school curriculum is not involved, the classroom did not learn but the high school fortune
