一、问题的提出高中数学教学课时紧,任务重,学习内容量大面广,需要学习众多抽象的数学概念、法则以及严密的逻辑推理,并做大量的习题,学生普遍感觉难学。常常有学生在学习过程中记不住数学公式,从而影响解题的数度与质量,导致数学学习效率低下,成绩不尽如人意。然而数学公式是高中数学知识中的重要组成部分,是数学推理论证的重要依据。许多核心知识点都以公式的形式呈现,如,基本不等式、两角和与差的三角函数、正余弦定理等。学生 First, the question raised High school mathematics teaching class is tight, heavy tasks, learning a wide range of content, you need to learn many abstract mathematical concepts, rules and strict logical reasoning, and do a lot of exercises, students generally feel difficult to learn. Often, students can not remember the mathematical formula in the learning process, thus affecting the number and quality of problem solving, resulting in inefficient math learning and unsatisfactory results. However, mathematical formula is an important part of high school mathematics knowledge, which is an important basis for mathematical reasoning and argumentation. Many core knowledge points are presented in the form of formulas, such as basic inequalities, trigonometric functions with difference and difference, cosine and cosine theorem. student
