高数变式多解“以学定教”模式的研究

On Higher Vocational Mathematics Variable Multi-solution Model Research

高等数学课堂教学中的变式多解要根据学情,“以学定教”,掌握选题、变式、解题的策略.选题是变题的基础,解题是教学的主体和教学的灵魂.把握教学大纲,围绕课程核心,提炼核心概念,精选教材例题和习题,概念、公式与各知识的变通要纵横联系,呈现变式解题的“研究策略”.变式按知识点分:定义变式,命题变式,问题变式等.

Higher mathematics is an important basic course of training skilled talents.The high number of choice and change of teaching,problem solving,can form a higher point of view,and widerand more rationalfield of visionto lead the math and thinking,and tograsp the philosophy of mathematics.In order to master the"three principles",topic is changedto grasp"the three degrees",and to grasp the ideas to solve problems.A moderate amount of choice and change(type),and the problem solving around the coreare neededto refine the core concepts,the concept of formula and the flexibility to vertical and horizontal contact of knowledge,and topresent the answer to key questions generated effectively.
