由解几复习课探索高考备考优质高效之路

Analysis of Efficient Method of University Entrance Examination Preparation Base on Analytic Geometry Review Lesson

为了解决高三备考中遇到的时间紧，内容多，题形新等问题，本人在解几复习专题中，由三方面切入：（1）如果用几何或代数知识都能解决的问题，就首先选用几何知识，使抽象的问题形象化，具体化，优化思维过程：（2）解决一道典型的问题以后，把它的条件改变，引导学生探究它的结果变不变？加强题目的引伸变换，拓展学生思维的深度和广度；（3）引导学生一题多解，提高学生的运算能力，逻辑思维能力和分析问题和解决问题能力。

In order to solve the problems in preparation of grade three in senior middle school such as time limited or overmuch contents or new types of questions an so on, this thesis discusses three aspect to improve the efficiency of students＇ exam preparation in analytic geometry, they are： firstly, ifa question can be solve both by geometry and algebra, chose geometry first, that can make a abstract question specialize and visualization,and optimize the thinking process; secondly, explore that if its result changes as the cause changes question when finished; thirdly, guide the students solve a question with kinds of methods and improve the students＇ circulation ability, logical thinking style and problem analysing and solving ability.
