解析几何在培养学生函数思想、数形结合、基本量、整体运算、坐标等数学观点和思想以及配方换元等运算能力方面起着非常重要的作用,因此在每一张高考试卷中,都会出现,而且占的比例还不少(通常24～30分左右),但这一类题,往往成为学生的一个难点,其关键的问题是学生难以克服计算关,尤其是解二元二次方程组及整体运算,本文我结合自身的教学实践以及学生在解题中出现的种种困惑,谈谈如何优化解析几何的答题步骤。
Analytic geometry plays a very important role in cultivating the students’ functional thinking, number and form combination, basic quantity, overall operation, coordinates and other mathematical ideas and ideas, as well as the formula for yuan and other computing power, so in every college entrance examination papers, there will be , But also accounted for a small proportion (usually 24 to 30 minutes or so), but this type of question, often become a difficult student, the key problem is difficult for students to overcome the calculation of Guan, especially the solution of binary quadratic equations And the overall operation, this article I combine my own teaching practice and students in the problem-solving appeared in the various puzzles, talk about how to optimize the analytic geometry of the answering steps.
