一、前言高中数学教学的重要性在于开发学生智力、培养学生发散思维能力、挖掘学生创造性的内在潜力,使学生能够全面发展。在此基础上培养和塑造学生的分析问题以及解决问题的基本能力。数学学科的基本培养目标是开发学生的发散思维,更新其解题思路,锻炼其运算能力,开发其智力和内在潜力,通过这些培养与锻炼最终提高学生观察、分析、评价和总结能力,对提高其思维的条理性和清晰度,起到不容置疑的作用[1]。数学学科的培养目标以及其学科特点决定着高中 I. Introduction The importance of high school mathematics teaching lies in developing students’ intelligence, developing students’ divergent thinking ability, exploring students’ inherent potential of creativity and enabling students to develop in an all-round way. On this basis, we should train and shape the students’ analytical problems and the basic ability to solve the problems. The basic training goal of mathematics is to develop students ’divergent thinking, update their problem-solving ideas, exercise their computing power and develop their intelligence and inherent potential. Through these trainings and exercises, students’ abilities of observation, analysis, evaluation and summarization will be improved finally. The rational and clarity of their thinking play an indisputable role [1]. The training objectives of mathematics and its disciplines determine the high school
