高中数学新课程倡导通过各种不同形式的自主学习、探究活动,激发学生的学习兴趣,让学生体验数学发现和创造的历程.数学探究是新课程的一个重要特征,它是以独立思考和深度思维为主的探究活动.近年来各地的高考数学试卷,都设置有2—3道探究性试题,内容涵盖函数、数列、三角、几何等多个门类.试题常常表述为:是否存在…,使得…;是否为定值(最值)?你能得…结论吗?等等,其主要特征是结论不确定、方向不明朗,需要学生具备一定的自主探究的能力,构成了学生的难点.我们认为可以采用探究性的活动(观
The new high school mathematics curriculum advocates through various forms of autonomous learning and exploration activities to stimulate students’ interest in learning and let students experience the process of mathematical discovery and creation.Mathematical inquiry is an important feature of the new curriculum, which is based on independent thinking and depth Thinking-based inquiry activities in recent years around the college entrance examination math test papers, are set to explore 2-3 questions, covering functions, sequences, trigonometry, geometry and other categories.Experiments often expressed as: whether there is ..., so that ...; is it a set value (the most)? Can you get ... Conclusions? And so on, whose main features are the conclusion of uncertainty, the direction is not clear, requires students to have a certain degree of self-exploration capabilities, constitute the difficulties of students. Think that exploratory activities can be used (concept
