一、有效预设,激发学生探究兴趣好的教学设计是上好一节课的前提条件。现在的学生对于新鲜事物比较感兴趣,好奇心强,思维比较灵活。面对数学枯燥的概念、难记的规律、复杂的实验,教师和学生应共同学习探讨、平等对话。教师在教学过程中应引导和帮助学生创造性地研究和解决问题并求得自身发展,教师要找一些能刺激学生的好奇心的资料,使学生产生探索的兴趣。例如在高中课本函数的奇偶性这节课的教学中,我结合数学课程标准和教学目标 First, the effective presupposition, to stimulate students to explore the interest of good teaching design is a prerequisite for a good lesson. Now students are more interested in new things, curiosity, more flexible thinking. In the face of the concept of maturity of mathematics, the law of hard to remember, and the complicated experiments, teachers and students should learn and discuss together and have an equal dialogue. Teachers should guide and help students to creatively study and solve problems and seek their own development in the teaching process. Teachers should find some materials that can stimulate students’ curiosity and make students have an interest in exploring. For example, in the teaching of this lesson in the parity of high school textbook functions, I combine mathematics curriculum standards and teaching objectives
