函数是刻画实际问题中数量关系的变化过程及规律的重要手段,它贯穿于整个高中数学教学过程的始终.传统的函数教学,以讲解为主,由于内容过于抽象,学生往往会感到枯燥和乏味,久而久之便会失去学习的激情.在现代化教育教学中,信息技术因共享化、自主化、个性化等特点,在各教学领域得到了普遍应用.巧妙地借助信息技术图、文、声、像并茂的优势,往往可以化抽象为具体,化复杂为简单,从而大大活跃课堂氛围,提高课堂教学有效性.因此,在高中函数教学中,教师要注意将信息技术与课堂教学有效整合起来,优选策略,巧妙地运用信息技术,激发学生的学习动 Function is an important means to describe the changing process and law of the quantitative relationship in practical problems, and it runs through the entire high school mathematics teaching process. The traditional function teaching mainly focuses on explanation. Because the content is too abstract, students often feel boring and boring , Over time will lose the passion of learning.In modern education and teaching, because of the characteristics of sharing, autonomy and personalization, information technology has been widely used in various teaching fields.Creally using information technology maps, text, sound and image Therefore, in the teaching of high school, teachers should pay attention to the effective integration of information technology and classroom teaching, and it is preferable that the teachers should pay attention to the combination of information technology and classroom teaching Strategy, clever use of information technology to stimulate students’ learning
