在新课程标准的背景下,高中数学函数的内容是整个高中数学教学的核心和重点部分,对教师的“教”和学生的“学”都提出了更为严格和具体的要求.它要求高中数学教师积极树立新的教学理念,摒弃传统的教学模式,对学生的学习心理进行深入研究,以学生作为教学的主体,探寻科学的,有效的教学方式,并通过师生之间的探究,合作与交流,帮助学生发展数学思维,并提高他们的数学探索能力,积极培养学生学习函数的兴趣,激发他们参与学习的动力,引导他们建立函数模型,并灵活 In the context of the new curriculum standards, the content of high school mathematics functions is the core and key part of the whole high school mathematics teaching, and puts forward more strict and specific requirements on teachers ’teaching and students’ learning. It requires high school mathematics teachers to actively establish a new teaching philosophy, to abandon the traditional teaching mode, to conduct an in-depth study of students’ learning psychology, to use students as the main body of teaching, to explore scientific and effective teaching methods, Explore, cooperate and communicate with students to help them develop mathematical thinking and improve their ability of mathematical exploration. They should actively cultivate students’ interest in learning functions, motivate them to participate in learning, and guide them to establish function models and be flexible
