高中新课程数学教材的＂教＂与＂用＂——函数概念的教学设计

＂Teach＂ and ＂Use＂ of Maths Textbook in Senior High School New Course——The Teaching Design of Conceptual of Function

具体实例和探究比例在新教材中有所上升,这有助于指导学生去思考更多的知识.函数的概念也是通过设置三个具体的例子来诱导阐述的,它来源于具有新的课程设计结构的实例,新教材和新课标有着密切的联系,这有利于老师的教学,尤其有利于学生更深刻的了解函数的概念.

Proportions of the special instances and exploration increased in new textbook, which can guide the students to think the new knowledge. The concept of function is induced by set via three special instances. The concept of function is drawn from the special instances with new designed structure. The new textbook follows closely the new curriculum, which mainly to the students and secondary to the teachers.
