New Curriculum The Study Of The Function Concept Understanding Among Senior High Students

The function of this mathematical model can not only display the objective world butalso can depict dynamic phenomenon accurately. It is very important whether in practice or inacademic. But the function of this model is the start of the tool. Function is the top of highschool mathematics knowledge, it is the key to learn the high school mathematics, it can alsohelp student to understand to the abstract level leap. While most of the high school studentshave not understand.In order to understand the high school students to understand theconcept of the function, the writer did the questionnaire of the students and the interviews ofthe teacher.This article contains four parts: to begin with, according to the situation of the currenteducation, the writer describes the high school mathematics teaching is every important;what’s more, it introduces the theoretical basis of Bruner ’s, the discovery learningtheory,and APOS theory; third, according to the investigation and analysis of senior highschool students understanding of the concept of function, drew the following conclusions:(1)most of the ordinary senior high school students have the lack of a deep understanding of theconcept of function, involved related knowledge to grasp the overall relatively weak.(2)Toexpression method of the function, the Image of the function and the analysis type thefunction is better. To some extent, it is in the independent state.(3)The ordinary senior highschool students can not recognize the function symbol.(4)The ordinary senior high schoolstudents have not the ability to use the function. The fourth part, according to theinvestigation, the author gives some suggestions.
