| Function is the core content of middle school mathematics,good processing function of junior high school teaching,let the students grasp the function thought is very important to the whole high school mathematics learning,for other subjects of study will have a positive impact.In this paper,through literature research,questionnaire survey and case interview,combined with the case,the main research the present situation and countermeasure of junior high school function concept,rich practical problems with the construction of a specific function model between the status quo and countermeasures.This article mainly from the function concept,function,image,function and the inequality,the equation of three dialectical relationship of teaching and learning situation investigation,analysis of the concept of the function complexity,it is difficult for the students’ cognitive characteristics;Based on the current situation of the function application,the paper analyzes the practical application part,and the information is large.Some students rely on the teacher to explain,and explore the characteristics of the lack of consciousness.From primary and high cohesion function teaching present situation investigation and analysis for the need of the high school class,as the content of teaching material on the depth and breadth to expand,the students’ cognitive structure of different characteristics.This paper also investigates the students,learning strategies from the teaching strategies of teachers.Aiming at these problems,the author from the perspective of teachers’ teaching and students learn to study,analysis of teachers’ teaching is not only to prepare the teaching material,to prepare students to find students,the zone of proximal development put forward the problem to be operational,build the classroom efficiency evaluation,it is concluded that the corresponding solution strategy,and the corresponding strategies to solve the problem on the two case intuitive display. |
