Study On Function Teaching Design Of Junior Middle School Based On Mathematical Abstract Literacy

Now,more and more teachers and educational researchers are focusing on core math literacy.Meanwhile the exploration of mathematics core accomplishment is deepening and improving continuously.Abstract mathematics,one of the six core accomplishments of mathematics,is the basic thought of mathematics and the important foundation for people to form rational thinking.It is the basic quality that every citizen in morden society should have.Since function has a high degree of abstraction and occupies a very large proportion in middle school mathematics curriculum,it is of great significance to study function and mathematical abstraction.This paper will solve the core problem of how to train students' mathematical abstract accomplishment and help them to understand and master the knowledge and content of functions by designing middle school function teaching.This article is divided into four main parts:The first part: mainly adopts the literature analysis method,by referring to the literature on mathematical abstract teaching design and function teaching,this paper analyzes the connotation and level division of mathematical abstract literacy.It lays a theoretical foundation for the teaching strategy and the principles of teaching design.The second part: teaching design is to arrange teaching elements in an orderly way according to teaching content,and to determine the presupposition and plan of appropriate teaching program.this part combines mathematical abstract theory,instructional design theory and functional teaching.It is concluded that the teaching design based on mathematical abstract accomplishment should follow the teaching principles of process development and interest,study the links of teaching design,and generate a theoretical system of functional teaching design.The third part: based on the theoretical basis of this paper,the principles and links of teaching design are integrated with the specific content,and three contents are selected from the teaching materials for junior middle school mathematics published by people's education edition,and the teaching design cases are given.In addition,the author wrote down the "design intention" of each link in the classroom teaching process in detail,and analyzed how the case embodied the mathematical abstract literacy.The fourth part: on the basis of exploring the design of junior high school function teaching based on mathematical abstract literacy,put forward four junior high school function teaching strategies to cultivate mathematical abstract literacy:(1)To create anappropriate teaching situation to inspire students to think.(2)Design exploratory and interesting mathematical activities and experience the process of mathematical abstraction.(3)Comprehend mathematical thoughts and methods,and develop mathematical abstract literacy.(4)Combine other qualities,combine mathematical abstraction with logical reasoning mathematical modeling,and realize common prosperity.
