Research On The Teaching Of Function In Junior High School Under The Core Literacy Of Mathematics

Under the core mathematical literacy,the teaching of function in junior middle s chool should be more vivid and vivid,guide students to master the concept,image an d nature of function,and also guide students to master the mathematical thinking meth ods contained in function knowledge.Develop good learning habits,and ultimately ac hieve the goal of developing core mathematical literacy.This paper through literature research,questionnaire survey,test papers,intervie ws,get the mathematics core literacy under the junior high school function teaching st atus,put forward the mathematics core literacy under the junior high school function t eaching strategy.(1)Pay attention to knowledge generation,infiltrate reasoning ability and model thought.(2)Pay attention to concept teaching,infiltrate model thought and symbol consciousness.(3)Pay attention to the combination of number and shape,infiltrate geometric intuition and operational ability.(4)Pay attention to integrating theory with practice,Permeate application consciousness and reasoning ability.Finally,according to the education theory,teaching situation and teaching strategy,four teaching designs are designed,which are " Concept of Linear Function","Concept of Quadratic Function","Concept of Quadratic Function" and "Image and Properties of Inverse Proportion Function".
