Study Of Function Teaching In Senior High School Based On Mathematics Core Literacy

In 2017,Ministry of Education issued and implemented Curriculum Standard for Senior Mathematics which put forward Mathematics Core Literacy.The core literacy indicates the direction to the new curriculum reform.Mathematics Core Literacy is the concentrated reflection of math curriculum aims.Therefor,how to develop students,Mathematics Core Literacy in mathematics teaching has become a focus issue in educational circles recently.Function is the core content in high school math,which combine a variety of math knowledge.There exist rich math thoughts and methods in function,which is good material for cultivating Mathematics Core Literacy.Therefore,this study aims to direct function teaching in senior high school based on Mathematics Core Literacy.Meanwhile,we hope to promote the effective carrying out of Mathematics Core Literacy in senior high school's function teaching.This passage adopts documentation method,interview method and classroom observation.I have interviewed some students who have graduated since 2018 and some in-service senior high school math teachers.I have attended some function classes taught by other colleagues.I have also summarized my teaching experiences for six years.I have found some problems in function's teaching and leaning.And I want to explore how to direct senior high school function teaching based on Mathematics Core Literacy from five aspects,the correct understanding of function concept,the comprehensive use of function properties,the absorption of function thoughts and methods,the deep knowing of function and differential coefficient,the exploration of null point.I hope to help some new teachers and many students to understand function more deeply.I also hope to help students master function,develop Mathematics Core Literacy and morality.Finally,I want to bring up some advice on senior high school function teaching and leaning based on my six years teaching experiences.
