Research On Strategies Of Stratified Teaching Of Ninth Grade Mathematics Under The Perspective Of Core Literacy

The core of this paper is to explore the application of stratified teaching in ninth grade mathematics and the cultivation of students' core literacy.In the previous investigation literature,there are many studies on the core literacy of mathematics of students,but most of them are carried out from the theoretical perspective through literature study and comparative study,and lack of specific research deep into the stratified teaching of mathematics.Therefore,this paper,with core literacy as background,combined with stratified teaching,on the basis of analyzing the core mathematics literacy of ninth graders,further explores the strategy of ninth grade mathematics stratified teaching under the perspective of core literacy,so that its core literacy is further developed.The content of this study mainly includes the following two aspects:(1)Analyze the student's core literacy and learning status,and find out the problems existing in the practical application of stratified teaching in ninth grade under the perspective of core literacy in classroom teaching;(2)The relevant strategy of ninth grade mathematics stratified teaching under the perspective of core literacy is put forward.The research studies method include the literature research method,the investigation research method and the case study method.Through literature research,the connotation and theoretical basis of core literacy,mathematics core literacy and stratified teaching are clarified,and the definition of core literacy mathematics core literacy and stratified teaching are made to lay a theoretical foundation for this study.Through questionnaire,the present situation of mathematics core literacy of ninth graders is investigated to find out the problems existing in the implementation of stratified teaching under the perspective of core literacy.According to the survey,there are three main problems in the implementation of stratified teaching under the perspective of core literacy:(1)The school plays no attention to the cultivation of students' core qualities,and the theoretical knowledge of teachers is limited,and lack of understanding of stratified teaching;(2)Students do not really understand the significance of cooperative learning,the use of calculation methods is improper,the mathematical operation ability needs to be improved;(3)Students are not aware of their subject status,logical reasoning ability has not been strengthened.For the problems found in the survey.In view of problems found in the survey,this study attempts to put forward three strategies for the stratified teaching of ninth grade mathematics under the perspective of core literacy:(1)Core literacy to change the teaching concept of teachers to form an effective stratified teaching model;(2)Emphasis is paid to the use of calculation methods in stratified teaching to improve students' mathematical operation ability;(3)Enhance students' subject status and cultivate their logical reasoning ability in stratified teaching.Finally,according to the teaching strategies constructed in this study,the process and method of stratified teaching of ninth grade mathematics under the perspective of core quality are shown through classroom recording.
