Research On Online Teaching Model Of Senior Middle School Mathematics Course Based On Core Literacy

With the continuous development of modern educational technology and the continuous advancement of basic education reform,online teaching has gradually entered the public's vision.In response to novel coronavirus period,in order to ensure the normal conduct of our country's educational career,the Ministry of Education put forward the call of "stop teaching,stop studying",all levels of all kinds of colleges and universities launched online teaching model.How to ensure the "substantial equivalence" between online teaching and offline teaching has become a hot issue.In this large-scale online teaching process,the advantages of online teaching have been fully demonstrated,but at the same time,many problems have been exposed,such as the development of online teaching platform is not mature,teachers and students are not adapted to online teaching.Since the promulgation of the Mathematics Curriculum Standards for Compulsory Education,the core literacy has become the focus of curriculum reform at home and abroad.Based on the cultivation of high school students' mathematics core literacy,this paper has carried out a research on online teaching strategies.On the basis of reading relevant literature,I have a certain understanding of the core literacy and online teaching,and specific research results are as follows:(1)From two dimensions of students and teachers,a questionnaire survey was conducted on some high school students who received online teaching,and individual interviews were conducted on teachers who participated in online teaching.To understand the learning situation of students in online teaching and the impact of online teaching on the core math literacy of high school students.This paper analyzes the data of the questionnaire by using the questionnaire star,Excel and IBM SPSS statistics 19.The results show that the questionnaire has good reliability and validity.(2)Through the analysis of the questionnaire survey,students' classroom performance records and teachers' interview records,the analysis results show that online teaching has a certain influence on the cultivation of high school students' core literacy in mathematics.Specific performance in the classroom performance of students,students' mathematics performance and students' application of knowledge.(3)According to the advantages and disadvantages of online teaching,this paper summarizes the teaching strategies of online teaching to cultivate students' core literacy,and constructs a hybrid online and offline teaching mode.(4)Taking "Function Monotony" as an example,the teaching design is carried out and teaching practice is carried out with two parallel classes of one senior high school in Gaizhou City as the object.The experimental class was given the mixed teaching mode,and the control class was given the online teaching mode.The learning effects of the two classes were compared.IBM SPSS Statistics 19 software was used to compare and analyze the math achievements of students before and after practice.The results show that : In online teaching,teachers can make teaching design according to the actual situation of students,which can better cultivate students' core literacy of mathematics.students in the mixed online and offline teaching mode have better math learning effect.Teachers should give full play to their leading position,according to the specific situation of the class of students to carry out teaching design to better play the advantages of online teaching.Therefore,the choice of appropriate online teaching mode is very important to the cultivation of students' mathematics core literacy.
