Investigation And Analysis Of Online Mathematics Teaching In Lhasa High Schools

In 2020,the emergence of global novel coronavirus pneumonia epidemic led to the comprehensive online teaching in Tibet to replace the traditional teaching mode in the past.Taking the opportunity of online teaching in Lhasa during the epidemic,This paper makes a detailed investigation on the current situation of online teaching in high schools in Lhasa,and analyzes the multi-dimensional and multi-visual comparison and in-depth analysis of online mathematics teaching before,during and after the epidemic,and gives some suggestions on the promotion and popularization of online teaching in the local area in the future.First of all,this paper expounds the research background of implementing online teaching from the development of Internet to promote educational reform,the special requirements of special period and the current situation and development needs of mathematics education in Lhasa senior high schools;Through the collection and summary of relevant literature,we understand the research status and development trend of online teaching,compare the advantages and disadvantages of online teaching and traditional teaching,and briefly introduce the theoretical knowledge involved in this paper;Secondly,the author studies the present situation of online mathematics teaching through various research methods,According to the actual teaching situation in Lhasa,the questionnaire and interview outline were designed,and 619 senior high school students and35 first-line mathematics teachers from four high schools,namely Beijing Experimental Middle School in Lhasa,Jiangsu Experimental Middle School in Lhasa,Beijing Middle School in Lhasa and No.2 Senior Middle School in Lhasa,were taken as the research objects.In-depth interviews were conducted with 10 mathematics teachers.According to the survey results,the implementation of online mathematics teaching in Lhasa has achieved initial results,but there are also some problems.At present,the problems existing in online mathematics teaching are as follows: 1)the network is unstable;2)lack of interaction in mathematics online classroom;3)poor self-discipline of students;4)the probability of online teaching being selected is low;5)parents' supervision is not in place;Then,the reasons for the existing problems are analyzed.The main reasons are as follows: 1.The implementation of online teaching in Lhasa is hasty;2.The school lacks management experience of online teaching;3.The online teaching platform itself is not perfect;4.Students' autonomous learning ability is weak;5.Students have not adapted to online teaching;6.Teachers' lack of understanding of online teaching;7.It is difficult for teachers to achieve "personalized teaching" in online teaching;Then,according to the current situation of online teaching in mathematics classroom,the relevant improvement strategies are put forward.Finally,combined with the online teaching design model and the results of the analysis,the teaching case of online mathematics teaching "Basic Theorem of Plane Vector" is designed to solve the existing problems.
