Current Situation Investigation And Practice Research Of On-line Mathematics Teaching In Middle School Under The Background Of Epidemic

With the rapid development of information technology,the integration of information technology and disciplines has become an inevitable trend in education,and the teaching mode of online teaching has also become a leader in educational informatization.At the beginning of 2020,the unexpected outbreak of novel coronavirus has led to the shift of the form of school classes from offline to online,and the shift of the classroom from the classroom to the Internet,showing a new form of education Therefore,investigating the actual situation of online teaching in high school mathematics during the epidemic period and summarizing the experience of online teaching is an important benchmark for exploring the teaching mode of high school mathematics in the post epidemic era.Based on the development of online teaching under the background of epidemic prevention and control,Grade 3 and Grade 2 of High school in Yulin City were taken as examples to discuss the effect of online teaching of middle school mathematics from multiple perspectives,hoping to provide reference for online teaching in the future.In the first chapter,the research background and significance of the subject,trends and methods of online teaching are described.Among them,the research trends of online teaching at home and abroad are summarized from the four aspects of middle school mathematics teaching,online teaching,online teaching of mathematics,and the application research of mixed learning in middle school mathematics classroom.In Chapter 2,a basic introduction to the concepts and educational theories involved in the thesis were provided,and the background and usage of online teaching and learning were introduced.In Chapter 3,in order to ensure the authenticity and validity of this research and to understand the online teaching situation exactly,the teacher version,student version and parent version of the online teaching questionnaire in a targeted manner were designed.Based on the results of the survey and interviews with front-line teachers about online teaching,the most realistic feelings and suggestions of different groups about online teaching were obtained,and the advantages and problems of online teaching were summarized.In Chapter 4,optimization strategies for the problems reflected in the questionnaire were proposed,including improving the online teaching environment,strengthening mathematics teachers’ information training and overturning previous teaching methods,changing students’ learning styles,and strengthening home-school contact.In Chapter 5,the online teaching model of the quality class was analyzed,and the online teaching processes for a specific case of secondary school mathematics to reflect the superiority of online teaching in secondary school mathematics were designed.Chapter 6 is an outlook on online teaching and learning.The "big test" of online teaching and learning in the era of "Internet+" has brought inspiration and reflection to educators,and the teaching and learning of secondary school mathematics in the post-epidemic era has shown a blend of online and offline development.In addition,the hybrid teaching strategy proposed by the author will provide reference and guidance for the subsequent mathematics teaching.
