| In recent years,with the rapid development of Internet technology,the mode of"Internet plus" education has become the theme of the new curriculum standard in twenty-first Century,and has set off a series of reform trends in education mode.MOOCS,micro courses,distance education,online classroom and a series of online teaching mode with its flexible and novel characteristics have been respected by teachers,students,parents and schools.After a series of reform and development of online teaching mode,hybrid teaching mode has gradually stepped onto the stage of history,thus realizing the combination of traditional education and online learning.At present,online teaching is widely used in all aspects,and has achieved certain teaching effect.It is worth noting that online teaching subverts the "same time,same place" teaching restrictions,and realizes great changes in teaching situation and mode.During the period of epidemic prevention and control,in order to ensure the teaching progress and quality,online teaching generally adopts the teaching method of"course platform as the main,network live broadcast platform as the auxiliary".Using the Internet,mobile network and other means to keep close contact with parents and students,put forward learning suggestions,create online classroom,carry out online teaching,organize teachers to seriously teach and research,reasonably adjust the effective interaction strategy between teachers and students,flexibly arrange the teaching content,guide students to develop autonomous learning,and ensure the effective and high quality of teaching effect.According to the characteristics of mathematics in grade one of senior high school,as well as the age characteristics and learning situation of students in grade one of senior high school,it has become the background and theme of this research to adopt gradually improved teacher-student interaction measures to maximize the learning effect.Based on the online education teaching theory,the author designs a better and more suitable effective teacher-student interaction strategy for students’ online learning,so as to further play the teaching advantages of online education and construct a series of teaching means and interaction strategies for online teaching in the post epidemic era.In this study,we mainly use the literature research method to study the online teaching and teacher-student online interaction strategy;through the questionnaire survey and interview method to students,teachers,and parents to carry out the questionnaire survey and interview to study the students’online learning achievements;through the use of multi round iterative design research to carry out three rounds of iterative experiment to carry out different in-depth research on teachers and students In this paper,the author introduces the teaching method of interactive means of online teaching,and studies the teaching effect to a certain extent.The author has carried out three rounds of iteration experiments which are gradually upgraded and enriched.In the first week,students only participated in the video video recording and broadcasting course learning of online cloud learning platform.Students learn knowledge points and typical examples of each chapter through online teaching platform,and teachers will give guidance to teachers if there are any problems;the next week,an online discussion group will be created to learn video video video from online learning cloud platform.Through carefully prepared video courseware and video courseware prepared by teachers before class and video courseware and typical examples,the teachers will learn video videos carefully before class The perfect curriculum structure arrangement,and then the online classroom teaching was realized through group discussion and cooperative learning.In the third week,on the original basis,the video connection or online live broadcast function of nail software was developed to assist the online cloud platform video recording and broadcasting class+group cooperation learning mode,which can meet the teaching mode of online video and broadcast courses.and And there are also online discussion groups of community model teaching.The research and assessment form of these weeks is the test results of online platform.In addition,teachers will conduct sampling investigation and interview on the basic situation of students through other communication software such as QQ,WeChat or nail chat box function,so as to further obtain students’ learning status and achievements.Based on the questionnaire and interview content,and the analysis and research of learning results,this paper puts forward the strategies and methods of effective interaction between teachers and students in online courses in post epidemic times from the aspects of learner research,preparation before online teaching,arrangement and implementation of teachers’ learning activities and some online teaching interaction means needed in online teaching process Suggestions.This study not only provides a wealth of theoretical guidance and practical experience for the application of online teaching in high school mathematics,but also puts forward strategies and suggestions for front-line teachers to improve the learning efficiency of traditional classroom,and paves the way for future research on the learning effect of online teaching. |
