A Survey On The Feasibility Of The Current Online Chemistry Teaching In Senior High Schools Can Replace Offline Teaching

With the constant development of multimedia technology and the unremitting deepening of education modernization,the integration of the network and education has become more and more closely.The relevant governments and departments also attach great importance to the combination of network and teaching.At the beginning of 2020,the COVID-19 occurred.Because of it,the complete online teaching in senior high school has been able to carry out large-scale and long-term teaching practice.Based on the author’s personal online teaching experience,combined with references in the forum of S206,a teacher training program organized by Yongzhou Academy of education and Sciences,35 chemistry teachers from three grades of Yongzhou NO.4 middle school were consulted,and issued questionnaire to three grade of Yongzhou fourth middle school,and randomly selected some students for interviews.The advantages and disadvantages of online teaching and offline teaching in high school chemistry during the epidemic period were investigated from the perspectives of teachers and students.The purpose of this paper is to study the feasibility of online teaching completely replacing offline teaching,and also to provide reference for the follow-up high school chemistry teachers who use online teaching.The results show that,for teachers,the effect of chemistry online teaching is far worse than offline teaching,and there are many disadvantages.There are also advantages of online teaching,but these advantages can be ignored compared with disadvantages.For students,online teaching gets rid of the limitation of time and space,it also has obvious advantages and many disadvantages.However,compared with teachers,students have a higher degree of acceptance of Chemistry Online Teaching and have more sense of identity.If the shortcomings of chemistry online teaching are improved and avoided,we believe that online teaching can play a better role in chemistry teaching.It can play a more positive role in arousing students’ interest in learning and cultivating students’ autonomous learning ability.Combining the views of teachers and students on online teaching,we can draw the conclusion that online teaching is not feasible in high school chemistry teaching at present.Although the application potential of online teaching mode has Great potential,but in order to make better use of it,there are still many problems needs to be solved.For example,the online teaching equipment and network facilities are upgraded.On the one hand,the traditional classroom teaching is conducive to the interaction and emotional communication between teachers and students,which is convenient for standardized management.On the other hand,Simple online teaching does not work,but it can’t effectively manage students and other shortcomings can be solved by offline teaching.Therefore,the best way to get along with online teaching and offline teaching is to achieve each other rather than replace each other.The future teaching mode must be the combination of online teaching and offline teaching,that is,the Blending Learning which is suitable for local conditions and different people.In order to meet the trend of educational information and improve the teaching quality in an all-round way.Then,based on references and my own teaching experience,I have proposed the applicable ideas of online and offline hybrid teaching mode in senior high school chemistry teaching.Including:(1)cultivating students’ independent learning ability and self-discipline ability;(2)establishing a perfect education information platform;(3)Cultivate students’ habit of using online learning;(4)strengthen teachers’ ability to apply online and offline hybrid teaching models;(5)offline teaching activities should consolidate and transform online knowledge acquisition.Finally,In conclusion,I have analyzed the specific operation of the online and offline mixed teaching mode in the application of high school chemistry teaching,and proposed a general mode for applying the online and offline mixed teaching mode to high school chemistry teaching,It explains in detail how to set up the teaching process with experiment as the center as possible in the course,optimize and limit the students’ learning terminals and network,and use information technology to make the offline classroom more vivid and more interesting.And uses a certain amount of substance to concentrate the solution and the first class of chemical energy and electric energy.these lessons as an example have shown the feasible application method of hybrid teaching mode at this stage.The content of chemical reaction and electric energy of online and offline mixed teaching mode is applied to teaching practice.The practical effect of the new model is studied from the two dimensions of achievement and interview by comparing the teaching mode.The results show that the online and offline mixed teaching mode has certain effect,and the students’ achievement can be improved.
