Practical Research On Informatization Of High School Chemistry Exercises And Accurate Teaching

Information technology has penetrated into various industries and fields,played a role that can not be ignored,and gradually become the leader in addition to people.Therefore,its integration with education is also the general trend.Nowadays,we have the conditions to make the construction and improvement of information infrastructure and hardware,but many front-line educators are not willing to apply it to the old teaching mode,which makes the promotion of information hindered.Based on the above background,the author thinks that the teaching reform of education informatization should be gradual,without changing the original teaching habits and classroom behavior of teachers,the new mode of high school chemistry exercise exercise is derived by using informatization,and the personalized and autonomous precision teaching is launched under the tracking and analysis of big data.Firstly,this paper analyzes the necessity of using information technology to change the practice mode of high school chemistry exercises from the current situation of education and teaching in order to achieve accurate teaching;Then,it explains the theory,equipment introduction and process design of "exercise informatization +precision teaching";On the basis of the above,the design of real exercise lesson is carried out,with the new teaching case analysis "iron and its compounds",review lesson case analysis "comprehensive application of chemical reaction principle",exercise lesson case analysis "hundred school alliance new college entrance examination chemical quality test" as the research samples,to realize the great convenience of data and MOOCS in classroom teaching;Finally,some teachers and students of the school use the method of interview and questionnaire survey to sort out the advantages and disadvantages of "exercise informatization + precision teaching",and put forward their own thinking and suggestions on this content.Practice shows that the informatization of high school chemistry exercises achieves the goal of precision teaching through the use of big data.For schools,they should share the resources of famous schools,improve the level of running schools,and gradually form their own characteristic teaching resources and information-based school-based curriculum;For educators,it reduces the burden of teaching,data analysis makes the diagnosis of learning situation more scientific,effective and specific,and provides theoretical support for the realization of accurate teaching;For students,the accumulation of exercise data over the past three years has formed their own learning situation diagnosis network diagram,which clearly shows the stability and weakness of knowledge,so senior three review will be very targeted.To sum up,"exercise practice informatization + precision teaching" really plays the role of informatization teaching,improves teaching efficiency and cultivates students’ autonomous learning ability on the premise of not affecting teachers’ routine teaching,which is a strong evidence of the development of informatization education practice.
