Research On Digital Experiment Teaching Based On The Core Lite Racy Of Chemistry

The five dimensions of core literacy in the discipline of chemistry are inheritance and development toward three dimensional goals including Macro identification and micro analysis,evidential reasoning and model cognition,changing ideas and balancing ideas,scientific inquiry and innovation consciousness,scientific attitude and social responsibility.Digital experiment,namely digital information system(DIS),is composed of sensors,data collectors and computers,has become a convenient,intuitive,real-time,accurate and visual new experimental technology.Compared with traditional experimental teaching method,the application of DIS in chemistry teaching is more effective to cultivate the core literacy of chemistry discipline of students.The aim of the study is to create a new teaching mode,apply digital experiment reasonably and effectively in middle school chemistry teaching,cultivate and improve core literacy of chemistry discipline in students,and enhance teaching efficiency of teachers.Under the guidance of the core literacy theory of chemistry,the high school chemistry digital experiment teaching research was carried out,and the following methods were used:literature research method,questionnaire survey method,teaching practice method,interview method,and oral report method.Firstly,a large number of related literatures and studies were retrieved and read.For one thing,to summarize the research status of "digital experiment","core literacy of chemical discipline" at home and abroad,for another,to clear the connotation of core literacy of chemical discipline and the basic theory required for this research.Secondly,in the form of questionnaire survey,the application of digital experiments in classroom teaching is understand.By analyzing the results of the survey,the factors that influence the application of digital experiments to classroom teaching is determined.Then,guided by discovery learning theory,constructivism theory,etc.,taking the teaching material content as the carrier,selecting appropriate teaching content,designing digital experiment cases based on the core literacy of chemistry disciplines,and carrying out a large number of teaching practices.After the case teaching,questionnaire survey was carried out on the students,to summarize the teaching effect of DIS in the development of chemical core literacy.Finally,through the overall analysis and evaluation of the case teaching effect,the preliminary research results of this thesis are obtained.The research found that the application of DIS in middle school chemistry teaching can not only reflect the integration of modern science and technology and chemistry classroom teaching,but also greatly promote learning enthusiasm of students.On one hand,DIS can contribute to the innovation of teachers'chemical knowledge and teaching methods for chemical experiments in middle schools,on the other hand,it can also promote changes in students'learning styles,effectively enhance students'learning ability,and better develop students'core literacy of chemical discipline.Meanwhile,by reflecting on the inadequacies of this study,subsequent investigators are suggested,and the contents of further research are put forward.The research has carried on the innovation to the middle school chemistry teaching mode,which can provide the reference for the front-line teachers.At the same time,it is conducive to the cultivation of core literacy of chemistry in students and plays a positive role in promoting the innovation and development of middle school chemistry education.
