Digital Experiment Is Applied To The Case Integration And Practical Research Of Junior Middle School Chemistry Teaching

Digital experiments are based on computer real-time data acquisition and computer modeling and image analysis technologies.Digital experiments are the product of the combination of information technology and modern teaching concepts.They are introduced into middle school chemistry experiments teaching to improve the efficiency of traditional education and teaching.Meanwhile,it encourages the innovation of experimental teaching,provides the necessary conditions for research-based experimental teaching,and promotes the modernization of middle school chemistry experimental teaching.At present,the Ministry of Education is vigorously advancing the process of informatization and modernization of education,and attaches great importance to the improvement of student experiments and information technology-related scientific literacy in the compulsory education stage.A series of equipment requirements and practical activity recommendations for digital inquiry experiments are listed in the inquiry theme.In terms of practical implementation,many middle schools have introduced digital experimental equipment.Middle schools in relatively developed regions have successively built digital laboratories,but digital experiments have not yet been fully applied in the daily teaching of middle school chemistry,especially junior high school chemistry.As a result,most teachers are struggling to design and carry out digital experiment activities suitable for application in junior high school chemistry teaching.Therefore,the author hopes to provide relevant reference for frontline chemistry teachers through this research.This research focuses on the teaching application of digital experiments in junior high school chemistry.The research contents include:(1)understanding the characteristics and development process of digital experiments;(2)based on junior high school chemistry curriculum standards,junior high school chemistry teaching equipment configuration standards,existing literature and The human education version of the textbook integrates 74 digital experiments and inquiry activities that can be applied to junior high school chemistry teaching;(3)The four teaching links of introducing new lessons,learning new knowledge,consolidating and improving,and applying extensions are used as application scenarios and designed for junior high schools Digital experiment cases of chemistry teaching applications;(4)Conductresearch on teaching practice,investigate teaching effects,and make suggestions for teaching applications of digitized experiments in middle school chemistry.The research draws the following conclusions:(1)It is feasible and necessary to apply digital experiments to the case integration of junior middle school chemistry teaching.(2)Digital experiments can be used in different teaching links.Four teaching links: introducing new lessons,learning new knowledge,consolidating promotion,and expanding applications can be used as teaching scenarios to integrate and design digital experiments in junior high school chemistry.(3)The digital experiment designed according to the teaching link is practical in junior middle school chemistry teaching.Finally,the paper puts forward suggestions on the application of digital experiments in junior middle school chemistry teaching,and reflects on the deficiencies of research.
