Research On Chemistry Digital Experiment Teaching In Junior Middle School

Digital experiment was born in the Internet age.As a technical means of "Internet + education",it is entering the field of vision of the majority of researchers.Scientific and technological progress has built a solid support for educational innovation,and digital experiments have the opportunity to enter the classroom and make the classroom shine.This study comprehensively uses a variety of research methods,such as literature research,questionnaire survey,observation,experimental investigation and interviews,to make a detailed research on the application of digital experiments in junior high school chemistry teaching.To a certain extent,this research can make digital experiment technology be supplemented in experiment innovation and classroom application.Under the guidance of Constructivism Theory,humanism theory and multiple intelligence theory,this research analyzes the development process of digital experiments at home and abroad,traces the development process of digital experiments at home and abroad,and sorts out the closely related traditional experiments.Be able to design the content of digital experiments,redesign the experiment purpose,experiment principle,experiment plan and evaluation,and improve and innovate the original experiment on a reasonable basis.A total of 20 innovative experiments that can be carried out with digital experimental technology have been sorted out,and 4 digital experimental cases have been designed from the aspects of visualization of experimental phenomena,visualization of reaction mechanisms,visualization of reaction processes,and quantification of qualitative experiments,and applied the designed experiments in the classroom teaching,teaching practice was carried out in more than three classes of junior high school.This research uses the classroom observation method,analyzes students' attitudes towards handheld technology entering the classroom,understands the difficulties in the implementation of digital experiments,and proposes targeted solutions.This research selects the real questions of the senior high school entrance examination in recent years,finds out the exercises that involved digital experiments,analyzes which aspects of the ability of the students were tested,and provides some improved experience for the follow-up researchers.This research clarifies the position of digital experiment in junior high school chemistry teaching,and proves that digital experiment can be introduced into junior high school chemistry teaching in a planned way,which can effectively supplement traditional experimental teaching.The research of this project believes that it is possible to carry out digital experimental teaching pilots in schools in developed areas,or to carry out interest experiments in the second classroom,so that the comprehensive literacy of students and the professional literacy of teachers can be improved to a certain extent.Studies have shown that the application and promotion of digital experiments also requires the collaboration of instrument manufacturers,front-line teaching teachers,and teaching and research staff at all levels in order to truly blossom and achieve the deep integration of information technology and chemistry teaching.
