Research On The Teaching Practice Of Primary School Science Experiments Based On Virtual Experiments

Primary school science is a highly experimental subject,and the science experiment section has a significant impact on students in the enlightenment stage.The "Compulsory Education Primary School Science Curriculum Standards"（2017 edition）（hereinafter referred to as the curriculum standards）advocates teachers to use textbooks creatively in actual education and teaching,carry out scientific inquiry activities on the basis of experiments,and pay attention to students’ scientific inquiry ability and scientific innovation spirit The cultivation of students lays the necessary foundation for the cultivation of students’ scientific literacy.Traditional experimental teaching is in an important period of transition to inquiry teaching.Due to various limitations,traditional physical experiments can no longer support the development of elementary school science experiment teaching.Therefore,the application of information technology to elementary school science experiment teaching is very important for curriculum reform.It is of great significance,and information technology has already been used in experimental teaching.Virtual experiments,due to their high degree of sharing,repeatability,and high safety factor,can strongly support the development of scientific inquiry activities.It is an exploratory experiment.It has contributed to the development of teaching,so it is increasingly becoming a hot field of experimental teaching research under the current educational background.This research mainly adopts literature research method,questionnaire survey method,quasi-experimental method,interview method and other methods.It relies on the virtual experimental teaching service system for primary and secondary schools of the Central Audio-visual Education Museum（hereinafter referred to as the central library system）,and aims at the affiliated experiment of Minjiang Normal College In the third grade of elementary school students,select the most representative virtual experiment case of "the cause of wind",and explore the theoretical value and practical significance of applying virtual experiment in elementary school science experiment teaching through the teaching method of "combination of virtuality and reality".The research is divided into five parts: The first part introduces the research background,core concepts,research ideas,research innovations,and the main content and structure of the paper;the second part introduces the current research status and related theoretical foundations at home and abroad;The three parts respectively introduce elementary school science courses,the analysis of the characteristics of elementary school students and science teachers,and the principles and cases of virtual experiment application in teaching;the fourth part compares the preparation work,teaching design,teaching process and teaching results of virtual experiment teaching cases Explained in detail and analysis,and evaluated the virtual experiment resources based on the questionnaires filled out by teachers and students about the use of virtual experiments and teacher interview evaluation content;the fifth part is the summary of this research,analysis of deficiencies and future prospects.The results of this research show that the application of virtual experiments in elementary school science experiment teaching is feasible and effective,whether it is for the cultivation of students’ practical ability and innovation ability or the improvement of teachers’ teaching ability and classroom efficiency.Virtual experiments are used as a teaching aid Means,applying it to elementary school science experiment teaching is a supplement to traditional experiment teaching.It is hoped that this research will provide some reference for the future education and teaching of elementary science teachers.
