| With the continuous advancement of education information process and the continuous development of virtual simulation technology,the advantage of "Internet + education" is increasingly prominent,which has a comprehensive and far-reaching influence on basic education teaching of our country.Physics is a natural science based on experiment.The discovery and establishment of physical principles and laws are based on experiment.The development of information technology makes the form of physical experiment more diversified and flexible.In the Opinions on Strengthening and Improving Experimental Teaching in primary and secondary Schools issued by the Ministry of Education in 2019,it was pointed out that "cutting-edge technologies should be continuously integrated into experimental teaching".At present,the integration of virtual simulation experiment into experimental teaching is a hot issue that most researchers pay attention to.However,whether virtual simulation experiment teaching can effectively improve the physical learning effect of middle school students has not been proved.This research is mainly carried out from the following aspects:Firstly,the literature research method and the measurement research method are used to sort out the research status of virtual simulation experiments in China.Taking the literature related to the virtual simulation experiment teaching of CNKI database as the research object,starting from the annual publication volume,subject field distribution,journal and keyword co-occurrence,EXCEL and Cite Space software are used to conduct visual analysis,analyze the current research hotspots from the data results,and predict the future research trends.Then,the meta-analysis method is used to systematically analyze the empirical research literature on the impact of virtual simulation experiments on students’ learning effect in China,and quantitatively study the effect values in the literature,and explore the regulatory variables affecting students’ learning effect.It is found that the four dimensions of education stage,experiment cycle,experimental method and different software have different degrees of positive impact on students’ learning effect.Finally,according to the results of the meta-analysis,the section of "Electric field intensity" is designed.Combined with the teaching research status of virtual simulation experiment,the paper proposes targeted promotion strategies and suggestions from the perspectives of society,school and teachers.The contents and achievements of the whole research process are summarized,and the shortcomings of literature research are reflected and prospected. |
