The Design And Implementation Of Intelligent Guidance And Scoring System For Virtual Experiments In Primary And Secondary Schools

Virtual experiment is an important part of online education.By carrying out virtual experiments,students can fully interact with the experimental objects,flexibly design all aspects of the experiment,and quickly verify the independently designed experimental scheme.When there are many participants in the experiment,the time and space of the experiment are highly dispersed,so it is difficult for teachers to provide real-time experimental guidance,and the workload of correcting the experimental results manually is also very large,therefore,it is necessary to study intelligent guidance and scoring techniques to provide better support for teaching.This article first analyzes the original guidance and scoring functions in the virtual simulation experiment system,explores the shortcomings in the prototype system,and investigates the problems encountered in the current use process through investigation.This article separates the guidance and scoring functions from the original system.Through requirements analysis,summary design,detailed design,system implementation and testing,the overall architecture of the system is designed,the design ideas and implementation methods of each layer of the system are described.Finally,the intelligent guidance and scoring system of virtual experiment in primary and secondary schools was developed.In this paper,the design of experiment script format is combined with relevant national standards,which expands the setting range of scoring points,so that the guidance and scoring can be oriented to the whole process of the experiment.At the same time,this article also carried out the revision work of the script data based on the graph model,which overcomes the strong dependence of the original guidance and scoring rules on the name of the experimental equipment.The system allows teachers to formulate guidelines and scoring rules in virtual experiment scenarios,improving the efficiency of rule making.Combining with related technologies in the field of natural language processing,this paper implements the scoring of the experiment report,so that the intelligent scoring covers the whole process of the experiment.The system described in this article is developed based on the SSM open source framework,combined with the related technology of Drools rule engine.The test and verification part shows that the system can meet the actual teaching needs and achieved good results.
