The Design And Application Of Middle School Chemistry Course Online Experiment Platform

The middle school chemistry course is the core curriculum of middle school education,and it is one of the compulsory subjects for college entrance examinations for science and engineering students,which occupies a very important position in the middle school science education.How to improve the teaching effect of the chemistry curriculum is a major issue for teachers.There have been many reforms to the chemistry curriculum but the effect is not very good.This thesis draws on the application of information technology in chemistry teaching,and uses information technology to construct an on-line experiment platform for middle school chemistry courses to realize the reproduction of chemical experiment environment,effectively improve students' interest in learning,enhance students' learning experience,and improve teaching and learning effectiveness.We use database technology,Java language and other software to develop an online experimental platform for middle school chemistry courses that supports the review and experimental reproduction of chemical experiment courses.The system platform adopts an object-oriented analysis and design method.The back-end database adopts the MS SQL Server database system.The language tools such as Html and Java are comprehensively used.The Struts framework,Spring framework,and Hibernate framework are used for code development.According to the principle of software engineering,we designed and implemented the basic functions of the middle school chemistry course online experiment platform.The middle school chemistry course online experiment platform realizes the contents including synchronous experiment video,maker test,teacher lecture hall,teacher teaching and research,and competition event management.Synchronous experiment video realizes the publish of synchronous experiment video,the viewing of synchronous experiment video download record,the synchronous experiment video browse record,the viewing of synchronous experiment video collection,the viewing of my synchronous experiment video,and the synchronous experiment video comment;maker experiment achieves the release of maker experiment,the viewing of Maker experiment download record,the maker experiment browse record,the viewing of maker experiment collection,the viewing of my maker experiment,and the maker experiment comment;teacher lecture hall realizes the release of teacher lectures,the viewing of teacher lecture halls,the review records of teacher lecture halls,the viewing of teacher lecture hall collections,the viewing of my teacher lecture halls,and the comment on teacher lecture halls;teacher teaching and research achieves the experimental library download,the viewing of experimental library,the view of experimental library details,the publish of documents,the viewing of my documents;the competition activities realizes the uploading of competition events,the management of competition activity rules,the viewing of competition activities,the search for competition activities,and the viewing of competition activities.Through the use of information technology to change the teaching model,to further strengthen the integration of online and offline information-based teaching design,and to improve the theoretical teaching of chemistry courses.Through continuous exploration in teaching practice and use among some students,it was found that the platform can effectively increase students' interest in learning chemistry courses and bring changes in students' learning styles.The application of the system will inevitably bring model innovation and quality improvement of chemistry theory and experimental teaching.This also has a good reference for other science courses.
