Based On The Vrml Virtual Experimental Design Of The High School Physics

Today,as the science technology developing rapidly,the modern information technology which takes the computer technology,network technology and communication technology as cores has been widely used in the field of education,and led to profound changes from the concept,content,methods,means to model the process of education.Virtual experiments as a means of advanced information technology are gradually introduced into the field of education and enriched the content of the experimental teaching and improved the theoretical system of experimental teaching.On the base of studying at physics experiments in secondary school,the author analyzes the necessity of developing virtual physics experiments,makes a thorough inquiry to the technology which is used to explore virtual experiment,designs and implements VRML-based virtual physics experiments,and researches the six key technology of this experiment system in depth. On the following the guidance of new curriculum,the system follows the model of instructional design,demonstrates the principles,steps,objectives,equipment,processes and results of operations and so on.Virtual experiments,which have the characteristics of the context of technology implementation,high interactivity and immersion of learners,will help enhance interest in learning,learning efficiency.And it makes up for the shortcomings of traditional experimental teaching to a certain extent.This article includes seven chapters,in the first chapter,on the base of questionnaire survey, the author analyzes current problems in the middle school teaching of physics experiment,and points out the corresponding solution and the necessity of physics experiments;In the second chapter,the author analyzes the concept,type,characteristics and history of virtual experiment, researches for a variety of technologies including 3D MAX,VRML,JAVA,etc.for exploiting virtual experiment,and puts forwards the opinion of integrating these technologies to create virtual physics experiments;In the third chapter,I analyzes the virtual school physics experiments in total,and the characteristics of virtual experiment system,establishes the projects to pilot,and expounds functional requirements and performance requirements of physical virtual experiment system in secondary school;In chapterⅣ,on the base of the analysis of needs, combining with network characteristics and needs of students,the author designs a practical experimental system,and takes the alternator virtual experiment for an example;In the fifth chapter,the author introduces the module and the process of physical virtual experiment system taking the alternator virtual experiment as an example to introduce,then the author introduces the key technologies for exploiting physical virtual experiments system;In sixth chapter,At the same time,the author develops two sets of thematic web for users integrating all physical virtual experiment which have been exploited,and discussion the prospects of the physics virtual experiment of secondary school;In the seventh chapter the author takes the summary and the outlook on the job.
