Research Of The Construction Of Question Context In The Virtual Demonstration Experiment

Virtual demonstration experiment has been widely applied to the experimental teaching, how to design virtual demonstration experiment has become the core issue in affecting teaching effect of the virtual demonstration experiment. Therefore,it is important for question context to provide meaningful learning related to a deeper understanding.Current domestic and international research on the virtual experiment has yielded results,but more researches focus on research and development of virtual experiments, discussions about question context stay in PBL model,the research about how to use virtual reality technology to present the research problem situations is less than other researches.In this view,the researches and the summary are made about virtual experiments and question context at home and abroad,focused on the phenomenon presentation of virtual demonstration experiment and the function of pile which originated in "the technology-central" design concept are found. However, developing the importance of problem solving is important in the new curriculum reform, question awareness training is a prerequisite to improve the ability.The research makes this into a starting point of this study.It puts the " question context" into the process of developing the virtual demonstration experiments, effectively integrates the use of virtual reality technology and web development technology, creates physical and psychological aspects of context, and further enriches the elements of the question context to satisfy the learners` needs,and so as to promote the comprehensive building of knowledge and personal knowledge growth.The paper structure and the details of the various chapters are as follows:The first chapter briefly describes the background of the problem, analyzes research status of question context and virtual demonstration experiments . On this basis, it puts the " question context " design concept into the design of the virtual demonstration experiments; Refering on the research methodology of soft systems thinking, it puts this study into three stages: preliminary work, question context and case development,so the work provides a practical and strategic guidelines .The second chapter defines and analyzes the content of the question context, reveals the relationship about the problem, the question context and the virtual demonstration experiment. It provides specific guidance and implications for question context through the combination of situated cognition theory and human information processing theory.In the third chapter, the general principles are extracted based on the characteristics of the experimental teaching and the psychological levels of students. The three elements of film and television drama and elements of constructivist learning environment are borrowed, and development process in the virtual demonstration experiment is discussed.The forth chapter talks about the design and development of specific cases.The general principles of question context are followed and the specificity of the experiments is combined. It carefully analyses from the formation of the question to solving and reflecting. The virtual demonstration experiment is developed which follows with the MVC development model, uses the Jsp + Stripes + Flash technology and tests the stress of concurrent requests with ApacheBench testing tool,and evaluates the effects of the virtual experiment.The last chapter is about the summary and outlook. it points the shortcomings. Through virtual reality technology ,showing the question context is necessary in building virtual demonstration experiments. The learners will deeply comprehend the contained knowledge by observing the phenomenon of virtual experiments and the plot;The learners understand wide knowledge from observing the phenomenon of virtual experiments and the plot;The learners obtains the understanding of learning content from the significance level. There is the comprehensive and systematic description in the paper from theory and practice about the question context of the virtual demonstration experiments in order to extend the application of the virtual demonstration experiments as well as expand PBL teaching support.
