Research Of Ill-structured Virtual Experiment Design

The learning based on the ill-structured experiment has great promotion on innovative thinking and independent analysis, problem-solving abilities of learner. How to design a ill-structured virtual experiment in terms of functional structure and teaching scientifically and rationally is an important topic of virtual experiment system comprehensive development ,also an important precondition that virtual experiment really serve for experimental teaching. Therefore,it has a considerable significance to explore the methods of design an ill-structured virtual experiments, guide the developing practice of ill-structured virtual experiments,making a better play to its advantages of virtual experiments,assisting the traditional experiment teaching.In the recent years,the research of how to build the function of virtual experiment system has increased , and researches in theory and practice of independent study in the network environment have got some achievements. It has very important influence on the innovative thinking and independent analysis, problem-solving abilities of learner based on the ill-structured virtual experiment,however,the study of design patterns of the ill-structured virtual experiment is not enough.In view of this, in order to extract a theoretical basis and a direct reference to the design patterns of ill-structured virtual experiment from ill-structured domain knowledge,first, this paper analyses the instructional design model of ill-structured domain knowledge,and analyses of the Cognitive Flexibility Theory which developed on the ill-structured domain knowledge, and studies the instructional design model based on learn to build a instructional design model of ill-structured virtual experiment, for solving the problem about that the construction of virtual experiment system is not comprehensive enough, the design patterns of ill-structured virtual experiment is not immature, etc. To make virtual experiment serve for experimental teaching better.On the other hand, Analysis the main elements of the design patterns of ill-structured virtual experiment, including instructional design model, structure and function of design patterns, technical solutions design, etc. And put these design patterns in practice. The details of every part are as follows:The first part of this paper primarily introduced the background of the research, analyzed the present research situation about the theory and practice of ill-structured domain knowledge and virtual experiment,and summarized the core problem of the design of ill-structured virtual experiment. Based on these, this chapter proposed the design concept and research supposition of the design of ill-structured virtual experiment,and described the research contents and significance of this paper.The second part mainly analyzed research the ill-structured domain knowledge which has a direct reference to the research,and defined range of ill-structured virtual experiment.The research of the Cognitive Flexibility Theory and the instructional design model based on learn is a solid foundation for this paper.The third part analyzed the learning features,learning process,principles of design and development based on ill-structured virtual experiment,and discussed the design elements and key issues of ill-structured virtual experimental,proposed the instructional design model, structure and function of design patterns,technology solutions and development process.The forth part validated the design model which proposed in the third part,developed a practical case,discussed main ideas of the creation of experimental conditions, evaluation feedback module and especially independent experimental design module,and reflected the design model in practice.The last part summarized main tasks and weaknesses of this research, as well as the directions of further research.The design of ill-structured virtual experiment is necessary in building a virtual experiment system structure. It can help learners to improve ability of innovation, analyse and solving problems by self-study in the learning environment based on ill-structured virtual experiment. How to design comprehensivly ill-structured virtual experiment is still a difficult problem in virtual experiment research at the present time.We hope that the achievement of this thesis can use the little to get the big,furthermore, we hope that the research can provide valuable reference for further research and exploration of related problems in virtual experiment,thereby promoting the design theory, design patterns and development practices of ill-structured virtual experiment to develop continuously.
