Research And Design On Virtual Experimenta Teaching Platform Based Meta-Model

Virtual experimental teaching platform is the inevitable outcome of the education informationization development,it's the important technical support of establish modern education innovation system, and cultivating innovative talents. it can effectively improve the students' participation to begin, analysis and problem solving ability, etc.At present education resources under the present situation of unbalanced distribution, can improve experiment resources utilization level, fully share experimental teaching achievements and resources.First, studied the related theory of virtual experiment teaching, analyzed its development course and the relationship of virtual experiment, virtual experiment teaching and e-learning, Put forward the research framework of the virtual experimental teaching platform and its main contents;Second, analyzed the main elements and characteristics of the experimental components, constructed the formalization model of virtual experimental components, on this basis, designed the experimental component frame based on the meta-model and the management model of experiment components resources, built the experimental component libraries;Thirdly, based on the meta-model of experimental components, combining with requirements of virtual experiment teaching, established the connection and assembly model of experimental components, established a unified hierarchical structure of physical description and logical expression mechanism and experimental component connection-assembling rules, a deep research based on a per-template connection-assembly and self-organizing connection -assembly, established experimental resource management model;Fourthly, analyzed the virtual experimental teaching platform for interactive objects, interactive mode and the components of teaching environment, studied the structure design of virtual experimental teaching platform and design principles, puts forward an architecture of SOA, analyzed the business process, designed service bus and service unitFinally, designed and realized the preliminary examples of the virtual experimental teaching platform.Future, the research will be focused on the standard rules and evaluation system of virtual experimental teaching platform, the multidimensional display, interaction of experimental components the resources sharing with heterogeneous platform, to improve the efficiency.
