| In recent years,with the rapid development of new and high technology,network education has made great progress.Due to the teaching characteristics of the breakthrough of time and space,online experiment has become one of the most important teaching links to achieve the goal of cultivating students' practical innovation ability.In addition,the online experiment with its digital,easy maintenance,and can be used for large-scale students to recycle,to record the student's behavior data and other advantages,is highly concerned by the academic research and the construction of colleges and universities.But at present,the research of online experiment resources,more attention to the function design and implementation of online experimental curriculum resources,application technology innovation,limited to the research of local static module,ignore the analysis of the dynamic development and change on the whole level,so resources can not be updated in a timely manner to meet the needs of the learners.From the perspective of ecology,the ecological system of the online experiment curriculum resources is analyzed by this paper,which is formed of ecological subject including teachers,learners,curriculum resources,and external environment.Teachers and learners have a direct impact on curriculum resources,the external environment influences the curriculum resources indirectly through influencing the subjective consciousness of the teachers and learners.Opening the function and structure of the system to promote the information exchange between the ecological subjects becomes the key of the dynamic balance of the online experiment course resources.Through the investigation found that there are many realistic problems in the online experimental study,such as the learning time is scattered,the basic difference is big and the lack of communication,etc.According to practical problems and needs,open the function structure from the four strategies of personalized,situational,co construction and dynamic balance,and construct the ecological construction model which based on three cycle of content to the appropriate evolution,data to the classical evolution,recommendation to the exact evolution.The concrete measures to realize ecological construction of online experiment including experimental fragmentation processing,navigation,knowledge point identification,data editing,recommendation,evolution mechanism,etc.Taking the router experiment of a university virtual physical system platform as an example,the prototype is designed and implemented in this paper.After the experimental learning process of the prototype of the curriculum resources,contrast development and change of prototype before and after experiment:the experimental prototype is added experimental debris identification,experimental data etc.It is verified that the research of online experiment course resources ecological construction has certain effect. |
