Based On The Virtual Junior High School Chemistry Experiment "Double Case" Instructional Design

The quality education in national energetically advocate of today, double case teaching design become particularly important. This paper from the traditional teaching plan of the present situation of the case teaching, points to the double and of the double case in teaching on the basis of analysis, put forward the suitable for virtual experimental environment case teaching design for the new dual mode, and based on this specific case design.The first chapter from the topics of reason on why teaching junior high school chemistry virtual experiment "double case" design "in the title; followed by the elaboration of the pair of case teaching background to establish a dual case of instructional design research purposes. On this basis, from both theoretical and practical significance of the dual case teaching more systematic presentation and analysis.The second chapter is mainly the status of the traditional lesson plans analyzed, including the definition of the traditional lesson plans, as well as the value and role of the traditional lesson plans, analyze and summarize the current inadequacies of the traditional lesson plans exist on this basis, and forless than a solution.Chapter Ⅲ, point of view of teaching junior high school chemistry virtual experiment case, for the view from the concept of dual case, dual case, teaching status, and problems in the dual case teaching do the analysis and interpretation, and finally double case and virtual integrated model of the experiment.The fourth chapter focuses on a theoretical basis for the case of dual instruction and junior high school chemistry virtual experiment integration model, and showing through the specific process of how to implement the whole pattern.The fifth chapter is an example of design of the virtual experiment case teaching, which analyzes and expounded the importance of virtual chemistry experiments. And this article virtual experiment design theory and structure of the introduction of the system, and on this basis gives the specific example of virtual experimental case design and Evaluation of the effect of this paradigm.The sixth chapter is made to this article Conclusions and outlook, and put forward some ideas on future research directions.
