The Research Of The Diagnosis Of Virtual High School Chemistry Experiment Operation

It is a new time, in which new technologies have been used in the education market more and more, so virtual laboratory has much feasibility of being realized in high school chemical education. Because only the really practical products are the good ones, but the speculative products are just the ones which are in new technology name only, and they have no the ability to be established in China's education software market for long time in this competitive era, so if the good education software can succeed, the important point is that if the developers can satisfy the users' need. In this case, The Research of The Diagnosis of Virtual High School Chemistry Experiment Operation began, and it has the idea of treating the users as the core, providing personalized service, perfecting the virtual chemistry lab, in order to overcome restrictions of time, room and equipments, for reaching the goal of making users can train chemical experiment courses at home, which could mobilize the initiative of users and make a much better learning result.This research preinstalls the virtual chemistry lab of NENU Ideal as the software foundation, and uses the diagnosis method based on model as the theoretical basis, starts from the typical high school chemical experiments, analyses several blue prints, and at last uses the Deterninistic Finite Automata (DFA) to do the research, with which establishes 3 state library and 2 operation library. The key point of this research is that choosing the DFA to do the research, because this method could effectively reflect the experiment contents and experimental process, and can reflect the properties of the wrong operations.The run of DFA depends on the skips of states at every time points, for describing the skips, the 3 state library and 2 operation library are established, which are the base of the continuing research.
