Research On The Teaching Model Of Chemical Virtual Experiment Based On Internet

Virtual experiment which relies on computer,multimedia,virtual simulation technology,creates a high degree of simulation experimental environment and objects to complete experimental operation process in the computer.Using the Internet,it can break the limit of space and time,compensate for the disadvantages of traditional experimental teaching and eventually meet the requirements of new curriculum standard.But it failed to achieve the desired advantages for lack of a scientific operation mode.Therefore,the construction of efficient virtual experimental teaching model has become a hot topic for educators.Firstly,this paper lists the principles of virtual chemistry experimental teaching based on the "Internet +",and put forward the design ideas about chemical virtual experimental teaching based on the Internet.Secondly,it investigates the problems such as the students’ recognition degree,adaptability to virtual experiment,the information technology level and the information teaching concept of the teachers from high schools in Guangdong province which draw the feasibility of this study.Next,it builds "234" virtual experimental teaching model based on the Internet,and design a virtual experimental platform to support the implementation of this teaching model.The highlight of this model is that it can run through from class to class,and combine the experimental inquiry,cooperation and communication,problem solving,exercises,and evaluation as a whole.This study designs and analyzes respectively one gas preparation experiment,one exploratory experiment and one micro-chemical experiment.Finally,the experimental teaching method is used to test the two classes.The result shows that the teaching mode improves the quality of experimental teaching and is conducive to cultivating students’ independent inquiry spirit and innovative their practice ability.It also meets the requirements of the new curriculum standard.
