| The chemical virtual simulation experiment is based on the virtual simulation technology,and combines multimedia technology,graphics and image science and professional theoretical knowledge to construct the experimental simulation training system,which is mainly presented in the form of animated video in computer software.It is the product of the deep fusion of chemistry and information technology.It can make up for the deficiency of the traditional experiment teaching,meet the requirements of the new curriculum standard,and enhance the students' interest in learning chemistry.Therefore,it is of great significance to construct the chemical virtual simulation experiment database.Firstly,the present situation of chemical experimental teaching in senior high schools in Guangxi is investigated by questionnaire.It mainly includes "high school students' emotional attitude and problems encountered in chemical experiment learning","students' emotional attitude towards chemistry experiment teaching",and "equipment conditions of middle school chemistry laboratory".In the form of interviews,the information technology level of students and teachers and their views on chemical virtual simulation experiments are interviewed.It is concluded that the research of chemical virtual simulation experiment is of significance.Secondly,the content of chemistry experiment in senior high school is analyzed and reintegrated into four categories,namely,basic experiment,representation experiment,innovation experiment,comprehensive experiment,and the corresponding virtual simulation experiment module.The characteristics and classification are explained accordingly.Finally,by analyzing the content of chemistry experiment of compulsory subject 1 in the version 1,the laboratory preparation of chlorine gas in the second section of Unit 4 is selected as the teaching case,and the comparative experimental teaching method is used to teach in two classes of high school one in the practice unit.Finally,the effect of virtual simulation experiment in chemistry experiment teaching is analyzed,and it is concluded that virtual simulation experiment has certain practicability for chemistry experiment teaching in middle school.It is feasible to improve learning interest and assist students to master chemistry experiment knowledge.It is also in line with the requirements of cultivating the core accomplishment of chemistry subject.It is well liked by senior high school students and recognized by teachers.It has a good prospect of development and application. |
