| Learned through virtual experiment in teaching practice in the teaching of The chemical is anexperiment-based science, so the experimental teaching has a very important position in ChemistryTeaching.The new curriculum reform in2003, put the scientific literacy of students and the overall qualityof training on a more important position.But today’s high school chemistry experiment teaching there are alot of serious problems, in this stage, the attention of the experimental teaching and experimental teachingmethods single form a contradiction, so has applied to experimental teaching is deep and importantmeaning.Information technology in the experimental teaching has been part of the application, virtualexperiments based on application of computer technology as the core, combined with the virtual realitytechnology, simulation technology, computer graphics technology to generate realistic experimentalsituations, the user in the context related use equipment operate virtual instruments and devices to completethe experiment.The virtual experimental part of the application has received a certain effect, in order tolearn more about the application of virtual experiment in teaching high school chemistry experiment, we dothe following aspects of the work.1.Secondary school teachers and students in some areas of Henan Province, a survey and interviews,we learned that87.56%of the students expressed a keen interest in learning chemistry experiment course,and86.67%of the students of the great interest in chemical experiments, only15.11%%of students thinkchemistry experiment fraught with danger and should avoid contact. But in today’s high school chemistryteaching,47.11%of the students in the high stage of no chemical experiments,45.78%of the studentsoccasionally done chemistry experiments. Currently mainly involved in the experiment teaching methodsor teacher demonstration experiments, but even still12.00percent of the teachers have not conducted ademonstration experiment, but to explain the experimental. At the same time, up to97.78%of the studentsthink chemistry experiments for studying chemistry help,90.67%of the students said that schoolexperimental conditions do not allow the case to use experimental video and analog animation tounderstand the experimental. And students have great interest in learning for metallic and non-metallicnature of the experiment and the flame reaction experiments. For teachers in the experimental teachingsuggestions should focus on experiments to do more chemistry experiments, if the conditions do not permit should allow students to learn more about the experiment.2.Through the sample survey,35.89%of the students said the school offers computer courses,76.89%of the students said that the classrooms are equipped with multimedia teaching equipment, and78.22%ofthe students compared to traditional applications of information technology and virtual experiment inteaching teaching prefer multimedia teaching,77.78%of the students believe that multimedia teachingapproach to the promotion of chemical interest in learning, teaching high school subjects,60.44%of thestudents believe that the physical and chemical appropriateness of using multimedia teaching,76.44%ofthe students are more like video the animation multimedia teaching. Up to94.22%of the students have helpfor a better understanding of the experimental use of information technology demonstration experiments.But today’s high school chemistry teaching,70.67%of the teachers never used multimedia teachingmultimedia player or demonstration experiment,72.00%of the teachers did not use in teaching. Most of thestudents said the use of information technology experimental teaching, at the same time hope itself toparticipate, to change the watch is demonstrated with the status quo, mainly to independent experimentaloperation.3.high school chemistry experiment: the experimental group,68.89%of the students to master thebasics in terms of knowledge mastered54.76%mastery of the basic knowledge and did not use the doctrineof IT visible virtual experiments for experimental teaching for students to master the basics with somesuccess. Understanding of the content of the experiment, the students of the experimental group71.11%understanding of the experimental and the control group,30.95%of the students understand andexperimental part, by contrast, virtual experiments for experimental teaching students understand andexperiments related content has a large effect.20.00%of the students in the experimental operation skillsimproved experimental operation skills improve, the experimental group, control group19.05%of thestudents in the experimental operation skills improved, from the experimental operation in terms of the useof virtual experiments in experimental teaching The effect is not ideal. |
