Design Of Simulation Experiments Under "Internet Plus"

Education informationization promotes educational modernization.In March 2015,Premier Li Keqiang proposed the “Internet +” action plan.Since then the “Internet +” model quickly spread across all walks of life and became the new darling of today's society.New forms of teaching are emerging from “Internet + education”,such as micro-curriculum,motto and flipping classes,etc.Chemistry is a natural science based on experiments.In chemistry teaching,experimental teaching has an irreplaceable position.With the rapid development of information technology,experimental teaching has changed from physical experimental teaching to virtual simulated experimental teaching,which reduces the risk of experimental operations.In addition,it can “visualize” experiments that have been difficult to operate,and attract students to learn and help teachers improve their teaching abilities.As the application is expanding in subject teaching,it is necessary to deeply introduce virtual simulation experiment to the study and increase the learning interest of students.This paper starts with the innovative “Internet+ education” mode,and proposes a new homework mode—simulation experiment homework based on the theory and factual status of virtual simulation experiments at home and abroad.Through experiments,teachers show learners key and difficult points in the learning process.Learners are no longer limited to theoretical knowledge and mechanical reception of textbook,but can conduct autonomous exploration through chemical experiments.The highlight of chemical experiment teaching lies in experiment.It is no longer the traditional “cramming” education model.Instead,it leads students to the leader in the classroom.Using virtual laboratory simulation software,students can not only complete simulation experiments on homework,but also can conceive experimental contents by themselves to complete exploratory operations.Students can conduct hands-on experiments,enjoy the success of experiment,and develop their hands-on experience.In this paper,the Chemist mobile software developed by THIX company was designed for the complete design of the experimental content of Chapter 3 Metal and Compound in high school chemistry.The workable experiment was arranged into homework.In two experimental class,93 students finished a questionnaire survey before the experiment.Totally 8 questions were asked,including "Is there a mobile phone in your home?" "How long are you playing a cell phone a day?" "Do you want to start your own chemistry experiment in chemistry class?" "Do you think chemistry experiments important in chemistry teaching?" After the experiment,7 questions were asked to 45 students in the experimental class,involving the satisfaction with the current teaching mode,the teaching resources and cases.To carry out data analysis and statistics,the mid-tern test results and unit test results were collected and compared before and after the experiment.The final conclusion is that simulation experiment homework is a new type of homework.Its outstanding feature is that it is the students who carry out simulation experiment.This new mode changes students' learning attitude and interest,and improves students' practical abilities and scientific spirits.However,there are some weak points in simulation experiment homework.For example,the function of the simulation experiment software needs to be further improved.This paper makes an attempt to incorporate simulation experiment into out-of-class learning.It is also an attempt to break through the model of teacher demonstration in virtual simulation laboratory.The new homework mode needs further experimental research.
