Research On Optimizing The Teaching Of Chemical Knowledge In Middle Schools Based On Virtual Simulation Technology

The chemical knowledge in middle school is an important material for the theory and practice,which is of great value to the development of the core quality of students.Although the significance of chemical knowledge in the middle school chemistry teaching,but the actual teaching of chemical knowledge,easy to be ignored,there has long been the phenomenon of ineffective teaching,the gap between chemistry teaching and lead to actual production,is not conducive to the development of students' core literacy.Virtual simulation technology is a kind of technical means to simulate the actual system instead of the actual system.Design and Simulation of the visual image of the complete chemical production process by using the virtual simulation technology,the auxiliary in the middle school chemistry knowledge teaching,can solve the problems existing in the current middle school chemical knowledge teaching,help students understand the knowledge in chemical process technology,it is suitable for the teaching of chemical knowledge.In view of this,in order to help the smooth development of middle school chemical teachers knowledge teaching,optimizing middle school chemical knowledge teaching,to relieve students fear of chemical knowledge,promote the students' core competence development,this paper mainly do the following work:For a long time,the teaching effect of chemical knowledge middle school poor phenomenon,analyzes the core from the perspective of chemical knowledge literacy education function,the causes of the poor teaching effect of chemical knowledge,the development of the visual image based on virtual simulation technology based on CorelDRAW,Photoshop,Lab VIEW and other software based with industrial sulfuric acid production process consistent the user interface and show the contact process simulation teaching software for the motion of micro particles and transformation process in the production process.In constructivism,humanistic learning theory and deep integration of information technology with curriculum theory,the simulation of chemical teaching software and the specific teaching content with teaching design,finally selected two parallel classes,using the method of chemical control experiment,simulation teaching software practical teaching effect has been tested.The study found that the chemical knowledge as the carrier of development subject core qualities focused to cultivate students' innovation consciousness,cultivate students'scientific spirit,students' sense of social responsibility;knowledge teaching effect is the social phenomenon of poor high school chemical curriculum,teachers,students,teaching method,factors.Chemical simulation teaching software compared with the ordinary teaching model,to achieve better teaching effect,the students in the reading and analysis of knowledge and technology,grasp the industrial flow chart are improved,the core quality further,to optimize chemical knowledge teaching in middle school.
