Design And Practice Of Visual Chemistry Teaching In Ninth Grade Under Information Environment

Since the 21st century,the world has entered the information age.The modern educational idea and educational information technology have achieved considerable development,which has brought great impact on the traditional education and effectively promoted various changes in the field of education.Nowadays,human beings are living in a visual era.People’s way of obtaining information tends to be more pictorial,film and television and image symbolization.The implementation of visual teaching just conforms to the needs of students to change the way of knowledge disseminati.Based on the basic education stage,this research focuses on the hot issue of "visualization teaching of chemistry in grade 9 under the information environment".Based on the previous research,the main work of this paper is as follows:First,through reviewing the relevant literature,this paper summarizes the research on visual teaching at home and abroad,defines the concept of visual and visual teaching,a survey was conducted on hardware facilities,teachers’ ideas and students’ attitudes in the region.And the visualization techniques and tools involved in the teaching of ninth grade chemistry were sorted out,including Power point courseware,interactive electronic whiteboard courseware,thought map,concept map,flow chart,micro video,micro animation,basic experiment,innovation practice Experiment,simulation experiment,digital experiment,recording and broadcasting classroom system,intelligent classroom system,examination diagnosis and analysis platform,mobile tablet app,3D printing,AR/VR technology,etc.Secondly,combined with the author’s own actual teaching work,we have analyzed the strategies of chemical visualization teaching in Grade 9 under the information environment,which includes teaching analysis stage,teaching design stage,classroom teaching stage,after class feedback stage,teaching evaluation stage,etc.At the same time,the paper provides methods in grade nine chemical visual teaching with informatization,from two aspects,which are the teaching process and teaching content of visualization.The application of visualization techniques and tools in scientific inquiry,chemical substances around us,the mystery of material composition,chemical changes of substances,chemistry and social development are mainly discussed.Thirdly,the design and practice of visual chemistry teaching in grade 9 under the information environment are carried out,visual teaching is applied to special classes and traditional teaching is applied to ordinary classes.Typical new lectures,review lesson and lesson of comments on examination paper are listed in this paper.It took eight months to evaluate students in two classes,the special class and the regular class.The knowledge test paper was designed to test the students of the two classes before and after the experiment,and then the test results of each class before and after the experiment were compared and analyzed.Some students in special classes and chemical teachers were interviewed and analyzed.At last,the new direction of visualization teaching in Grade 9 under the information environment is prospected and predicted.It is found that the implementation of visual chemistry teaching in Grade 9 has a positive impact on students’attitude towards chemistry learning,understanding and construction of chemical knowledge,chemical thinking ability and chemical learning achievements.The whole research ensures the objectivity,authenticity and reliability to the maximum extent,it is hoped that this study can provide a positive reference for the ninth grade chemistry teaching reform,contribute to improvement of the ninth grade chemistry teaching quality.
