The Practice And Research On How To Improve The Efficiency Of Chemistry Revision In Senior3with Multi-media Technology

With the rapid development of the computer multi-media technology, Multi-media Aid Teaching has an impact on traditional teaching mode and becomes the most attractive teaching means. Multi-media can present a large number of teaching contents, in the form of computer pictures, characters and sounds, to realize the diversity of teaching and learning and improve teaching efficiency The application of multi-media technology in chemistry teaching of senior3is the effective way to improve the revision efficiency of senior3.The research is based on the basic theory of modern education,is guided by the new curriculum and absorbs the previous experience. According to the characteristics of the revision of senior3and the cognitive laws of high school students, the research combines multi-media with teaching depth of senior3and is confirmed in chemistry teaching of senior3.The research mainly uses experiment method, questionnaire method, and case analysis, selecting two classes of senior3from the first middle school of Lutai for comparison, with stratified sampling, each class is chosen40students as the samples, selecting the experimental class and the compared class randomly. The compared class adopts the traditional teaching method to teach chemistry of senior3The experimental class adopts the multi-media teaching method Pay attention to reliability and validity, measure the teaching effect of chemistry, input the measure data into the computer and deal with Excel software.The teaching effect of chemistry is checked with Z.The result of the research illustrates:in chemistry teaching of senior3, multi-media has a positive effect on chemistry teaching and is advantageous for students to activate their learning and is beneficial to improving the efficiency of revision and does good to improving the academic performance of students in chemistry. The teaching method of multi-media can make the teaching process Three-dimentional,also make students take part in and experience the teaching process and promote active learning and research, which satisfies the concept of the new curriculum and the spirit of Quality Education.
