Application Of Multimedia Technology

With the development of the times,multimedia technology has been widely used in all levels of society.In the era of information network,countless educators have been exploring how to use multimedia information technology means to achieve modern education.With the continuous efforts of the countless educators,the methods and ideas of chemistry teaching are developing,and the multimedia educational products are becoming more and more abundant.All kinds of new teaching methods,such as overturn class and micro-class,are widely spread and applied in our country and foreign teachers.With the rapid development of multimedia technology,great changes have taken place in teaching and learning of contemporary education.The application of multimedia technology in chemistry teaching conforms to the development law of the present age.This paper aims to study the application of multimedia technology,and mainly introduces the teaching and learning of junior high school chemistry based on the network platform--Xueleyun platform.By introducing the status quo of multimedia technology at home and abroad and studying the application of multimedia technology Xueyun teaching in middle school chemistry teaching and learning to publicize the advantages of multimedia technology in teaching and learning;For teachers who are not skilled in using multimedia technology,we will help them with knowledge methods to improve their teaching level and teaching ability.In addition,through the introduction of popular science,more students learn to learn independently through multimedia technology.The author selected two classes with similar basic results in Grade 3 of A nine-year system in Banan District of Chongqing to carry out two comparative teaching experiments: First,Class A used traditional teaching methods to teach Unit 3 "Mystery of Substance Composition" in Grade 9 Chemistry Volume 1 of junior high school and used Xueleyun platform to teach Unit 4 "Water in Nature" in Grade 9 Chemistry Volume 1 of junior high school The comparative experiment of learning;The second is to use the traditional teaching method of class B to teach the content of Unit 4 to form A contrast experiment with class A.For the teaching of Unit 4,"Water in Nature",class A and Class B have the same class content except for different teaching forms and homework methods.After finishing the teaching experiment,the author completed two things: one is to do the same regular homework for class A and Class B on the content of Unit 4,and make a simple analysis of the results;The second is to conduct A simple questionnaire survey and interview on the use of Xueyueyun among students in Class A.By analyzing the average score,excellent rate,pass rate,difference rate and questionnaire survey of students.This finding: by contrast,in the test of "Water in Nature",the average score,excellence rate and passing rate of class A were higher than that of class B,while the difference rate was lower than that of class B;Through the teaching and learning of Xueleyun platform,students are more impressed with what they have learned and have a higher mastery rate.Some students with relatively poor foundation also like this teaching method based on Xueleyun.To sum up,the teaching and learning effect of junior high school chemistry based on multimedia technology is better!The deficiencies of the research are as follows: first,the content of the experiment is too simple,only two sections are selected for teaching experiment comparison;Second,the number of teachers and students participating in the experiment is small.Only one teacher and two classes of students from a nine-year school in Banan District of Chongqing participated in the experiment,which is not universal.For the multi-dimensional interaction between school,teachers and students and parents,the multi-dimensional interaction between multimedia technology--Xueleyun platform can make the atmosphere more positive,so that parents can see hope,so that students have more confidence,under such conditions,so that students can improve their knowledge,skills,emotional attitude and other aspects.Show the use of Xueleyun platform can make more teachers and students understand learning,so that teachers teach more easily,students learn more interesting!...
