Based On The WeChat Public Platform,the Application Research Of Junior High School Students' Independent Learning Of Mathematics After Class

In this era of information technology explosion,education informationization has become an inevitable trend.With the advent of the era of new media,more and more applications arise at the historic moment.As one of the mainstream social softwares,Wechat gets the favour of the masse.The emergence of WeChat public platform provides a good opportunity for people to receive resources and increase interactions.It can also create a kind of mobile learning approach for people under the network environment.It will be a new experience to introduce the platform to junior high school students in extracurricular autonomous learning.Therefore,this study is based on the WeChat public platform for junior high school students to learn mathematics independently after class.This research adopts literature research and survey method of questionnaire,observation method and interview method.It is finished with the support of the constructivism theory,the humanism theory,the ubiquitous learning theory and the cognitive load theory.It is combined with the principles of designing micro study,mobile learning and general teaching that relevant scholars put forward as well as the study subjects' learning needs.Then the designing principles of the WeChat public platform for"the small class of happy mathematic" are proposed.And according to the designing principles for the plat,we develope and applicate the platform."The small class of happy mathematic" WeChat public platform includes three modules:the automatic reply,the custom menu and the daily push to share junior high school mathematics knowledge with junior high school students.The automatic reply mainly shares junior high school mathematics electronic textbooks.The custom menu is divided into three parts:knowledge sorting,method guidance and interest cultivation.The menu of each part is divided into several sub-menus to share corresponding mathematical knowledge to junior high school students.In the daily push,the content of "the star of today","reviewing the past and learning new things","one question per day" and "tips about senior high school entrance examination" will be pushed to junior high school students at a specific time every day to help them develop the habit of independent learning after class.After the application of the platform in the experimental class,through the questionnaire and teacher interview,this study found that junior high school students and the teacher held a positive attitude to the public platform for extracurricular autonomous learning and are satisfied with the design and study content of this platform.Most of them are optimistic about the use of the platform.In addition,through analyzing the platform usage,class performance and the test results,we can find that "The small class of happy mathematic " WeChat public platform for junior high school students has a certain role in promoting extracurricular autonomous learning mathematics,improving the junior high school students' autonomous learning ability.It has attracted the interest of junior high school students' mathematics learning and improved the junior high school students' math grades.
