The Design And Application Of Microlecture In The Mathematics Review Lesson Of The Grade 7

With the rapid development of information technology,a new model named ’Internet plus education’ also started to penetrate into the field of education.As one of the main subjects of basic disciplines,mathematics is of utmost importance.At present,mathematics review lessons are necessary to improve teaching efficiency,because there are some problems such as too much teachers’ explanation and neglecting students’ thinking in the mathematics review class of middle school.As a new informationized education resource,microlecture is tiny and diversed.Therefore,the microlecture has infinite application space and operability in the field of education and teaching.The author starts the paper with summarizing the microlecture design patterns;designing and producing microlectures to be applied to teaching of mathematics review lessons;inquiring whether be used to improve students’ interest and scores in learning when microlectures are applied on teaching of mathematics review lessons;whether to make the presentation of mathematics more easily to understand and so on.The author summarizes the microlecture design patterns through analyzes many literaturethes about microlecture and research classic microlecture application cases.Then,two microlectures named ’3D graphics’ and ’Coangle and supplementary angle’in the chapter of ’Preliminary Geometry’ are design and experiment on the reality teaching of mathematics review lesson of Grade 7.The author completed the experiment in two parallel classes of Grade 7 by various methods,including independent-sample t test and paired-samples t test,questionnaire survey and teacher interviews.The author does a research on the feasibility of applying mathematics review microlecture to mathematics review lessons,with the purpose of providing references for microlecture design and application based on the mathematics review classroom of Grade 7.Through the above research,it was found that microlectures can be well applied to classroom teaching in mathematics review lessons of Grade 7,and can also guide students to conduct self-study after class because of microlecture design patterns are streamlined,diverse,convenient and practical.And the students’ interest in learning was greatly enhanced and the scores were significantly increased through teaching in mathematics review microlecture.In addition,the presentation of mathematics is more easily to understand.Students have better mastery of mathematics knowledge.However,microlecture still have problems such as poor control of classroom teaching.Microleture also cannot completely replace the traditional classroom.We must design microlectures in conjunction with actual teaching situations.
