| With the rapid development of social informatization and the vigorous promotion of education informatization in China.Online learning,mobile learning and other learning methods emerge as the times require and become more and more popular among learners.Based on this,With its advantages of "short,small,precise,tough" and simple use,flexible dissemination and easy expansion,the micro-lectures has rapidly become a hot application research.Primary school mathematics is an important subject in basic education.The syllabus requires students to acquire basic knowledge while enhancing their intelligence and thinking.Through the data and field investigation,we find that there are problems in primary school mathematics teaching,such as teachers neglect students' main bodies,students' knowledge in class is poor,and learning efficiency after class is low.It is necessary to deeply integrate information technology with education and teaching so as to promote the efficiency of after-school teaching.Information technology is applied more and more in the field of education.Education informationization has more and more influence on educational work and teaching activities.After its successful development in Khan Academy,TED and MOOC,micro-lectures entered China in 2011.Because of its advantages such as "short,small,precise" and easy to use,flexible and easy to expand,it has attracted everyone's attention and research.The state has also organized several micro lectures collection activities throughout the country to promote the construction and application of micro lectures throughout the country.But after years of leading events,the application of micro lectures in different regions shows a differential development.The application of micro lectures in Northwest remote mountainous county,represented by L County,is constrained by the unitary application mode and application atmosphere.It has failed to give full play to the role of micro lectures education resources in promoting education informatization and improving teaching integration.Therefore,the author applies the micro lectures application to the case of primary school mathematics after class,and selects the J Primary School of L county to carry out the application research of micro lectures,and explores the application mode and method of micro curriculum in classroom teaching,and promotes the practical application of micro lectures.In the literature review stage,the author uses the literature research method to review the relevant concepts and development process of the micro lectures,and to understand the knowledge base,characteristics and advantages,development means and application mode of the micro lectures,and the concept and connotation of the review.Learned constructivism theory,cognitive load theory,mastery learning theory and other educational theories,and drew lessons from existing application methods and successful experiences,which provided a theoretical basis for application practice.In the preparation stage,the author adopts the method of questionnaire to investigate the current situation of the review of mathematics class after grade five in primary school,and analyzes the difficulties and deficiencies in the review of primary school mathematics.Through field investigation,the feasibility of reviewing the micro lectures after class is analyzed from four aspects: students,teachers,schools and parents.Draw lessons from existing experience,make clear the design concept,design principles and design process,and design and develop a case of reviewing micro lectures after mathematics.With Case “Simple equation-Alphabetic representation” and case “Area of polygon-Trapezoid area“.In practical application stage,after a week's understanding,the author makes a scientific analysis of the students' mid-term examination results.It is determined that there is no obvious difference between the two classes in mathematics learning.Taking all factors into consideration,we selected two classes of grade five in J primary school in L county to conduct a controlled experiment.In the process,the author carries on the review effect monitoring to the experimental class and the control class.The test results were analyzed by SPSS software.Questionnaires and interviews were also conducted on student teachers.Comprehensive verification of the feasibility and effectiveness of micro course review after class.The feasibility of applying micro lectures to after-school review is verified through research.It is concluded that the application of micro lectures in reviewing after class can effectively enhance students' interest in learning and focus,enhance students' review efficiency and reduce the pressure of classroom teaching.In the end,The author puts forward strategies and suggestions for the application of micro courses in after-school assisted teaching. |
