Investigation On The Application Of Mathematics Micro Lecture In Primary School

With the rapid development of information technology,micro-lecture,as a new type of educational learning resources,have been widely used in teaching activities,especially in primary and secondary schools.The application of micro-lessons in primary school teaching has its unique advantages: it takes a few minutes of short video as the carrier,the theme is prominent,the sound and light can be integrated into one,can better attract students' attention,mobilize students' interest in learning;It can be used repeatedly,which is beneficial to students' self-study and reason after class,and it can be used in flipping class,improving learning efficiency and supporting individualized teaching.Micro-lecture not only stimulate the enthusiasm of students to learn,but also enrich the teaching form of teachers,and orderly.The perfect micro-lecture video resource bank also enriches the teacher's lesson preparation resource,and helps the teacher's professional development.Through literature analysis,questionnaire survey,interview and classroom observation,13 mathematics teachers and 243 students in Qilihe X Primary School in Lanzhou City were investigated with the help of teacher questionnaire and student questionnaire.This paper analyzes the present situation of the application of micro-lecture in primary school mathematics,and draws the following conclusions:(1)most teachers accept micro-lecture for more than 2 years,some teachers often take part in micro-lecture training activities,and the frequency of micro-lecture application in class is not high.Mainly to enrich the form of classroom teaching;Students like the teaching resources of animation video,like teachers to use micro-lecture to assist teaching in the classroom,and are very willing to use micro-lecture after class.Learning.(2)the main way for teachers to obtain micro-lecture is recommended by their colleagues(friends).The frequency of teachers making micro-lecture themselves is not high.Teachers often use PPT video screen to make micro-lecture.(3)Teachers tend to apply micro-lecture to after-class guidance,and students prefer teachers to apply them to micro-lecture at the beginning of each class.Teachers are the mostcommonly used in the teaching of graphics and geometry,and only a small number of students often use micro-lecture to learn after classes.(4)Teachers generally think that the application of micro-lecture is helpful to the improvement of teaching quality.And the attitude towards the application of micro-lecture to primary school mathematics is positive,and the micro-lecture is positive to stimulate students' mathematics.Interest in learning plays an obvious role in improving students' classroom participation.Combined with the results of questionnaire survey,classroom observation and teacher interview,this paper analyzes the factors influencing the application of micro-lecture in mathematics in primary schools,which are mainly attributed to four factors: resource bank factor,school factor,teacher factor and student family factor.At the school level:(1)perfect the micro-lecture resource base(2)strengthen the team building of micro-lecture;(3)strengthen the propaganda of micro-lecture;At the teacher level:(1)correct the concept of micro-lecture application;(2)actively participate in micro-lecture observation learning;(3)improve the production and application level of micro-lecture.
