Application And Study Of Microlecture In The Preparatory Course Of Mathematics In Junior Middle School

The 21st century is an era of the Internet,the Internet of Things,artificial intelligence,big data,and cloud computing.It is also an era in which modern education technology and curriculum integration have flourished.Many educational models and methods with distinctive characteristics of the times have emerged one after another.Among them,microcourses with "micro" as a prominent feature are one of the representatives.Microcourses make mathematics learning more vivid and interesting,make the presentation of mathematical knowledge more lively,and can effectively allow students to explore the mystery of mathematical knowledge.Help students to develop good mathematical thinking and application ability in practical problems.Based on the theory of constructivism and refinement,this paper studies the origin,characteristics and advantages of the application of microcourses in junior high school mathematics preparatory study,investigates the current situation of the application of microcourses in junior high school mathematics,and compares the application of microcourses pre-study with the traditional pre-study.Microlesson preparation is better than traditional study preparation,but there are also many problems,and put forward their own suggestions and strategies for the problems in this link.This paper adopts the methods of questionnaire survey,interview,case analysis,and documentation,and conducts a multi-angle survey of 10 teachers and 300 students in Jiahe No.3 Middle School,and analyzes the corresponding data.The main problems of getting the current pre-study status of microclass before junior high school mathematics class are:(1)The serious lack of microclass teaching facilities;(2)The relevant education administration departments,students and parents have deep prejudice against microclasses;(3)Teachers ' ability to master microcourses is limited and their skills are scarce;(4)The implementation of microcourses may lead to a widening of the learning gap between students.Based on the analysis of these problems,some suggestions are put forward:increasing the investment in teaching media equipment;(a)Take measures to update the perception of microcourses among the relevant educational authorities,schools and parents of students;Strengthen the teacher' s microlesson training,so that teachers continuously improve their ability to design and produce microlesson.On the basis of this,the author designs the design cases of "real number"before class and "multiplication" before class,which can provide some theoretical reference for other researchers,and further understand the practical value and practical significance of this study.
