The Experimental Research On Improving The Efficiency Of "Pre-learning Guided Learning" Of Schoolchild Based On Mathematics Micro-lecture

With the rise of the concept of flipped classroom teaching and the rapid development of open online courses,micro-lectures have become another breakthrough for people to explore the reform of teaching models.The classroom teaching model of "pre-learning guided learning" is a new perspective to understand the relationship between teachers and students under the new curriculum reform and an effective attempt to create "efficient classroom".The purpose of this study is to analyze the application status of pre-learning-guided teaching,make micro-lecture as a supplementary means of pre-learning-guided teaching,make full use of different types of micro-lecture in different classroom teaching links,improve students' interest in independent learning,and improve the learning efficiency of mathematics classroom.Analyze the related literature of pre-learning guides,combines the teaching practice experience of pre-learning guides in the classroom,sorts out the current status of pre-learning guides,and understands the pre-learning guides' teaching practices in interviews with subject teachers Problems and cause analysis.The main characteristics of primary mathematics micro-lectures are sorted out through literature research.After analyzing the current micro-classification situation and classification basis,the classification of micro-lectures in this paper is set,which is beneficial to the combination of different teaching links to carry out micro-lecture teaching.Through theoretical research on the design and use of different types of micro-lectures and pre-learning guides,combined with the micro-learning design tables and pre-learning lists,the micro-learning in elementary school mathematics teaching has different teaching links such as pre-learning,guidance,and practice Application process.Then,in the third grade of the school,two classes were selected as experimental classes and control classes to demonstrate the teaching practice of different types of micro-lecture cases.Design corresponding questionnaires for learning detection and analysis,and then use questionnaires to analyze student learning related situations,and analyze and reflect on specific problems encountered in teaching practice.Through relevant practical research,learning analysis,and questionnaire surveys,the integration of micro-learning and pre-learning instructional teaching modes can improve students' academic performance and learning efficiency,stimulate learning interest,and motivate learning.In teaching practice,we found that micro-lectures can outline the key points of knowledge,or show some of them,but they cannot replace the entire teaching process.Integrating micro-lectures with ordinary classrooms and making full use of different types of micro-lectures in classroom teaching can enhance students' autonomous learning interest and improve mathematics classroom learning efficiency.At the same time,practice shows that when students choose to use micro-learning,they need to have clear goals and actively communicate feedback,and the effect will be more significant.It shows that although micro-learning is helpful to improve learning efficiency,it is necessary to find more solutions to organize students to effectively communicate feedback Method.In the era of micro-learning with the rapid development of the Internet,learning resources are more abundant and learning methods are constantly changing.At the same time,it promotes the reform of educational methods and the development of educational technology.Combining diverse educational methods with advanced teaching technologies is conducive to improving the effectiveness of teaching.Exploring the role of micro-learning in the pre-learning guidance teaching mode is a refinement of the pre-learning guidance teaching mode,a new fusion of the micro-learning teaching and the pre-learning guiding teaching mode,and a new technical support for the pre-learning guiding teaching mode.Through practical exploration of the design and use of different types of micro-lessons and tutorial cases,it can propose the application process of elementary mathematics micro-lectures in different teaching links such as pre-learning,tutorial,and practice.Teaching provides a certain amount of help and inspiration,and it is also a supplement to the research of developing elementary school mathematics micro-lessons.
