Research Of Microlecture Design And Application In Mathematics Teaching At Elementary School

With the continuous development of information technology,micro class,as a new teaching method,has attracted more and more educators’ attention and research.Micro lesson is intuitive,short and repeatable.It can stimulate students’ interest in learning and improve teaching effect by reasonably applying micro lesson to subject teaching.It has an important role in promoting students’ better learning,understanding,mastering and applying knowledge.However,in the actual teaching,teachers and students have many obstacles to the design and application of the micro lesson,which restricts the exertion of the teaching effect of the micro lesson,and is not conducive to the innovation and development of the teaching mode.This article is divided into five chapters.The first chapter is the introduction part,aiming at the research background,purpose and significance of this article,and make a literature review,analyze the research status of the predecessors at home and abroad,and put forward the research train of thought and researc h method in this paper.The second chapter is a conceptual part of the definition and characteristics of the micro class.The design of micro class and the theoretical basis of micro class are summarized.And put forward the feasibility and necessity of micro class in primary school mathematics teaching.The third chapter is the investigation of the present situation.Take A primary school as the research object.From the design and application of the micro class,this paper investigates the application of A primary school in the view of the application of micro class,the design of micro class and the application of the micro class.The fourth chapter is the problem and analysis.Through the investigation,there are five main micro aspects of the course design: the micro class design does not truly reflect the "micro";the micro course design lacks a certain attraction;the development of micro resources education serious enough;the micro class video recording is relatively rough;micro class the design process is lack of effective reflection and summary;secondly,micro class application also exists in five aspects:the problem of teachers’ concept;the use of micro class teachers to form a single,content of curing;teachers relatively backward production skills;the micro class comparison concentrated applied before or after class,use less in class;the lack of effective micro class learning feedback mechanism.The reasons for these problems exist in three aspects: the teacher level,the student level and the social level.The fifth chapter is the countermeasure analysis,aiming at the problems existing in the design and application of the A primary school in the micro course,the concrete solutions are put forward.The author believes that the design and application of micro lesson in primary school must do the following eight aspects: one is to adhere to the three principles of micro class design;the two is to choose according to the needs of teaching and practical design content is three supporting resources to prepare rich;the four is to the scientific record micro video;five is to summarize and reflect on micro class good design;the six is to change the idea,improve the understanding of the micro class;seven is to micro class form and content innovation,improve micro class production skills;eight is to be introduced into the micro class classroom teaching and the establishment of micro class autonomous learning feedback mechanism.
