Research On The Teaching Practice Of Elementary School Geometry Unit Based On Micro Video

In the era of big data,the teaching mode of mathematics in primary schools and the way students learn are changing.The knowledge content of the "graphics and geometry" section of primary school is very abstract to middle and lower grade students,and through teacher-professor,it is difficult for students to imagine geometric models and learn understood.The new curriculum clearly states: "Hands-on practice,independent exploration and cooperative communication are important ways for students to learn mathematics."Can we use micro-video to improve the classroom teaching effect of the mathematics "graphics and geometry" unit in the lower grades of primary school? Based on this research problem,and referring to the various practical studies of the teachers of the previous generations,this paper is intended to be based on micro-video for the teaching design and teaching practice of the middle and lower grade "graphics and geometry" unit,hoping to explore and promote the effective learning of middle and lower grade students in the graphics and geometry unit.The full text is divided into eight parts:Part One: Introduction.The topic is changed from a new course to a background,with the aim of proposing effective teaching strategies,and the method of combining literature research,investigation and practice research.Part ?: A review of literature.Effective teaching is based on the theory of learning center and constructivism learning theory,respecting the main position of students,giving the initiative of the classroom back to the students,so that the students can learn well and the students develop the teaching well."Teaching by learning" is the basic starting point for effective teaching evaluation.The third part: the primary mathematics "graphics and geometry" unit based on micro-video teaching of the current situation of investigation and analysis.Design the questionnaire of primary school mathematics "graphics and geometry" teaching,divided into teacher questionnaire and student questionnaire.Through the teacher questionnaire to understand the current teaching in the field of mathematics "graphics and geometry" in primary schools,to find out the common problems.Through the student questionnaire,you can understand students' interest in graphics and geometric content,as well as the teacher behavior in the student's perspective.The fourth part: the feasibility analysis of "graphics and geometry" unit based on micro-video.According to the characteristics of the teaching content of the "Graphics and Geometry" module and the different stages of students,the teaching content based on micro-video is selected and classified.Part ?: The classroom teaching design of "graphics and geometry" in primary school mathematics based on micro-video.Part 6: The classroom teaching practice of "graphics and geometry" in primary school mathematics based on micro-video.The author based on the classroom,the use of micro-video on the second and third four grade of primary school related geometric content teaching practice.Part 7: Evaluation of the classroom teaching effect of "graphics and geometry" in primary school mathematics based on micro-video.Part ?: Summary and Outlook.
