Design And Use Of Micro-course In The "Mathematics Activity" Section Of Su Ke’s Junior Middle School Mathematics Textbooks

With the deepening of curriculum reform,mathematics activities have become a hot topic in mathematics classroom.The change of this part of the teaching content is also reflected in the textbooks.The "Mathematical Activities" section is set up in the Suke version of junior high school mathematics textbooks.In the traditional mathematics activity class,due to the limited classroom time,insufficientawareness of students,insufficient materials and other reasons,there are some problems such as the lack of in-depth exploration of key activities.The purpose of this paper is to apply micro-course to the teaching of mathematical activities in the context of the information age and in accordance with the teaching requirements of mathematical activities.By discussing the micro-course of mathematics activity,we can improve the teaching of mathematics activity in junior middle school and meet the students’ individualized learning needs.This research mainly studies the design and application of "Mathematical Activities" in junior high school mathematics textbooks.Specifically include:(1)The current situation of mathematics activity teaching and the applicability analysis of micro-class,clear the problems of junior high school "mathematics activity" section teaching,and analyze the feasibility of micro-class applied to mathematics activity teaching.(2)Discuss the types of micro-class design of mathematical activities and put forward the principles and process of micro-class design.(3)Three examples of micro-course design of mathematical activities are given,namely,"Exploring Pythagorean Number","Puzzle Formula" and "Design of Packaging Carton".(4)Investigate the application effect of micro-course in mathematical activities,take "Exploring Pythagorean Number" as an example,and find that it is very helpful to stimulate enthusiasm of students for inquiry,break through difficulties and expand their knowledge.At the same time,it also alleviates the pressure on teachers’ teaching.Finally,the author summarizes and reflects this study.
