The Application And Practice Exploration Of 3D Modeling And Printing In The Teaching Of Solid Geometry In Junior High School

In today's primary and secondary school classrooms,with the in-depth advancement of educational informationization,teachers are trying to use various educational informationization equipment as a means of assisting teaching,hoping to improve teaching efficiency through the use of new technologies.In the traditional junior high school three-dimensional geometry classroom teaching,teachers often use stereoscopic geometry teaching in the form of pictures or physical objects.If 3D modeling and printing technology is used to carry out junior high school solid geometry teaching,students will be more interested,and the learning experience will be more real and learning.The effect will be better,and it will be more conducive to the development of students' spatial concepts.This research is to try to integrate 3D modeling and printing technology with the teaching content of junior high school solid geometry,and use 3D modeling and printing technology as an informational means to assist the teaching of junior high school solid geometry.In the teaching design of the teaching content of the fifth chapter of the third edition of the Su Ke version of the mathematics,the 3D modeling and printing technology is incorporated into the teaching design as a means to assist students in the study of solid geometry,and through the action research method.Apply instructional design to classroom teaching practice and test its effectiveness in classroom teaching practice.This paper completed the following four aspects of research:First,through the literature research method,combing the concept and principle of 3D modeling and printing technology,the domestic and foreign research status and theoretical basis applied in the field of education and mathematics teaching.Second,the research applied 3D modeling and printing technology to the teaching design of junior high school stereo geometry teaching.In this paper,the teaching content of the three-dimensional geometry part of the seventh grade of the seventh edition of the Su Ke version is used to integrate the 3D modeling and printing technology into the teaching design as a means to assist the students' three-dimensional geometry learning.Third,the teaching practice of applying 3D modeling and printing to the teaching of solid geometry in junior high school.Through action research,3D modeling and printing are applied to the teaching design of junior high school solid geometry teaching in classroom teaching practice.In classroom teaching practice,3D modeling and printing are tested through classroom observation,written tests and interviews.The practical teaching effect of solid geometry teaching in junior high school.Finally,the teaching practice process of applying 3D modeling and printing to solid geometry teaching in junior high school is summarized,and the prospect of applying 3D modeling and printing to solid geometry teaching in junior high school is proposed.
