Research On Classroom Teaching Strategy Design Of 3D Printing In Middle School

In middle school,3D printing classroom teaching can better stimulate students’ innovation consciousness and improve students’ creative ability.At present,the 3D printing course in middle school has not formed a unified curriculum standard and teaching plan,which leads to a lack of instructive opinions for reference.This study aims to explore teaching strategies to support middle school 3D printing classroom activities and provide reference for the effective development of 3D printing course teaching activities.Based on a systematic review of the literature related to maker education and 3D printing,this study deeply interprets the advantages of maker teaching mode.Based on the theories of constructivism,zone of near development and teaching design,and based on the design principles of student subject principle,situational principle,heuristic principle and synergistic principle,this study analyzes the advantages of maker teaching mode.The teaching strategies of middle school 3D printing at five levels of creativity,design,production,sharing and evaluation are preliminarily constructed.Then,on the basis of this teaching strategy,the 3D printing classroom teaching strategy is strictly implemented according to the five processes of creativity,design,production,sharing and evaluation,with the students of Grade One of X Middle School in Yantai City,Shandong Province as the research object and the action research method as the research method.By the teachers review,field observation,student performance,student work and other ways that 3 d printing classroom teaching strategy on the problems existing in the concrete implementation process,pointed out the direction of improvement for the next round of action research,and at the end of each round of action research,understand the student interest in 3 d printing course degrees satisfaction,for 3 d printing classroom teaching strategy,Finally,the effectiveness of the strategy was verified by analyzing the interview records of students,and the 3D printing classroom teaching strategy was continuously improved to make it more suitable for 3D printing classroom teaching.Through three rounds of action research,the following conclusions are drawn: First,the 3D printing classroom teaching strategy designed based on maker teaching mode is constructed and tested to be feasible,which can support the development of 3D printing classroom teaching;Second,in terms of students’ interest in 3D printing courses,the average score of action research in each round was higher than that in the previous round,which maintained an upward trend on the whole.In terms of students’ satisfaction with teaching strategies,the score of the satisfaction was higher than the passing score in each round,especially the score of the third round was significantly higher than the previous two rounds,and both students’ interest and satisfaction were improved.Therefore,the 3D printing classroom teaching strategies designed in this study are helpful to guide the orderly development of 3D printing classroom teaching activities and improve students’ innovation consciousness and practical ability.
