Teaching Design And Practice Of Primary School 3D Printing Course Oriented To Scene-based Learning Products

With the gradual reform of the education system and the continuous improvement of the curriculum content,information technology plays an increasingly important role in the entire education industry,and emerging information technologies such as artificial intelligence and 3D printing have attracted wide attention.Among them,3D printing course,as an important form of maker education,is gradually emerging,and teachers and students attach great importance to its cultivation of spatial concept and creativity.At the same time,the development of 3D printing course is still in the initial stage,and there are many problems in the teaching process,mainly manifested in the value deviation of 3D printing technology.Based on this,the purpose of this study is to optimize the teaching through scenario-based product design,and finally form the value realization of 3D printing from creativity to reality through specific teaching practice.This research will study scenario-based product as a guide the new idea of instructional design for 3D printing,on the basis of situational learning theory,the "backward thinking" interpretation and analysis of the learning process model and the design thinking,build into the scenario elements of the framework of instructional design for 3D printing,has carried on the back to teachers and students activities of deconstruction,based on the research of design method is used to carry out the three rounds of iterative experiments,finally the framework be revised and perfected.This research selected students in grade four from Nanjing Y primary school as object of teaching experiment,with 3D printing theory knowledge and the sketchup the use of 3D modeling software for the teaching content,select “room” scenario design,“classroom” scenario design,creative scenario design as the theme of the three rounds of teaching experiment,on the basis of previous design framework generates the three rounds of teaching experiment teaching plan.In three rounds of teaching experiments,the author tested the learning effect of students through classroom observation,after-class interview and work analysis.The first round of teaching experiments mainly investigated the basic operation of students’ modeling software and the formation of spatial concepts.The second round of teaching experiment mainly strengthens the advanced operation of students’ modeling software,cultivates the students’ ability to find and solve problems,and emphasizes the sense of teamwork.The third round of teaching experiment mainly focuses on the cultivation of students’ creativity and imagination and the ability to express their own ideas through 3D printing technology.Through a complete teaching experiment,students can enrich their knowledge system of 3D printing.
