Design And Application Of 3D Printing E&T-CDIO Teaching Model In High School

As China attaches importance to the development of advanced manufacturing,3D printing is gradually well-known,and it also promotes the development of 3D printing technology in the basic education stage.Many middle schools and primary schools have gradually set up some 3D printing courses.Despite this,the development of 3D printing courses in high school information technology is still at an early stage.There are many problems,such as confusion of teaching content,random teaching process,and no unified teaching mode for first-line teachers.Therefore,it is of great significance to explore a new high school 3D printing course teaching model.The purpose of this study is to use first grade students as research objects,and to construct a teaching model suitable for high school 3D printing course teaching.The purpose is to develop relevant theories such as constructivism theory,multiple intelligence theory,CDIO teaching model,and the development of 3D printing courses.Based on the collection of literature,combined with the characteristics of the high school 3D printing course and the requirements for the 3D printing course in the "General Information Curriculum Standards for Senior High School(2017 Edition)",the E&T-CDIO teaching model for high school 3D printing courses was constructed.Based on this model,the specific teaching design will be applied to practical classroom teaching.Finally,through the analysis and summarization,the purpose of providing models for the implementation of the curriculum is to learn from and enrich the CDIO teaching model.The author investigates the effects of the model’s application of the model through questionnaire surveys and interviews.It is found that this model can improve students’enthusiasm for learning,foster students’ awareness of cooperative learning and self-learning,and finally obtain high school 3D printing courses E&T-CDIO teaching model is suitable for use in the teaching of high school 3D printing courses,demonstrating the feasibility of this teaching model.The innovative point of this study is to find a match between the characteristics of high school 3D printing courses and the CDIO mode of engineering education,boldly adopt the localization of the CDIO teaching mode that is commonly used in Colleges and universities,and build E&T-CDIO teaching mode for high school 3D printing courses.
