Design And Development Of Primary School's 3D Printing Stereoscopic Teaching Material For Maker Education

Under the background of the global informatization,Maker Education is coming into the school.Maker Education integrates into science,mathematics,physics,chemistry,art and other disciplines to cultivate students' imagination,creativity,problem-solving ability.The "Maker" educational model brought a combination of innovative education,experiential education,project learning and so on.Students no longer passively receive the knowledge and can have multiple roles,such as mathematicians,scientists,Inventors,and so on.Therefore,they have the choice to use mathematic,physic,chemistry,art and other disciplines.While the wave of 3D printing technology swept the world,China's primary and secondary schools also began to bring 3D printing technology into classroom.However,there are still some problems in the development of 3D printing courses in primary schools,such as the lack of 3D teaching materials for primary school education,the demand for teachers to teach the courses,and the deficiency of 3D printing courses.Based on the cognitive characteristics of primary school students and from the perspective of students' design thinking,the study conforms to the requirements of 3D printing course in primary school stage and has the curriculum system to develop the creative thinking,and finally develops a complete set of 3D teaching materials which include the primary 3D printing textbooks,micro-video tutorials,case libraries,and 3D printing thematic sites.We use the project-based and modular way during the class.Meanwhile,the students are guided by the group to discuss the questions,do the brainstorming,and use some tools such as the mind map to design the creative works.Eventually,they are encouraged to output works by the group's showing and games.We combine online learning with offline learning approach to promote students hands-on ability,practical innovation,teamwork awareness,called online and offline integration.During more than one year of design and preparation,the 3D printing stereoscopic teaching material has also been initially completed called small designer-3D print creative practice tutorial which have the three chapters,twelve case modules and total 24540 words.This book is composed of the general micro-video tutorials and micro-video tutorials to expansive learning included all the case models in the textbook and the expansive resource files.Every model contains three file formats for students to modify or print directly,The 3D printing thematic website contains online classes,student works,forums and other functional modules.Based on that,the 3D printing stereoscopic teaching material is used in education in Haiwan Primary School of Nanshan District,Shenzhen.The practical application of this book shows that it can solve the needs of primary school 3D printing courses and meet the actual needs of teachers teaching and student learning for primary school.This is the new and creative way to carry out 3D printing courses and provide a system about the learning models.Project design,mind map,group cooperation and other designs effectively promote student team awareness,design thinking and help students improve the overall quality.However,we also found some problems in the investigation process,which is that the model of mixed grade student group to learn increases the difficulty of teaching.We need to think how to ensure the teaching orderly.There is still a lot of possibilities to enhance online and offline integration and the design of teaching module,which will be improved in the follow-up study.
