Research And Practice Of Blended Teaching Mode Of 3D Printing Course In Junior High School

With the continuous implementation of the new curriculum reform of national basic education,3D printing education in primary and secondary schools in Ch ina has been recognized by the society and grad ually implemented,but there are many difficulties in the process of 3D printing education promotion,such as weak teachers,single teaching mode,lack of relatively appropriate learning tools and platforms.A t the same time,with the rapid development of mobile Internet,the contradiction between traditional teaching and chan ging learning needs is becoming more and more prominent,and blended teaching has emerged.Therefore,the study takes the3 D printing course in Shunfeng Junior Middle School in Shunde Di strict of Foshan City as the practical object,takes the constructivism theory,the teaching interaction theory and the multi-intelligence theory as the theoretical guidance,and combines the online Moodle platform to construct the three modes of blended teaching based on 3D printing course,that is,the knowledge-mastered teaching mode,Skill improvement teaching mode and inquiry and expansion teaching mode,based on these three models developed a set of blended curriculum resources for junior high school teaching,and carried out three rounds of action research,summarized and analyzed the teaching effect of blended curriculum.The paper is divided into six main parts:The first part is an introduction,which summarizes the research background and problems of the thesis,the current situation of research at home and abroad,the purpose and significance of the research,the content and methods of the research.The second part is the definition of concept and t heoretical basis,the paper involves the hybrid teaching model,3D printing courses and other related concepts and theoretical basis to define.The third part is to construct a hybrid teaching model based on 3D printing course,analyze the elements of teaching,and design three hybrid teaching modes of3 D printing courses based on the basic teaching mode and the nature of 3D print ing courses: knowledge mastery,skill enhancement and expansion inquiry.The fourth part is the development of a blended teaching curriculum based on3 D printing courses,according to the three models of blended teaching,combined with the online Moodle platform,the development of 3 knowledge masterclasses and2 skill enhancement,and 2 expanded inquiry-based curriculum resources,and used for teaching.The fifth part is the application of the blended teaching curriculum of junior high school 3D printing course,and the developed blended curriculum resources are carried out in Shunfeng Junior High School for a period of 12 weeks of three-round action research and corresponding teaching effe ct analysis.Experiments show that the blended teaching model and curriculum resources are beneficial to the learning interest of cultivating students’ 3D modeling,and the students’ evaluation satisfaction is high.The sixth part summarizes the results of this study,puts forward the existence of problems and the prospect of follow-up research.
