Research On The Design And Application Of 3D Printing Learning Activities In Primary Schools From The Perspective Of Generative Cognition

In the current process of actively implementing 3D printing course in schools,how to effectively design 3D printing learning activities to achieve learning goals,promote learners' ability development and thinking enhancement,has become the key to measuring the earning effect.The mainstream teaching methods adopted in 3D printing courses in schools are still the general mode of traditional design courses:teacher lectures-student exercises-task-driven to promote the design and learners' works;the mode is conducive to learners to become familiar with and master 3D modeling about use of software and 3D printers,but the lack of context in learning content,the bias of learning process towards technical operating,and the focus on knowledge skills in learning results,it's no value to learners' further in-depth knowledge learning and ability training,and it's also difficult about the cultivation and promotion of learners' thinking.Enactive cognition is an explanation and illustration of learner's cognitive formation mechanism,which emphasizes that cognition is formed in the process of embodied action,the final result is the formation of learner's higher-order thinking.Based on the characteristics of situationality,embodiment,subjectivity,action,and higher-order thinking,it can effectively encourage learners to engage in embodied processes such as placing themselves in context,perceiving experience,and subject interaction in learning activities,and learning as a body and mind experience forms cognition and promotes the development of thinking.Therefore,this research takes the improvement of the current status of 3D printing teaching as the starting point,extracting the characteristics of the enactive cognition and proposing the practice path,and integrates them into 3D printing learning activities,then constructs the 3D printing learning activity framework in perspective of enactive cognition,to encourage learners to complete 3D products in the process of embodied action: In the theme establishing learning activities of physical and mental immersion,learners though physical embodiment to experience perception,which is expressed as problem discovery and establish the production theme;In the production and learning activities of embodied interactive works,learners actively interact through actions embodied,which is manifested in the process of project conception and dynamic creation;In the evaluation and reflection learning activities of thinking development,evaluate learners' by multiple ways according to the corresponding evaluation criteria,prompt learners to modify and improve the 3D products,and promote the formation and development of thinking through the process of migration and reflection.At the same time,implement specific learning activity design based on this framework,evaluate students' learning effects and the effectiveness of the learning activity framework through case implementation,and finally summarize experience and improve the framework.After implementation of the case,it was found that the development of3 D printing learning activities from the perspective of enactive cognition can takes the improvement of the current status of 3D printing teaching;effectively improve the process quality of learners' 3D products;can improve the teaching effect of 3D printing courses;can promote the development of learners' thinking and form higher-order thinking.The paper is divided into six chapters: Chapter 1 is the research introduction,which mainly introduces the definition of concepts,reasons for the topic,research goals and content,research methods and routes,etc.;Chapter 2 is research summary,which mainly summarizes the related theoretical research of enactive cognition and educational practice,the teaching development of 3D printing courses and the use of effectiveness tools;Chapter 3 is the feature extraction and practice path of enactive cognition,clarifying the characteristics of situationality,embodiment,subjectivity,action,and higher-order thinking,then express the practical path of physical embodiment,action embodiment and imagined embodiment;Chapter 4 is the framework construction,starting from the characteristics and practical path of enactive cognition,it constructs the theme establishment,conception production,and evaluation rethinking of the 3D printing learning activity framework,then design the corresponding learning activities under the framework;Chapter 5 is the framework application,according to the framework design to implement the teaching practice of three themes,and iteratively modify and improve the framework through design-based research;Chapter 6 is summarizes and prospects,summarizes experience and shortcomings based on research results,and an outlook for future research.
