优势与挑战:设计思维支持下的数学与3D打印融合研究

Benefits and Challenges:Research on the Integration of Mathematics and 3D Printing with the Support of Design Thinking

教育信息化高质量发展离不开技术促进课堂教学的研究。当前,数学课堂教学在实践中面临着众多障碍,3D打印可用于改善数学教学,设计思维有利于促进该教学方式的创新。基于此,提出“设计思维支持下数学与3D打印融合的设计框架”,并在小学四年级开展数学与3D打印融合的项目,将单组实验研究与个案研究结合,采用定性分析为主、定量分析为辅的方法,探索在我国开展数学与3D打印融合教学的优势与挑战。研究结果表明:数学与3D打印融合的学习过程具有合作性、情境性、操作性、探究性和跨学科的特征,它不仅对普通学生和“学困生”的数学学习有积极的影响,而且有利于促进“问题学生”的行为转变。但是,在我国开展该项目受课时制度和课程内容的限制,且创新教学缺少相对应的创新评价标准。为了促进3D打印技术从“改善”数学课堂走向“改变”数学课堂,通过探索分析,提供了3D打印与数学融合的设计框架与实例,反映了数学与3D打印融合之于学习过程优化与学生成长的价值,并就项目在实施过程中可能遇到的挑战,提出了相应的解决方案。

The high-quality development of educational informatization is inseparable from the study on technology-enhanced classroom instruction.Nowadays,classroom teaching of mathematics faces several obstacles in practice.3D printing(3DP)can be applied in enhancing mathematics teaching,and design thinking(DT)can be utilized to promote the innovation of the pedagogy.Thus,this study proposed“a design framework of the integration of 3DP and mathematics with the support of DT”.We conducted a project which integrated 3DP and mathematics within the students of grade 4.We used a mixed approach containing both experimental research and case study,together with qualitative analysis and quantitative analysis,to explore the benefits and challenges of implementing the project in China.The results show that the learning process of integrated 3DP and mathematics featured cooperation,situation,operation,exploratory,and interdisciplinary.The project has a positive impact on the mathematics learning performance of ordinary students,the performance of students with learning difficulties,and the behavior of underrepresented populations.However,the conduction of the project is limited by the policy of class hours and course content,and it lacks the evaluation standards of innovative instruction.To promote the transformation of the impact of 3DP on mathematics teaching from improving to transforming,this study provided a reference for applying technology in reforming teaching practice by exploring.More specifically,the study provided the design frameworks with the instance of incorporating 3DP into mathematics.The study reflected the value of the project on the optimization of the learning process and the growth of the students.Finally,we analyzed the possible challenges and their corresponding solutions during the implementation process of the project.
