新工科背景下的大学物理PBL教学:以刚体的动量矩守恒定律为例

THE COLLEGE PHYSICS TEACHING UNDER THE BACKGROUND OF EMERGING ENGINEERING EDUCATION AND PBL:TAKING RIGID BODY'S LAW OF CONSERVATION OF MOMENT OF MOMENTUM AS AN EXAMPLE

新工科的建设目标要求为新经济培养新型复合人才,基于问题/项目的学习(Problem/Project Based Learning,即PBL)被认为是一种能够调动学习积极性,同时能够激发及培养学生创新能力、多学科融合的教学方式。在大班授课模式下引入"互联网+"实施PBL,使受空间和时间限制的PBL活动通过网络实施成为可能。本文以大学物理中刚体的动量矩守恒定律为例详细讨论了如何在实际授课中通过"互联网+"和课堂教学活动实施PBL。研究结果表明,"互联网+"为教学实施PBL提供了课堂的拓展途径,成为课堂的有效延伸,进而为培养新工科人才奠定基础。

The construction goals of the emerging engineering education(3 E) require the development of new types of compound talents for the new economy. Problem/project-based learning(PBL) is considered to be a teaching method of integration of multi-disciplines to mobilize the enthusiasm of learning while stimulating, cultivating students' innovative abilities. Implementation of PBL combining the "Internet+" in the large-scale class teaching mode makes it possible to implement PBL activities,which are limited by sapce and time, through the Internet. By taking the law of conservation of moment of momentum for rigid body as the example, how to implement PBL through "Internet+" and teaching and learning activities(TLAs) in actual class is discussed in detail. The research results show that "Internet+" provides the expanding approach of classroom for PBL implementation in TLAs and becomes an effective extension of the classroom. Further more, they would be the foundation for the training of 3 E talents.
