微课程设计的点链圈(PLC)模型研究

Study on PLC Model for Micro-course Design

随着碎片化资源和草根化媒介技术的出现,微课程成为广大教学工作者和开发人员关注的焦点。但是,目前我国对微课程定义、形成、设计和开发等研究还处于起步阶段,尤其是微课程设计大部分采用线性设计模式,这与微课程自身特点及实施环境是相悖的。鉴于此,首先在文献研究的基础上,提出了微课程的定义,并在"新三论"和学科科学的指导下,提出了微课程的非线性设计模型——点链圈(PLC)模型,并系统地介绍了该模型设计的原理、思路、框架、内容、主要特点及局限性和适应范围。实践证明,这一模型对中小学微课程设计实践具有指导价值,同时丰富和拓展了课程理论和教学设计理论。

With the emergence of the fragmentation of resources and grassroots technology,micro-course has attracted the attention of the teaching staff and developers.However,the study on the definition,design and development of micro-course is still in its initial stage,especially the micro-course design uses the linear design model,which goes against the characteristics of course and the implementation environment.In view of the problems mentioned before,on the basis of literature review,the definition of microcourse is put forward in the paper.Besides,under the guidance of ＂the new three theories＂ and learning science,the nonlinear design model------PLCM（Point,Link,Cycle of model） of micro-course is proposed,and the principle,method,framework,content,main characteristics and limitations and application scope of model design are systematically introduced.It is proved that this model is a reference for micro-course design in the primary and secondary schools,and enriches and develops the theory of curriculum theory and teaching design theory.
