虚拟切片的网络课程碎片化资源设计

Research of Fragmental Design of Learning Resources of Network Courses Based on Virtual Slices

传统的网络课程因资源粒度过大、时间过长难以满足学习者微型化、碎片化及个性化的学习需要,本研究通过分析碎片化学习资源特点及其认知特性,从碎片化学习资源设计、技术开发及实现方式三个维度,提出了网络课程的碎片化学习资源的"拆解"与"重构"设计开发模式。利用虚拟切片技术拆解并重构了从知识碎片化到知识单元与知识主题的结构化研究。以"C程序设计"网络课程为例,开展了碎片化学习资源设计的案例研究,对其学习方式与传统的课堂学习方式进行了比较。研究表明,碎片化学习资源可以更好地满足学习者微型化、碎片化及个性化的学习需求,完善知识结构与夯实知识水平,及时弥补传统学习方式中的不足,提高学习者的学习绩效。

Traditional network curriculum fragmentation personalized learning resources are very large and cannot meet the needs of miniaturization, In this study, by analyzing the characteristics and cognitive style of fragmentation learning resources, the design model of the dismantle and reconstruction of the fragmentation learning resources based on high-quality courses is proposed from design strategy, technology development and implementation. The structure of knowledge is dismantled and reconstructed from knowledge fragmentation to knowledge unit and knowledge topic by virtual slice technology. As an example,＂C programming＂ course was fragmented. A comparative study of learning style was analyzed in detail between fragmented learning and traditional classroom learning methods. This study showed that the fragmentation of learning resources can better meet the needs of learners in miniaturization, fragmentation and personalized learning, improve learner＇s knowledge structure and strengthen the knowledge level, It can compensate the shortcomings in the traditional way of learning and improve the learner＇s learning performance.
