Towards Ubiquitous Knowledge Management: Design and Adoption of A Cloud-Based Dynamic-Video-Note Service for MOOC Platforms

Keeping notes can be seen as the process of the extraction and re-creation of fine-grained knowledges, i.e., knowledge innovation. It is an important learning method for MOOC learners, while there are little efforts in favoring their note-taking behavior upon watching course videos. In this paper, we summarized the limitations of existing note services provided by popular MOOC platforms and proposed a prototype of a cloud-based dynamic video note service for diverse MOOC Platforms. The new service utilized the idea of bulletin comments for personalized real-time note rendering upon MOOC videos, based its architecture on cloud microservices for ubiquitous video note management, lied the basis on the knowledge collaboration theory for socialized knowledge innovation, and performed big-data analysis for learning process evaluation. Evaluations based on running instances and a questionnaire survey proved the effectiveness of the protype.
