Extensive use of video to support teaching and learning has become a trend. Unlike traditional ways to disseminate subject content from teacher to students, video technology is now used to support active and collaborative learning. Students and teachers can both create and share content online, add interactive elements, personalise the video with annotations and bookmarks, and to initiate asynchronous discussion inside video clips. At The Hong Kong Polytechnic University, resources and efforts are dedicated to facilitate and support the use of video extensively in teaching and learning. A series of workshops is provided to academic and support staff on the pedagogical and operational aspects of adopting video to enhance learning and teaching, complemented by intensive instructional and technical support for pilot runs. Advanced applications of video are being reported by teaching staff members, e.g., the use of databanalytics to track student engagement and behaviour, and to implement contingency plans to tackle unexpected class cancellation.
