Enhancing Synote with quizzes, polls and analytics

Videos combined with quizzes and polls are used for educational purposes in many settings, including Massive Open Online Courses (MOOCs) and university lectures. For the authors of these resources, this often involves splitting videos up into sections with a poll or quiz after each section to gauge understanding. This approach requires the author to have video editing skills, and can be time-consuming. It would be useful if quizzes could be created and included directly into videos without the need for video editing. The resulting media could be analysed to discover how best to present information for learning. This paper describes the development of three main tools to Enhance Synote, the web based video annotation System. The Quiz Authoring Tool allows users to specify: sets of questions and polls to appear in the video, the time at which question sets should appear, and actions to be taken when questions are answered (e.g. skip back in the video if the answer is incorrect). The Questions Overlay library to allow quizzes and polls to be overlaid on Web videos in any of the main video formats, playable in the major browsers on different platforms. The Video and Quiz Analytics records and displays metrics of user behavior.
