A Closer Look into Recent Video-based Learning Research: A Comprehensive Review of Video Characteristics, Tools, Technologies, and Learning Effectiveness

People increasingly use videos on the Web as a source for learning. To support this way of learning, researchers and developers are continuously developing tools, proposing guidelines, analyzing data, and conducting experiments. However, it is still not clear what characteristics a video should have to be an effective learning medium. In this paper, we present a comprehensive review of 257 articles on video-based learning for the period from 2016 to 2021. One of the aims of the review is to identify the video characteristics that have been explored by previous work. Based on our analysis, we suggest a taxonomy which organizes the video characteristics and contextual aspects into eight categories: (1) audio features, (2) visual features, (3) textual features, (4) instructor behavior, (5) learners activities, (6) interactive features (quizzes, etc.), (7) production style, and (8) instructional design. Also, we identify four representative research directions: (1) proposals of tools to support video-based learning, (2) studies with controlled experiments, (3) data analysis studies, and (4) proposals of design guidelines for learning videos. We find that the most explored characteristics are textual features followed by visual features, learner activities, and interactive features. Text of transcripts, video frames, and images (figures and illustrations) are most frequently used by tools that support learning through videos. The learner activity is heavily explored through log files in data analysis studies, and interactive features have been frequently scrutinized in controlled experiments. We complement our review by contrasting research findings that investigate the impact of video characteristics on the learning effectiveness, report on tasks and technologies used to develop tools that support learning, and summarize trends of design guidelines to produce learning video

MultiEdTech 2017: 1st international workshop on multimedia-based educational and knowledge technologies for personalized and social online training

Educational and Knowledge Technologies (EdTech), especially in connection to multimedia content and the vision of mobile and personalised learning, is a hot topic in both academia and the business start-ups ecosystem. The driver and enabler of this is on the one side the development and widespread availability of multimedia materials and MOOCs, which represent multimedia content produced specifically for supporting e-learning; and, on the other side, the ever increasing availability of all sorts on information on the Internet and in social media channels (e. g. lectures, research papers, user-generated videos, news items), which, despite not directly targeting e-learning, can prove to be valuable complements to the more targeted learning materials. Although the availability of such content is not a problem these days, finding the right content and associating different relevant pieces of multimedia so as to enable a comprehensive learning experience on a chosen subject is by no means a trivial task. This workshop provides research in areas related to multimedia-based educational and knowledge technologies and particularly on the use of multimedia search and retrieval, analysis and understanding, browsing, summarisation, recommendation, and visualisation technologies on multimedia content available in specialised learning platforms, the Web, mobile devices and/or social networks for supporting personalised and adaptive e-learning and training
