Enhancing Digital Educational Repositories by Linking Videos and Examinations

The last decade has seen significant global efforts to develop and maintain digital educational repositories. Several countries, including India, have created national repositories of high-quality educational videos and related digital content. We have developed a simple open-source tool called ExamLink that allows instructors to enhance such repositories by creating bidirectional links between specific segments of educational videos and specific questions from old examination papers. Our tool exploits such links, allowing students to navigate large video repositories and locate content relevant to particular examination questions, and discover more questions pertaining to the same content. We demonstrate how our tool builds on existing efforts by the National Programme on Technology Enhanced Learning (NPTEL) to create links between question papers for the Graduate Aptitude Test in Engineering (GATE) and videos in the NPTEL archive.
