Using Video Lectures in E-Learning Platform to Improve Physics Teaching at University Level

Work in Progress: Real-Time Annotations of Video-Lectures

“…The practice of recording lectures and making them available via web, either in open form or with protected access in a Learning Management System, is obviously useful for students who cannot attend classes. However, it has been demonstrated that even students who were in class use the videos to selectively review portions of lectures, for instance for checking their notes, clearing some doubts, resolving interpretation conflicts with their peers [8,9].
