What is EduCanon?
eduCanon is an online learning environment to create and share interactive video lessons. Teachers begin with any YouTube, Vimeo, or TeacherTube video content (screencasts, Khan Academy, Minute Physics, TED, NOVA, etc.) and transform what is traditionally passive content into an active experience for students. By time-linking activities that students engage with as the video progresses the content is segmented into digestible components - increasing student engagement and, through our real-time monitoring, informing the next day’s lesson planning.
You can use it to learn English too! Browse the website and you'll find the category "English", which contains subcategories such as grammar, spelling, reading, writing, pronunciation, etc.
