MERLOT is a curated collection of free and open online teaching, learning, and faculty development services contributed and used by an international education community. Includes video tutorials, learning exercises, and more.
This platform also allows users to take any useful educational video, not just TED's, and easily create a customized lesson around the video. Users can distribute the lessons, publicly or privately, and track their impact on the world, a class, or an individual student.
Free, downloadable software that will capture videos or screenshots. You can download images, but the videos go directly online with a link to them. Jing opens automatically when you start your computer and will appear as a yellow "sun" on your desktop. It's excellent for making "quick and dirty" tutorials.
