"While it was easy for me to find many educational videos on YouTube, I was often hesitant to share them in class or with students because of the ads that appear on the side. These ads were often not appropriate for students, and I resorted to using tools such as ViewPure to filter out extraneous information. Recently, I learned an even easier way to filter YouTube videos. When sharing or using a link for a YouTube video, add a hyphen (-) after the letter 't' in the URL. This small change will make the video ad-free and present the video automatically as full screen." -Karen Leonard, OSDE Director of Educational Technology and Computer Sciences
