It's one thing to talk about Mount St. Helens erupting in science class. It's another thing altogether to watch a video of the mountain's summit exploding into dust. Teachers all across the country are finding that judiciously chosen videos help students engage more deeply with the subject matter, and recall the information they've learned longer.
"A lot of students these days expect information to be presented in a flashy, entertaining way, so videos can help draw them in," says Larry Sanger, executive director of WatchKnowLearn, a site that collects education-related videos. High school student Patrick Greaney still remembers a photosynthesis video he watched in class at Whittier Regional Vocational Technical High School, in Haverhill, Massachusetts, that featured a catchy tune. "The song stuck in my head and made me remember the process better," he recalls.
Though YouTube is blocked in many classrooms because of inappropriate materials on the site, there are many valuable (and downloadable) videos that do further learning.
The site lists an ever-growing collection of excellent educational content, everything from President Obama's weekly addresses to algebraic demonstrations. Here are a few ways to separate the wheat from the chaff:
When choosing clips for the classroom, keep them short. This gives you time to discuss what you've just shown and its significance to the larger lesson. Once you've identified a video, there are several ways to bring it to the classroom.
First, register with YouTube. Set up a video playlist or a collection of favorites, then click them to stream the videos from a laptop. Just remember that YouTube videos are often removed without notice, so the clip you watched at home last night may not be there the next morning. Also, your school or school district might block access to the site.
Many people are tempted to download videos from YouTube to show them in classrooms where YouTube is blocked. According to YouTube's terms of use, you're not supposed to download unless you see a download link, in order to protect video creators’ rights, so you may not want to take this route.
The good news is that YouTube now offers Creative Commons-licensed videos, which are automatically safe to use. You can even modify or edit them into your own videos using the YouTube Video Editor. Enter specific keywords into YouTube’s main search bar as you normally would (“biology lectures,” for instance), then click on the “Filter & Explore” tab to the far left. In the middle of the drop-down list are the words “creative commons.” Click here and all the videos that appear under your search term will be Creative-Commons licensed.
If the content you’re interested in doesn’t come with a Creative Commons tag, it helps to know that the fair use clause in the Copyright Law of the United States allows the use of works without permission for teaching. Still, the user must adhere to some key regulations that can be vague and confusing.
One thing is clear, though: Any material first published after 1978 is copyright protected. You can find the U.S. Copyright Office's educational-use guidelines (PDF) in Circular 21. The University System of Georgia links to a fair use checklist; you can also email the video's maker for permission.
YouTube doesn't typically offer a way to download and save most videos directly. But if you have permission and would like to download from YouTube, there are a variety of ways the resourceful user can download videos:
Some choose to skip YouTube entirely and go to teacher-specific online video sites, of which there are many. SchoolTube is a moderated video-sharing website just for schools. TeacherTube and WatchKnowLearn aggregate thousands of videos from educators, YouTube, and the rest of the Web. In essence, they are clearinghouses of educational videos that cover most school subjects, categorized by subject and education level. WatchKnowLearn has a review panel of educators and educational video experts that vet videos from first-time submitters before posting. SnagLearning is the educational branch of SnagFilms, and offers hundreds of high-quality documentary films to be used as educational tools, sortable by subject or grade level.
Whatever the source, in the end, it's worth the effort. Great content is just a few clicks away.
