I had to go back to Library2Play 23 Things to remind myself how to embed this video. (I had to go back to learn how to screen shot and such, too! That's what I get for not keeping up with my blogging this past year!)
Some of the advantages of having teaching/learning videos available online are:
* You can get ideas from others to try in your own classroom (Like Harry Wong says, "Beg, borrow, and steal")
* A lot of videos find a way to make the learning interesting, fun, and/or memorable which is super important for my middle school students. I always have to think about, "How can I teach this so that they'll remember this in 10 years?"
* Sometimes it's helpful for kids to hear or see a concept in a different way than you've taught it by yourself. Some teachers feel like they should be able to do everything by themselves, and if you're not willing to try something new or let someone else show the same concept in a different manner, you're just setting yourself up for failure.
As for student created work, I think the advantages would be:
* Students are more likely to take pride in their work if they know others will be able to view it. I created a classroom reading blog this last year with my sixth graders, and when they knew that anyone from anywhere in the world could see what they had to say about a book, they thought about it a little bit more than they would if it is was just a pen and paper assignment.
* Students would be able to share their work with family, friends, and the whole world.
* Students would be able to receive feedback from people other than just their teachers.
