I found this site today. What a great tool! It is called the Teaching Channel and it is really cool. It gives short videos usually between 1-20 minutes in length about all kinds of topics. It gives you a place to keep notes in the video, with a time stamp, gives questions to consider in using the techniques or video in class, and gives you online work space to keep all of the information you collect.
Better still, the site gives you a button to put on your tool bar so that if you find something on the Web that you would like to use in a lesson, you click on the button and it saves it for you in your account for future use. You can even schedule reminders in your account; suppose you find a site in September, but the timing to use it isn't until November. Schedule a reminder for yourself! No more searching through bookmarks!
(There's a sample video below...yes, they allow you to embed their stuff on to your website or blog too, and all of it is FREE!)
I'm just learning all of the details, but what I've experienced so far, I recommend trying. There are some great ideas for all topics and they are looking to add more.
Check it out!
