I blogged about Glogster a while ago but this new distinction is worth sharing with you. Glogster is a "keeping it simple" tool and the EDU version for teachers offers many free benefits. Glogster EDU offers a premium membership but I suggest you try and explore the free version first before you upgrade.
Here is a get to know Glogster EDU link. http://edu.glogster.com/what-is-glogster-edu/
and a 5-minute video tutorial on using Glogster EDU.

Now that you know a bit more, perhaps you are already thinking about how you can use Glogster with your students/class. Here is a list of 20 ideas but the most important thing to remember is that Glogster supports student creativity and engagement, is easy to learn, and can be used in any subject.
Since DEN members voted it #1 site, I hope you will check it out and register for a free membership. Post a comment if you already use Glogster EDU to have your students create glogs.
