This came from one of the blogs on my google reader. I love how this article takes a current event and compares it with a historical event in order to further discuss and clarify what is happening today. Sharing things like this with your students can help show why history is relevant.
This is a great website for future and current history teachers. I love that it provides links to other online sources that can help everyone find what they are looking for. This specific page is just about getting started, but there are links and sources all throughout this website.
Catherine posted this great resource to "blogging for dummies"--helpful for people who are new! We'll have to see if this person keeps updating their site.
