I kept seeing this being tweeted for about a week now and finally had time today to click on the link and read the article. Every teacher needs to read the post "Top 20 Websites No Teacher Should Start the 2010-2011Year Without" by Samantha Smoke. She has written about tools that every teacher should know about and be adding to their toolbox.
I know that using Web 2.0 tools can seem overwhelming, but I encourage every teacher to try out one new tool each month this school year. Remember that you don't have to be an expert with the tool to begin using it. Just play around with one at a time and have fun. A strategy I use is I use the tool a little bit and then introduce it to my fourth graders and challenge them to learn more about it. I give them time in class to demonstrate their expertise and we all benefit.
Let's start 2010-2011 off on the right foot by learning together.
