In 2009, Mike and I started to build a "webquest" based on 21st Century skills. It has come a long way, as each year it changed and more technology was added. We added Computer Side Chats with google forms, then Diigo group sharing, Google doc collaboration between different schools, edpuzzles, etc.. And this year, added Historical Tweets!
It is important to remember, I have control of what is tweeted under my name.
Overall, I am happy with the results. I will look a little deeper into where I got this form and update this post with a link.
