A learning tool is defined as any software of online tool or service that you use either for your own personal or professional learning, for teaching or training or for creating e-learning. With that definition I was surprised to find that Twitter was the number one Learning Tool, and has been for the past five years. I didn't even know Twitter had been around that long!!! I am shocked; I thought Twitter was perhaps two years old!!! I was surprised that social network only occupies 3 out of the top 10 spots, and that there are two file storage tools in the top ten. Another surprising thing is I have actually heard of half of the top 20 learning tools listed in the article. That is amazing to me. Sadly, however, I haven't heard of much more than that. A few here and there as the list went on, a couple from being in this class, but most of them were not even remotely familiar to me! The fact that shocked me the most is the fact that You Tube was number 3 overall. I go to You Tube to learn about anything and everything. My five children use You Tube for much more than I do when it comes to the "How To" department. So I am most shocked that You Tube was not the number one Learning Tool on this list! It just goes to show that I have a lot to learn when it comes to learning tools on the web!
