I was just looking on Pinterest and I came across this fantastic image of 21 Things Every 21st Century Teacher Should Do This Year. It is a list compiled by Sean Junkins from this blog post by Mr Hooker. (so much linking around!) The blog post is really good and gives a description and example of each idea.
The ideas are all technology based and show ways in which we can use technology in relevant and educational ways. I want to try so many of these ideas now! They seem very simple to do and effective as well.
