I’ve been playing on (with?) a new resource for learning and teaching called SocialLearning.ca 
You can learn a lot on this site. For direct learning, take a look at the Tutorials section – the link is on the far right on the navbar at the top.
You can also learn by exploring a little using the (right)sidebar to click on tags or other links –
And finally, you can learn by exploring the navbar at the top. For example, by clicking on “Software” you will find information on various software that SocialLearning.ca members recommend and/or describe.
If, as a teacher, you have trouble filling your time during the summer (;-> irony alert!) you could spend at least some of your “free” time exploring and learning from this site.
