I have heard and shared information about Edcanvas the other day on my social media. It is a free service for teachers to organize and share materials in a simple way and interesting format. The “canvas” is where you can attach and arrange various ranges of materials, including videos, images, links, uploaded files of any topic you create. You can also search materials using different services without leaving the site.
I think it is important to plan a brief story flow for your “canvas” so they will be in a good order. Then you can locate relevant materials and simply drag and drop them in the template you choose. When you finish, you can embed into your blog or share in many platforms, including Edmodo, Facebook, Twitter, Blogging services, etc. You can also set up a QR for your canvas. I think it is similar to MentorMob.
I just played around recently and here is one of my creations: Ice breakers for ESL/EFL on Edcanvas. Have a look!
