One of the most popular posts on this blog is the one on online whiteboards which has been updated recently. Using Screenr recently I was reminded how well it works. It is also possible to easily upload a Screenr screencast to YouTube.
This was part of some feedback on a homework task (Tethered Goat – see nrich version here).
The video has been uploaded to our class wiki (I use Wikispaces).

The wiki page includes advice on the features of a great solution, some questions for reflection and some images of student work.
