Yesterday we added question suggestions to oodlu.org. Question suggestions make it quick and easy to find content on oodlu.org by suggesting other similar questions to those that you are typing in.
Today we added a couple of tiny enhancements which make this even more powerful. A refresh button and a "suggest similar" button for each question which enables you to get more specific suggestions.
Here is how it works:
We will be extending this functionality over the coming weeks to enhance search and suggest entire question collections based on what you have been using. This should make it easier than ever to use oodlu.org in your classroom.
Oh, and this is free by the way ;)
