Twiducate is more than just a cool tool for bookmarking links, important dates and posting homelearning etc.
The other week I used it with my class in, what I think, was a real neat 21st century way. We had been having some discussion around what "culture" means. I got my kids in groups of 3 and they logged onto our class twiducate account. I then posted the question to the class, "What does the word "culture" mean to your group?
All groups posted their replies back to me, and as a class we went over them using the data projector. I then asked them, in their groups again, to use the "like" button to indicate which of the group definitions they thought was the "best" answer. Again, using the data projector, it was clear that one particular group's definition was the clear favourite amongst the class, having the most "likes" From there, as a class, we further developed this particular definition to arrive at a whole class shared definition of what "culture" is.
It was alot of fun and most kids were fully engaged for the duration of the activity :-)
