In the past I have found blackboard, although helpful when someone looses the homework, or wants to know what they missed - Blackboard is great.
....not very visual.
This site you will all be invited to participate as part of the class.
• Post your images
• Post your web sites you find interesting
• Pictures that inspire you - etc etc.
The best part of this- is that you will always have access to this site - so over time, if you want to come back to things, or see what another class is doing - you are set.
I hope you find this useful
