I'm always looking for interesting free tools for multimedia project work and I recently stumbled across a very nice one called Museum Box. It describes itself as providing 'the tools for you to build up an argument or description of an event, person or historical period by placing items in a virtual box".
To use the site you need first to collect up your various media. You can upload videos , images , audio files, collect links and add documents.
All of these are uploaded to sectioned boxes, and each section of the box is a cube with 6 sides to which you can add your media.
When the box is finished you can publish and share the results and users can view the different sections of the box.
I think this is a wonderful idea and a great way of publishing your students' work. There are already quite a collection of boxes on the site, which students might find interesting.
The projects don't have to be historical, you could create a box with a section for each member of your class, or students could create boxes about their local city or environmental problems.
Hope you enjoy this and find it useful.
