The format allows for continual additions and organic like growth as you are not confined to one page.
You can add several types of media files (image, audio, video)

Cons
High Learning Curve
Needs to be more teacher centred as it is unlikely students at this level will be able to create their own Prezi
Cannot Print Handouts
