Kizoa is a great Web 2 tool to use in the classroom. The students can create slideshows, collage and edit graphics. This is a free tool to use. Once completed the students can save the collage for example to their hard drive (this is not part of the free membership, you need to pay a fee) or share it online through their blog (free). With the slideshows you can put in text, music, animation and other special effects, there are all sorts of possibilities to customize your slideshow! Be careful to only use the free tools and effects if you plan to share your creations.
