ISSUU.com is great tool for sharing class books or individual student projects. You simply create a free account, upload a pdf, and your digital book is born! To share, you can get a direct link, share via many different social media sites, or embed it on your website.
I use this site frequently to share class books (where you may only have one copy, but you'd like to send it to all parents), or to an audience that is not in our area. Here is an example of a class book 1st graders wrote after their landform research (they typed and added the photos themselves):
Here is another example of a class book kindergarten students created after visiting with author Jennifer Ward:
I've used this tool with other students as a way to elicit feedback from others. They upload a pdf of their draft to our class blog, and everyone is able to view it at the same time. They can tell each other what they like about their project and any suggestions for improvement. It is powerful to get peer feedback and it easily done digitally. Here is a sample of a 5th grade project, where students did research and created their own "Who Would Win Books" based on Jim Pallotta's series. Then, they uploaded it to issuu, and shared it with their classmates for feedback, giving everyone a voice!
ISSUU is a simple, but very effective tool. How have/could you use it in your classroom or library?
