Web 2.0 sites become more useful as the number of users grow. Fortunately for teachers, there's loads of free educational 2.0 applications that can be utilized in the classroom to help students research, collaborate and share what they've learned.
Hats off to British educator, Terry Freedman, who has solicited lessons from 94 teachers from around the world and edited them into a free downloadable book Download Amazing Web 2 Projects 2 online version (2 MB pdf) Hint: If you're not following Terry on Twitter (as I do) here's his Twitter link. The book also includes Twitter links to all the creative contributors to the project.
The book is organized by grade level and has curated links to all the web resources utilized. Each project includes a teacher-friendly "how to" with benefits, challenges, management tips, sample screen shots / links and learning outcomes. Terry's project is a great example of how the internet can be harnessed to share and collaborate. Who knows, the projects might even inspire your students to collaborate with their peers on their own book!
