Why use Google Docs instead of Word or paper?
Google Docs allow for collaboration and interactive learning. Through Docs you can:
Collaborate with others - without needing to sit in groups or be anywhere near one another.
Create HyperDocs - interactive documents that ask students to go beyond just typing out answers by incorporating a variety of learning modalities, asking students to check for understanding along the way, and build critical thinking skills
provide immediate feedback on student work
peer editing with guided support - link to other resources, spelling and grammar info, examples of correct answers directly from student work
HyperDocs are a great way to add interaction and additional levels of critical thinking and student interaction to your lessons.
