This document discusses using Twitter for teaching and learning. It provides examples of how teachers can use Twitter to prepare for lessons by getting feedback on ideas from other teachers, engage students during class by having students tweet questions and comments, and facilitate reflection after class through linking tweets to blogs. While some argue teachers don't have time for Twitter, the document counters that it doesn't require constant connection and can be used in ways that fit any schedule. By making resources and discussions accessible via Twitter, teaching and learning can continue beyond the classroom.
