25 Ways to use Twitter in Education
Edudemic Magazine has put together a handy guide of 25 ideas to incorporate Twitter into the classroom, called "The Twitter Spectrum for Educators" - from easy to most difficult. The guide ranges from "watch" to "talk" to "produce" - so that classes can ease into Twitter gradually. A great feature of the guide is that each idea starts with a verb, a la Bloom's Taxonomy - so that you can look at your course learning objectives and find good potential matches to meet your objectives. If you've been toying around with giving it a try or looking for ideas to enhance your course by immersing students into a larger (world-wide) community of learning, research, and/or practice, check out the guide, and then contact your instructional designer to plan and implement.
