At Grace E. Metz Middle School in Manassas Va., students use hand-held devices called "clickers" to prepare for state tests. Educators who have used them say clickers help involve every student in a lesson and give teachers immediate feedback about what students are learning, so that instructional strategies can be changed on the fly.
What role do electronic learning devices play in your school? Do they help students or distract them? Should schools invest more or less in learning technologies in the future?
