There is not just one way to give feedback, nor is there just one kind of feedback. Bug-in-ear technology, which allows coaches to give teachers in the classroom immediate feedback, has been used successfully for 35 years. In an updated twist on this method, researchers at the University of Kansas used bug-in-ear coaching in a virtual classroom called TeachLivE to give four secondary teachers a chance to practice providing feedback to students. Studies in the last 35 years have shown the positive effects of using bug-in-ear technology to assist teachers with explicit instruction, delivery of feedback, opportunities to respond, and classroom management. Three benefits stand out: (1) Immediate feedback has a significantly positive effect on instructional practice, regardless of the amount of teaching experience; (2) Overall, participants using wireless technology to give or receive feedback react positively; and (3) Students react positively to teachers' improved instructional practices.
