Spinal reflexes: Using mini whiteboards 

In this brisk five-minute activity, the teacher, Keith Moore, checks learning of key points at the completion of a series of sessions on spinal (automatic) reflexes. He poses a question relating to spinal reflexes, and each learner writes an answer on a small wipeable whiteboard. He then checks learning and gives feedback on their responses.

Consider
What are the advantages of using the whiteboards to check on learning?
How can your learners be more active in any of the short activities that you use?
How could you plan this technique into your own sessions?
