Traditional classroom model, a teacher asks a question, and the kids who are more quick to answer will have their voices heard. Those who need to think, don’t like to talk in class, etc. won’t get heard.
Using plickers gives a way to give a voice to everyone in the class. It records in real time what students think about a question that is posed. It will help me guide my teaching to give more practice to concepts that aren’t mastered, and move on from the ones that are mastered.
