(From Tomorrow’s Professor). Listen to and Acknowledge Participants - Essential Abilities of Effective Presenters. Two deeply human desires are to be listened to and acknowledged. How we listen and acknowledge contributes much to the quality of our relationships, and how we as presenters listen to and acknowledge participants contributes much to the quality of their learning. As we think about participants in a learning environment, two tensions come to mind. First is their internal tension associated with not knowing or discovering that they don’t know. The second is a self-inflicted tension created when what an individual doesn’t know. What is ironic here is that for learning to take place, tension must be present. The key is not to eliminate tension; rather, it is to manage the tension by reframing it from being associated with emotional threat to being associated with cognitive challenge. When well-managed, the cognitive tension is high and the psychological tension is low. The safe learning environment is a state of relaxed alertness.
