In order to prepare students to work on a pre set exam question based on two readings, one from Kreps (Ch 23 Credibility and Reputation, Micro for Managers) , the other from Dixit and Skeath (Games of strategy – 10 steps to credibility!) . This was done “impromptu” , using a document camera – but as it turned out the “slower” pace of hand written material “works” well. Maybe better than regular “pre prepared, slick, presentation slides”?
