Hi Cynthia: Personality and delivery can both contribute to effective instructional periods. Assessing how students learn and using diiferent approaches to teaching a class is likely to produce better retention. An old saying: "to a hammer, everything is a nail". So my personal preferences in delivery are not as important as how best I can meet student learning needs, even if I use methods that arn't my prefered choice. But if I'm sincere and care, students will appreciate my authenticity. Regards, Barry
