Abstract
This paper discusses the reengineering of an executive MBA economics principles course. Traditional lecture-test structure was changed to a seminar style. Events leading to this change are described. Many years of evaluation results are presented to quantitatively and qualitatively depict the dramatic impacts of the changes. Learning theories that help explain the effects are then discussed, especially as they may help others redesign their teaching methodologies. Non-theoretic learning strategies for students and seven research-based principles for more effective teaching are also presented to help explain the results achieved.
