Interesting article by Deborah Merritt at Ohio State U Moritz College of Law that focuses mainly on the use of PowerPoint but can be applied to other technolgies.
Abstract: Cognitive scientists have made major advances in mapping the process of learning, but legal educators know little about this work. Similarly, law professors have engaged only modestly with new learning technologies like PowerPoint, classroom response systems, podcasts, and web-based instruction. This article addresses these gaps by examining recent research in cognitive science, demonstrating how those insights apply to a sample technology (PowerPoint), and exploring the broader implications of both cognitive science and new classroom technologies for legal education. The article focuses on three fields of cognitive science inquiry: the importance of right brain learning, the limits of working memory, and the role of immediacy in education. Those three areas are fundamental to understanding both the effective use of new classroom technologies and the constraints of more traditional teaching methods.
