Ong, W. (1982) Orality and Literacy: The technologizing of the Word. Routledge, London and New York.
I highly recommend this resource as it delves deeply into examining the differences between oral and literate based cultures. The major critiques of the book centre around the literary deterministic tendencies of the book. The author also states the incredible challenge of examining oral based cultures from the perspective of a literate researcher. However the strengths of the book centre around providing the educational technologist a perspective on attributes and ways of thinking and remembering of more orally based cultures. Understanding the differences can support and enhance instruction.
