The issue of complexity, as applied to the way we gather information and learn, is a hallmark of this information age. The sheer amount of data, in addition to the increasingly technological way in which the data are delivered, have had profound effects on the ways in which we process information and, hopefully, learn. In this cutting edge volume, Wayne Reeves, a professor as well as consultant to Sun Microsystems, provides an overview of the field of complexity (including chaos theory, information literacy, and Knowledge Management Tools) and presents a working framework to help guide further research. Aimed particularly at researchers, professors, and students in the areas of cognitive science and library//information sc

Evaluating Cognitive Complexity

Evaluating cognitive complexity

Cognitive tools, on the whole, are information-based tools, ones with interior representations and for which the design problems are complex. There is no folk design for cognitive artifacts…. Cognitive tools are simply harder to get right.

—Donald Norman

The design of “cognitive tools” is harder to get right! This chapter is about creating a unique set of evaluation methods capable of measuring the effectiveness of LCD in order to get it right. As we move through the chapters of Part II, we will elicit a series of design principles, some quite old, others new, based on some aspect of research in cognitive or information science that specifically attacks cognitive complexity (CC). Some of the guidelines will help manage complexity by aligning with ...
