HOBOKEN, N.J. - The National Science Foundation has awarded Stevens Institute of Technology and Columbia University a research grant, titled "Externalizing Thought: Improving the design of software through diagrams."
The project seeks to improve software design: We are increasingly dependent on software-intensive systems, said the members of the research team, and "the better they work, the better we work."
Designs of experts are better than those of novices, but it is not clear why. This project will provide new methods for understanding software design expertise and how it develops.
The methods, which involve analyzing diagrams to reveal the cognitive structures of designers, have been developed in other disciplines that rely on sketches and visualizations to realize and fine-tune design. They have not yet been applied to the design of software-intensive systems. A unique and valuable aspect of the project is that it is embedded in a course in design, an opportunity to study design as it happens and to improve design instruction at the same time. The project will also study expert designers practicing in the field.
The Principal Investigator, Jeffrey Nickerson, is an Associate Professor in the Wesley J. Howe School of Technology Management at Stevens Institute of Technology. He teaches a course in the design of information systems that will be studied as part of the project. James Corter, Professor of Statistics and Education at Teachers College, Columbia University, performs research in the area of computational modeling of human learning, including work on visualization in problem solving. Barbara Tversky, Professor of Psychology and Education at Teachers College, Columbia University, is a leading authority in the areas of visual-spatial reasoning and collaborative cognition, and has studied the use of diagrams in a wide range of design activities.
