Abstract

Examines differences in cognitive activities and final designs among expert designers using object oriented and procedural design methodologies, and among expert and novice object-oriented designers, when novices have extensive procedural experience. A closer alliance of domain and solution spaces in object-oriented design was observed compared to prcedural design. Procedural programmers spent a large proportion of their time analyzing the problem domain. In contrast, object oriented designers defined objects and method much more quickly and spent more time evaluating their designs through simulation processes. Novices resembled object oriented experts in some ways and procedural experts in others. Their designs had the general shape of the object oriented experts design, but retained some procedural features. Novices were very inefficient at defining objects, going through an extensive situation analysis first, in amanner similar to the procedural experts. Some suggestions for instruction are made on the basis of novice object oriented disigners' difficulties
