Expert Programming Knowledge: a Schema-Based Approach

Abstract

The topic of this chapter is the role of expert programming knowledge in the understanding activity. In the "schema-based approach", the role of semantic structures is emphasized whereas, in the "control-flow approach", the role of syntactic structures is emphasized. Data which support schema-based models of understanding are presented. Data which are more consistent with the "control-flow approach" allow to discuss the limits of the former kind of models.
