Center node: "expert programming knowledge a schema based approach"
  Abstract: The topic of this chapter is the role of expert programming knowledge in comprehension. 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 that support schema-based models of understanding are presented. Data that are more consistent with the ‘control-flow approach’ suggest limitations of the former kind of models.
