Abstract

AbstractThe purpose of this simulation study was to compare the judgments on 12 schoolteacher performance dossiers by a computer expert system with similar decisions by human experts reported in a previous study. An expert system contains questions, rules, linked advice, and an organizing logic. Both promotion decisions and ranking of dossiers by quality were included in the comparison. The expert system showed high levels of agreement with the human judges. This finding suggests that the computer knowledge base is useful for understanding the difficult task of determining teacher quality. Practical implications suggest that teacher evaluation requires complex and extensive data gathering. Support is provided for the theoretical view that teaching quality is a complex and variable phenomenon.
