Methodological Limitations of the Application of Expert Systems Methodology in Reading.
Willson, Victor L.
Methodological deficiencies inherent in expert-novice reading research make it impossible to draw inferences about curriculum change. First, comparisons of intact groups are often used as a basis for making causal inferences about how observed characteristics affect behaviors. While comparing different groups is not by itself a useless activity, progressing directly to training is premature at best. Second, the think-aloud protocol technique is often used for inferring a subject's cognitive structure of subject matter. This method is inappropriate because it assumes that the organization of this structure resides consciously in a person's mind and can be verbally reproduced. Third, retrospective methods have been employed to infer causality by selecting groups currently differing and discovering differences in their past on putative causal variables, which are then inferred to have caused the present differences. While this technique must be used in historical analyses, it becomes suspect when the inferences are used to speculate on implications for current practice. Finally, techniques employed in naturalistic inquiry often confuse a change in methodology with a change in the discipline being studied, and rely heavily on impressionistic, one-shot observation for many facts.
