Regarding the finding that "models that emphasize basic skills produced better results on tests of self-concept than did other models", the authors question the efficacy of the self-esteem measures; implying, among other things, that young students cannot possibly have a concrete understanding of self-concept (pp. 138–139). While the article intended to review the operational design of the "Follow Through" evaluation, instead it appears to (1) refute the finding that cognitive-conceptual and affective-cognitive models were largely failures, and (2) unilaterally condemn the models that emphasize basic skills. The implication is that the goal of education should not be increased student achievement in solely basic skills, and that "Follow Through" would have been better employed to discover how measures of all three orientations could be made successful. Absent from the critique is the finding that, for third graders, only the Direct Instruction model demonstrated positive effects in all three domains, and that one of the remaining two models (Behavior Analysis; the other was the Parent Education model) that had positive effects in at least two domains was also a self-described "basic skills model".
