Subjects were more likely to recommend special education programs for normal students when percentile scores were used. School psychologists need to become more familiar with the properties of…

Investigates the remediation of misconceptions through application of Gagne's hierarchical learning theory. Uses stoichiometry, food levels, and conservation of mechanical energy as the target concepts. Reports that there was no treatment effect in analysis of covariance using pretest scores as a covariant. (YP)

Describes a diagnostic evaluation to measure the idea of the living cell as the basic unit of life. Describes the classification of student knowledge as common knowledge, wide-spread lack of knowledge, inadequate alternatives, and contradictions. (YP)
