Effects of the orientation of knowledge maps on learning were studied with 28 undergraduate students who were randomly assigned to study maps presented vertically or horizontally. Performance of high and low vocabulary subjects was evaluated. Low vocabulary subjects who used linear maps performed more poorly than any other group. (SLD)

This study illustrates a process for selecting a preferred model in the validation of hierarchical learning scales. The test performance of 100 8-to 11-year-old children on subtraction tasks involving variations in borrowing are examined. Goodman's response scaling technique is illustrated. (Author/GDC)

Six hundred twenty-six subjects from the University of Arizona participated in an investigation designed to examine congruence of a math domain hierarchy validated psychometrically and validated instructionally. Three studies revealed congruence between hierarchies validated psychometrically and instructionally. Generalization and transfer were…

White and Gagne's method (EJ 180 555) for formatively evaluating learning hierarchies does not require participants to be taught the content prior to testing them for their knowledge of the skills in the hierarchy. By simply determining the percentage of students achieving each skill, the researcher obtains approximately the same information.…

This study investigated the hypothesis that prerequisite skills in a seriation learning hierarchy mediate positive transfer for superordinate skills. In addition, the effect of instructional conditions involving modeling combined with variations in feedback on skill acquisition at different levels in the seriation sequence was examined.…
