Peer reviewedNesbit, John C.; Hunka, Steve – Instructional Science, 1987
Proposes a criterion for selecting a sequence of objectives from a learning hierarchy and describes a sequence generating algorithm which is designed to generate a minimal memory load sequence from a learning tree. Its effectiveness in generating low memory load sequences from hierarchies that are not trees is also discussed. (RP)

Peer reviewedCarter, Carolyn S.; And Others – Journal of Research in Science Teaching, 1987
Reports on a study in which two spatial tests were given to science and engineering majors and to students in nursing and agriculture at Purdue University (Indiana). Scores from the tests consistently contributed a small but significant amount of success on measures of performance in chemistry. (TW)

Peer reviewedPribyl, Jeffrey R.; Bodner, George M. – Journal of Research in Science Teaching, 1987
Reports on a study which examined the relationship between spatial ability and performance in organic chemistry. Results indicated that students with high spatial scores did significantly better on questions requiring problem solving skills, as well as on those requiring the mental manipulation of two-dimensional representations of a molecule.
