Results from this study indicate that a cutoff consisting of the mean plus a half standard deviation is more desirable than the original mean plus one standard deviation strategy for categorizing respondents into a "pure" identity status. Status-specific comparisons indicated groups were not significantly different on measures of…

Presents an activity that allows students to experience the type of discovery process that paleontologists necessarily followed during the early dinosaur explorations. Students are read parts of a story taken from the "American Journal of Science" and interpret the evidence leading to the discovery of Triceratops and Stegosaurus. (PR)

Reports a study to examine the role of context on the ability to interpret graphs. Graph tests involving 2 ecological contexts were presented to 14- and 15-year-old students (n=23) in the form of an interview. Results indicated how students used their contextual knowledge in interpreting the graphs. (MDH)

A proposed solution for the age x cohort x period issue in lifespan research uses all data, even with missing cells; can be used for repeated measures designs or designs in which new subjects are measured at each period; and allows assessment of each main effect and two-way interaction. (SLD)

Asserts that much of research currently conducted in counselor education and supervision is unreliable and invalid. Presents tabulation of research designs and errors in manuscripts submitted to "Counselor Education and Supervision."

Describes a series of 16 longitudinal studies conducted by Utah State University on alternative early intervention programs for disabled children, focusing on the intensity of intervention, the age intervention begins, and parent involvement. Reviews factors that gave rise to the studies, research designs and procedures, and data interpretation.…

The article examines the concepts of power and control in research design and applies them to a review of the validity of three studies (EC 600 064-066) evaluating the effectiveness of using Irlen tinted lenses with reading-disabled persons. Internal validity, external validity, statistical conclusion validity, and construct validity are…

Discusses the need for a revitalization of a scientific agenda for clinical supervision.
