The effects of college grade adjustments on the predictive validity and utility of SAT scores

Regressing adjusted grade-point averages on freshman SAT scores and high school grade-point averages results in large increases in the incremental predictive validity of the SAT. Even so, the SAT still changes no more than a small proportion of admissions decisions and does not result in substantively important increases in freshman grades. The test does, however, change the composition of the freshman class by altering acceptances to some major areas of study and by limiting the access of women and blacks.     

Early Mathematical Growth: How to Support Young Children’s Mathematical Development

The purpose of this critical analysis was to investigate the young children’s sense of numerical magnitudes and the important attributes of classrooms where children in kindergarten and first grade are exposed to mathematics. This study aimed to offer guidelines that will assist teachers as they teach mathematics to children between the ages of five and seven.     

Sexual Health Education in Massage Therapy Programs: A Survey of Program Directors

Massage therapy program directors completed an online survey to explore sexual education in massage therapy programs. The overall data suggest that program directors are supportive of sexual health education in the training of massage therapists and that such education is integrated into several aspects of their training programs. To enhance sexual health education, massage therapy programs could collaborate with specialists in sex therapy or sexuality education. Massage therapy training may need to include the following topics: working with clients who have been sexually abused, working with transsexual clients, understanding sexual arousal processes, and understanding dynamics between men and women.

Specifying a Human Performance Technology Knowledgebase

The mission of human performance technologists, to assure high levels of human performance in organizations, is well established, and usually accomplished through design and implementation of two major products: performance systems and instructional systems. The speed of change in the environments in which HPT is practiced, however, requires frequent analysis of what knowledge and skills are required of HP technologists in pursuit of this goal. This article works backward from results and the products that obtained them, to identify the knowledge, skills, and attitudes that form the critical human performance technology knowledgebase. The author uses an example from our “universal” neighborhood to illustrate seven basic categories of variables influencing organizational performance, and provides examples and non examples of five essential principles of psychology that can help guide HPT practitioners' efforts to design and implement effective systems.
