Two selection and nine evaluation hypothesis testing tasks varying systematically with respect to causality, response alternatives, and context continuity were administered to two samples of adults (N=35; N=32). It was to determine effects of these variables and the degree to which subjects reasoned with material conditional, biconditional,…

Examines successful/unsuccessful distinctions between novices and experts in problem solving in terms of genetic knowledge, use of production rules, strategy selection, use of critical cues, use of logic, understanding of probability, and the thinking process itself. Suggests five implications for genetics instruction and provides three problems…

College students (N=52) were given unfamiliar or novel problems (written and interview responses) to determine how they characterize living things, criteria they use to distinguish between living/dead/nonliving, and to determine if their idea of life included the interrelationship between organisms and biosphere. Results and implications are…

Investigated is the extent to which students' nonscientific beliefs change by comparing before and after instruction as a function of students' reasoning skill. Nonscientific beliefs discussed include special creation, orthogenesis, the soul, nonreductionism, vitalism, teleology, and nonemergentism. (KR)

The cognitive factors that contribute to competence in the biological sciences were examined. The role played by cognitive style and analytical ability is discussed. The ability to abstract relevant information, evaluate it, and use it is affected by the skills of analysis and cognitive style. (KR)

Assessed the effect of a one-semester college biology course on the development of students (N=72) ability to reason formally and interactions among intelligence, cognitive style, and cognitive level. Includes implications for science instruction. (SK)

This manual was developed to provide guidance to individuals working in Project SOAR (Stress on Analytical Reasoning), a pre-freshman summer program for science majors anticipating matriculation at Xavier University of Louisiana. Following an overview of Xavier University and Project SOAR and an outline of general instructions, specific…
