Discussed are some of the uncertainties in human genetic mechanisms that are often presented as dogma in Biology textbooks. Presented is a brief historical background and illustrations involving chromosome abnormality in humans and linkage studies in humans. (CW)

Discussed is learning theory as it is related to the teaching of biology. This article proposes that extension of the original cycle model into three types of learning cycles can form the basis of a satisfactory and educationally practical model of instruction. Includes 30 references. (CW)

Examined knowledge, attitudes, and opinions of 60 older adults about cardiopulmonary resuscitation (CPR). Most had little or no accurate knowledge of CPR. Knowledge deficits and misconceptions of older adults should be addressed so that they may become informed and active participants in CPR decision-making process. (BF)

The National Center for Educational Leadership, a consortium of Harvard, Vanderbilt, and Chicago universities, was federally funded to develop and disseminate knowledge to improve educational leadership quality. This article summarizes the panel's deliberations, highlighting three issues: leadership effectiveness, administrator preparation, and…

The U.S. educational community must reexamine its underlying cultural perspectives and assumptions and develop an awareness of the varied cognitive styles, behavioral norms, and value systems represented by students. To build a creative, peaceful, and productive multicultural society, we must rethink multicultural models, knowledge construction,…

Explains many well-known problems associated with trying to correlate "intelligence" measures with measures of "race," such as reification, circular arguments, biological definitions of race, comparison of individual and group differences, correlation versus causation, intelligence quotient heritability, and ideology/social…

Administered questionnaires to 35 science teachers to test the hypotheses that teachers holding constructivist beliefs are more likely to detect alternative conceptions, have a richer repertoire of teaching strategies, use more effective teaching strategies for inducing conceptual change, and report frequent use of effective teaching strategies.…

Recent incorporation of a performance assessment in Arizona's test mandate provides an opportunity to examine the assumptions and beliefs underlying measurement-driven reform. Efforts to meld cognitive-constructivist beliefs about pupil learning and assessment contradict behaviorist beliefs about changing teachers and reforming schools. Mandates…

Common misconception is that only heroic, authoritative people can alter normal flow of a school or district to ensure all students learn successfully.

Special education is under fire from within and without. Full inclusionists and detracking advocates want to abolish all "separatist" special education settings and "unjust" disability categories, tests, and placements; politicians and school administrators deplore special education's high costs. However, mainstreaming efficacy…

Investigated a microcomputer-based system for the diagnosis and remediation of three Aristotelian alternative conceptions of force and motion held by eighth-grade physical science students. Reports that computer simulations exemplifying canonical conceptions facilitate alteration of students' naive conceptions to a significant degree. Suggests…

Described a probe that can assess the learners' understanding of scientific ideas in conditions that do not demand closure on a single interpretation, and where learners can demonstrate certainty or otherwise in several possible alternatives. Can be used in monitoring conceptual change when intuitive understanding of scientific phenomena is to be…
