Activities in which students explore the fundamental reasons behind the unusual instability of the trans isomers in medium-sized cycloalkenes by using the results of molecular modeling are described. Exercises have been proposed to explore the structures of cycloheptene and cyclooctene by Hehre and others which would be helpful to disabuse…

The misconceptions of students who are inspired and confused by the films and television program they see are presented. However, there are some good opportunities to engage students and encourage greater understanding and interest.

The suggestion that coherent motion may serve as a test of magnocellular sensitivity is problematic. However, the nature of the problems depends on how the "magnocellular system" is defined. If this term is limited to subcortical entities, the problems are that subcortical neurons are not directionally selective, and that their receptive fields…

M. Pena, L. L. Bonatti, M. Nespor, and J. Mehler (see record 2002-06215-001) argued that humans compute nonadjacent statistical relations among syllables in a continuous artificial speech stream to extract words, but they use other computations to determine the structural properties of words. Instead, when participants are familiarized with a…

L. L. Bonatti, M. Pena, M. Nespor, and J. Mehler (see record 2006-06642-010) argued that P. Perruchet, M. D. Tyler, N. Galland, and R. Peereman (see record 2004-21166-008) confused the notions of segmentation and generalization by ignoring the evidence for generalization in M. Pena, L. L. Bonatti, M. Nespor, and J. Mehler (see record…

The authors make 3 points in response to F. Schlaghecken and M. Eimer's (see record 2006-09007-009) proposal of self-inhibition as an explanatory factor in the negative compatibility effect: (a) The self-inhibition hypothesis lacks empirical support for its main tenets; (b) considering the roles of geometric, spatial, and temporal similarity of…

There are significant misconceptions within the chemical community and molecular science, particularly in the undergraduate curriculum and the associated textbooks. Some of the misconceptions are described, which give poor basis to understand molecular bonding and structure, and reaction mechanisms.

The situations created by individual style of problem solving in mathematics by children are discussed. Children can solve their mathematical problem by correcting their misconceptions on their own with the use of open discussions with others.

Children form their own ideas, which become their beliefs based on their experiences. The misconceptions prevailing within children are stated with the measures to guide them to examine their ideas.

The nation continues its ceaseless struggle with the spiraling cost of health care. Previous efforts (regulation, competition, voluntary action) have included almost every strategy except clinical. Insurers have largely failed in their cost-containment efforts. There is a strong emerging body of literature that demonstrates the relationship…

When children first hear the term "sound wave" perhaps they might associate it with the way a hand waves or perhaps the squiggly line image on a television monitor when sound recordings are being made. Research suggests that children tend to think sound somehow travels as a discrete package, a fast-moving invisible thing, and not something that…

This article is a response to a study "Gifted or ADHD? The Possibilities of Misdiagnosis," by D. Niall Hartnett, Jason Nelson, and Anne Rinn. A critique of the authors' claim about misdiagnosis of gifted children with ADHD, as well as their experiment and conclusions, is presented. The paper disputes an idea, prevalent in the gifted education…

Analogy in science knew its successes and failures, as illustrated by examples from the eighteenth-century physics. At times, some scientists abstained from using a certain analogy on the ground that it had not yet been demonstrated. Several false discoveries in the 18th and early 19th centuries appeared to support their caution. It is now clear…

Much contemporary library thinking and planning hinges on the belief that the true telos (or mission) of libraries is to merge into the new electronic environment, usually referred to metonymically as "the Internet." In this article, I argue that those who propagate the Internet as the coming information paradise, subsuming and superseding…

Although university-level distance education often sets itself up in contradistinction to conventional educational provision, the thinking most distance educators is framed by a set of un-stated axioms that derive from the conventional system. This axiomatically framed approach to university education at a distance may well blunt the potential for…
