Identifies the misunderstandings and problem-solving strategies of secondary students when solving stoichiometry problems. (Author/CCM)

Students react similarly to a wide variety of conceptually unrelated situations. Describes a rule that is manifested when two systems are equal with respect to certain quantity A, but differ in another quantity B. Indicates that in such situations students often argue that the same amount of A implies the same amount of B. (Contains 30…

Finds that many restoration projects have attempted to replace the native species, but project planners often have an imperfect understanding of the plant communities they are trying to re-create. Argues that when students join these projects, they may receive an inaccurate impression of local ecosystems. (Author/CCM)

Attempts to allay the confusion between technology education and educational technology. Discusses their purpose and direction as well as the standards used in both areas.(JOW)

Examines how students completing a two-semester organic sequence understand, explain, and apply hydrogen bonding to determine the physical attributes of molecules. Suggests that some students completing what is typically their second year of college-level chemistry still possess misconceptions about hydrogen bonds. (Contains 21 references.) (ASK)

Examines children's understanding of burning focusing on questions such as: "What are children's views of burning prior to and after instruction?," and "Do children's views become more scientific?" A significant difference was found in children's understanding before and after instruction. (Author/MM)

Discusses the place of the topic of evolution in high school biology curricula in history, new challenges and misconceptions about science, and the need for biology education. (Contains 20 references.) (YDS)

This article reports on results of an exploratory study on undergraduate pre-service teachers' understanding of graphical representations of motion functions. The study described pre-service teachers' explorations using a CBR device. Pre-service teachers' growth was studied in two dimensions: (a) in their learning of the mathematics involved and…

Proper cooling of foods is known to reduce spoilage and help prevent food-borne illnesses. Nonetheless, little is known about consumers' awareness of guidelines regarding appropriate refrigeration of food or their actual refrigeration practices. Focus groups of consumers of common ethnic backgrounds were designed to evaluate food safety knowledge…

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.

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…
