The building of models to explain data and make predictions constitutes an important goal in molecular biology research. To give students the opportunity to practice such model building, two digital cases had previously been developed in which students are guided to build a model step by step. In this article, the development and initial…

What better way to clarify a topic and allow it to come alive than to provide students with a way to actually see it? Images, diagrams, and flowcharts can draw students in. In this article, the author reviews "Roche Genetics: Education Program" CD-ROM version 4.0. The program is organized using a theme park analogy. An information booth leads to a…

Most biology teachers implement animal dissection (real or virtual) and often lead discussions on research involving animal subjects. Such activities provide excellent opportunities to explore ideas about ethical conduct in the care and use of animals. The challenge for teachers is to present information about animal care and use that enables…

Discusses two of the major research trends that are broadening the understanding of fluvial processes and changing the approach to investigations of stream behavior. These trends include research on rivers that do not flow in alluvial channels and detailed field studies on the mechanics of fluvial processes. (JN)

Discusses development of a research program in the chemistry department at Sir Wilfred Grenfell College, a regional campus of Memorial University of Newfoundland. Considers both chemical and chemical education research programs and difficulties encountered in their development. Indicates advantages in conducting educational rather than scientific…

Reviews creationist arguments attacking scientific evidence for evolution and an old earth, presenting counter-arguments from the evolutionist's point of view. (CS)

Outlines general principles in observing sharp electron spin resonance (ESR) lines in the solid state by incorporating the transition metal ion of interest into an isostructural diamagnetic host material in small concentration. Examples of some recent studies are described. (CS)

Considers a few areas of oxide/sulfide and intercalation-type chemistry. Discusses synthesis of the disulfides of the metals of group IVB, VB, and VIB; the intercalation reaction between lithium and titanium disulfide; other intercalates; and sulfide catalysts. (CS)

Interviews were conducted with Year 6 students (n=67) and Year 10 students (n=58) who were asked whether scientists can do anything about endangered species. Most students gave positive answers which were at variance with the stereotyped image of scientists. It was concluded that students have private perceptions of scientists and their work as…

Describes a series of exercises intended to help students develop a better understanding of chromatography that employ plant pigments. A collaborative approach leads students to a level of competence that permits them to complete an open-ended exercise. (WRM)

Scientific inquiry provides the framework for the content and strategies recommended in the National Science Education Standards (NRC 2000). It's a hot topic at workshops and conferences, and many feel a bit guilty that they aren't doing more of it. Why is scientific inquiry currently at the forefront of science education reform? Inquiry works!…

The aim of this study was to develop a new research-based learning unit for tides to be used in lower secondary schools. The learning unit was based on the scientific theory of tides, textbooks, and also an analysis of students' conceptions. Descriptions are included of the content and the teaching-learning activities of the unit. The teacher talk…

The practice of science has been characterized as the systematic application of common sense. This view, frequently held by scientists themselves, holds that the same qualities that allow pre-industrial societies, pioneers, cast-aways, and common folk everywhere to cope with their environment and prosper also make for good scientists. However,…

Eighty years after the famous 1925 Scopes "monkey trial," which tested a teacher's right to discuss the theory of evolution in the classroom, evolution--and its most recent counterview, called "intelligent design"--are in the headlines again, and just about everyone seems to have an opinion. This past July, President Bush weighed in, telling…

Chemistry Is in the News (CIITN) is an innovative project aimed at enhancing higher-order cognitive skills (HOCS) via connecting university-level chemistry to everyday life and real-world issues. The CIITN project and its related Web tools were presented in a workshop to illustrate their conceptual framework, educational potential, and…
