Contends that the large vocabulary used for precise purposes in physics contains many words that have related but potentially confusing meanings in everyday usage. Analyzes the treatment of Newton's Laws of Motion in several well-known introductory textbooks for evidence of inconsistent language use. Makes teaching suggestions. (Contains 11…

Addresses the apparent conflicts between the ideas of evolutionary biology and the Jewish faith, especially those related to literal interpretations of the Old Testament. Believes that lurking behind the would-be debate between the Torah and evolution is either a shallow understanding of the Torah, or an unsophisticated appreciation of science, or…

Describes a physical system for demonstrating operators, eigenvalues, and superposition of states for a set of unusual wave functions. Uses candy to provide students with a visual and concrete picture of a superposition of states rather than an abstract plot of several overlaid mathematical states. (WRM)

Measurement of the compositions and temperatures of H2O-NaCl brines in equilibrium with ice can be used as an easy in-class experimental determination of a liquidus. This experiment emphasizes the symmetry of the behavior of brines with regard to the minerals ice and halite and helps to free students from the conceptual tethers of one-component…

Describes the Science Concept-Vocabulary Acquisition (SCVA) model which promotes simultaneous cognitive construction of science concepts and the scientific nomenclature needed to understand and communicate those concepts. Contains 19 references. (DDR)

Integrates findings from qualitative and quantitative research in conceptual change that investigated text and text-based strategies. Emphasizes findings that have direct implications for instructional research and practice: (1) refutational text is not sufficient to produce conceptual change; (2) discussion of refutational text must be…

Examines reader and text variables related to conceptual change learning from science textbooks. Shows it is difficult to change readers' prior knowledge by reading texts that are inconsistent with that knowledge, but refutation text was shown to impact students' prior knowledge when that knowledge contained naive scientific conceptions. Addresses…

Examines conceptual change research to develop an instructional framework for science educators consonant with research on special education populations. Delineates a taxonomy of knowledge structures (classification, structure, process/mechanism, and concept/theory frames) derived from research that may be used to guide teaching strategy…

Asks if literature can open up and revitalize the scientific study of astronomy in elementary classrooms. Reviews the author's personal thinking and exploration that led to bringing science and literature together in powerful ways. Discusses how scientific principles can be embedded in a rich foundation of literature and student inquiry. (SG)

Describes an experiment in which groups of students in a plant tissue culture course worked together to test application of the Skoog-Miller model (developed by Skoog and Miller in regeneration of tobacco experiments to demonstrate organogenesis) to sweet potato root explants. (ZWH)

Describes a science experiment that gives students experiences with the float-sink phenomena and allows them to practice what Piaget called formal operational thinking. The goal of the experiment is to determine some of the variables responsible for cans of soda sinking or floating. (TJQ)

Describes two activities to analyze unit-cell structures from a geometric viewpoint and invites students to apply their mathematical understanding to scientific phenomena. Students form models of the simple cube, a building block of crystalline structures, and a methane molecule. (MKR)

Low-achieving seventh-grade students were assigned to two science intervention groups, a read-and-discuss teacher-directed method group and a group in which a model of concept mapping that connected major and minor concepts followed the lesson. Results indicate that using graphic representations was more effective than the traditional approach.…

The British National Curriculum calls for children to work with living things. Discusses alternatives available for teaching children about bugs, most notably through models and live animals kept in school. Models prove valuable for introducing children to bugs and for stimulating them to ask scientific questions. Raises issues behind keeping live…

Examines the design and construction of a mini-sextant and its use in demonstrating Fresnel reflection, geometric optics, and several common optical techniques. A sidebar explains the basic use of the mini-sextant as a navigational tool. (WRM)
