Science-prone students are both academically gifted and display a driving interest in science. Describes the origins and evolution of the Science Talent Search Program, a program designed to identify science-prone high school students. Discusses variations of four exemplars of the program. (Contains 46 references.) (MDH)

Survey results contrast teachers' (n=159) knowledge and understanding with the understanding levels expected by England's science National Curriculum. Teacher's understanding with respect to the concepts of force, energy, and changes in materials are discussed. (Contains 29 references.) (MDH)

Children in grade one (n=8) and grade five (n=9) were interviewed to determine the influence of contexts of meaning on their knowledge of earthworms. Four components of contexts of meaning were identified and discussed: episodic knowledge, metaphors, interpretive frameworks, and emotions-values-aesthetics. (Contains 20 references.) (MDH)

Discusses (1) the need for teachers to understand student conceptions; (2) alternative conceptions that students formulate; (3) changing conceptions; (4) representing conceptual knowledge for studying conceptual change; (5) strategies for inducing change; and (6) a taxonomy of conceptual change. (Contains 61 references.) (MDH)

Describes a unit of hands-on activities on the corrosion of iron and steel. The unit uses the learning cycle and the science/technology/society approach. Three activities are presented. (PR)

Describes the "Physics by Inquiry" course that is designed to address student misconceptions. Explains how the course was taught at the University of North Carolina at Greensboro for teachers and how it was taught at Ohio State University for elementary-education majors. Concludes the course is exportable to many different environments…

Discusses the current and future roles of two-year colleges in science, mathematics, and engineering education. (PR)

Compared the effects of participation in six extra credit activities for teaching the concept of matter on female preservice elementary school teachers (n=9) to a control group (n=8). Pre- and posttests to assess changes in the students' understanding of phenomena associated with matter indicated significant changes in experimental students'…

Students discover science resources in their neighborhood that help them see the relevance and long-term applications of concepts learned in the classroom. Students explore people, objects, and geographic resources beginning in the school and extending out into the community. (MDH)

Describes bioluminescence and the chemistry of how it occurs. Presents information for conducting the following classroom activities: (1) firefly mimic; (2) modeling deep-sea fish; (3) sea fireflies; and (4) the chemistry of light. (PR)

Describes inexpensive and safe activities centered around the chemistry of effervescent products such as Alka-Seltzer. Activities demonstrate the following: water-induced reactions, the influence of humidity, temperature and rate of reaction, particle size and rate of reaction, concentration and rate of reaction, the neutralizing power of…

Discusses the following questions in choosing distance education courses: Will I be able to "talk" with the instructor? Will I be able to talk with other course participants? Does the course include laboratories or other hands-on experiences? What equipment will I need to participate? What technical assistance will be available? Who is the course…

Rebuts the case made by Donald Williams in "Making a Case for the Science Specialist." Argues that using science specialists gives the impression that science is only for certain people. Considers points made by preservice teachers in Williams' article concerning attitude, curricular concerns, and teaching science using real-life…

Discusses a child-centered science project in which first-grade students integrate design drawing, construction, mathematics, and language arts to solve engineering problems related to constructing robots. Describes the construction of the robots, follow-up activities, and educational research that supports this approach to teaching. (10…

Conceptual change teaching is an instructional method that helps students modify, extend, or exchange their alternative conceptions for the appropriate scientific conceptions. Provides activities and a diagnostic test to apply the method to the concepts of heat and temperature. (MDH)
