A content-specific staff development summer institute upgraded teachers' knowledge of chemistry concepts, increased familiarity with pedagogical strategies, and facilitated transfer of program initiatives into the classroom. A 2.5-year study indicated that the program was beneficial. Three essential program components were modeling and practicing…

Describes the use of thought-provoking essay questions such as "How does one determine the temperature at which Hell freezes over?" to promote better communication skills among chemistry students. Makes reference to and suggests other thought-provoking questions. (WRM)

Describes gender differences in the use of online chat room tutorials by nontraditional chemistry students enrolled in distance-learning sections of a general chemistry course. (Author/CCM)

Reports on a community-service project carried out by general chemistry students at the University of Utah. Students research lead poisoning then visit neighborhood homes to teach about lead poisoning, collect exterior paint samples, and analyze them as part of a chemistry experiment. Discusses service-learning and laboratory activities. (WRM)

Correlates the kinds of strategies associated with a deep approach to learning science. Analyzes the interactions of two groups of grade 8 students while they were engaged in hands-on science activities during instruction in a chemistry unit. Focuses on two students who showed a deep approach to learning. (Contains 47 references.) (Author/YDS)

This case study narrative of a middle school science teacher's experience of science education and commitment to promoting equity was developed collaboratively by the teacher and a university researcher. It demonstrates how this form of case study can be a way to represent teachers' practical knowledge. (SK)

Presents a test of the limits of the Johnstone--El-Banna model of problem solving as related to students' responses to organic-synthesis problems. Finds that the predicted pattern was observed in both samples, although the model was more useful for students without previous problem-solving training and for field-independent and field-intermediate…

Makes recommendations for new science teachers about what to do in the middle level classroom. Advocates being creative in the classroom and in finding resources. (YDS)

Describes a series of simple but spectacular chemistry demonstrations designed to capture children's imaginations. The demonstrations take the minimum amount of time to prepare, are relatively safe to dispose of, and reliable. (Author/WRM)

Describes a laboratory exercise for undergraduate science students in which they evaluate soil samples for various parameters related to suitability for crop production and capability for retention of contaminants. (Contains 18 references.) (WRM)

Presents an activity that allows students to remove tarnish from silver using the reaction of tarnish with aluminum rather than the abrasion method of commercial tarnish removers. Makes suggestions for adapting the activity to an at-home investigation. (WRM)

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)

Describes a set of simple, inexpensive, classical demonstrations of nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) principles that illustrate the resonance condition associated with magnetic dipoles and the dependence of the resonance frequency on environment. (WRM)

Investigated the ability of Swedish student teachers to explain everyday phenomena in science education, asking all fourth-term student teachers about phenomena where transformations of matter were involved. Analysis of students' written answers indicates that there is a great need in teacher training to work with conceptual understanding and with…

Details a project in which students explore and study the poisons in their environment by asking and finding answers to their own research questions. Includes some suggestions for involving students successfully in inquiry-based learning. (DDR)
