Recommends the use of constructivist-based strategies to engage students who are not interested in science using traditional methods. Focuses on the application of these strategies in a laboratory experience exploring gas laws. (DDR)

Explains the use of a constructivist model for engaging students in the curriculum. The student end of the model is characterized by the knowledge, personal experience, degree of motivation, and level of interest that a student brings to a learning situation. (DDR)

Describes how teaching a lesson on the discovery of a crater in the Yucatan Peninsula and the rock strata deep in the ocean can help students explain the demise of dinosaurs. Discusses the impact theory and the core model. (DDR)

Explains the process of student and teacher collaboration on a project to develop a faster electrolysis mechanism. Provides a good example of the problem-based approach to science instruction and curriculum. (DDR)

Provides plans for simple, inexpensive teaching aids and equipment for visually impaired children. Details for building null detectors, electronic thermometers, and calorimeters are included. (DDR)

Examines the conceptual development of high school students' understanding of scientific research over a school year. Results indicate that students' notions of scientific questioning are uniformed and they have little experience with data analysis or communication of results. Contains 18 references. (DDR)

Enumerates concerns that educators have regarding the use of student data-collection tools such as the computer-based laboratory (CBL) and the microcomputer-based laboratory (MBL). Compares various types of data-collection technologies. (DDR)

Reports on a revision to the National Curriculum for Science in Great Britain that carries the danger of reverting to more prescriptive work with less emphasis on whole investigations. Uses a comparison between two exercises. (DDR)

Outlines an in-depth case study of teachers' use of image processing in biology, earth science, and physics classes in one high school science department. Explores issues surrounding technology implementation. Contains 21 references. (DDR)

Describes a summer program for teachers in the Hawaii Volcanoes National Park in which teachers share in hands-on activities that demonstrate volcanic processes including volcanic hazards, plate tectonics, and earthquakes. (DDR)

Outlines the experiences of a teacher in the National Oceanic and Atmospheric Administration's (NOAA) Teacher At Sea Program in which teachers are placed on NOAA vessels to work with professional scientists doing critical, real world research. (DDR)

Presents an account of one teacher's summer experiences on a vessel in the Bering Sea and the effects of those experiences on practice. Focuses on the teamwork among the science team, officers, and crew. (DDR)

Discusses the accomplishments of a model program characterized by an intense training program, an active network among teachers, and a learning-friendly laboratory classroom. (DDR)

Argues for the need for courses in waste management in departments other than civil engineering. Points out that although waste management is a business administration function, it is best performed from an environmental management perspective. (DDR)

Presents the self reports of Israeli junior high school teachers (N=40). Discusses the conditions and processes of teaching and learning science, and reports that teachers make good use of inquiry in teaching. Contains 20 references. (DDR)
