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)

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)

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)

Manipulatives make possible an indispensable form of hands-on investigation in science instruction. A Yale University study found that simple objects kept elementary-age children involved and entertained with very high levels of attention and concentration. Manipulatives also encourage social interaction, enhancing cooperation, harmony,…

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)

Enables students to examine the time course for seed imbibition and the pressure generated by imbibing seeds. Provides background information, detailed procedures, and ideas for further investigation. (DDR)

Describes the use of an inexpensive device consisting of a plastic soda bottle and a modified plastic cap in a range of demonstrations and experimental activities having to do with the behavior of gases. (Author/WRM)

Evaluates a thematic program designed for use in introductory biology courses. Main objectives include the following: to provide relevancy of biological concepts beyond the classroom, be process oriented, integrate units within a biology course, teach for higher-order thinking, and expand the use of resources beyond the textbook. (CCM)

Discusses the advantages and disadvantages of using laptop computers rather than desktop computers in science classroom and laboratory instruction. Finds that while laptops provide greater flexibility, they come at a greater expense. Lists the uses of laptops in a departmental curriculum. (Author/WRM)

Describes a freshman biology laboratory project that uses the polymerase chain reaction to introduce students to the interrelationship between biology and chemistry. Students must develop their own experimental protocol, perform calculations introduced in freshman classes, and evaluate group dynamics. (Author/WRM)

Describes a Physics Exploration Center, a space where students solve lecture-related homework problems in a hands-on facility. (CCM)
