Discusses the use of analogies and other instructional strategies (problem solving, demonstration, group labs, and large group discussion) in dealing with students' preconceptions in physics. (PR)

Describes the use of analogy relative to the classical theory of momentum and kinetic energy, and addresses the advantages and disadvantages of this approach with respect to modern physics. Discusses the origins of the billiard ball analogy in the work of Coriolis and its influence on later theories and investigations of nuclear fission, particle…

Resources that are available for teachers presenting astronomy in the National Curriculum are listed. Included are societies and organizations, resource centers and places to visit, planetaria, telescopes and binoculars, planispheres, star charts, night sky diaries, equipment, audiovisual materials, computer software, books, and magazines. (KR)

Described is the V-scope which is a Micro-Based Laboratory system that provides direct and immediate displays of real motion as spatial images (stroboscopic snapshots), as time graphs of any combination of position, velocity, and acceleration, or as vector diagrams of velocity and acceleration. Illustrations of system components and of typical…

Discussed is the possibility that the salmon found in the Columbia River (Idaho) is an endangered species. A list of threatened or endangered animal species in the Pacific Northwest is included. Activities that deal with the topics of diversity, endangered species, and what is being done about them are provided. (KR)

A remedial biology course that employed six planned strategies to guide program activity is described. Team planning and team teaching, mastery learning, process skill emphasis, technology emphasis, positive reinforcement grading, attendance incentives, student achievement, student attitudes, parent attitudes, and implications are topics of…

Presents the experience of a Canadian Science-Technology-Society (STS) curriculum project as an indication of the problems that likely follow from attempts to introduce a STS curriculum piecemeal. These problems include redundancy within school curriculum and reduced time for science concept and term acceptability of the STS proposals. (PR)

Describes two basic types of software for beginning geology classes: general programs used to illustrate geologic phenomena (for example superposition) and programs written for specifically for geologic applications. (PR)

Three years after end of 2-year intervention program intended to promote formal operational thinking, achievement of students initially age 11 was tested by their results on British National examinations, taken at age 16 (experimental group n=88, control group n=103). In comparison with control classes, the effect size for science was 0.67,…

Describes the use of the computer in the laboratory for data acquisition and analysis--specifically a method to measure the respiration rate in aquatic organisms. Demonstrates the use of computer-interfaced pH measurement in the introductory biology laboratory. (PR)

Investigation found that instruction through the use of the sociocultural mode has a positive effect on students' attitudes toward learning science (n=600 Nigerian students). The findings also indicate that anthropomorphic and mechanistic views can be presented in such a way as to promote positive attitudes toward the study of science in…

This study examined sex- and ethnic-related differences in technology use in secondary school science and mathematics classrooms. Female students reported that they were less likely to use computers than males but more likely to use calculators. African American students were found to use computers more than Hispanic and white students, whereas…

Describes a two-week lesson on electric fields that combined lecture, interactive video, lab experimentation, computer spread sheets, and computer-assisted-graphing. (PR)

Describes how the Hershey Montessori Farm School in Huntsburg, Ohio, developed an advanced biology course, which begins with an experience-based, task-oriented approach within different biomes of the surrounding environs while incorporating high school content and scientific method. Concludes that integrating place-based and contextual inquiries…

This study examined hands-on experiences in the context of an investigation of viruses and explored how and why hands-on experiences may be effective. We sought to understand whether or not touching and manipulating materials and objects could lead to a deeper, more effective type of knowing than that we obtain from sight or sound alone. Four…
