The impact and uses of new technologies in science teaching are discussed. Included are computers, software, sensors, integrated circuits, computer signal access, and computer interfaces. Uses and advantages of these new technologies are suggested. (CW)

Described is an approach that uses a computer spreadsheet program to calculate entropy change at constant temperature and pressure. The calculated values can be used in an associated graphing program. (CW)

The apparatus, reagents, preliminary classification, nomenclature, acquisition, and procedures used in the identification of synthetic polymers are described. Specific tests for the identification of the presence of hydrocarbons, chlorine, fluorine, sulfur, and nitrogen and the absence of halogens and sulfur are discussed. (CW)

The assembly and use of an Ostwald-type of viscometer from readily available materials is illustrated. Sample data and a schematic of the apparatus are provided. (CW)

Presented is a demonstration in which students are shown an objective view of the role of animals through the analysis of books about ecosystems. The book analysis method and lists of books about wetlands and terrestrial ecosystems are included. (CW)

Surveys of program graduates of a model science teacher education program were compared with responses from a national sample of exemplary teachers. Results indicated a high degree of similarity between the two groups and provided evidence that a good preservice science teacher education can have a positive effect on the development of preservice…

Describes three demonstrations showing chaotic motion, which makes long-term prediction impossible. Discusses the apparatus for the demonstrations and procedures for illustrating chaotic motion of pendulum, balls rolling in a double potential well, and a ball rolling on a balanced beam. (YP)

Summarizes the evaluation of computer software presented in "The Physics Teacher" since 1984. Describes several programs for integrating courseware use into classes including "TimeLog" for a message/bulletin board, Control Data "Physics 1" for problem solving, some demonstration programs, and "Physics Laboratory Programs" for programing skills.…

Outlines developments that took place in teaching agriculture at the freshman-sophomore level and the concept of integrated courses in agriculture. Future directions include: more emphasis on the impact of technology, case-study forms, and efforts to shift the balance from content to concept. (Author/RT)

Addresses four concerns faced by educators incorporating specific features of learning objectives into a course: structure of the course, students' acceptance of changes, time commitment required of professors, and format interference with presentation of subject-matter. (RT)

Reviews video programs and film materials for the teaching of mechanics. Describes 13 videos of the Open University. Discusses other resources of visual materials. (YP)

Investigates Italian high school and college students' awareness of the risks connected with both the civilian and military uses of nuclear energy. Summarizes some findings of this analysis and concludes that the education regarding nuclear issues does not meet current needs. Provides a questionnaire on nuclear issues. (YP)

Investigates a case study in the state of Qatar to find the interaction effect between an engineering laboratory and the community. Presents the results of two questionnaires for faculty members and engineers. Reports awareness and willingness to participate in a cooperative program, current lack of communication and inadequate laboratory…

Describes a course provided for health profession-oriented students. Uses a chemical basis to explain the physiology of drug action while considering appropriate patient care. Outlines course content and testing procedures. (Author)

Provides the methodology put forth by Moore and Kraus to separate Co++ from Ni++ in an 8M HCl solution. Notes that cobalt(II) forms a wide variety of anionic complexes. Points out that as the solutions leave the exchange column the color bands of green, blue, and pink are easily seen. (MVL)
