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)

Reviewed is some of the experimental evidence for apostatic selection from work with artificial prey. Guidelines for further experiments are suggested including experimental design, analysis, variables, and selection in the wild. (Author/CW)

Provides a set of guidelines for infection control of the Acquired Immune Deficiency Syndrome and the serum hepatitis viruses during blood typing procedures. Emphasizes that disposal of blood contaminated materials should comply with local health department recommendations. (RT)

Presents a method which introduces biology students to some fundamental aspects of scientific methodology. Explains simple muscle testing procedures, a historical perspective, experimental variables, pedagogical uses, and possible mechanisms of the muscle response phenomenon action. (RT)

Explains the surge in publishing activity of science, the development of a standardized technical vocabulary, and the adoption of modern equipment for the transmission of information. Discusses the pioneer in scientific journalism, scientific writing, and the progress of Arab scientific journalism. (RT)

Discussed is single crystal X-ray crystal structure analysis. A common link between the NMR imaging and the traditional X-ray crystal structure analysis is reported. Claims that comparisons aid in the understanding of both techniques. (MVL)

Presents survey results from freshman engineering students at Colorado State University. Identifies the highest levels of math and computer courses taken. Notes although most students took high school calculus, 48 percent failed the college's analytical trigonometry examination. Develops practical ideas for the future. (MVL)
