Aimed at improving officer education through the use of modern technology, a two-pronged computer-assisted instruction (CAI) effort was initiated. CAI techniques and methods utilized in the dual projects (CAI-Teletype and CAI 1500) are discussed under three categories: computational, non-computational, and computer management of instruction.…

This teacher's guide includes parts one and two of the four-part third year Portland Project, a three-year integrated secondary science curriculum sequence. The Harvard Project Physics textbook is used for reading assignments for part one. Assignments relate to waves, light, electricity, magnetic fields, Faraday and the electrical age,…

Describes two demonstrations to illustrate characteristics of substances. Outlines a method to detect the changes in pH levels during the electrolysis of water. Uses water pistols, one filled with methane gas and the other filled with water, to illustrate the differences in these two substances. (TW)

Encourages instruction about disposal of hazardous wastes in college chemistry laboratories as an integral part of experiments done by students. Discusses methods such as down-the-drain disposal, lab-pack disposal, precipitation and disposal, and precipitation and recovery. Suggests that faculty and students take more responsibility for waste…

Describes a six-week summer program for gifted high school students in mathematics, science, and computer programing, conducted by the Center for Mathematical Services at the University of South Florida. Discusses the assessment tests used and the courses and topics taught, particularly the chemistry concepts and skills. (TW)

Describes a generalist chemistry program being offered as a part of the liberal arts program at the University College of the Australian Defence Force Academy. Provides a rationale for developing the new generalist curriculum and contains syllabi from two chemistry courses in the program. (TW)

Discusses the potential of experiments as a vehicle and to motivate students to use text references to look up further information such as nomenclature, molecular geometry, properties and reactivities for various ions and molecules. Describes the procedures and discussion for three such experiments. (TW)

Argues that cookbook chemistry laboratory experiments do little to teach scientific inquiry. Suggests providing students with laboratory experiences that follow the introduction of a concept and challenge students to investigate that concept through an experiment involving very few initial instructions. Lists some such challenges used in chemistry…

Describes two laboratory demonstrations in chemistry. One uses dry ice, freon, and freezer bags to demonstrate volume changes, vapor-liquid equilibrium, a simulation of a rain forest, and vaporization. The other uses the clock reaction technique to illustrate fast reactions and kinetic problems in releasing carbon dioxide during respiration. (TW)

Reports on a study that examined the differential effectiveness of traditional and discovery methods of chemistry instruction in Zambia. Compared were the teaching of science concepts, understandings about science, and scientific attitudes to learners at the concrete and formal levels of cognitive development. (TW)

Reports on a study into the effectiveness of implementing an interactive videodisc science lesson on titration into a high school science program. Describes the titration lesson and the equipment used in two chemistry classes. Results were generated from achievement and attitude instruments, along with observational data. (TW)

Lists five experiments or demonstrations involving hypodermic syringes. The titles of experiments are Boyle's Law, Charles' Law, Atmospheric Pressure, Expansion of Gases, and Boiling at Reduced Pressure. Provides a list of materials, the typical data, and graphs where appropriate. (YP)

Explains ways three chemists use college courses, evening lectures, and television and radio programs to educate the public about the importance of chemistry. Indicates that exposure to the fundamentals of chemistry in the early grades may have a significant effect on changing the public's attitudes toward chemistry. (RT)

Describes the development of a topics course offered jointly by the chemistry and biology departments at Macalester College (Minnesota). Outlines the syllabus for the course. Discusses teaching and laboratory methods used. (CW)

Decribes a study which compared computer assisted instruction (CAI) with a parallel paper-and-pencil module to assess the impact on students' achievement and attitudes in chemistry. Supports the contention that CAI works as well or better than more traditional methods and tends to promote positive attitudes. (RT)
