Background information, procedures, and typical results are provided for a three-part experiment involving reactions of potassium thiocynate (KNCS) with sulfuric acid. The experiment represents the final stage of structured work prior to students' research projects during their final year. (JM)

Examines issues related to career choice and career counseling in the biological sciences, stressing self-inventory, development of supporting area, experience in research, flexibility, use of the counseling resources, and active involvement in the career decision process. Provides results of a study profiling alumni career data. (JM)

Describes 70 computer programs related to (1) structural geology; (2) sedimentology and stratigraphy; and (3) the environment, groundwater, glacial geology, and oceanography. Potential use(s), language, required hardware, and sources are included. (JM)

Discusses issues related to the missions of national laboratories as well as to the quality of their staffs. Indicates that although dilemmas exist within these institutions, an examination of such issues as management problems and institutional goals and activities may lead to an improvement of these national resources. (JN)

Describes information-processing research, showing how computer models are used to explain thinking and how information processing approaches can be used systematically. Clarifies why students find factor-label method so difficult to master and discusses guidelines and suggestions for using information-processing ideas. (JM)

The usual apparatus for demonstrating Boyle's law produces reasonably accurate results, but is not impressive as a demonstration because students cannot easily appreciate the change in pressure. An apparatus designed to produce a more effective demonstration is described. Procedures employed are also described. (JN)

A group of 33 individuals toured the People's Republic of China and the Soviet Union under auspices of People-to-People International. Physics education in and general impressions of these two countries as well as problems and values associated with this kind of travel program are discussed. (JN)

A Michigan State University committee examined major problems and issues confronting precollege science educators at national and state levels. A summary of these problems and issues is presented, along with specific recommendations for action in the state of Michigan. (JN)

Alternatives to traditional, large-class lecturing are discussed. They include using canned lectures, demonstrations and lecture experiments, computer simulations, problem-solving strategies, breaks during lectures, and movies. Moving out of large classrooms to laboratories and resource rooms (or giving an examination) is also suggested. (JN)

Describes a versatile electric circuit, a simple and inexpensive vibration generator, and digital electronics demonstrations (with light bulbs) using a microcomputer. Also discusses bimetallic strips and their use as thermostats and the electrical resistance and resistivity of metals. (JN)

Describes eight steps in producing computer-assisted-instruction materials. They include selecting a topic, selecting approach to the topic, researching the topic, obtaining a programmer, writing problem definition, soliciting evaluation, field testing, preparing documentation, and monitoring efforts during program production. Also describes a…

Examines the need for a science of toxicology and training at both the undergraduate and graduate levels in response to legislation controlling drugs, food additives and toxic substances in the work environment, and concern about effects on man. Stresses need for putting toxicology on a scientific base with adequate funding. (JM)

Describes "Experiments in Chemistry," in which experiments are performed using software and hardware interfaced to the Apple microcomputer's game paddle port. Experiments include temperature, pH electrode, and EMF (cell potential determinations, oxidation-reduction titrations, and precipitation titrations) investigations. (JN)

Indicates that present curricula are not preparing citizens to deal with critical social issues, in particular, those related to the environment, energy, food supply, and population problems. Offers 10 suggestions to help remedy the situation. (JN)

Describes a computerized method to test error analysis that helps motivate introductory physics students to learn the topic. The computer generates a test consisting of four topics from a list of 10 that students should know. Numerical data within realistic ranges are also generated. (JN)
