An interactive computer program in microbial genetics is described. The simulation allows students to work at their own pace and develop understanding of microbial techniques as they choose donor bacterial strains, specify selective media, and interact with demonstration experiments. Sample questions and outputs are included. (DH)

Rough economic and political readjustments which academic science face are discussed at a special meeting of the National Academy of Sciences. Ill-equipped laboratories, new federal regulations over waste disposal and animal care, and lack of funds have contributed to the problem of rebuilding and renovating academic laboratories. (DH)

Describes a microcomputer program (written for the Apple II+) which can serve as a lecture demonstration aid in explaining genetic transcription and translation. The program provides unemotional information on student errors, thus serving as a review drill to supplement the classroom. Student participation and instructor options are discussed. (DH)

Background information and procedures are provided for an experiment (suitable for both advanced high school and undergraduate students) which: (1) illustrates the concept of a catalytic oxidation cycle; and (2) demonstrates the technique of using a gaseous reagent. Other uses of the experiment are noted. (JN)

Provides background information for teachers on the mathematical and biological theories of death and aging, focusing primarily on higher animals and humans. Areas of the curriculum into which such topics could be introduced are outlined. (JN)

Offers examples of activities and practical ideas for the instruction of process skills in a laboratory setting. Includes suggestions for the processes of observing, comparing, inferring, collecting data, organizing data, interpreting results, identifying variables, formulating hypotheses, experimenting, predicting, and model building. (ML)

Offers a series of experiments which introduce students to the general principles of enzymology. The experiment demonstrates several basic enzyme properties and the chromatographic exercises provide an analysis of each enzymatic activity. Questions are also presented for extending discussion on the activities. (ML)

Annotates reference material on artificial intelligence, mostly at an introductory level, with applications to education and learning. Topics include: (1) programing languages; (2) expert systems; (3) language instruction; (4) tutoring systems; and (5) problem solving and reasoning. (JM)

Describes development and content of a speech science course taught to speech therapists for two years, modified by feedback from those two classes. Presents basic topics and concepts covered. Evaluates a team teaching approach as well as the efficacy of teaching physics relevant to vocational interests. (JM)

Describes a solid etalon Fabry-Perot interferometer, discussing free spectral range, instrumental finesse, and temperature effects. Provides schematic of temperature control/display circuit. Explains use of 100 millimeter camera lens and 10 power micrometer eyepiece for resolving rings and measure diameters. (JM)

Describes a computer simulation program which helps students learn the main biochemical tests and profiles for identifying medically important bacteria. Also discusses the advantages and applications of this type of approach. (ML)

Offers perspectives on natural selection and the phenomenon of altruism. Presents evidence for and against the theories that evolution acts essentially on genes, on individuals, on kin, or on larger groups. (ML)

Shows how a simple diagram of instructional concepts (concept map) can help the teacher to organize class material and reduce the likelihood of rote memorization. The example provided is used for sequencing of instruction for a unit on the nervous system. (JN)

Addresses these three questions: (1) What are the roles of analytical chemists in industry? (2) What training is needed to fill assignments which make up these roles? and (3) What are some of the major challenges facing analytical chemists during the next five years? Includes information about a workshop for students. (JN)

Describes (1) computer graphics for the coefficient of restitution; (2) an experiment on the optical processing of images; and (3) a simple, coherent optical system for character recognition using Polaroid (Type 665) negative film. (JN)
