A technique for the numerical identification of bacteria using normalized likelihoods calculated from a probabilistic database is described, and the principles of the technique are explained. The listing of the computer program is included. Specimen results from the program, and examples of how they should be interpreted, are given. (KR)

Described is a summer workshop for college and high school educators designed to raise the level of expertise of the participants and to raise their awareness of physiology and medical opportunities for their students. The objectives, organization, schedule, content, credit, financial considerations, and evaluation of the program are discussed.…

Research concerning the role of stratospheric ozone and the effect of chlorofluorocarbons on stratospheric ozone are discussed. The consequences of global ozone depletion are projected. The Montreal Protocol is reviewed. (CW)

Investigated is the extent to which students' nonscientific beliefs change by comparing before and after instruction as a function of students' reasoning skill. Nonscientific beliefs discussed include special creation, orthogenesis, the soul, nonreductionism, vitalism, teleology, and nonemergentism. (KR)

Described is an interdisciplinary unit on pseudoscience which combines interest in unidentified flying objects (UFO's), physics, astronomy, art, and english composition. The different phases of the lesson, assignments, and evaluation are discussed. A list of books available on UFOs is provided. (CW)

A simple experimental arrangement that makes it possible to simultaneously observe and compare on a screen the two interference patterns produced by reflected and transmitted light from incident white light impinging on a soap film directly is described. Procedures and illustrated effects are discussed. (CW)

Two experiments which can be used to illustrate light diffraction using compact disks are detailed. Included are procedures, computations, and probable results. (CW)

Ten demonstrations of a variety of physics concepts are presented. Included are procedures and explanations of the effects illustrated. (CW)

The implementation and results of the use of videotapes in introductory biochemical engineering classes are discussed. The topics of the videotapes and the results of a questionnaire about this instructional method are presented. (CW)

Announced is an approval service for associate degree programs in chemical technology at two-year colleges. Features of the program and ways that institutions may become involved in the program are discussed. (CW)

Describes using the course question: "How does chemistry (or biology) impact my personal life and society?" This course question is presented to students and forms the basis of the final exam. Students evaluate a current-events article using the question as a framework. Students explore the relationship between chemistry (or biology) and their…

Describes the use of practice weighings and handling of fluorescent compounds to assist in teaching students safe-handling techniques. (PR)

Many students are deterred from science because of the way science courses are packaged. To find out what makes science hard for intelligent students, the author employed nonscience faculty and graduate students as surrogate students in science. Their responses to the sequence of the units, demonstrations, homework assignments, examinations, and…

Presents an interdisciplinary approach to introductory biology using a learning community model that addresses many of the American Association for the Advancement of Science's (AAAS) and Sigma Xi's objectives in the teaching of introductory science courses. (PR)

Explores how changing curriculum and teaching techniques may lead to different composition of pool of scientists who hold slightly modified theoretical perspective. Presents seven-stage spiral model for transforming mathematics and science teaching, in which each stage fuels change in next stage, moving toward more accessible, varied, and humane…
