Describes exercises using simple ball and stick models which students with no chemistry background can solve in the context of the original discovery. Examples include the tartaric acid and benzene problems. (GS)

Describes an experiment designed to augment textual materials conducive to the inquiry approach to learning. The experiment is the culminating experience in a series designed to illustrate the fundamental nature of the atom: its quantized energy nature, its electrical nature, and its combining ability. (Author/GS)

Reflects on the declining enrollment of students in first year chemistry courses. Suggests causes for this decline which include disenchantment with science, capricious chemical industry recruitment, exaggerated employment difficulties, and teaching approaches at both the secondary and tertiary levels. (GS)

This investigation involved a sample of 857 students drawn from college freshmen taking beginning biology during one quarter at Iowa State University. Students were selected on the basis of five factors. The Minnesota Scholastic Aptitutde Test (MSAT) and the Mathematics Placement Test (MATH) raw scores were used as covariants; final grade in the…

Presents abstracts of the plenary lectures and contributed papers of a conference that covered the following areas: laboratory organization, integrated laboratory, instructional aids and equipment, computers, and general chemistry laboratory. (GS)

States that professional undergraduate education is enhanced by professors engaged in research because of the teacher's currency of knowledge, motivation, recognition of service, and involvement in unresolved problems. Indicates that the use of sponsored research takes the financial burden from the academic budget and permits employment of the…

Describes an experiment for recording holograms using a minimum of costly apparatus. Includes a description of apparatus and materials, the procedure for recording the hologram, the processing of the hologram, and the reconstruction of the image. (GS)

Describes modules designed to enable a student to learn a measurement technique and familiarize himself with measurement instrumentation independently of a laboratory course. Presents an example of a module involving the measurement of electrical resistance and lists other modules that have been developed. (GS)

Describes self-paced freshmen courses in electronics using study guides with questions answerable entirely from laboratory measurements. Discusses the problem of supplying students with needed results of evaluation quickly. No statistics are included. (GH)

Describes a combined demonstration and student experiment course to illustrate fundamental techniques, instrumentation, and concise report writing. Describes experiments including tensile tests, heat treatment, equilibrium diagram, microexamination, strain measurement, and recrystallization. (GH)

Describes an undergraduate experiment. Discusses a model for the behavior of bubbles under differing viscosities and pressure gradients and conditions for failure of the model. (GH)

Describes a course, without laboratory, using rudimentary algebra and covering such topics as gravitation, orbital mechanics, atomic structure, geomagnetism, electromagnetic spectrum, theory of relativity, extraterrestrial life, and interstellar travel. (GH)
