Applies the narrow-band model to the instruction of intrinsic and extrinsic semiconductors along with the phenomenon of compensation. Advocates the model for undergraduate instruction due to its intuitive appeal and mathematical simplicity. (CP)

Describes a number of undergraduate laboratory experiments that illustrate the science of alchemy as it was historically practiced. (MLH)

Presents several demonstrations in spectroscopy. (RH)

Presents the results of a questionnaire sent by the American Chemical Society (ACS) to university chemistry departments concerning their use of student questionnaires in evaluating instructors and courses. (MLH)

Describes a dry-lab experiment in which the student is provided with a set of fluorescence spectra of quinine for study and interpretation. (MLH)

Describes undergraduate experiments concerning three topics: oxygen carriers, nitrogen fixation, and metal activated enzymes. (MLH)

This article provides information to aid in starting a course in musical acoustics. The selection of topics for lecture, a project-mode laboratory, texts, references, equipment, and lecture demonstrations are covered. (Author/CP)

Describes a simple microwave interferometer capable of measuring small phase shifts. Proposes laboratory exercises involving the use of the interferometer in the determination of refractive indices of gases and the analysis of the reflection in a test chamber. (Author/CP)

Discusses the complex emotional and social problems facing the youth in college. Proposes that educators convey to the students the value of learning and how it contributes to personal growth. (MLH)

Describes a college-level chemistry laboratory format in which students individually schedule their laboratory time and use a slide-tape medium in place of a laboratory lecture. (MLH)

Presents three activities: (1) the investigation of the purity and stability of nicotinamide and flavin coenzymes; (2) desk-computer fitting of a two-exponential function; and (3) an interesting and inexpensive solubility product experiment for introductory chemistry. (RH)

Presents a ten-item multiple choice quiz and the correlations between grades on this quiz and grades in an undergraduate physical chemistry course at Purdue University. (MLH)

Describes a teaching model that consists of a plywood box containing mechanisms that instruct the student about the technical aspects of an infrared spectrophotometer and how a spectrum is generated. (MLH)

Describes an experiment in which a racemic mixture of a coordination compound is resolved. (MLH)
