This publication, published quarterly by the American Institute of Biological Sciences, focuses on biology education in colleges and universities. Included in this issue are articles dealing with mini-investigative labs in microbiology for nonscience students, the effects of various components of the Keller system on student attitudes and…

This article was designed to help teachers with ideas for classroom learning centers. Suggestions for making puppets were provided and students were given the opportunity to use their imagination and think creatively. (Editor/RK)

Seven-slide series produced by the Diafilm Studio are discussed as they are used as demonstration material for teaching students detailed familiarity with the morphology of the plants in given families and with the variety of their representatives. (Author/ND)

Serving as an educational resource center for Connecticut public schools and institutions of higher learning, Project Oceanology provides 256 programs in marine education via a "floating laboratory", a waterfront laboratory, and a classroom equipped for individual study. (JC)

The design and use of various types of mathematics learning centers are discussed; suggestions for evaluation of centers are offered. A sample learning center, designed to teach first graders linear measurement, is described in detail. (SD)

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

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)

Topics discussed are: what the city is, what a good urban school is not, and criteria of good urban schools. Approaches that maximize and utilize the city as a center for learning are given through an examination of five models of urban schools. (Author/AM)

Variations on familiar games which can be used to motivate mathematics learning are described. (SD)

Several activities in which students use geometric shapes and their shadows to study geometric concepts are described. (SD)

Lists some reasons why the vast resource potential of entomology remains largely untapped by teachers of general biology. (LS)
