Describes an audiotutorial program in Biological Science offered to non-science majors at Western Michigan University and reports the results of an evaluative investigation relating to this program. (JR)

Reports the effects of exposing both kindergarten and elementary school children to high and low speed motion pictures on children's estimation of time. Concluded the children's judgment is dependent upon their chronological ages and daily experiences of visual perception. (CC)

Discusses the use of a set of experiments to provide undergraduate electrical engineering students with a knowledge of the state of the art in modern coherent optics from an engineering standpoint. (CC)

Describes a program in applied biology in which the simulation of the production of penicillin in a batch fermentor is used as a teaching technique to give students experience before handling a genuine industrial fermentation process. Details are given for the calculation of minimum production cost. (JR)

Describes the conduct of a new course in Peru designed for physics teachers at the university level with emphases upon learning of up-to-date teaching and laboratory techniques. Included is a description of local degree programs and basic philosophy underlying teacher education. (CC)

Discusses the procedures of conducting skill sessions in the teaching of physics to undergraduates. Indicates that the interim method can help students in acquiring necessary skills to solve problems but needs further improvement to become more useful. (CC)

The comparative effectiveness of an aversive stimulus, withholding of resources, withdrawal of love, and reasoning, when used alone and when combined with praise, was assessed in a standard laboratory punishment paradigm with first and second grade children. (CS)

Discusses the design of a modified loop-the-loop apparatus in which a water stream is used to illustrate centripetal forces and phenomena of high-velocity hydrodynamics. Included are some procedures of carrying out lecture demonstrations. (CC)
