Explains how Zebrina pendula can provide an excellent material for demonstrating a variety of cellular features in plants by using a dissecting microscope. (GA)

Compares two teaching forms of an introductory laboratory course in physics. Concludes that the individualized version is more efficient in learning time and, on the whole, more effective than the traditional version, even though the latter one seems to reinforce student's existing positive attitudes towards physics experimentation. (Author/GA)

Compares two grade 12 science classes, one receiving instruction using the Laboratory-Investigative Approach, and the other using the Lecture-Laboratory Approach, in terms of certain cognitive factors and associated attitudes. (GA)

An interdisciplinary laboratory course is described in which the experimental methodology of physics is applied to problems of potential research interest to the nonphysicist. Special attention is given to those practical considerations which determine the structure and content of such a course with particular emphasis on the unique pedagogical…

The use of participatory lecture demonstrations in the classroom is described. Examples are given for the following topics: chromatography, chemical kinetics, balancing equations, the gas laws, kinetic molecular theory, Henry's law of gas solubility, electronic energy levels in atoms, and translational, vibrational, and rotational energies of…

Arguments for microteaching as part of an introductory methods course are presented, and the role of the supervisor in setting up and conducting a microteaching laboratory is explored. (JMF)

Describes a laboratory demonstration to show how to determine the focal length of a thin glass lens under water. (GA)

Describes the results of a study on the use of computer-simulated chemistry experiments. Four different simulated experiments were compared with four comparable laboratory performed experiments. Concludes that simulation has better results and is a good teaching procedure. (GA)

The Japanese morning glory, a short-day plant, is an excellent specimen for studying photoperiodism. This article gives ideas for investigations including the effects of hormones, light quality, and temperature. Preparation of the seed is also discussed. (BB)

An open learning center designed to prepare students for the high school equivalency exam was developed, based on an analysis of the participation requirements of low-income adult learners. The setting, personnel, and mode of operation are discussed, and a flow chart of participant interaction is provided. (RAO)

Describes management procedures which have been developed to facilitate and coordinate staff efforts in a biology learning center at Ball State University, Muncie, Indiana. (HM)

Describes how to organize Learning Centers, the basic curriculum decisions to be made with respect to learning objectives, activities, materials involved, and the process of evaluation to monitor pupils' progress. (GA)

Describes a computer model kinetic theory experiment for the college physical chemistry laboratory. (HM)

Describes in detail the construction of an improved version of Hero's engine that is easy to operate and has a short response time. (GA)

Describes an exercise which familiarizes students with organic chemistry terms and introduces preferential degradation reactions. (CP)
