Researchers are often distressed to discover that the data they wanted to use in their landmark study is not configured in a way that is usable by a Statistical Analysis Software Package (SASP). For example, the data needed may come from two or more sources and it may not be clear to the researcher how to get them combined into one analyzable…

Reports on the comparative effectiveness of demonstration and lecture formats for presenting physiological measures. Although demonstrations may improve retention of information concerning simple procedures, the lecture format is more effective for complex information. (CFR)

The study compared the task demonstration model and the standard prompting hierarchy in training 8 persons (ages 16-21) with moderate or severe mental retardation on a discrimination task. The task demonstration model was found to be superior during both training and generalization phases. (DB)

This research investigated the value students attached to the laboratory activities while studying physics using the learning cycle curriculum construction and teaching procedures. Among the procedures used to supply students laboratory data were video-taped demonstrations, "live" teacher demonstration, presenting data in written form…

Describes a demonstration procedure using controlled reduction potentials to predict observed color changes which are then experimentally verified. Demonstrates the usefulness of this procedure in helping students understand LeChatelier's principle and the solubilit rule "like dissolves like." (CW)

Investigated the effect of mathematics instruction with the aid of microcomputer illustrations on the achievement of college students enrolled in an intermediate algebra course. There was a treatment effect on the comprehensive final examination. (YP)

Studies in Science Education is an international review of research for all who are interested in the educational dimensions of science. This issue contains these articles: "Teaching about Science, Technology and Society at the Secondary School Level in the United States. An Educational Dilemma for the 1980s" (Mary C. McConnell); Science…

Details three demonstrations for use in chemistry classrooms. Includes: "A Demonstration of Corrosion by Differential Aeration"; "A Simple Demonstration of the Activation Energy Concept"; and "A Boiling Demonstration at Room Temperature." Each description includes equipment, materials, and methods. (CW)

Describes a demonstration of a practical application of electrochemistry. Discusses the set-up, materials, and theatrical attributes of this demonstration. (CW)

This study evaluated the Task Demonstration Model for teaching discrimination skills with three teachers and their students (adolescents and young adults with moderate to severe mental retardation). The intervention required students to respond simultaneously. Students increased their percentage and rate of correct responding as well as their…

Describes a simple redox reaction that occurs between potassium permanganate and oxalic acid that can be used to prepare an interesting disappearing ink for demonstrating kinetics for introductory chemistry. Discusses laboratory procedures and factors that influence disappearance times. (CW)

Discusses some of the drawbacks of using a demonstration of the electrolysis of water to illustrate the interconversion between electrical and chemical energy. Illustrates a simple apparatus allowing demonstration of this concept while overcoming these drawbacks. (CW)

Maintains that having students estimate the size and width of a class waste paper can (placed on a desk) is a simple and effective way of illustrating perceptual distortion. Tests show that people will consistently overestimate the height of the can, allowing for a useful discussion on sensory distortion. (MJP)

Provides a brief overview of single-subject research designs. This method exercises its power by examining changes in single subjects' responses over time across experimental conditions. Describes a classroom project in which students collect repeated measures of their own behavior and graph the data. (MJP)

Argues that, even for young children, analogies offer conceptual models for supporting the development of understanding. Compared children's understanding of current electricity after instruction with and without the inclusion of analogies. Children receiving the analogies exhibited a broader understanding, especially concerning the process of…
