Outlines the differences between the traditional and modern theoretical models of demand for money. States that the two models are often used interchangeably in textbooks, causing ambiguity. Argues against the use of linear specifications that imply that income velocity can increase without limit and that autonomous components of aggregate demand…

This essay summarizes how distinct sociological traditions account for cycles of censorship. Positivist or functionalist modes of analysis are contrasted with the stances of symbolic interactionist researchers. Understanding of cycles in the production of obscenity and censorship is needed to discover appropriate social action. (CJH)

Discusses two concrete models that have been useful in helping students understand operations with percentages. Includes information on materials needed, procedures for students, limitations, and instructional strategies. (JN)

The third in a series of six articles on the use of different models for developing creativity and instructional materials focuses on the sociodrama model. (SBH)

Discusses the adoption of a notation system that is generalizable to all instructional designers and will allow and encourage a common communication base. Ten instructional design models are discussed as systems approaches to instructional design. (JEG)

Suggests a common format for analyzing and evaluating learning systems which takes into account costs, skill requirements and sequence, instructional techniques and requirements, motivational factors, and evaluation. (RAO)

An inquiry model of material development and selection for special education teachers is presented. The following selection guidelines are described: identify the target population; define the purpose of the material; consider the format, methodology, and construction of the material; and determine how the material is to be used. An example of an…

Proposes a method for evaluating courseware as an integral part of curriculum, based both on "curriculum commonplaces" (the curriculum content and all that surrounds it) and on educational values and beliefs; an evaluative matrix is offered, with the commonplaces arrayed along one axis, values and beliefs along the other. (MCG)

Based on both practical experience and theoretical studies, this manual provides the foundation for the design of effective distance education teaching materials. An overview presents an outline model of major design considerations for correspondence materials that provides a context for design decisions, with categories chosen to assist in the…

Intended for use with college students in introductory macroeconomics or American economic history courses, these two computer simulations of two basic macroeconomic models--a simple Keynesian-type model and a quantity-theory-of-money model--present largely incompatible explanations of the Great Depression. Written in Basic, the simulations are…

Operationalizes the theoretical foundation of Gagne's model as a component in the instructional design process. The description of design techniques includes a sample media analysis, and a sample sequence worksheet. (JEG)

Outlined are two experiments using liquid membranes that illustrate carrier-facilitated transport, where chemical species are ushered across the membrane by selective "carrier" molecules residing in the membrane. The use of liquid membranes as models for studying and describing biological transport mechanisms is explored. (CS)

The concept of controlled experimentation is a skill that all students leaving high school should master. Teachers often attempt to find exciting and fun methods to expose students to this valuable skill. This science activity guide allows students to construct model rockets in an attempt to improve their abilities to conduct controlled…

Describes the construction of a model to show circumpolar stars. (BR)

Describes a laboratory exercise using relief models, aerial photographs, topographic maps, and cone studies to determine depth and thickness of a concealed mineralized zone. (MA)
