Computational modeling and thinking skill sets were previously relegated to computer scientists and programmers. As a result, computational tools are largely unfamiliar to K-12 science teachers and students. Using Mathematical and Computational Thinking and Developing and Using Models were included in the "Next Generation Science…

EngQuest, an initiative of Engineers Australia, provides an exciting, non-competitive way for students to participate in free, fun and educational engineering activities involving mathematics, science and technology. This article describes a project designed to teach middle school students how to construct a water catchment system. Water…

The concept of specificity of enzyme action can potentially be abstract for some students as they fail to appreciate how the three-dimensional configuration of enzymes and the active sites confer perfect fit for specific substrates. In science text books, the specificity of enzyme-substrate binding is typically likened to the action of a lock and…

With just a few materials, building a paper model of the International Space Station (ISS) can become an excellent group, troop, or class project. This publication contains a brief overview of the ISS, its parts, the science that occurs on board, instructions, and extensions for an interdisciplinary technology experience. Discover more about the…

The Coach system, a computer simulation of a human tutor, was constructed with the goal of obtaining a better understanding about how a tutor interprets the student's behavior, diagnoses difficulties and gives advice to a student learning a simple computer programming language. Coach is based on a hierarchy of active schemas representing the…

A simple teaching model, designed to show rapidly which are the principal factors in population growth and how they are related, is presented. The apparatus described allows students to play several different active roles. (MP)

Described is a computer simulation designed to introduce students to some of the intricate relationships between the many factors involved in international economics. (MP)

Describes the use of EXPER SIM (experimental simulation) as an instructional tool in speech communication research. Several sample models are offered along with a discussion of the advantages and drawbacks of using the computer for social science research. (JMF)

A model that can be used to show the arrangement of light and heavy chains, disulfide linkages, domains, and subclass variations in antibodies is given. It can be constructed and modified to illustrate Fab, F(ab')2, and Fc fragments, single domain and bifunctional antibodies, and labeling of antibodies. (Author)

Due to his work to determine how cholera was spread in the 18th century, John Snow (1813-1858) has been hailed as the father of modern epidemiology. This article presents an inquiry model based on his life and work, which teachers can use to develop a series of biology lessons involving the history and nature of science. The lessons presented use…

The macroeconomic model in Ray C. Fair's textbook, "Specification, Estimation, and Analysis of Macroeconometric Models" (Cambridge: Harvard University Press, 1984), has been programed to run on a personal computer. The model consists of 128 equations. The model's potential for use as a teaching tool is discussed. (RM)

An economic simulation in which the classroom is organized like the world of work, with the teacher as employer and the students as paid employees; is an excellent way to prepare students for the world of work and to get them to help with routine classroom chores. (RM)

Describes an activity that would be useful for any level biology class discussing recombinant DNA technology to help students visualize the step-by-step process involved. (JRH)

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…

Presents a program to introduce fifth graders to everyday economic life by constructing a true-to-life simulation of an economic community. Students apply mathematics skills to managing a checking account, calculating electric bills, and managing shops using computers. (MDH)
