A program called SemCalc is detailed that enables people to use the computer as a tool to solve word, story, estimation, and simple algebra problems. SemCalc is seen as an example of a computer program that is a tool, with no curricular agenda of its own. (MP)

Two uses of computers are outlined. The first discusses and presents a model of a program which is designed to teach students the reasoning involved in solving certain problems. The second looks at the ability of computers to count at high rates of speed, as a start for student explorations. (MP)

Explains the three main concepts of the system dynamics approach to model building (dynamics, feedback, and systems) and the basic steps to problem solving by simulation applicable to all educational levels. Some DYNAMO commands are briefly described. (EAO)

"Big Business" is a series of computer simulations designed to give players a chance to compete in the practical world of business and finance. The basic elements of the simulations and versions designed for home use, middle school students, and high school students are described. (Author/JN)

"Lemonade" is one in a series of simulations designed to permit exploration of elementary concepts in economics. The nature of the simulation, problem-solving skills fostered, and suggestions for use of the program in the classroom are discussed. (Author/JN)

Discusses the use of microcomputers and software as problem-solving tools, including comments on "TK! Solver," automatic problem-solving program (reviewed in detail on pp.84-86 in this same issue). Also discusses problem-solving approaches to bridge the disciplines, such as music/physics, junior high science/mathematics (genetics),…

Discusses steps involved in model building and simulation: understanding a problem, building a model, and simulation. Includes a mathematical model (focusing on a problem dealing with influenza) written in the DYNAMO computer language, developed specifically for writing simulation models. (Author/JN)

A computer software package designed to lead students through exploration using ancient sailing ships is reviewed, focusing on features, educational value, design quality, written materials, and ease of use. The price was seen to be too high for most individual teachers or parents. (MP)

Reviews an educationally valuable and reasonably well-designed simulation of volcanic activity in an imaginary land. VOLCANOES creates an excellent context for learning information about volcanoes and for developing skills and practicing methods needed to study behavior of volcanoes. (Author/JN)

Provides a detailed description of Lemonade, a business game designed to introduce elementary and secondary students to the basics of business; i.e., problem solving strategies, hypothesis formulation and testing, trend analysis, prediction, comparative analysis, and effects of such factors as advertising and climatic conditions on sales and…

Describes some commands, simple programing procedures, and applications of the programing language LOGO, including its powerful recursive feature and its value in teaching problem solving. A listing of LOGO graphics packages includes details of software and print materials, prices, and microcomputers that will support the packages. (EAO)
