Describes instructional use of a microcomputer version of the WORLD2 global population-ecology simulation. Reactions of students and instructors are discussed and a WORLD2 simulation assignment is appended. The BASIC version used by the author runs on Apple II, DOS 3.3, with 80 column board. (MBR)

Shows how a university utility building ("boiler house") is used in a chemical engineering course for computer simulations, mathematical modeling and process problem exercises. Student projects involving the facility are also discussed. (JN)

Two computer programs are given to provide simulations, for any value of n, to keep count of the frequency of the first significant digit. (MNS)

Explains how school planners can use microcomputers to create electronic spreadsheets that reduce the time required to calculate educational specifications. (MLF)

The present study compares the robustness of two different one way fixed-effects analysis of covariance (ANCOVA) models to investigate whether the model which uses a test statistic incorporating estimates of separate unequal regression slopes is more robust than the conventional model which assumes the slopes are equal. (Author/BW)

Describes an educational microcomputer gaming system for dealing with the acid rain problem in Western Europe and discusses its objectives, rules, problems, and future perspectives. Usefulness of gaming as an operational aid in formulating appropriate energy policies worldwide is emphasized. (MBR)

Discusses a computer simulation which: (1) describes an experiment investigating F=m/a; (2) generates data; (3) allows students to see the data; and (4) generates the equation with a least-squares fit. (JN)

Describes three computer programs which operate on Apple II+ microcomputers: (1) a menu-driven graph drawing program; (2) a simulation of the Millikan oil drop experiment; and (3) a program used to study the half-life of silver. (Instructions for obtaining the programs from the author are included.) (JN)

Presents a system that permits students to engage directly in the process of modelling and to learn some important lessons about models and classes of models. The system described currently runs on RML 380Z and 480Z, Apple II and IIe, and BBC model B microcomputers. (JN)

The author emphasizes the importance of understanding the value of computer technology in special education, specifically in developing expressive and receptive language, in providing opportunities for real-life problem-solving experiences through simulations, in facilitating basic functioning, and in providing recreational alternatives.…

Describes how microcomputers can perform very demanding/large-scale physics calculations at speeds not much slower than those of modern, full-size computers. Among the examples provided are a Monte Carlo simulation of the three-dimensional Ising model and a program (for the Apple microcomputer) using the time-independent Schrodinger Equation. (JN)

A positive correlation has been found between laptops and student achievement. Laptops are similar to Personal Digital Assistants (PDAs) in many respects. This study seeks to determine the effect of PDA usage on high school student academic achievement. It was hypothesized that a positive correlation between PDA usage and academic achievement in…

Because of perceived advantages, simulations are increasingly being used for performance-based training. This is a review of computer simulation as a learning tool, and its application within the context of disaster preparedness. Concepts from established learning theory are examined and research verifiable by empirical data is referenced. To…

The Centers for Disease Control (CDC) estimates that nearly 20 million Americans suffer from asthma, 6.3 million of which are children (Centers for Disease Control and Prevention, 2004). It is not merely an annoyance disease, as is commonly believed. Asthma kills. It takes more than 5,000 American lives each year (Asthma Statistics in America,…

Studies an information retrieval system for bibliographic entries or abstracts using queries from the INSPEC database on the FOLIO system at Stanford University (California). Highlights include strategies for distributing indexes across a set of processors and for performing queries in parallel; inverted lists; simulations; local area networks;…
