Discusses the advantages and disadvantages of three types of computer instruction in engineering education: tutorial, design, and simulations. Includes comments on efficiency, student acceptance, and scheduling problems. (MLH)

Discusses the use of a simulation language designed to teach dynamic behavior to engineering students via a digital computer. Describes specific applications of the language and the costs of implementing digital dynamic simulation. (MLH)

Describes two types of computer-based experiments: simulation (which assumes no student knowledge of the workings of the computer program) is recommended for experiments aimed at inductive reasoning; and modeling (which assumes student understanding of the computer program) is recommended for deductive processes. (MLH)

Sim One is a computer-controlled patient, a sophisticated simulator developed by the University of Southern California School of Medicine. This article summarizes fifteen cost-effectiveness studies conducted over a 2-year period. Savings with the use of Sim One were found to justify the cost within a short period. (JT)

Describes an experiment in which the beam of X-rays is simulated through the use of a laser as a monochromatic light source and the crystal is replaced by photographically prepared masks. A strong diffraction pattern as large as 20 cm. can be obtained. (GS)

Arguing that operations research is not as difficult and forbidding as its reputation implies, and that many problems lend themselves to analysis using common sense, the author provides examples which might be used in a secondary school classroom. (SD)

The teacher developed audit simulation takes the student away from the textbook into the real work situation. (BP)

The purpose of this simulation is to develop in students an awareness of a fundamental legal principle: that procedure is the essence of justice. (Author)

By using a computer to simulate experimental situations, engineering laboratory courses can provide more ambitious experiments as well as experiments demanding more calculations. (SD)

A course in applied statistics for social science students provides for students designing experiments at an interactive terminal. (SD)

Simulates the problems of rocket propulsion, hovering, and soft landing. (GS)

A computer network serves 53 schools and colleges in North Carolina; Essex County College in New Jersey has an on-line computer registration system that is used by students and administrators to enter information or ask questions. (Author/MLF)

Lord's bias function and the weighted likelihood estimation method are effective in reducing the bias of the maximum likelihood estimate of an examinee's ability under the assumption that the true item parameters are known. This paper presents simulation studies to determine the effectiveness of these two methods in reducing the bias when the item…

It is a widely held belief that an anchor test used in equating should be a miniature version (or "minitest") of the tests to be equated; that is, the anchor test should be proportionally representative of the two tests in content and statistical characteristics. This paper examines the scientific foundation of this belief, especially…
