Describes how a computer simulation is used with a laboratory experiment on the synthesis of urea in isolated hepatocytes. The simulation calculates the amount of urea formed and the amount of ammonium remaining as the concentrations of ornithine, citrulline, argininosuccinate, arginine, and aspartate are altered. (JN)

Describes an interactive simulation model which can be used to demonstrate population growth with discrete or overlapping populations and the effects of random, constant, or density-dependent mortality. The program listing (for Commodore PET 4032 microcomputer) is included. (Author/DH)

General guidelines are developed to assist practitioners in devising operational computerized adaptive testing systems based on the graded response model. The effects of the following major variables were examined: item pool size; stepsize used along the trait continuum until maximum likelihood estimation could be calculated; and stopping rule…

Describes a lesson that outlines a statistics/probability investigation into some aspects of past performance in snooker (a billiards game) using the random number generator on a graphing calculator. (MKR)

This digest discusses the nature of interactive videodiscs and their educational applications, provides information about educational uses of videodisc technology, and presents lists of videodisc-related organizations, books, and periodicals. A general description of a reflective optical laser videodisc is presented, as well as the equipment…

One way in which a computer simulation can convince students of the validity of formulas for the density and distributive functions of the sum of two variables is described. Four computer program listings are included. (MNS)

Describes an oxygen transport model computer program (written in Applesoft BASIC) which uses such variables as amount of time lapse from beginning of the simulation, arterial blood oxygen concentration, alveolar oxygen pressure, and venous blood oxygen concentration and pressure. Includes information on obtaining the program and its documentation.…

Simulations can help students apply basic science knowledge (which they are acquiring concurrently) to the identification and management of the physiological, metabolic, and/or anatomic problem(s) underlying the signs and the symptoms of a specific "simulated patient." The design, development, and production of these simulations are described. (JN)

Describes a program which simulates animal pharmacology experiments involving "all-or-none" responses. Use of the Applesoft BASIC program in the pharmacology teaching laboratory provides students with a rapid and economical way to gain experience in the design and statistical analysis of quantal dose-response experiments. Information on…

RESPSYST is a computer program (written in BASICA and using MS-DOS/PC-DOS microcomputers) incorporating more than 20 of the factors that determine gas transport by the cardio-respiratory system. The five-part program discusses most of these factors, provides several question/answer sections, and relies heavily on graphics to demonstrate…

Examines what is currently being done in Israel related to software development, discussing: (1) TOAM (a Hebrew acronym for "drill and parctice with the Help of the Computer, an elementary arithmetic program; (2) MENTOR (an authoring language); and (3) a role playing simulation. (JN)

A computer program and simulations that can be used to help college economics students understand dynamic economic processes are described. (RM)

An exercise simulating the tossing of N dice is described. Calculation of expected gain and extension to a two-person game are each discussed. (MNS)

Discusses the use of computer adventure games and simulations to teach children critical thinking. Provides lists of mid-elementary to adult-level adventure games (with manufacturer and current price) and software helpful in teaching critical thinking (indicating name of package, manufacturer, age level, and current price for each entry). (JN)

The simulation of titration and qualitative analysis experiments by means of computer-driven laser videodisc recordings is described. (JN)
