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)

Describes a specialized course for entrepreneurship training for students interested in operating their own business. This one-hour, year-long course for seniors focuses on teaching students business planning and management competencies. The course involves computer simulations, development of a business plan, and simulated business operation. (CT)

Describes a computer program (for the IBM microcomputer) which simulates pulsatile events in the heart in time frames that approach the speed of physiological events. The program also simulates the experimental laboratory in which the mechanics of an isolated heart can be studied. (Author/JN)

Four experiments involving 180 undergraduates evaluated the effectiveness of computer graphics in improving estimates for algebra word problems. Variations in the simulation resulted in successful and unsuccessful programs as measured by the frequency with which students improved their estimates. Quality of feedback to students while learning is…

Describes an experiment which allows students to identify the nature of the time-course for chymotrypsin and to obtain mechanistic information on the two kinetic phases in terms of their concentration dependence. Also describes the computer simulation (available from the author) used in the experiment. (JN)

Discusses the theoretical foundations, history, and advantages of educational simulations. Describes two computer simulation programs. (FL)

Discusses factors which determine whether there is a need for simulation and objectives associated with a simulation effort. Also discusses characteristics of existing software packages which determine if instructors should use the software or develop their own software for the particular problem under analysis. (JN)

The study summarized in this paper explored policies for improving open online content development projects with respect to growing the development community and improving the quantity and quality of materials developed. The study made use of dynamic feedback simulation and interviews with the members of an established content development…

Maximum likelihood and Bayesian estimates of proficiency, typically used in adaptive testing, use item weights that depend on test taker proficiency to estimate test taker proficiency. In this study, several methods were explored through computer simulation using fixed item weights, which depend mainly on the items difficulty. The simpler scores…

Many imputation techniques and imputation software packages have been developed over the years to deal with missing data. Different methods may work well under different circumstances, and it is advisable to conduct a sensitivity analysis when choosing an imputation method for a particular survey. This study reviewed about 30 imputation methods…

This study investigated changes in students' cognitive reasoning as they analyzed the dynamics of a rainforest ecosystem (El Yunque) in the aftermath of a hurricane in Puerto Rico. Students explore the virtual rainforest to study what happened to a type of frog after the hurricane. The culminating event is a simulation in which students manipulate…
