Investigates the problem of finding the expected number of questions necessary to identify 1 out of a set of 30 attribute blocks. Solutions include the use of a tree diagram or a computer simulation. Generalizes the problem for increased numbers of attributes. (MDH)

Describes a simulation-oriented computer microworld named CHANCE used to overcome the limitations of physical materials for experiments in teaching and learning introductory probability. Results of a teaching experiment conducted with four middle school and high school students are discussed. (15 references) (LZ)

Two new methods of estimating the mean population correlation (M) and the standard deviation of population correlations (SD) were suggested and tested by Monte Carlo simulations. Results show no consistent advantage to using the Pearson correlation or Fisher's Z in estimating M or SD; estimates from all methods are similar. (SLD)

A project called Image Processing for Teaching provides real-world experiences for students with deafness or hearing impairments, through computerized image exploration. Students use computer technology to judge the impact of building a dam, study gravity through the flight of a basketball, and understand scientific concepts that previously…

Describes "Story Producer for InteractivE Learning" (SPIEL) a multimedia retrieval system for educational stories, and its integration into an architecture called "Guided Social Simulation" (GuSS), for teaching complex social skills such as management, diplomacy, or selling. Highlights include an example of the use of SPIEL,…

A new item-fit index is proposed that is both a descriptive measure of deviance of single items and an index for statistical inference. This index is based on assumptions of the dichotomous and polytomous Rasch models for items with ordered categories. A simulation study is described. (SLD)

Describes a study that examined the effectiveness of implied boolean searches using personal author surnames plus first and/or last title words to retrieve an entry from a simulated online public access catalog (OPAC). Implications for the design of OPACs are discussed, and further research is suggested. (LRW)

Illustrates how to use computer simulation models in statistics to study the quality of an estimation procedure and concurrently the subtle concepts of randomness and convergence. Special emphasis is given to the use of graphical representations. (MKR)

Develops and evaluates the linkage of the Armed Services Vocational Aptitude Battery to the mathematics scale of the National Assessment of Educational Progress. The accuracy of the proficiency distribution estimated from the projection was close to the accuracy of the distribution estimated from the large scale assessment. (SLD)

Simulated data were used to investigate the impact of characteristics of threshold values (number, symmetry, and distance between adjacent threshold values) and delta values on the distribution of item information in the successive intervals Rasch model. Implications for computerized adaptive attitude measurement are discussed. (SLD)

Computers may someday replace teachers at essay grading. In recent research, a blind test has demonstrated that a computer can simulate the judgment of a group of human judges on a brand-new set of essays. Moreover, the PEG (Project Essay Grade) program can do a better (and more cost-effective) job than the usual two human readers while providing…

The impact of detailed information on closed head injury (CHI) and Minnesota Multiphasic Personality Inventory-2 (MMPI-2) validity scales on malingering psychological symptoms of CHI on the MMPI-2 was studied in an analog experiment with 270 undergraduates. Results suggest the impact of such coaching on simulation of CHI. (SLD)

Examines two methods of conducting an employment interviewing training exercise for interviewees. Compares instructor-facilitated and peer-facilitated exercises specifically. Discusses the advantages and disadvantages of each. Concludes that instructor-facilitated training was preferred over peer-facilitated training, and suggests directions for…

British high school students (n=120) participated in a management exercise in which teams prepared a marketing contract, drafted a promotional leaflet in French, and gave a marketing presentation to hotel management. The exercise developed teamwork, decision making, and leadership, as well as other skills valued in the workplace: bilingualism,…

Discusses the current use of simulation and gaming in a variety of settings. Describes advances in technology that facilitate the use of simulation and gaming, including computer power, computer networks, software, object-oriented programming, video, multimedia, virtual reality, and artificial intelligence. Considers the future use of simulation…
