Examined the relative performance of two commonly used methods of parameter estimation in factor analysis, maximum likelihood (ML) and ordinary least squares (OLS) through simulation. In situations with a moderate amount of error, ML often failed to recover the weak factor while OLS succeeded. Also presented an example using empirical data. (SLD)

Compares the performance of 85 freshmen and sophomores enrolled in two sections of an online introductory networking and telecommunications course. One section utilized a network simulation package that allows the student to build and send data through different network configurations; the second section used a static network diagramming software…

A 3-year study of 50 health occupations and trade and industrial preservice teachers in an alternative teacher education program included a simulation work exercise and analysis of instructional materials. Informal workplace learning resulted in implicit knowledge in the first year of practice. Critical practice was shown to be an important model…

A study assessed the effectiveness of a business administration simulation exercise designed to train students in problem solving, decision making, and interpersonal skills. Results of the simulation in a Slovenian institution with graduate students in international business are discussed, along with implications for incorporating the exercise…

A simulation study explored the effect of population distribution on maximum likelihood estimation (MLE) and expected a posteriori (EAP) estimation in computerized adaptive testing based on the rating scale model of D. Andrich (1978). The choice between EAP and MLE for particular situations is discussed. (SLD)

Studied the impact of changes in item difficulty on National Assessment of Educational Progress (NAEP) estimates over time through a Monte Carlo study that simulated the responses of 1990 NAEP mathematics respondents to 1990 and 1996 NAEP mathematics items. Results support the idea that these changes have not affected the NAEP trend line.…

Describes an integrated use of simulation/gaming in an English for Academic Purposes (EAP) class, analyzes benefits and drawbacks, and suggest how the technique could apply to other specific contexts. Explains how international students ran a simulation on gun control; discusses the debriefing process; and considers motivation, metacognitive…

Developed are simple recursion formulas for generating the exact distribution of the longest run of heads, both for a fair coin and for a biased coin. Discusses the applications of runs-related phenomena such as molecular biology, Markov chains, geometric variables, and random variables. (YP)

The effect of large, within-examinee item difficulty variability on estimates of the proportion of consistent classification of examinees into mastery categories was studied over 2 test administrations for 100 simulated examinees. The proportion of consistent classifications was adequately estimated using the technique proposed by M. Subkoviak…

Judgment analysis was used to determine whether 65 superintendents of large and medium school districts used all available information to make decisions about effective educational programs in simulated environments. Superintendents judged 75 numerical profiles of environmental conditions. Subjects relied on only part of the available information…

In a few select high schools in the U.S., supercomputers are allowing talented students to attempt sophisticated research projects using simultaneous simulations of nature, culture, and technology not achievable by ordinary microcomputers. Schools can get their students online by entering contests and seeking grants and partnerships with…

Investigates the effects of realism and perceived control on student satisfaction with the SuperShrink interview. Compares active/passive and computer/hardcopy conditions. Findings show students rate the computer versions as more satisfying. Suggests computers are superior to hardcopy simulations of human interactions. (Author/NL)

The acceptability of two different training methods (simulation training using a doll and simulation training on self) for teaching menstrual hygiene skills to young women with developmental disabilities was evaluated in two experiments. Results suggested that opinions about treatment acceptability should be obtained from both professional and…

Describes how to enhance the benefits of using the Carmen Sandiego educational software programs by building in generous amounts of creative fun and writing activities. Discusses journal writing, character sketches, letter writing, writing a book, and report writing. (RS)

Discussion of educational games that can be configured to accommodate changes in the structure of the game focuses on MANAGEMENT 500, a microcomputer-controlled prototype business simulation game. Three modes of learning that can be emphasized through a configurable simulation game are explained: learning by discovery, by perseverance, and by…
