A study assessed the feasibility of sequential testing of medical students using standardized patients. Sequential testing passes students who score well on the first segment of the test thus eliminating additional student-standardized patient encounters. Subjects were six classes of Southern Illinois University students (n=404). Results strongly…

A modification of a test of the equality of nonindependent alpha reliability coefficients is proposed. It avoids the limitation that the product of the number of test parts times the number of subjects be quite large. Monte Carlo studies indicate that this test can be used in comparing interrater reliabilities. (SLD)

Inference is considered for the marginal distribution of "X" when ("X", "Y") has a truncated bivariate normal distribution. The "Y" variable is truncated, but only the "X" values are observed. A sample of 87 Otis test scores is shown to be well described by this model. (SLD)

Addresses some basic aspects of Archimedes' law. Focus is on potential energy relationships so as to elucidate some common misunderstandings and to facilitate making bridges with other physical topics. A spreadsheet model is used as a simulation tool. (Author/NB)

Describes a new concept for business education at Mercer County Community College called the International Business Practice Firm (IBPF), developed in response to employer calls for a more global approach in teaching American business students. Outlines the IBPF learning process, which teaches students business, technology, and "soft"…

Describes the structure and operations of a computer simulation model used in Papua New Guinea, developed with technical assistance from UNESCO. Notes that model establishes baseline data on student enrollments, teacher posts, and costs of education, and can be used to simulate policies under consideration and provide output on student flows,…

Examines the efficacy of nonresidential expanded tax base (ETB) approaches to school finance. A simulation estimated effects of statewide and regional nonresidential ETB approaches on measures of student equity for New York school districts. ETB approaches would improve student equity at no additional cost to the state and need not adversely…

Presents a hands-on activity designed to be a simulation of meiosis. (WRM)

Business undergraduates (n=261) participating in an assessment center simulation were evaluated by graduate students and faculty. Assessor-peer and assessor-self ratings lacked convergent and divergent validity, but self-peer ratings had both. (SK)

As part of the development of a scoring algorithm for a simulation-based dental hygiene initial licensure examination, this effort conducted a task analysis of the dental hygiene domain. Broad classes of behaviors that distinguish along the dental hygiene expert-novice continuum were identified and applied to the design of nine paper-based cases…

Describes "Glass-box Interpreter" a low-level program visualization tool called Bradman designed to provide a conceptual model of C program execution for novice programmers and makes visible aspects of the programming process normally hidden from the user. Presents an experiment that tests the efficacy of Bradman, and provides…

Contends that teachers must help students overcome their dislike of history by utilizing strategies that focus on children's interest in stories as a means for encouraging their students to connect with history. Discusses dramatization, children's literature, and storytelling, and provides a bibliography of children's literature. (CMK)

Describes the differences between normal and sequential lineups and their effects on eyewitnesses to crime. After a staged crime in a college lab, students were shown photographs in either normal lineup style or sequential style. 35% of eyewitnesses shown all photographs at the same time mistakenly picked an innocent person. Only 18% shown…

Discusses the evaluation of search engines and uses neural networks in stochastic simulation of the number of rejected Web pages per search query. Topics include the iterative radial basis functions (RBF) neural network; precision; response time; coverage; Boolean logic; regression models; crawling algorithms; and implications for search engine…

Introduces the concepts of online and offline sampling and highlights the role of online sampling in agent-based models of learning and development. Compares the strengths of each approach for modeling particular developmental phenomena and research questions. Describes a recent agent-based model of infant causal perception. Discusses limitations…
