Effects of different weighting schemes on selecting the optimal number of observations in multivariate-multifacet generalizability designs are studied when cost constraints are imposed. Comparison of four schemes through simulation indicates that all four produce similar optimal values and that reliability should be similar. (SLD)

Rasch model total-fit statistics and between-item fit statistics were compared for their ability to detect measurement disturbances through the use of simulated data. Results indicate that the between-fit statistic appears more sensitive to systematic measurement disturbances and the total-fit statistic is more sensitive to random measurement…

Describes activities that allow students to work cooperatively to analyze and study evidence from crime scenes and archaeological digs. The activities demonstrate to students the interdependence of a variety of disciplines in the real world. (ZWH)

A simulation exercise consisting of 12 stages corresponding to the life-stages of an enterprise is used as a language-learning technique for business French. The exercise develops both language and networking skills while presenting a creative challenge to students. (MSE)

An extension to the partial credit model, the linear partial credit model, is considered under the assumption of a certain linear decomposition of the item x category parameters into basic parameters. A conditional maximum likelihood algorithm for estimating basic parameters is presented and illustrated with simulation and an empirical study. (SLD)

Activity in which students act out process of protein synthesis is described. An overview of the events and a demonstration of some simple errors that may occur in the process are included. The simulation has been designed so that each student in a class has at least 1 specific role to play and requires from 20 to 40 students. (KR)

Describes exercises that can uncover the assumptions underlying educational practice: (1) scenario analysis; (2) critical debate; (3) simulations of crisis decisions; (4) identifying heroes and villains; and (5) analysis of critical incidents. (SK)

Two studies evaluated the use of either in vivo training or simulation prior to in vivo, as methods for training 8 students (ages 10-19) with moderate disabilities to cross streets and to use public pay telephones. Results suggested that prior simulation training did not appear to either facilitate or inhibit later in vivo instruction. (DB)

Presents results of simulations that were conducted to test the effects of errors in estimation of individual term probabilities on the performance of a probabilistic information retrieval (PIR) system. Assigning index terms to documents is described; an information retrieval system called Helpnet is explained; and relevance, ranking, and…

Describes the International Business Negotiation Simulations (IBNS), a series of workshops which use a computer-managed teleconferencing-based simulation designed to teach business executives how to negotiate successfully in a cross-cultural environment. Team structures and roles are described, the telecommunications interface is explained, and…

A combination of computer, videodisk, and voice-recognition technology lets Georgetown University medical students ask questions of an electronic "patient" who appears on a television monitor and appears to respond. Students can order laboratory tests and study patient behavior inside and outside the hospital. Simulations use actors or…

The effect of reducing the number of score groups in the matching criterion of the Mantel-Haenszel procedure when screening for differential item functioning was investigated with a simulated data set. Results suggest that more than modest reductions cannot be recommended when ability distributions of reference and focal groups differ. (SLD)

Adult and continuing education tutors (n=50) surveyed favored a range of teaching techniques, including experiential, but some viewed the latter as unsuitable. Role play, simulation, and gaming were not frequently used. Tutors preferred to develop their own methods and materials and believed their students expected traditional methods. (SK)

A simulated distance learning experience showed planners that problems exist and are manageable, that it is difficult to change teaching methodologies once a class has begun, that the experience can incorporate several teaching methods but they must be well-planned in advance, and that teacher training is essential. (JOW)

To complement and strengthen its educational leadership program, East Tennessee State University, along with Brigham Young University, Florida State University, and Virginia Tech, formed a liaison with NASSP to help expand and refine administrative skills in decision making, leadership, sensitivity, problem solving, communication, judgment, and…
