A sample of 72 students tested manufacturing simulation software about production planning. The package enriched learning, although compared to lecture only, no clear-cut advantages were perceived. Amount of time between lecture and lab experience did not affect learning or retention. (SK)

One-parameter and three-parameter item response theory (IRT) model estimates were compared with estimates obtained from two modified one-parameter models that incorporated a constant nonzero guessing parameter. Using small-sample simulation data (50, 100, and 200 simulated examinees), modified 1-parameter models were most effective in estimating…

Large scale studies of the psychometric characteristics of standardized-patient clinical examinations are reviewed, and recommendations for test improvement are offered, including (1) assessment of history taking, physical examination, and communication skills separately from diagnostic and management skills; (2) a mastery-testing framework for…

A review (HE 528 450) of large-scale studies of the psychometric characteristics of standardized-patient clinical examinations is commended for its clarity, thoroughness, and relevance. Issues of reliability, validity, scoring, reporting, and use of the tests are discussed further. (MSE)

Automated evaluation methods, used in medical school training programs, are discussed. The use of situational questions which help students to make connections between the biochemical knowledge acquired and its application in medical practice is proposed. Examples of these types of questions are included. (KR)

Describes a simulation method for estimating recall and fallout in a document retrieval system. Earlier research on simulating document retrieval systems is reviewed, examples are presented of the current method, a probabilistic justification of the method is given, theoretical concerns dealing with retrieval precision are discussed, and further…

Law students were asked to simulate, in writing, the thinking of a lawyer advising a client. Scripts produced by students and teachers revealed a pattern of repeated syllogisms, or an algorithm, contained within the macrostructure of situation-problem-solution. Variation depended upon the issues discussed or type of law studied. (28 references)…

A study investigated the performance of 6 successive medical school classes on 80 standardized-patient case examinations, looking for effects of student or standardized-patient gender on scores. Results showed no interaction of any practical consequence. Cases with gender-related concern (e.g., breast problems) also did not differentiate between…

A study investigated whether the more efficiently graded extended-matching questions were equivalent to short-answer questions in evaluating medical students' (n=98) ability to elicit physical findings and generate diagnoses and treatment plans, using standardized-patient examinations. The differences found in the two question types did not favor…

The University of Illinois' National Center for Supercomputing Applications, a cooperative effort of the National Science Foundation, University of Illinois, the state, and industry, offers training and support services in the use of technologically advanced computing for scientific research. The computers simulate physical phenomena that are…

Using simulated and real data, this study compares the performance of three methodologies for assessing unidimensionality: (1) DIMTEST; (2) the approach of Holland and Rosenbaum; and (3) nonlinear factor analysis. All three models correctly confirm unidimensionality, but they differ in their ability to detect the lack of unidimensionality.…

Describes results of a study of business school students that investigated the link between the ability of business simulation team participants to forecast financial and/or market-related outcomes and the actual results of their decision making. Profitability and forecasting errors are discussed, and implications for designing business…

The usefulness of a two-step version of the Mantel Haenszel procedure for distinguishing between differential item functioning (DIF) and item impact was studied by comparing the single-step and two-step procedures using a simulated data set. Results show changes in the identification rate for the two-step methods. (SLD)

Reviews the different types of models that can be used in groundwater modeling. Discusses the flow and contaminant transport models in the saturated zone, flow and contaminant transport in variably saturated flow regime, vapor transport, biotransformation models, multiphase models, optimization algorithms, and potentials pitfalls of using these…

Explains how training simulations can make on-the-job learning faster and safer by providing hands-on experience and controlled environments. Offers tips for assessing the costs and designing and effective simulation. (Author)
