Describes a problem formulated by fourth-grade students about having more pizza for lunch, and the clarifying, predicting, modeling, simulating, comparing, and extending activities that occurred in addressing the problem from a probabilistic perspective. (MKR)

States that teaching the concepts of evolution to secondary school and college students is difficult. Presents a playing card game-based simulation that teaches the complex idea of natural selection in a simple, nonthreatening way. Includes three figures, one table, and step-by-step instructional procedures. (CFR)

The validity of vignettes used to elicit subject responses in social science research is examined in a study of the validity of a group of patient assault vignettes seen by 12 persons with experience in patient care. A model for establishing the validity of vignettes is proposed. (SLD)

Factors that contribute to different perspectives and attitudes toward learning in both teachers and students are discussed, and MARKETING SIMULATION exercise for undergraduates at University of Lancaster is described. An evaluation of instructional effectiveness of this exercise is reported with emphasis on the impact of hidden curricula on…

This replication of a comparison of student perceptions and attitudes toward learning from case studies and from management simulations found that students perceive the simulation exercise to be superior to case study discussions for learning skills in the business policy course. Because these results contradict the findings of the original study,…

Presents study results examining behavior associated with preservation and destruction of slowly regenerating natural resources by using commons dilemma simulation games. Reports that neither environmental concern nor proenvironmental behaviors were related to commons dilemma performance. Concludes that cooperation and competition were better…

Four blind adults explored the spatial layout of landmarks in a large-scale space utilizing a microcomputer simulation of the environment and a tactile graphic aid of a similar environment. Although subjects learned the landmarks' locations faster using the tactile graphic aid, the accuracy of their spatial knowledge was equal with both…

Discussion of design principles in creating interactive video simulations for second-language learning focuses on two interactive video simulations on the Eurocentres Videodisc (ECVD). Four design principles are explained, instructional procedures involved in the ECVD are described, and learners' reactions are discussed. (four references) (LRW)

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)

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…
