A sequence of simulations was carried out to aid in the diagnosis and interpretation of equating differences found between random and matched (nonrandom) samples for four commonly used equating procedures: (1) Tucker linear observed-score equating; (2) Levine equally reliable linear observed-score equating; (3) equipercentile curvilinear…

The interest in the application of large-scale adaptive testing for secure tests has served to focus attention on issues that arise when theoretical advances are made operational. Many such issues in the application of large-scale adaptive testing for secure tests have more to do with changes in testing conditions than with testing paradigms. One…

Conventional wisdom suggests the omnibus F-test needs to be significant before conducting post-hoc pairwise multiple comparisons. However, there is little empirical evidence supporting this practice. Protected tests are conducted only after a significant omnibus F-test while unprotected tests are conducted without regard to the significance of the…

Describes a program system which was developed for the purpose of making estimates about the nature of the distribution of test scores which will result from an administration of a test composed of items of which estimates of item-difficulty and discrimination are available. (Author/RC)

The Individual Scaling with Individual Subjects (ISIS) procedure appears to be a viable implementation of an incomplete design for collecting real as well as simulated data. Applied to a multidimensional set of data, it reduced the number of judgments required by more than half and yet gave the same number of dimensions. (Author/RC)

Traditional methods have hitherto neglected the situation in foreign language teaching. The situation - a means of tying closely together the use of language (expression) with the conditions for the use of this language (situation) - represents only a substitute, indeed, for the real situation, but does fill a significant place in language…

Actors have been trained to portray patients with a variety of physical and emotional disorders for the purpose of teaching and evaluating clinical skills. Suggests that actors considered for simulations of patients be screened on the basis of sufficient acting experience and motivation for the role. (Author/PG)

A simulated mental hospital, which ran for 56 hours over a period of two consecutive weekends is described as an effective teaching device for an undergraduate course in clinical psychology. (JH)

Described is the development of graphic materials for teaching fundamental concepts in chemistry. Computer simulation provides data and visual materials to aid understanding. (RH)

The writer examines his own initial experiences in gaming and simulation in a search for standard game forms, and concludes that, when these are linked to a classification of objectives, they can be a constructive and useful expression of analysis. (Author)

Simulating a confrontation at a convention or other meetings can prepare participants to be ready for the real thing, says this author. He raises pertinent questions to simulate thinking on this possibility. (Editor)

This career exploration instructional booklet on the occupation of a postal employee is one of several resulting from the rural southwestern Colorado CEPAC Project (Career Education Process of Attitude Change). The content includes: (1) A brief presentation of the job functions of five types of postal employees, the traits and qualifications…
