It is common to assume during statistical analysis of a multiscale assessment that the assessment has simple structure or that it is composed of several unidimensional subtests. Under this assumption, both the unidimensional and multidimensional approaches can be used to estimate item parameters. This paper theoretically demonstrates that these…

This instructional unit is comprised of four lessons dealing with conducting a four part class in basic rock climbing. The class is suitable, with modifications, for small private parties, small groups such as the Boy Scouts, or larger, organized groups such as climbing clubs. Four instructional methods are used: instructional media,…

To assess the effect on discriminant analysis in terms of correct classification into two groups, the following parameters were systematically altered using Monte Carlo techniques: sample sizes; proportions of one group to the other; number of independent variables; and covariance matrices. The pairing of the off diagonals (or covariances) with…

The state of research on the use of audiotape recordings for teaching purposes is reviewed, and 10 strategies are discussed in detail: (1) verbal stimulation of activity; (2) nonverbal stimulation of activity; (3) stimulation of relaxation; (4) real time conservation of acoustic reality; (5) reportage (simulation and condensation of reality); (6)…

Two strategies, derived from J. P. Schaffer (1986), were compared as tests of significance for a complete set of planned orthogonal contrasts. The procedures both maintain an experimentwise error rate at or below alpha, but differ in the manner in which they test the contrast with the largest observed difference. One approach proceeds directly to…

This book presents a practical guide on how to improve the communication and cultural awareness among culturally different people. It is organized into three parts which correspond to the three stages of multicultural development: awareness, knowledge, and skills. The first part emphasize the awareness of culturally learned opinions, attitudes,…

This doctoral dissertation examines the extent to which general case simulation instruction on a janitorial task sequence and a housekeeping task sequence conducted with four secondary and postsecondary age persons with moderate mental retardation resulted in generalized performance. A multiple baseline design across subjects and behaviors was…

The use of healthy individuals acting as simulated patients for the purpose of clinical teaching is discussed. The term "standardized patients" is used to refer to training the individual to present a standard, repeatable stimulus. Some evidence suggests that simulated patients possess high fidelity (i.e., closely approximate real…

This simulation is intended for use as a culminating activity after students have been exposed to personal and/or business letter writing, use of reference manuals, typing of letters, mailing procedures, typing of numbers, punctuation practice, and filing procedures. Stated objectives are to enable students to type a mailable letter; to inspect,…

The connection between item bias and test scores was investigated using a simulation approach. Two samples of hypothetical examinees were simulated using an item response theory model. The two samples were identical, except that the mean theta value 1 sample was 5 less than the other. The simulated tests consisted of 50 items with characteristics…

An indoor simulated archaeology site for use in a college level introductory archaeology course is described. Housed in the basement of a building on campus, the site simulates an eight-layered French rock shelter. Layers contain "remains" of a microband of Neanderthals, a Lower and Upper Aurignacian group, an Upper Perigordian group, Magdalenian…

Described are two computer problems used to provide graphic displays of data in undergraduate chemistry classes. (RH)
