A brief package of subroutines (which can be typed in 15 minutes) enables a standard Apple II Plus, IIc, or IIe microcomputer to simulate a pen-plotter. Techniques for using this package in introductory engineering graphics courses are described. A sample program (which draws an oblique line) containing the subroutines is included. (Author/JN)

Two treatments--lecture and discussion about legal responsibilities toward the handicapped and a handicapped student simulation activity--promoted adaptability and flexibility in lesson plans in 117 regular secondary education undergraduates despite lack of evidence that the adaptations were integrated into lesson plans for the whole class.

Two computer simulation programs have been developed as instructional aids for preparation of special education teachers: one to assist teachers of the mildly disabled in selecting precise, databased solutions to classroom learning and behavior problems and another to prepare teachers to use direct, curricular-based assessments and to evaluate…

Rationale for use of simulations and games. Emphasizes game use in economics, particularly consumer education and studies at the secondary level. (LS)

This paper discusses two topics related to diagnostic score reporting for credentialing examinations. The first deals with various ways to compute subscores for credentialing examinations. The second addresses some pertinent factors to consider when presenting diagnostic results. To illustrate these issues, a sample set of subscores is used. This…

Using simulated data, the MULTILOG and PARSCALE software packages were compared for their recovery of item and trait parameters under the graded response and generalized partial credit item response theory models. The shape of the latent population distribution (normal, skewed, or uniform) and the sample size (250 or 500) were varied. Parameter…

This lesson plan offers students the opportunity to participate in the three basic economic systems (market, command, and tradition). By working in each of the systems, students will internalize the fundamental values present in each system and will gain insights into the basic advantages and disadvantages of each system. The lesson plan provides…

This lesson plan features a classroom simulation that helps students understand a command economic system. The lesson plan states a purpose; gives student educational objectives; suggests a time duration for the activity; lists materials needed; and outlines a step-by-step teaching procedure. Instructions for a research and writing homework…

A special case of the homogeneity of effect size test, as applied to pairwise comparisons of standardized mean differences, was evaluated. Procedures for comparing pairs of pretest to posttest effect sizes, as well as pairs of treatment versus control group effect sizes, were examined. Monte Carlo simulation was used to generate Type I error rates…

Research was conducted to provide educational researchers with a choice of pairwise multiple comparison procedures (P-MCPs) to use with single group repeated measures designs. The following were studied through two Monte Carlo (MC) simulations: (1) The T procedure of J. W. Tukey (1953); (2) a modification of Tukey's T (G. Keppel, 1973); (3) the…

Potential solutions to applied measurement problems are commonly evaluated using simulated data, largely because it is often impossible, difficult, or prohibitively expensive to supply the needed volumes of real data. However, answers proved by simulation studied generalize real-world problems only to the extent that the simulated data resembles…

An approach that is currently gaining popularity in educational measurement is one that treats item response theory (IRT) as a special case of nonlinear factor analysis (NLFA). A brief overview is provided of some of the research that has examined the relationship between IRT and NLFA. Three NLFA models are outlined, emphasizing their major…

The purpose of this study was to estimate the extent to which recording variability among standardized patients (SPs) has an impact on classification consistency with data sets simulated to reflect performances on a large-scale clinical skills examination. SPs are laypersons trained to portray patients in clinical encounters (cases) and to record…

This report presents basic theoretical and methodological assumptions for investigating the relationship between competence and qualifications by means of simulation tasks. An analysis of the types of tasks that have been used in the study of problem solving psychology serves as a background for an exposition of the relationship between competence…

In this study, the effect of appended pretesting was evaluated with regard to item statistics and examinee scores for groups of items that were pretested as part of a large-scale operational testing program. In appended pretesting, items are administered in a separately timed section at the end of an operational test battery. Two evaluations were…
