With an increase in diverse cultures comes a responsibility for educators to become aware of their ethnocentric attitudes that influence increasingly diverse classrooms. One place to unpack attitudes about diversity in the classroom is to encourage teachers in training to become aware of their own ethnocentrism. One way for teachers to become…

This study focused on the robustness of unidimensional item response theory (UIRT) models in computerized classification testing against violation of the unidimensionality assumption. The study addressed whether UIRT models remain acceptable under various testing conditions and dimensionality strengths. Monte Carlo simulation techniques were used…

Understanding of immunological techniques such as the Enzyme Linked Immuno Sorbent Assay (ELISA) is an important part of instructional units in human health, developmental biology, microbiology, and biotechnology. This paper describes a simple ELISA exercise for undergraduate biology that effectively simulates the technique using a paper model.…

In studies investigating the power of person-fit statistics it is often assumed that the item parameters that are used to calculate the statistics can be estimated in a sample without aberrant persons. However, in practical test applications calibration samples most likely will contain aberrant persons. In the present study, the influence of the…

The zeitgeist for reform in education precipitated a number of changes in assessment. Among these are performance assessments, sometimes linked to "high stakes" accountability decisions. In some instances, the trustworthiness of these decisions is based on variance components and error variances derived through generalizability theory.…

When items are selected during a computerized adaptive test (CAT) solely with regard to their measurement properties, it is commonly found that certain items are administered to nearly every examinee, and that a small number of the available items will account for a large proportion of the item administrations. This presents a clear security risk…

The extent to which properties of the ability scale and the form of the latent trait distribution influence the estimated item parameters of item response theory (IRT) was investigated using real and simulated data. Simulated data included 5,000 ability values randomly drawn from the standard normal distribution. Real data included the results for…

Suitable for secondary school students, the workbook provides flowcharting activities to help students understand the logical steps used in problem solving. Before applying the flowcharting procedures to mathematical problems, students are first introduced to familiar non-mathematical problems such as sharpening a pencil or eating peanuts. Section…

The effects of high versus low teacher control strategies on student objectives in a quasi-simulation University Career Game were studied. Results showed that high-control subjects made significantly more goal choices for educational efficiency, while low-control subjects made significantly more choices favoring personal and social growth.…

The ways in which role playing and simulation can assist students to clarify their values and to develop more adequate values is described. (DE)

Discussion of political science games and their use at the college level is intended to present a case for the feasibility and desirability to expand the role of simulation in Soviet studies. (Author/ND)

Explains the educational value of computer simulations in general and provides specific areas of computer application in teaching of chemistry, biology, and physics. Explains the application of instructional materials developed in the Chelsea Science Simulation Project. (GS)

This study examined several explicit and implicit assertions in Rosenhan's "On Being Sane in Insane Places" (AA 521 951), as well as methodological and logical shortcomings and interpretations contrary to those presented. (Author/RK)
