The article discusses how the increasing specificity of the design of a person's work in business will permit more effective educational preparation. (Author)

Langmuir's model is studied for the situation where epsilon is independently and identically normally distributed. The "Y/x" versus "Y" plot had a 90% mid-range that did not contain the true curve in a vast portion of the range of "x". The "1/Y" versus "1/chi" plot had undefined expected values,…

Computers can be used in a variety of ways in the social studies classroom: (1) as a productivity tool to relieve the teacher of the many bookkeeping tasks and allow for more time to be spent on instructional tasks; (2) in business applications such as data base files, electronic spreadsheets, word processing, computer graphics, and to store large…

The use of an electoral college simulation model by college students is described. At least 16 students should participate to represent four geographical regions: the Northeast, the South, the Midwest, and the West. The electoral college simulation is most relevant in courses on American politics, the United States presidency, and elections.…

Noting that advertising students in smaller colleges have little opportunity for exposure to major advertising companies as role models, the advertising class at a North Dakota university was given the opportunity to design an actual magazine layout to promote the university's Aerospace Science Center. The winning ad, as judged by the dean of the…

Designed to simulate a Senate committee hearing on software copyright laws, this role-playing game exposes students to a wide variety of viewpoints about software copying, including piracy. The game is structured to bring out as many points of view as possible; the goal of the simulation is exposure to these various points, not the final committee…

Concern has been expressed over the item response theory (IRT) assumption that a person's ability can be estimated in a unidimensional latent space. To examine whether or not the response to an item requires only a single latent ability, unidimensional ability estimates were compared for data generated from the multidimensional item response…

Team projects are commonly used for assignments in advertising coursework, since they parallel the team effort which ad professionals experience as a customary part of their work experience. However, while offering many benefits, this teaching format often means reduced visibility and/or responsibility for the individual. In creating this agency…

This chapter considers the history of instructional development (ID) in the military, with particular emphasis on the U.S. Navy. The ID process used at the Navy's Instructional Program Development Centers is presented, including the process for simulator development. An in-depth analysis of the problems encountered with educational technology…

The concept of a qualitative model provides a unifying perspective for understanding how expert systems differ from conventional programs. Knowledge bases contain qualitative models of systems in the world, that is, primarily non-numeric descriptions that provide a basis for explaining and predicting behavior and formulating action plans. The…

The report describes activities and results of the second year of the Special Education Planning Model (SEPM), designed to help planners and policymakers estimate special education program needs and costs. SEPM uses a computer simulation based on users' assumptions and priorities in such areas as incidence rates, handicapping conditions to be…

The distribution of a certain item response theory (IRT) based person fit index to identify systematic types of aberrance is discussed. For the Rasch model, it is proved that: (1) the joint distribution of subtest-residuals (the components of the index) is asymptotically multivariate normal; and (2) the distribution of the index is asymptotically…

Methods and indices based on item response theory (IRT) for detecting and diagnosing aberrant response patterns are reviewed. These indices are divided into three groups: (1) residuals-based; (2) likelihood-based; and (3) ratio of covariances-based (extended cautions). For each index, the determination of its sampling distribution as well as its…

This paper recommends the use of a computer simulation about trade and tariff negotiations to reinforce and apply principles learned in undergraduate international trade courses and to provide students with an opportunity to use the advanced features of Symphony, a computer spreadsheet. This simulation is a game in which both the class and…

Based on a workshop on vision research issues in flight-training simulators held in June 1980, this report focuses on approaches for the conduct of research on what visual information is needed for simulation and how it can best be presented. An introduction gives an overview of the workshop and describes the contents of the report. Section 1…
