Hierarchical Bayes procedures were compared for estimating item and ability parameters in item response theory. Simulated data sets from the two-parameter logistic model were analyzed using three different hierarchical Bayes procedures: (1) the joint Bayesian with known hyperparameters (JB1); (2) the joint Bayesian with information hyperpriors…

This paper focuses upon the research and development (R&D) process associated with developing automated feedback materials for the SIMulation NETworking (SIMNET) training system. This R&D process involved a partnership among instructional developers, practitioners, and researchers. Users' input has been utilized to help: (1) design the…

The differences between multiple-choice, simulated, and concurrent tests of software-skills proficiency are discussed. For three basic human-resource functions, the advantages of concurrent tests (i.e., those that use the actual application software) include true performance-based assessment, unconstrained response alternatives, and increased job…

Three methods of estimating test score distributions that may improve on using the observed frequencies (OBFs) as estimates of a population test score distribution are considered: the kernel method (KM); the polynomial method (PM); and the four-parameter beta binomial method (FPBBM). The assumption each method makes about the smoothness of the…

Part 1 of this two-part document reviews efforts to develop computer-based case management simulations for use in rehabilitation education. It examines both single-case management simulations which concentrate on clinical problem-solving skills required to serve a single client and multiple-case management simulations which focus on skills…

Hypothesis generation has been proven to be a crucial phase in the clinical inquiry. The current instruments for measuring clinical problem-solving skills, however, are unable to differentially assess the hypothesis generating ability. For assessing this particular capability a new test is described. It is based upon exposing the examinee to an…

The present study investigated whether infants of mothers who were depressed postpartum would behave like infants of non-depressed mothers who simulated depression. A total of 24 mothers and their 3-month-old infants were videotaped during face-to-face interactions. All mothers were given the Beck Depression Inventory (BDI) and the State-Trait…

The nine articles in this collection were selected because they represent concerns central to computer science, emphasize topics of particular interest to mathematicians, and underscore the wide range of areas deeply and continually affected by computer science. The contents consist of: "Introduction" (S. V. Pollack), "The…

A latent trait model is described that is appropriate for use with tests that measure more than one dimension, and its application to both real and simulated test data is demonstrated. Procedures for estimating the parameters of the model are presented. The research objectives are to determine whether the two-parameter logistic model more…

This environmental teaching guide is designed to help Illinois teachers promote wise land-use planning at the secondary level. Program objectives, background information, activities and games for use in and outside of the classroom, a simulated problem-solving exercise, resource lists, and a test with answers are included.

This study aims to report the effort on teaching vector algebra using free open source software (FOSS). Recent studies showed that students have difficulties in learning basic physics concepts. Constructivist learning theories suggest the use of visual and hands-on activities in learning. We will report on the software used for this purpose. The…

This paper reports the current findings in literature on the impact of instructional technologies on teaching and learning environments pertaining higher education institutions. This study investigates the instructional design strategies in terms of (1) the scope of change in design strategies as a result of current school reform in the United…

This paper argues that the use of unrestricted natural language (UNL) interaction is essential in computer-assisted instruction aimed at teaching clinical decision making, and in interactive tests that emulate oral examinations. Knowledge about the scope and limitations of computerized UNL interaction gained during the development of the authoring…

Implan (Impact Analysis for Planning) is a microcomputer-based system for constructing regional economic accounts and input-output tables. It is currently maintained by the U.S. Forest Service at the Fort Collins Computer Center (Colorado) with assistance from the University of Minnesota. It provides software capabilities and a data base for…

The techniques used for teaching college economics have remained relatively unchanged over the past few decades. These techniques do not give the students an opportunity to apply, to develop, or to practice the economic theory they read about and hear in lectures. They tend to reinforce student assumptions about the subject's "givenness"…
