A two-stage testing strategy is one method of adapting the difficulty of a test to an individual's ability level in an effort to achieve more precise measurement. A routing test provides an initial estimate of ability level, and a second-stage measurement test then evaluates the examinee further. The measurement accuracy and efficiency of item…

Hypermedia applications have presented information through a variety of visual media, but the aural channel for information delivery has not been well developed. To reduce the likelihood of overloading the visual channel of communication in a program that presents a great deal of information through graphic illustration and animation, the…

This paper describes an activity developed at the University of Nebraska to familiarize prospective teachers with the process of developing Individualized Education Programs (IEPs) for students with disabilities. The activity, titled "Experiencing the Change Process: Writing a Personalized IEP," acquaints students with the major IEP…

This study used Markov chain matrices to simulate the effect of varying degrees of change in student characteristics on retention and graduation rates. Data were applied to a 1-year enrollment transition matrix that tracks how students of each class level progress into the same or higher class levels, to a completed degree, or to non-returning…

This paper discusses the development of computer-based business simulations designed to prepare high school students for entry-level jobs in business, and explores the implementation of feedback mechanisms in simulations. Reasons why simulations are an appropriate type of media for this application, the nature of feedback, and research on feedback…

This paper discusses four areas in the psychology literature that have important implications for the instructional design of microcomputer-based simulations. The first one examined is cognitive structures, and the following suggestions for instructional design are offered: simulations should be appropriate for students' level of understanding;…

This paper discusses two software packages used in kinematics courses at Purdue University, Calumet (Indiana) and some algorithms written by students for cam design. The first software package, 4BAR, requires the user to define the particular four bar linkage in terms of lengths of the individual links and the angle and distance to the coupler…

A practical guide for language teachers illustrates the different ways in which cameras can be employed in language work, with suggestions and advice taken from current experience. Teachers can be involved by making their own language training videotapes and focusing on an area of language, literature, or thematic interest directly applicable to…

This theme issue covers "High School Programming" and approaches to meeting the needs of gifted high school students in Texas. The first article is "Thematic Interdisciplinary Curricula for Secondary Gifted Students in English and Social Studies" (Joel E. McIntosh and April W. Meacham). This approach is contrasted with the…

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…
