This report discusses advances in computer-based technologies that can be used for teaching limited English proficient (LEP) minority students. These technologies offer multisensory delivery, increased self-expression and active student learning, cooperative learning, communication skill practice, multicultural education, and enhanced motivation.…

This study investigated the characteristics of Computer-based Case Simulations (CCS) that may be associated with case difficulty. Difficulty was defined as the average rating by physicians of examinee performance on a nine-point scale or the passing rate on the cases. Two data sets were used, one from an administration of 18 cases to 201 medical…

One important and promising application of item response theory (IRT) is computerized adaptive testing (CAT). The implementation of a nominal response model-based CAT (NRCAT) was studied. Item pool characteristics for the NRCAT as well as the comparative performance of the NRCAT and a CAT based on the three-parameter logistic (3PL) model were…

Role-playing and simulation are recommended as effective methods of introducing business content into Russian language courses. The advantages of role-playing, which make it a flexible and effective tool throughout the foreign language curriculum, are discussed. Use of role-play in introductory courses is addressed, but focus is primarily on use…

This document on contingent student assistance repayment plans in Ontario universities contains a paper on policy options for repayment plans and the manual for a simulation model for testing policy options. The policy options paper begins by describing the contingent repayment concept in which the test for receiving a public subsidy is shifted…

The following seven statistical procedures are compared in terms of the ability to recover a unidimensional latent trait from Likert-type data: (1) factor analysis based on Pearson correlations (FA-PR); (2) factor analysis based on polychoric correlations (FA-PL); (3) the graded response model in item response theory (IRT-GRM); (4) internal…

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…
