A study of 696 undergraduates at the University of Northern Colorado was undertaken to determine the effects of computerized unit test item feedback on final examination scores. The study, which employed the PHOENIX computer managed instruction system, included students at all undergraduate levels enrolled in an Oceanography course. To determine…

In January 1985, Employment and Immigration Canada funded a pilot project in New Brunswick for the development and testing of an Interprovincial Computerized Examination Management (ICEM) System. The resulting system is comprised of a dual interprovincial and provincial item bank facility, a software component offering the option of computerized…

The difficulty of test items administered by paper and pencil were compared with the difficulty of the same items administered by computer. The study was conducted to determine if an interaction exists between mode of test administration and ability. An arithmetic reasoning test was constructed for this study. All examinees had taken the Armed…

The purpose of this paper is to report results on the development of a new computer-assisted methodology for creating parallel test forms using the item response theory (IRT) information function. Recently, several researchers have approached test construction from a mathematical programming perspective. However, these procedures require…

The purpose of this study is to determine an efficient way to reduce the bias in estimates of the Rasch model parameters due to aberrant response patterns. First, the benefits of using one- or two-sided goodness-of-fit tests of patterns with the model are discussed. Then, the consequences of removing non-fitting patterns from Rasch model data are…

A heuristic for solving large-scale zero-one programming problems is provided. The heuristic is based on the modifications made by H. Crowder et al. (1983) to the standard branch-and-bound strategy. First, the initialization is modified. The modification is only useful if the objective function values for the continuous and the zero-one…

Two experiments using the same design and subjects drawn from the same populations tested two accounts of schema-directed text processing, the selective attention hypothesis that suggests readers identify text elements as important or unimportant on the basis of an engaged, operative, or subsuming schema; and the slot-filling hypothesis that…

The videodisc, audiodisc, overlapping instruction, mapping, adaptive testing strategies, intricate instructional branching, and complex media selection models are common expectations for quality courseware today. A two team development structure, consisting of an instructional development team and a test development team, is proposed. This paper…

In defense of retaining the "latent trait theory" term, instead of replacing it with "item response theory" as some recent research would have it, the following objectives are outlined: (1) investigation of theory and method for estimating the operating characteristics of discrete item responses using a minimum number of…

This paper argues that the most important role the intelligent videodisc can fulfill is to provide a mechanism for effectively integrating testing and instruction. This integration will produce at least four important benefits: (1) increased learning by the student, (2) more interesting instructional materials, (3) gains in the efficiency of…

This project evaluated a Course Management System (CMS), which was developed at the University of Illinois and implemented on the PLATO IV instructional system during two semesters of an introductory level economics course. The CMS was designed to integrate books, computer testing, and personnel utilization in applying instructional and computer…

The practice of not sharing tests results with clients may soon be in conflict with the Ethical Standards for Psychologist (sic). Studies using self-validation of feedback information to study feedback parameters have shown that the form of feedback is less important than the content. To investigate direct feedback of test results by computer, the…

This study explored the utility, from a psychometric and cost effectiveness standpoint, of a computerized adaptive measurement system in an Air Force technical training environment. The phase 1 effort was designed to take the study to the point of producing an operational system ready to actually test technical training students adaptively. A…

A series of four vocabulary norming tests was used to develop a large, homogeneous pool of vocabulary test items for use in computer-administered adaptive testing research. Five hundred seventy-five unique vocabulary knowledge items were divided among the four norming tests, and administered to separate groups of college undergraduates. Norming…

A two-stage adaptive test and a conventional peaked test were constructed and administered on a time-shared computer system to students in undergraduate psychology courses. (The two-stage adaptive test consisted of a routing test followed by one of a series of measurement tests.) Comparison of the score distributions showed that the two-stage test…
