The authors studied the testing pattern grades in four e-campus courses at Troy University with 76 graduate students. In their research, the authors found significant differences in average test grade scores between tests taken electronically without a proctor as compared to those administered using a live or a remote proctor overall. To control…

We propose an extension of the Teaching Machine project, called Quiz Generator, that allows instructors to produce assessment quizzes in the field of algorithm and data structures quite easily. This extension makes use of visualization techniques and is based on new features of the Teaching Machine that allow third-party visualizers to be added as…

In cognitive diagnosis a Q-matrix (Tatsuoka, 1983, 1990), which is an incidence matrix that defines the relationships between test items and constructs of interest, has great impact on the nature of performance feedback that can be provided to score users. The purpose of the present study was to identify meaningful skill coding categories that…

A desirable characteristic for an e-learning system is to provide the learner the most appropriate information based on his requirements and preferences. This can be achieved by capturing and utilizing the learner model. Learner models can be extracted based on personality factors like learning styles, behavioral factors like user's browsing…

According to the Quality Assurance Agency, "Assessment describes any processes that appraise an individual's knowledge, understanding, abilities or skills", and is inextricably linked to a course or programme's intended learning outcomes. It also has a fundamental effect on students' learning where it serves a variety of purposes including…

The study examined differences in the distribution of spectral energy among four types of infant vocalizations via computerized spectral analyses. The mean spectral energy (MSE) of "pain induced" cries was significantly higher than those of "fussy" and "hungry" cries, and the MSE of all three cries was higher than…

Provides an overview of the current status of microcomputer-based testing, reviews several testing applications available in microcomputer format, and offers ideas on future developments. (Author)

The expansion of computer technology has created many possiblities for computer applications in the area of psychological testing and assessment. The ways that computers can be used in psychometric assessment, the benefits of such use, and problems that may be encountered with these uses are discussed. (Author/BL)

This study compared several item exposure control procedures for computerized adaptive test (CAT) systems based on a three-parameter logistic testlet response theory model (X. Wang, E. Bradlow, and H. Wainer, 2002) and G. Masters' (1982) partial credit model using real data from the Verbal Reasoning section of the Medical College Admission Test.…

Computer-based testing places great burdens on all involved parties to ensure test security. A task analysis of test site security might identify the areas of protecting the test, protecting the data, and protecting the environment as essential issues in test security. Protecting the test involves transmission of the examinations, identifying the…

Presents an attempt at simplifying test-making procedures through use of a computer. The advantages of the system over conventional evaluation methods are discussed and an outline of its capabilities and limitations is provided. (BD)

Combined the methods of alpha-stratified adaptive testing and constrained adaptive testing with shadow tests. Outlines the advantages of this approach in reducing overexposure and underexposure of items in an item pool and illustrates these advantages with an example from the Law School Admission Test. (SLD)

Compared the properties of five methods of item exposure control in the context of estimating examinees' abilities in a computerized adaptive testing situation. Findings show advantages to the Stocking and Lewis conditional multinomial procedure (M. Stocking and C. Lewis, 1995) and, to a lesser degree, the Davy and Parshall method (T. Davey and C.…

Conducted a meta-analysis to determine the extent to which the computer administration of a measure influences socially desirable responding. Discusses implications of the findings about impression management in terms of how they contribute to the explication of the construct of social desirability and cross-mode equivalence. (Author/SLD)

Evaluated three strategies for assigning examinees to grading categories in computerized adaptive testing. The expected a posteriori-based method had more correct classifications in the middle range of grade levels and more errors for the extremes than the golden section search grading test and the Z-score grading test.
