The present paper represents a demonstration of how LISREL V can be used to investigate scale invariance (1) across time (its relationship to test-retest reliability), and (2) across groups. Five criteria were established to test scale invariance across time and four criteria were established to test scale invariance across groups. Using the…

The cognitive processes in a widely used, non-verbal test of analytic intelligence--the Raven Progressive Matrices Test (J. C. Raven, 1962)--were analyzed. The analysis determined which processes distinguished between higher-scoring and lower-scoring subjects and which processes were common to all subjects and all items on the test. The analysis…

A nominal response model-based computerized adaptive testing procedure (nominal CAT) was implemented using simulated data. Ability estimates from the nominal CAT were compared to those from a CAT based upon the three-parameter logistic model (3PL CAT). Furthermore, estimates from both CAT procedures were compared with the known true abilities used…

This study was conducted to investigate whether increased levels of state anxiety are associated with microcomputers. Participants included 116 undergraduate and graduate education and library science students with an age range of 20 to 55. The State-Trait Anxiety Inventory, Form Y, was administered to a control group (N=58) and an experimental…

Subjects for an investigation of the effects of training with a computer and past computer experience on the computerized aptitude test performance of college students were 92 undergraduates at the University of North Carolina at Charlotte, who participated in a test study utilizing six Apple II+ microcomputers. The study was conducted to…

The present monte carlo simulation study was designed to examine the effects of multidimensionality during the administration of computerized adaptive testing (CAT). It was assumed that multidimensionality existed in the individuals to whom test items were being administered, i.e., that the correct or incorrect responses given by an individual…

Major efforts of this project fall into four categories: (1) investigations were performed on the relationship between the dimensionality of a dataset and its underlying cognitive processes; (2) two approaches for diagnosing erroneous rules of operation were developed (an "error vector" system for constructing error diagnostic programs…

In the answer-until-correct mode of multiple-choice testing, respondents are directed to continue choosing among the alternatives to each item until they find the correct response. There is no consensus as to how to convert the resulting pattern of responses into a measure because of two conflicting models of item response behavior. The first…

The graphics and animation capabilities of computers offer a new dimension in science testing. Instead of presenting verbal situations or questions with accompanying pictures, computers can present simulated actions and events that are the focus of science questions. The purpose of this project was to develop a valid and reliable computer-based…

This paper has shown the advantages of tailored testing over traditional methods, the need for latent trait theory in the application of tailored testing, and some of the results available to show the quality of estimates obtained by tailored testing procedures. Since the tailored testing procedures overcome many of the problems with traditional…

The computer can assist test construction in the following four ways: (1) storage or banking of test items; (2) banking of item attributes; (3) test construction; and (4) test printing. Automated Item Banking (AIB) is a computerized item storage and test construction system which illustrates these capabilities. It was developed, implemented, and…

The cognitive determinants of number series completion performance were studied by presenting a systematic set of problems to adults and to children of high and average intelligence, grades 4 and 5. Pearson correlations between these problems and the number series on the Cognitive Abilities Test were .51, .78 and .43 for the average intelligence,…

By means of computer simulation of test responses, the reliability of item analysis data and the accuracy of equating were examined for hypothetical samples of 250, 500, 1000, and 2000 subjects for two tests with 20 equating items plus 60 additional items on the same scale. Birnbaum's three-parameter logistic model was used for the simulation. The…

This paper describes two procedures for making binary classification decisions using tailored testing: the sequential probability ratio test (SPRT) and a Bayesian decision procedure. The first procedure described, the SPRT, was developed by Wald for quality control work. It has not been widely applied for testing applications because the…

This pamphlet contains five reports on different aspects of the Oakleaf Small Computer Project. The major objective of the project was to individualize elementary mathematics instruction by using a fully-integrated system of computer-assisted instruction, evaluation, and class management. The curriculum used was based on IPI Mathematics. The…
