A tailored testing model employing the beta distribution, whose mean equals the difficulty of an item and whose variance is approximately equal to the sampling variance of the item difficulty, and employing conditional item difficulties, is proposed. The model provides a procedure by which a minimum number of items of a test, consisting of a set…

The initial development of a testlet-based algebra test was previously reported (Wainer and Lewis, 1990). This account provides the details of this excursion into the use of hierarchical testlets and validity-based scoring. A pretest of two 15-item hierarchical testlets was carried out in which examinees' performance on a 4-item subset of each…

This final report describes the outcomes of Project MAPS (Monitoring Authentic Problem Solving), a project that developed multimedia computer-managed assessment environments to overcome the barriers educators face in using problem-solving performance assessment (PSPA) with students with disabilities. MAPS software was developed for 6 alternate…

Discusses summative and formative evaluation methods used and problems encountered in the study of LOGICLANDIA, a courseware package for the teaching and learning of predicate logic in Italian secondary schools. The evaluation process had three phases: subjective, in-house prototypes, and field testing. Results produced revisions in courseware…

Three study cohorts involving 199 gifted fifth graders, 190 gifted sixth graders, and 683 typical sixth graders were used to construct, validate, and pilot a computerized adaptive math test for placing fifth graders in a middle school mathematics gifted program. Results suggest the adaptive test has potential for talent identification. (Author/CR)

Analysis of patterns in time (APT) is presented as a method for gathering information about observable phenomena so that probabilities of temporal patterns of events can be estimated empirically. APT is illustrated through a classroom study of 25 mentally handicapped students and in a study of 2 computer-based tests. (SLD)

Discussion of computerized adaptive testing focuses on a study of graduate students at Indiana University at Bloomington that examined three kinds of computerized adaptive testing procedures to determine their psychological impact and how they may affect test performance. Previous research is reviewed, and further research is suggested. (28…

Describes the workings of computerized adaptive testing (CAT). Focuses on the key concept of information and then discusses two important components of a CAT system: the calibrated item bank and the testing algorithm. Describes a CAT that was designed for making placement decisions on the basis of two typical test administrations and notes the…

The education of students is fundamental to shaping a preferred provincial, national and global future. It is also essential in maintaining Alberta's standard of living and ensuring its global competitiveness. The education system must simultaneously prepare the citizens of tomorrow while equipping the students with the knowledge and skills they…

Four researchers at the Educational Testing Service describe what they consider some of the most vexing research problems they face. While these problems are not completely statistical, they all have major statistical components. Following the introduction (section 1), in section 2, "Problems with the Simultaneous Estimation of Many True…

In the summer of 1996, the U.S. Armed Services will implement the computerized adaptive testing version of the Armed Services Vocational Aptitude Battery (CAT-ASVAB). When conversion is completed at the 65 targeted military entrance processing stations, about half the applicants will take this test version. This paper describes the efforts that…

The purpose of the study was to investigate the effects of test motivation on estimated ability, test anxiety, and attitudes toward computerized adaptive testing (CAT). Korean college students (n=208) were given the Math Aptitude Test, Math Self-Concept Scale, Math Test Anxiety Scale, Computer Competence Instrument, Computer Anxiety Scale, and…

Educational measurement is undergoing a revolution due to the rapid dissemination of information-processing technology. The recent growth in computing resources and their widespread dissemination in daily life have brought about irreversible changes in educational measurement. Recent developments in computerized measurement are summarized by…

Results of administering a computerized adaptive version of the Grammar, Spelling, and Punctuation Test (GSP) to students in the College of Communication at the University of Texas, Austin were studied. The computerized adaptive version (CAT) was administered for the first time in June 1992 to 35 prospective students who participated in the…

This report summarizes the results of research designed to study the psychometric and technological feasibility of adaptive testing to assess spatial ability. Data was collected from high school students on two types of spatial items: three-dimensional cubes and hidden figure items. The analysis of the three-dimensional cubes focused on the fit of…
