The use of ability variables for grouping students is pervasive in elementary schools. Teachers form these groups judgmentally, taking into account formal (e.g., test) and informal (e.g., personal observation) sources of information. Their judgments of students' abilities are reasonably accurate. Such grouping can be explained as functional on…

Instructors who develop classroom examinations that require students to provide a numerical response to a mathematical problem are often very concerned about the appropriateness of the multiple-choice format. The present study augments previous research relevant to this concern by comparing the difficulty and reliability of multiple-choice and…

This analysis of the National Certifying Examination for Operating Room Technicians revealed that examinee's performance was related to their educational preparation. Utilizing test results from 2,841 candidates, the performance of first time candidates was compared to the performance of graduates of one or two-year programs and of technicians who…

Latent trait theory is used as a basis for a definition of item bias, and an experiment is described in which a test of vocabulary items was not found to be biased when administered to two groups of high school students, one group of 58 black students and the other 168 white students. The experiment for the detection of bias began with separate…

This equating study of the National Board of Medical Examiners Examinations was a combined common persons and common items equating, using the Rasch model. The 1,000-item test was administered to about 3,000 second-year medical students in seven equal-length subtests: anatomy, physiology, biochemistry, pathology, microbiology, pharmacology, and…

Differences among test item writers and among different rules for writing multiple choice items were investigated. Items testing comprehension of a prose passage were varied according to five factors: (1) information density of the passage; (2) item writer; (3) deletion of nouns, as opposed to adjectives, from the sentence in order to construct…

Since grade-appropriate levels of standardized achievement tests must frequently be used in Elementary and Secondary Education Act Title I evaluations, there may be large discrepancies between test difficulty and the achievement level of those being tested, with resultant inaccuracies in the scores. Procedures based on the Rasch scaling model were…

This study is an initial investigation of the effects of grade level, item content and type of probe on children's understanding of communicative ineptness. It was hypothesized that children's recognition and avoidance of inept communications would increase as a function of age and that recognition of ineptness would precede the ability to avoid…

Using informal, objectives-based, or linguistic methods, three elementary school teachers and three experienced item writers developed criterion-referenced pretests-posttests to accompany a prose passage. Item difficulites were tabulated on the responses of 364 elementary students. The informal-subjective method, used by many achievement test…

This study investigated the quantitative and qualitative differences in the responses of children aged four, six, and eight to four kinds of questions; cognitive memory, convergent, divergent, and evaluative. The subjects, 48 boys and girls, were from advantaged homes and had attended, or were attending, nursery school. Each subject was shown a…

The hypotheses that interpersonal learning is more effective than individual learning in nonlinear tasks but that students learn relatively less from their teachers when the teachers have to teach a complex nonlinear rule than when they have to teach a simple linear rule was tested in an experiment following the social judgment theory…

The compositions of sixth, tenth, and twelfth grade students were used to determine whether narrations or arguments of high syntactic complexity were rated higher than narrations or arguments of low syntactic complexity. Selection of the compositions was made in pairs--one of high syntactic complexity and one of low syntactic complexity--each…

TRAINING TASKS WERE PRESENTED UNDER LABORATORY CONDITIONS TO NEWLY INDUCTED ARMY BASIC TRAINEES GROUPED BY ARMED FORCES QUALIFICATION TEST (AFQT) SCORES. THE HIGH GROUP (N=52) RANGED IN SCORE FROM 90 TO 99, THE MIDDLE GROUP (N=30) FROM 45 TO 55, AND THE LOW GROUP (N=61) FROM 10 TO 21. TASKS WERE VARIED IN COMPLEXITY INCLUDING SIMPLE AND CHOICE S-R…

One of 52 theoretical papers on school crime and its relation to poverty, this chapter presents an aesthetic theory of vandalism and reports nine original empirical studies that are relevant to the theory. It is proposed that the act of destroying an object is enjoyable because it is, in effect, an aesthetic experience. The essay is divided into…

Latent trait models may offer considerable potential for the improvement of educational measurement practices, but until recently, they have received only limited attention from measurement specialists. This paper provides a brief introduction to latent trait models, and provides test practitioners with a non-technical introduction to the…
