The objective of this study was to examine the nature of preservice teachers' evaluations of elementary mathematics problems using the Mathematical Tasks Framework (MTF), a model designed to discriminate among tasks according to their cognitive complexity. We also tested the relationship between mathematics content knowledge and problem length on…

When an examination consists, in whole or in part, of constructed response items, it is a common practice to allow the examinee to choose among a variety of questions. This procedure is usually adopted so that the limited number of items that can be completed in the allotted time does not unfairly affect the examinee. This results in the de facto…

The purpose of this study was to identify differentially functioning items on operational administrations of the Graduate Management Admission Test (GMAT) through the use of the Mantel-Haenszel statistic. Retrospective analyses of data collected over 3 years are reported for black/white and female/male comparisons for the Verbal and Quantitative…

The annotated reading list cites works of fiction and non-fiction felt to be appropriate for learners of English as a Second Language (ESL) or English as a Foreign Language (EFL). Most are suitable for students at the "professional proficiency" level, although some may be read by students at the "limited working proficiency" level, and some are…

Examinee response times from a computerized adaptive test taken by 204 examinees taking a certification examination were analyzed using a hierarchical linear model. Two equations were posed: a within-person model and a between-person model. Variance within persons was eight times greater than variance between persons. Several variables…

Tests in social studies and integrated science given in Saint Vincent, Saint Lucia, Grenada, and Dominica were analyzed by the Organization for Co-operation in Overseas Development (OCOD) Comprehensive Teacher Training Program (CTTP) for discrimination, difficulty, and reliability, as well as other characteristics. There were 767 examinees for the…

This study investigated the characteristics of Computer-based Case Simulations (CCS) that may be associated with case difficulty. Difficulty was defined as the average rating by physicians of examinee performance on a nine-point scale or the passing rate on the cases. Two data sets were used, one from an administration of 18 cases to 201 medical…

When an examination consists in whole or part of constructed response test items, it is common practice to allow the examinee to choose a subset of the constructed response questions from a larger pool. It is sometimes argued that, if choice were not allowed, the limitations on domain coverage forced by the small number of items might unfairly…

A Monte Carlo study was conducted to estimate the small sample standard errors and statistical bias of psychometric statistics commonly used in the analysis of achievement tests. The statistics examined in this research were: (1) the index of item difficulty; (2) the index of item discrimination; (3) the corrected item-total point-biserial…

A study investigated differences in discourse styles that may affect second language listening comprehension. Ten amateur actors performed three speaking tasks: (1) reading aloud a short self-contained narrative; (2) acting out a memorized script; and (3) conversing with the researcher for 20-30 minutes. Excerpts of the recorded tasks in different…

This paper explores the comparability of item calibrations for three types of items: (1) text only; (2) text with photographs; and (3) text plus graphics when items are presented on written tests and computerized adaptive tests. Data are from five different medical technology certification examinations administered nationwide in 1993. The Rasch…

Many writers suggest the use of metaphors in creating hypermedia and multimedia products. However, it is unclear how to choose an appropriate metaphor and how to avoid an inappropriate metaphor that will cause confusion and conceptual difficulties for users. A metaphor compares one thing to another without directly stating the comparison,…

This study investigated continuing motivation for hard and easy tasks and subjects' judgements of selected learner characteristics purported to be related to learning and motivation. The data were collected through subjects' self-reports on a Student School and Work Survey questionnaire. The subjects were approximately 100 males and 100 females…

A study examined eight business Spanish textbooks for cultural content by looking at commonly appearing cultural topics and themes, presentation of cultural information, activities and techniques used to promote cultural understanding, and incorporation of authentic materials. The texts were evenly divided among beginning, intermediate, and…

The final report consists of three studies on aspects of a common theme, that a hearing impaired (HI) person's performance on information processing tasks depends on interactions of that person's cognitive structure and strategies with properties of materials to be processed and task demands. The first study, "Recall of Temporal/Spatial…
