In 1990 a routine study confirming the accuracy of the Rasch model in predicting item difficulties led to an in-depth analysis of the impact of guessing on the Rasch model when used with multiple-choice items. This paper reviews the highlights of that research. Seventeen linked vocabulary tests of 110 items were each administered to groups of 400…

When examinees are allowed to review responses on an adaptive test, can they "cheat" the adaptive algorithm in order to take an easier test and improve their performance? Theoretically, deliberately answering items incorrectly will lower the examinee ability estimate and easy test items will be administered. If review is then allowed,…

When test-takers are offered a choice of essay questions, some questions may be harder than others. If the test includes a common portion taken by all test-takers, an adjustment to the scores is possible. Previously proposed adjustment procedures disregard the test-makers' efforts to create questions of equal difficulty; these procedures tend to…

Although the use of hypertext systems for learning complex knowledge has been attracting recent attention, there have been few discussions in the hypertext literature on issues related to the cognitive prerequisites for learning conceptually demanding material. A study was conducted to investigate a theory-based hypertext learning environment that…

The Job Satisfaction Survey (JSS) (P. Spector, 1985 and 1992) is a 36-item survey instrument designed to measure 9 aspects of job satisfaction, including: (1) pay; (2) promotion; (3) supervision; (4) benefits; (5) contingent rewards; (6) operating procedures; (7) co-workers; (8) nature of work; and (9) communication. In addition to measuring the…

This digest discusses the advantages and disadvantages of using item banks, and it provides useful information for those who are considering implementing an item banking project in their school districts. The primary advantage of item banking is in test development. Using an item response theory method, such as the Rasch model, items from multiple…

Trivial Pursuit is a fascinating and popular game most students are familiar with in English. Most are also eager to play it in a foreign language, with the result that inhibitions about speaking are reduced or eliminated and many structures are used. The game is available in German, French, Italian, and Spanish. Some questions about…

A unit on animals was taught to 64 preschool children (44 in an experimental group and 20 in a control group). Children in the experimental group were taught nine major concepts over four levels of abstraction (designated as superordinate, intermediate, subordinate, or particular levels). Each concept was presented by means of an advance organizer…

The strategy variables investigated were: 1) sequence, a presentation of instances according to a defined relationship of the stimuli--organized versus random; and 2) analytical explanation, a verbal statement presented with each instance which analyzed the presence or absence of the critical attributes. Concept learning implications were…

The simplified documents produced by the British and Rhodesian governments to explain the settlement proposals to Africans are compared in terms of syntactic complexity and lexical choice, and in terms of the audience to which the documents are addressed. (Author/RM)

It is a widely held belief that an anchor test used in equating should be a miniature version (or "minitest") of the tests to be equated; that is, the anchor test should be proportionally representative of the two tests in content and statistical characteristics. This paper examines the scientific foundation of this belief, especially…

Social facilitation can be defined as the effect of an audience or coactors on performance. Research on social facilitation effects has produced some contradictory and confusing findings. Some studies have found that the presence of others enhances performance; other studies have found that the presence of an audience or coactors impairs…

Cognitive-based approaches to social and personality psychology have studied the structure of trait constructs in memory. The bipolar view of traits suggests that the activation of a trait construct such as "hostile" should be associated with the simultaneous activation of its semantic opposite "kind." The unipolar view, in…

A key element in a research paper writing assignment modified for students of English as a second language to assure their success is teacher control over most of the process. A chronological plan for action for the micro research project includes these steps: creating an awareness of current events and controversial issues, practicing necessary…

Investigated were the role of mental imagery in children's logical reasoning and individual differences in children's use of imagery while reasoning. Fifth grade students assessed as being high imagers (HIS) and low imagers (LIS) completed conditional syllogisms of various kinds and were asked, after each of their responses, whether an image had…
