The purpose of this study was to determine whether it is both possible and cost-effective to revise middle-difficulty Graduate Record Examinations (GRE) discrete items in order to produce items of higher or lower difficulty. The basic procedure was to select items of a given difficulty and, by revising the distractors, make them easier or more…

The possibility exists that some people might be at a disadvantage in registering their responses to a computerized test if mouse manipulation were complicated. This would be of particular concern if some groups were differentially affected by the complexity of manipulation. This study analyzed data from a pilot test conducted in 1991 for the…

Two-stage and multistage test designs provide a way of roughly adapting item difficulty to test-taker ability. All test takers take a parallel stage-one test, and, based on their scores, they are routed to tests of different difficulty levels in subsequent stages. These designs provide some of the benefits of standard computerized adaptive testing…

The first of two studies reported examined the factors that predict differences in item responses for black and white matched examinees to analogies on the Graduate Record Examinations (GRE). Data were taken from 13 forms of the GRE Verbal Test, with a median sample size of 21,000 whites and a median sample size of 1,400 blacks for the purpose of…

The guide contains original and innovative ways to use literature in the second language classroom. The lesson ideas, contributed by teachers, are intended for varied age levels, from young children to graduate students, and come from teachers in all parts of the world. The ideas are divided into four chapters: "Prose"; "Poetry"; "Drama"; and…

A discussion of the relationship of vocabulary to reading comprehension focuses on the instruction of difficult vocabulary to learners of English as a Second Language. The historical background of vocabulary instruction is chronicled and the importance of reading and vocabulary learning to each other is examined. Various kinds of difficult…

Academic records of first year students enrolled in Introductory Chemistry at the University of Guelph, Canada, were used to develop a method to examine the effects of individual courses on freshman academic performance. At the center of the technique is a new test statistic useful in creating individual course profiles. Because grade point…

This Monte Carlo study examined strategies for forming the matching variable for the Mantel-Haenszel (MH) differential item functioning (DIF) procedure. Data were generated using a three-parameter logistic item response theory model, with common guessing parameters. The number of subjects and test length were manipulated, as were the difficulty,…

Ease of language processing varies with the nature of the language involved. Ordinary spoken language is the easiest kind to produce and understand, while writing is a relatively new development. On thoughtful inspection, the readability of writing has shown itself to be a complex topic requiring insights from many academic disciplines and…

The concept of comprehensible input in second language learning is applied to the teaching of English as a Second Language. Techniques for teacher adaptation of materials and classroom presentation are outlined. The first step is assembly of topic-appropriate pictures and the production of simple third-person statements to accompany them. Leisure…

In an effort to improve the ways in which words are learned, the Johnson O'Connor Research Foundation (JOCRF) is attempting to determine the difficulty level of all non-technical words in the English language. This item banking project entails: (1) identifying words that should be calibrated; (2) writing a test item for each word; (3) testing the…

A study was conducted to determine whether there was any match between student perception of reading ease and the readability of three main line, first-year college composition texts (Daugherty; Kinneavy, McCleary, and Nakadate; Lauer, Montague, Lunsford, and Emig) as determined by five commonly used readability formulas. Two chapters (on…

Factors affecting a lower-bound estimate of internal consistency reliability, Cronbach's coefficient alpha, are explored. Theoretically, coefficient alpha is an estimate of the correlation between two tests drawn at random from a pool of items like the items in the test under consideration. As a practical matter, coefficient alpha can be an index…

It is important to introduce and facilitate oral activities in the second language classroom with enthusiasm in a climate of mutual support and cooperation. Students should understand that mistakes are inevitable but not fatal, and that each attempt will build greater ease and confidence in using the language for communication. Oral proficiency…

The purposes of this study were threefold: (1) to identify school principals' perceptions of their occupational responsibilities and the academic preparation needed for those responsibilities; (2) to determine significant relationships between perceptions of preparation and perceptions of difficulty; and (3) to identify significant differences…
