The reasons for recent endeavors to evaluate item bias are discussed, and item bias is defined. Some of the literature regarding the most promising methods of detecting item bias is reviewed. Three classes of methods for detecting item bias are discussed using concrete examples and illustrations. These methods are: (1) latent trait; (2)…

Developmental differences in two components of allocation of study time were examined: (1) allocating more time to more difficult material (that is, differential allocation) and (2) allocating sufficient time to meet the recall goal (sufficient allocation). In order to make the task simple enough for young children, "easy" and…

This study compared item difficulty and item discrimination indices for parallel multiple-choice items in three content areas: measurement concepts, statistical terminology, and synonyms. The statistics and measurement items were administered in classes where graduate students taking the test were studying the content. Vocabulary items represented…

A lesson in the use of pronunciation keys provided in English dictionaries, which is designed for adult foreign students, includes notes to the teacher concerning preliminary activities, discussion of the approach, a description of the lesson sequence, and a lesson designed for the student's use. The three-segment lesson, designed for second- and…

The research reported in this paper is concerned with the ability of students of English as a second language (ESL) to apply cognitive skills in reading. The paper focuses on: (1) a validation study of an experimental test designed to measure Piagetian concrete operations in reading and (2) the effects of the paragraph types (additive or…

This computer program, written in BASIC, performs three different calculations of test reliability: (1) the Kuder-Richardson method; (2); the "common split-half" method; and (3) the Rulon-Guttman split-half method. The program reads sequential access data files for microcomputers that have been set up by statistical packages such as…

Examined were effects of advance organizer (AO) instruction on acquisition of conservation concepts in 3- and 4-year-olds. Participants were 28 children who were equally divided into experimental and control groups, pretested, and found to be nonconservers. A sequence of two AO lessons and related learning activities was presented to the…

Outside the core grammar, the set of "peripheral" or marked properties of a language include exceptions or relaxations of the settings of core grammar and the idiosyncratic features of the language governed by particular lexical items. The core/peripheral distinction has direct implications for grammatical development in children. The…

In addition to using films in the German classroom to introduce students to German culture and history, it is important to show and study the film as film. This procedure emphasizes the importance of the film as a part of creative arts in Germany and demands student participation in observation and discussion. Many German silent films are…

Real test data of unknown structure were analyzed using both a unidimensional and a multidimensional latent trait model in an attempt to determine the underlying components of the test. The models used were the three-parameter logistic model and a multidimensional extension of the two-parameter logistic model. The basic design for the analysis of…

A standard method for exploring item bias is the intergroup comparison of item difficulties. This paper describes a refinement and generalization of this technique. In contrast to prior approaches, the proposed method deletes outlying items from the formulation of a criterion for identifying items as deviant. It also extends the mathematical…

Learning to communicate is important for today's foreign language student, and it is important to provide meaningful communicative experiences in writing as well as speaking the language. A letter exchange between peers can provide a meaningful and exciting writing experience for lower-level students. While not entirely without problems, arranging…

In most item response theory models a particular mathematical form is assumed for all item characteristic curves, e.g., a logistic function. It could be desirable, however, to estimate the shape of the item characteristic curves without prior restrictive assumptions about its mathematical form. We have developed a practical method of estimating…

A scale was developed and tested to measure metaphoric complexity in order to aid teachers in the selection and sequencing of young adult (YA) novels in the English curriculum. The development and testing of the scale involved two stages: (1) the development of a questionnaire to determine if differences in the metaphoric complexity of examples…

This study assessed the effect of six weeks of sentence-combining activities on the syntactic maturity of first-year university students. The Syntactic Maturity Test (SMT) and a free writing exercise were used as pre/post instruments to determine words-per-T-unit and words-per-clause ratios. Significant results favoring the experimental group were…
