The two-parameter graded response latent trait model was applied under various conditions to two simulation data sets and to data obtained from a Likert-type attitude scale. The purpose was to investigate the invariance property of the item and person parameter estimates for polychotomously scored data. Correlation and regression analyses, as well…

A study examined the relationship between students' linguistic insecurity (writing apprehension) and writing performance. College students in three remedial and two freshman composition classes were administered a test of linguistic insecurity that included pronunciation items and choices of hypercorrect, colloquial, and nonstandard versions of…

This fifty item multiple choice test was developed by Portland Public Schools, Maine, to assess middle school students' understanding of the concepts presented in the "Responsibility" unit of the "Law in a Free Society" materials published by the California Bar Association. These materials deal with eight concepts for…

Research on the Rasch model of test and item analysis was applied to tests constructed from item banks for reading and mathematics with respect to five practical problems for scaling items and equating test forms. The questions were: (1) Does the Rasch model yield the same scale value regardless of the student sample? (2) How many students are…

The complexity of language of four, five, and six year old children was examined in a psycholinguistic study that attempted to differentiate the characteristics of sentences that were difficult for children to comprehend from those which were easy, and to discover whether children used a subject-verb-object (S-V-O) language strategy to interpret…

One factor that contributes to the difficulty that a reader may encounter when reading a text is the syntactic complexity of the constructions used in the text. Examples of altered text constructions include the transformations of subjects of subordinate clauses, making them either the subjects or the objects of main clauses. When the conditions…

Methods and results relevant to the introduction of item characteristic curve (ICC) models into classroom achievement testing are provided. The overall objective was to compare several common ICC models for item calibration and test equating in a classroom examination system. Parameters for the one-, two- and three-parameter logistic ICC models…

The setting of standards involves subjective value judgments. The inherent arbitrariness of specific standards has been severely criticized by Glass. His antagonists agree that standard setting is a judgmental task but they have pointed out that arbitrariness in the positive sense of serious judgmental decisions is unavoidable. Further, small…

A study was conducted to compare the quality of the item parameter estimates obtained from the ANCILLES and LOGIST estimation procedures using goodness of fit as a criterion. Statistics used to compare the fit included a chi-square statistic and a mean square deviation statistic. Other analyses performed included comparisons of the distributions…

Results from equipercentile, linear, and latent trait equating of the vocabulary and quantitative thinking tests of the Iowa Tests of Educational Development were compared. The study entailed both the equating of forms (of similar difficulty) and the equating of levels (of differing difficulty). The goal was to equate seventh edition tests to…

In most reliability studies, the precision of a reliability estimate varies inversely with the number of examinees (sample size). Thus, to achieve a given level of accuracy, some minimum sample size is required. An approximation for this minimum size may be made if some reasonable assumptions regarding the mean and standard deviation of the test…

In this study, Hull's Drive Theory was applied to a test of the effects of general anxiety and situational stress upon speakers' lexical diversity, speaking rate, speaking time, and evaluations made of the speakers' ability. Recordings of speeches made by 122 individuals were rated by three judges on scales measuring central idea and analysis,…

The phenomenon of principal "burn out" is the result of many conditions surrounding the principalship. First, as the number of students has risen over the last 40 years, the number of schools has declined. Too, teachers have become better educated and more specialized, making them less ready to accept the opinions and direction of…

PERHAPS THE MAJOR PROBLEM IN TASK ANALYSIS FOR INDUSTRIAL TRAINING IS TO DETERMINE WHAT TO DESCRIBE AND ON WHAT LEVEL OF DETAIL. MANY DIFFERENT LEVELS OF DESCRIPTION MAY BE NEEDED TO ESTIMATE THE COST OF INADEQUATE PERFORMANCE TO A SYSTEM AND THE PROBABILITY OF ADEQUATE PERFORMANCE WITHOUT TRAINING--THE PROBLEM OF IDENTIFYING DIFFICULT COMPONENTS…

This paper suggests that a change in mode of expression --narrative, descriptive, or expository--can influence the syntactic complexity of children's writing. The implications of the research studies reviewed here may offer direction for education in general. Instructional strategies which make use of variation in writing mode to encourage gains…
