Language tests were administered by videotape to 27 deaf children taught to sign English. The tests, one in manual English (ME) and the other in American Sign Language (ASL) each included twelve grammatical distinctions: two aspects of adjectival modification (opposition and ordering), two types of pluralization (is/are and indicative in ME, dual…

Eighty soldiers with the same appropriate occupational specialty (armor crewman) were randomly assigned to either a simple or a complex audiovisual lesson format to determine the effect of visual art on mastery of instructional material. The audio parts of the two versions were identical, but the visual art on the revised filmstrip was simplified…

Results indicated that discovery subjects took significantly longer than verbal reception subjects in the first-, third-, and sixth-grades to reach the original learning criterion. Verbal reception subjects generally demonstrated performance which was superior to discovery subjects on all measures of retention and transfer. (Author/BJG)

Two studies were performed to investigate the effects of material and task variations in the acquisition of cognitive learning strategies. Groups of undergraduate students were taught to use mental imagery, meaningful elaboration, and grouping. The type of training task or the order of training and test materials differed for each of the…

Two experiments assessed the effect of vocabulary difficulty on three measures of text comprehension--free recall, summary recall, and sentence recognition. In the first experiment, the effect of differing proportions of rare-word substitutions were examined in 79 sixth grade students. It was found that a high rate of difficult vocabulary (one…

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…
