Attitudes toward occupations for deaf youth in Sweden.

The study investigated the expressed advice of parents, teachers, and Deaf community leaders regarding careers for deaf students in Sweden. The research was conducted: (a) in a country where consensus has been achieved on recognition and accommodation of the educational needs of deaf students; (b) in a city with a very high concentration of deaf individuals, a continuum of educational facilities, and support for deaf students ranging from preschool through college; and, (c) in a community with a strong and active deaf organization and parent organization. The authors found that, despite many advances in the country, communication in the language of the greater society is a potent factor in limiting occupational possibilities for the Deaf.

Adjunct aids in instructional prose: a multimedia study with deaf college students.

A computer-based science lesson was administered to 144 deaf college students grouped into low, middle, and high reading ability levels. Five instructional conditions were compared: (1) text only, (2) text and content movies, (3) text and sign movies, (4) text and adjunct questions, and (5) all of these together (full condition). The low reading level subjects in the adjunct question and full conditions demonstrated immediate, factual learning performance comparable to that of the high reading level subjects in the text-only condition. These and other results of this investigation suggest the compensatory potential of adjunct aids and associated mathemagenic activities to improve factual learning from instructional prose for low reading ability students.

Valid assessment of writing and access to academic discourse.

One way to improve students' access to and retention in post-secondary degree progams is to assess their readiness for such programs accurately. To place deaf and hard-of-hearing students in preparatory courses and to determine their readiness for degree programs more accurately, a direct measure of writing was developed for deaf and hard-of-hearing students at a large technical university. The purpose of this study was to estimate the concurrent and predictive validity of this measure. The Test of Written English (Educational Testing Service, 1992) served as the criterion in the concurrent validity study, and student success in the university's gateway freshman composition course served as the criterion in the predictive validity study. Results provide evidence of the concurrent and predictive validity of the measure, supporting its use for course placement and early planning purposes.

Working memory capacity and comprehension processes in deaf readers.

This research studied deaf students' performance on memory span and component reading tasks that incorporated processes involved in higher level comprehension. The instruments developed in the study provide the basis for the measurement of functional working memory capacity, vocabulary knowledge, domain-relevant knowledge, and inference abilities. Multiple regression analysis was used to construct models that show the contributions of the independent assessments to reading comprehension ability. Overall results suggest that working memory operates as a general executive system, as indicated by significant correlations between subjects' performance on reading and nonreading tasks. Limitations in vocabulary knowledge continue to pose problems in reading for deaf individuals. General or procedural knowledge also plays a part in reading comprehension processes.

Reading comprehension test item difficulty as a function of cognitive processing variables.

This study reports the results of a componential analysis of items comprising Sections A and C of Form Z of the reading comprehension portions of the California Achievement Tests (CAT) (Tiegs & Clark, 1963). A set of problem components or attributes characterizing the test items in terms of manifest content, psychologically salient features, and processing demands was developed, including methods for their quantification. The contributions of these components to task difficulty were then evaluated using linear regression methodology. Item difficulty indices were transformations of the familiar proportion-correct item score, obtained from data gathered during the spring of 1989 from 158 deaf examinees. Variation in the item difficulty values was substantially accounted for in terms of a small number of predictor variables (R2 greater than or equal to .90). Implications of the results for construct validity and interpretation of test scores are discussed.
