This study sought to determine if there is a change in information processing and channel capacity as the human organism grows older, and if this relationship is altered with a change in stimulus complexity and dimensionality of the stimulus presented. With the human organism considered as a communication system, the use of absolute judgments to…

The fleet performance of a small group of Project 100,000 (low aptitude) personnel was assessed by means of an evaluation form completed by their supervisors after the men had been on board for approximately seven months. The men had previously been trained for the Navy rating, Aviation Structural Mechanic S (Structures), AMS. The performance of…

A mathematical model for computer-aided instruction has been developed. The assumption is made that the course is divided into a hierarchy of levels of difficulty and that if a student is able to perform successfully at a given level of difficulty, he can also perform successfully at all levels of lesser difficulty. Furthermore, if a student…

This study developed prototype diagnostic and teaching materials to test logical reasoning ability in second, third, and fourth grade pupils. The testing procedure attempted to find the most difficult levels, along several dimensions, at which a child can use a logical rule. The materials dealt with the rule for "or" elimination and the rule for…

Nine moderately/severely retarded adolescents and young adults were trained to use coin-operated washing machines using three types of materials: artificial (pictures), simulated (cardboard replicas), and natural (realistic). Most students increased their laundry performance with all three sets of school-based material, but generalization to…

Samples of the communicative behavior of a group of mildly mentally retarded adults were examined for indications of mature linguistic competence (specifically, grammatical morpheme and complex sentence use).Findings confirmed the expectation that the eventual mastery of these aspects of linguistic competence in higher-level retarded individuals…

Investigation of the simultaneous effects of and interaction between both culture-specific content schemata and formal schemata on English as a second language reading comprehension revealed that familiar content and rhetorical form yielded good reading comprehension. Results for "mixed" conditions indicated that content schemata affected reading…

Suggests that, in the majority of the aspects of the reading process examined, there was a statistically significant interaction between illustration and difficulty levels. Finds that reading performance in the illustrated conditions was superior to that in the unillustrated conditions at the lower level of difficulty. (JD)

Based on the standard setting procedures or the American Board of Preventive Medicine for their Core Test, this article describes how Rasch measurement can facilitate using test content judgments in setting a standard. Rasch measurement can then be used to evaluate and improve the precision of the standard and to hold it constant across time.…

This study of individual differences in performance of a geometric analogies task included four-alternative test items and studied eye movements and confidence judgments as well as latency and error. Results were interpreted using two hypothesized performance strategies: constructive matching and response elimination. (Author/BW)

Describes a study which used a graduate-level business game to examine consequences of objectively determined fit between managers' specialized competence and their functional roles in terms of individual and group performance. The game simulates a work environment of top-level management in industrial firms with responsibility for making…

An examination of the need for academic advising and tutoring for upper division students of the Open University in Scotland reveals a gap between institutional recommendations and the actual use and perception of the services. Clearer guidance is recommended for tutor-counselors, and questions are posed about service needs for further…

As many as two in five recent high school graduates say that there are gaps between the education they received in high school and the overall skills, abilities, and work habits that are expected of them today in college and in the work force. The majority of college students and high school graduates without a college degree say that they have…

A study explored similarities and differences in relative pronoun use by native speakers (NSs) and non-native speakers (NNSs) of English. The study was conducted with 40 university students, 20 NSs and 20 NNSs. Specifically, the study examined the frequency of relative pronoun use and the spontaneity of subjects' responses in completing a sentence…

The operating characteristics of 114 mathematics pretest items from the Praxis I: Computer Based Test were analyzed in terms of item attributes and test developers' judgments of item difficulty. Item operating characteristics were defined as the difficulty, discrimination, and asymptote parameters of a three parameter logistic item response theory…
