A study described machine operators' problem-solving actions at a computerized circuit-board assembly machine in a small manufacturing plant located on the West Coast. Participants were a machine operator and his supervisor, both from Vietnam, who were building large prototype boards for a major computer corporation. Over a 6.5 minute interval,…

"Thick descriptions" are descriptions that are layered enough to draw conclusions and uncover the intentions of a given act, event, or process. In a video environment, thick descriptions are images, gestures, or sequences that convey meaning. Neither the quantity nor the resolution of the images makes the descriptions thick. Thickness is…

This study compared the central capacity and the modularity models for explaining language processing in kindergarten children. Using a microcomputer, 19 kindergarten children completed a visual letter-matching task that required a manual response. An auditory tone was emitted by the computer in a separate trial also requiring a press. For the…

This paper presents three experiments examining competence in the domain of proportional reasoning in several age groups (adult, and children in kindergarten, first, third, and fifth grade). In the three experiments, subjects indicated which of two flower boxes had the greater density of flowers. In experiments 1 and 2, the flowers were presented…

Five experiments involving a total of 44 college students addressed the effects of intercomponent consistency on skill acquisition in a class of cognitively demanding tasks requiring rapid integration of information and rapid application of rules. The role of consistency of external stimulus-to-rule linkage in facilitating learning and performing…

Motion media refers to film, television, and other forms of kinesthetic media including computerized multimedia technologies and virtual reality. Imagery reproduced by motion media carries a multisensory amalgamation of mental experiences. The blending of these experiences phenomenologically intersects with the reality and perception of words,…

The decentralization policy of Tomorrow's Schools entrusted individual schools with their own operational funds, and responsibility for property and personnel decisions and for staff development. As a result, the role of the primary principal became wider, calling on new knowledge and skills. Principals were also given a greater workload and a…

This book is intended to help teachers and librarians introduce elementary school students to the concepts and aesthetics of art appreciation using some of the best picture books available. The book analyzes the artwork of more than 50 award-winning picture books from cover to cover, and shows teachers and librarians how to discuss the art of each…

Knowledge of the processes involved in visual and auditory perception, as well as basic understanding of the mechanisms employed by the human brain in transforming perceptions into cognitions are prerequisites for the study of television aesthetics. Numerous scientific studies now found in such diversified fields as perceptual psychology,…

This study investigated discrepancies in partners' skills that arose during children's collaborative problem solving. Some researchers have concluded that expert peers' poor teaching skills seriously curtail the learning potential of expert-novice peer collaboration. This study examined the ways in which experts and novices negotiate and…

The results of a Wellington (New Zealand) project to develop science instruction materials for teachers with non-native learners of English are presented. The first section describes the project, which involved the collaboration of science teachers and English-as-a-Second-Language (ESL) specialists, offers general guidelines for language learning…

As many as 40% of older people in the United States live long enough to become great-grandparents, yet little is known about the content of this role within the American kinship system. Great-grandparents (N=20) living in the South responded to a depth anthropological interview which explored their perceptions of great-grandparenthood as a kinship…

To determine whether deficits warranting intervention are present in the later functioning of high-risk infants, 22 premature infants who experienced asphyxia or chronic lung disease (CLD) but who had no gross developmental abnormalities were evaluated. Assessments of auditory perception and receptive language ability were made during later…

G. Wolford's perturbation model of letter identification is designed to account for identification errors of briefly presented characters. Its chief assumptions are that features are extracted in parallel, that some of these features become perturbed or mislocalized, and that mislocalizations are more likely to occur in the direction of the fovea…

This discussion encompasses how people come to recognize moral obligations, how they arrive at moral judgments of themselves and others, and how the individual employs moral judgments to guide his own behavior. (Author/AM)
