In this study, we compared 41 adults in a basic literacy class with 92 achievement-level-matched children on their use of English print conventions, as inferred by a qualitative analysis of spelling errors. The two groups followed similar patterns in their mastery of basic spelling features, including letter reversals, consonant blends, and short vowels, with the adults showing relatively more advanced skill in using orthographic patterns. However, the adults made a preponderance of misspellings that were rarely made by the children, including omissions, substitutions, and additions of derivational and inflectional morphemes, and neglect of word endings in general. The findings indicate clear morphological difficulties along with more subtle phonological coding deficits. We suggest that low literacy adults would benefit from specific direct instruction in linguistic analysis, with particular attention to the morphological principles underlying inflections and derivations. Such instruction should be based on a careful assessment of reading and spelling knowledge. 相似文献

Assessing Marital Conflict from the Child''s Perspective: The Children''s Perception of Interparental Conflict Scale 总被引:10,自引:0,他引:10
Guided by Grych and Fincham's theoretical framework for investigating the relation between interparental conflict and child adjustment, a questionnaire was developed to assess children's views of several aspects of marital conflict. The Children's Perception of Interparental Conflict Scale (CPIC) was initially examined in a sample of 222 9-12-year-old children, and results were cross-validated in a second sample of 144 similarly aged children. 3 factor analytically derived subscales (Conflict Properties, Threat, Self-Blame) demonstrated acceptable levels of internal consistency and test-retest reliability. The validity of the Conflict Properties scale was supported by significant relations with parent reports of conflict and indices of child adjustment; the Threat and Self-Blame scales correlated with children's responses to specific conflict vignettes. The CPIC thus appears to be a promising instrument for assessing perceived marital conflict, and several issues regarding its interpretation are discussed. 相似文献

Young Children''s Vulnerability to Self-Blame and Helplessness: Relationship to Beliefs about Goodness 总被引:8,自引:0,他引:8
Motivational helplessness, linked to conceptions of intelligence, has been well documented in older children. While some researchers have reported that children just starting school are motivationally invulnerable, others have found evidence of helplessness when these children encounter failure. The present study seeks to determine whether the reactions associated with helplessness can be identified in a new context, that of criticism, and whether any such responses are related to the child's conceptions of goodness. Subjects were 107 5- and 6-year-old children who enacted achievement situations in which teacher criticism was presented. The 39% of children whose own assessments were undermined by criticism exhibited the affect, task choices, and nonconstructive problem-solving strategies characteristic of helplessness. They were also more likely to make global negative self-judgments following criticism, including negative judgments of their goodness. Finally, these children were more likely to endorse stable and global beliefs about goodness. 相似文献

Pigeons searched for symbolic targets among heterogeneous distractor items displayed on a video monitor. Phase 1 varied target identity and overall display size, thus establishing differential discriminabilities of three target symbols. Phase 2 varied the relative probability of these targets within sessions. The findings showed that reaction time was lower not only when targets were more discriminable, but also when they were relatively frequent; these effects did not depend on the discriminability of the less frequent targets. Phase 3 was similar in design but provided occasional choice trials on which two targets appeared. The birds were more likely to respond to the more frequent target on such trials only if it was also the most discriminable. The data are not consistent with certain predictions from Guilford and Dawkins’ (1987) reinterpretation of effects attributed to search images. The data indicate that detection and choice are modified jointly by priming-induced expectancies and stimulus-driven perceptual processes. 相似文献

This article discusses the growing consensus across diverse educational research domains that the historical aspects of cognition are important for understanding not only how individuals but also disciplines know what they know. After proposing and defining the new superordinate concept of historicality, fundamental interrelationships between time, events, memory, meaning, personal knowledge, public knowledge, and the histories of the sciences are explored. Relevant research findings that demonstrate the confluence of scholarly thought concerning historicality across five educationally important domains are presented for the reader's consideration. Using the historicality concept, it is suggested that the histories of the sciences be considered as “the collective mind of scientists” and viewed as vital to developing students' knowledge about science by building upon the critical distinctions drawn by Duschl (1990). The author's science teaching technique, based upon construction of historical vignettes, is introduced here because of the relationship between history and story and the documented educational effectiveness of the story format. Finally, the author adds several cautionary notes about the validity of explanations based upon historicality and anticipates future advances in our understanding of the historicality of cognition. 相似文献

The elaboration theory of instruction: A model for sequencing and synthesizing instruction 总被引:1,自引:2,他引:1
Charles M. Reigeluth M. David Merrill Brent G. Wilson Reginald T. Spiller 《Instructional Science》1980,9(3):195-219
This paper describes a novel instructional model for sequencing, syntheizing, and summarizing subject-matter content. The importance of such models is discussed, along with the need for a significant change in the role of subject-matter structure in instruction. A zoom-lens analogy is presented to facilitate an understanding of the elaboration model of instruction. Some basic concepts and principles upon which the model is based are described. The basic unvarying components of the elaboration model are described. And finally, some variations in the model for different kinds of goals are described. The elaboration model follows a general-to-detailed pattern of sequencing, as opposed to the hierarchically based sequences derived from Gagné-type task analyses.Many of the ideas described in this paper were developed under two projeets, one funded by Brigham Young University in Provo, Utah, and the other by the Navy Personnel Research and Development Center in San Diego, California; however, the ideas expressed do not necessarily constitute the opinions of the funding institutions. 相似文献
