The present study examined whether language/learning disabled children have greater difficulty than nondisabled children suppressing information that becomes irrelevant during a sentence processing and memory task. During study trials, children were asked to predict and remember the terminal nouns for a series of sentences that highly constrained a terminal noun. For half of the study trials (fillers) the child's prediction was confirmed by presenting the child with the expected ending (e.g., “Butterflies fly by flapping their . . .wings.”). For the remaining study trials (critical trials), however, the sentence ending expected by the child was disconfirmed with a low-probability ending (target noun). Thus, when presented with the sentence, “We made a sandwich with peanut butter and . . . ,” the child's prediction (“jelly”) was disconfirmed with a different ending (“bananas”). Memory for the disconfirmed and target nouns of critical study trials were subsequently tested implicitly with a new sentence-completion task. In this case, memory for disconfirmed and target nouns that had been associated with individual study sentences were measured in terms of priming effects. The analysis of priming effects indicated that language/learning disabled children experienced greater difficulty than nondisabled children inhibiting the activation of irrelevant information (disconfirmed nouns) and sustaining the activation of relevant information (target nouns) during a verbal memory task. These results were discussed in terms of their implications for some of the memory and language difficulties of language/learning disabled children. 相似文献

Average and advanced readers from the fourth and sixth grades read visually presented words as rapidly as possible. Target words were preceded by a related prime word, an unrelated word, or a neutral warning stimulus. Related trials constituted 75% of the word prime trials for half of the subjects in each group, and only 25% for the other half. All groups were sensitive to this proportion manipulation, showing only faster naming times for related targets in the 25% condition. In the 75% condition, subjects showed inhibition for unrelated targets, as well as facilitation for related targets. The results indicate that the ability to use context deliberately to facilitate word recognition reaches asymptote for the average reader by the sixth grade at the latest, and perhaps by the fourth. This ability does not appear to be one that shows further improvements at higher levels of reading skill. Some possible reasons for the discrepancies between this research and that using incomplete sentence contexts are considered. 相似文献

A teacher's orientation toward science teaching has been proposed as very influential to a teacher's pedagogical content knowledge (PCK) and teaching practice. Experienced teachers' orientation toward science teaching and its connections to their practice has not been well explored. Focusing on a unit about the periodic table, this study provides a case study using a respected, experienced high-school chemistry teacher's orientation toward science teaching to make sense of her observed teaching practice. Aspects of her practice, which aligned and misaligned with current recommendations for science teaching, were explored. Using observations, interviews, and class documents, the study concluded that the teacher's orientation toward science teaching was an appropriate way of understanding her teaching practice. While also being shown to be a useful tool for researchers, this case provides an example how a teacher's orientation toward science teaching could help in the development of professional development, specifically professional development for the recently released Next Generation Science Standards. 相似文献

The results of a recent study by Lorsbach, Melendez and Carroll‐Maher (1991) suggest that children with learning disabilities may possess a general deficit in remembering the source of their verbal memories. The purpose of the present study was to examine further whether children with learning disabilities possess a general deficit in source monitoring and whether such a deficit is independent of performance on a recognition memory task. Children with learning disabilities and nondisabled children were presented with a series of incomplete sentences once or twice in either a listen‐listen (external source monitoring) condition or a think‐listen (reality monitoring) condition. Following the presentation of the study‐list, subjects were presented with the terminal nouns of the preceding sentences and asked to make old/new recognition judgments, as well as source attributions. Although children with learning disabilities were deficient in both forms of source monitoring, they did not differ from nondisabled children in their recognition performance. The results suggest that children with learning disabilities possess a general deficit in verbal source monitoring. 相似文献

This study describes a collaborative study involving a teacher and university researcher using learning environment research to transform a middle school science learning environment. Habermas' idea of knowledge constitutive interests (technical, practical, and emancipatory) is used as a perspective to make sense of the learning environment. Student perceptions of science and the nature of science were explored. Classroom observations and student interviews were the primary data sources. Students perceived science as primarily a set of facts to be learned and did not view it as an inquiry method or a social process. Despite the characterization of the course by the teacher and students as hands-on and experimental, technical interests were prevalent. Through negotiation, a plan of action was outlined for recreating the learning environment to make it more practical and emancipatory, as well as more consistent with contemporary perspectives on the nature of science. 相似文献

Self-efficacy Theory and Learning Environment Research 总被引：3，自引：0，他引：3
The purpose of this article is to bring to the attention of educators interested in student perceptions of the learning environment
the concept of self-efficacy. Social learning theorists define perceived self-efficacy as a sense of confidence regarding
the performance of specific tasks. Our premise is that student self-efficacy beliefs regarding academic performance can have
important implications for improving learning environments and, consequently, student outcomes. We believe that focusing on
students' academic self-efficacy could alter student perceptions of the learning environment. Unlike most beliefs systems,
which can be highly personal, academic self-efficacy is generally a belief that is addressable in a classroom context. Therefore,
understanding more about the reciprocal relationship between the learning environment and students' academic self-efficacy
beliefs should be a fruitful focus for learning environment research.
