This study assessed the effects of text topicalization conditions (initial position, final position, or no topic sentence) on the comprehension of main ideas and specific passage information for middle school readers. Also of interest were interactions of topic familiarity and readers’ cognitive styles (degree of field independence) with text topicalization. One hundred and seven subjects were randomly assigned to one of the three topicalization conditions and read three familiar and three less‐familiar multipleparagraph expository texts. Main idea comprehension was assessed with both a sentencesummary (generation) and best‐title (recognition) task. Comprehension of specific passage information was evaluated with multiple‐choice items. Text topicalization effects were observed for main idea comprehension (with initial position best, followed by final position), while topic familiarity resulted in higher comprehension scores for specific passage information. Moreover, a cognitive style‐text topicalization interaction was found on the best‐title task; in this case, relatively field dependent readers were assisted by a final topic sentence placement. Implications are drawn for future research concerning the complex interplay of texts, tasks and readers in prose‐processing. 相似文献

The goal of this study was to examine the means used by textbook authors to introduce, define, and explain the mole concept in high school and introductory college chemistry textbooks. The analysis was framed by four questions:
- 1 How is the mole defined?
- 2 What concepts about the atom are introduced prior to the mole?
- 3 Is Avogadro's constant presented as an experimentally determined value?
- 4 What is the context for introducing the mole?
- 1 Two ways of defining the mole dominate the texts. One way defines the mole as Avogadro's number (6.02 × 1023) particles; the other method defines the mole in terms of carbon-12.
- 2 All texts that present a definition in terms of C-12 introduce and define concepts about the atom prior to introducing the mole.
- 3 Most texts at all levels point out that the value 6.02 × 1023 is an experimentally determined quantity.
- 4 Nearly all texts discuss the mole in relation to die problem of finding a way to count particles that are too small to be directly weighed. Most texts also use a familiar counting unit, such as the dozen, to introduce the mole by analogy.

This article attempts to analyse the ongoing debate regarding open-mindedness as an educational value. The views of Hare, McLaughlin and Gardner are considered. They do not always agree on what open-mindedness is, and the discussion could benefit from a more unified terminology and better counter-examples. The value and limitations of open-mindedness in both science and the humanities are discussed and analysed. It is argued that open-mindedness, while clearly a virtue if not taken to excess, need not be a goal of the educational process. 相似文献

This study investigated whether humans have two mind‐reading systems whereby the efficient system, unlike the flexible system, is naturally limited. There were two experiments and the first included adults as well as children (3‐ to 4‐year‐olds; total N = 128). In Experiment 1, all groups efficiently gazed in anticipation of an agent's beliefs about object location but not object identity (an ambiguous figure). In Experiment 2, children showed limits in anticipating a competitive agent's action in terms of his perspective on what is desirable. Flexibility in verbally predicting agents' actions across contexts developed with age. Convergence on signature limits across different ages and methods suggests that indirect anticipations involve minimal mind reading, whereas direct predictions tap a refined understanding of perspective. 相似文献

This mixed methods study explores a service-learning experience embedded in a social foundations course in a teacher education program. The authors differentiate learning outcomes for social justice and charity service-learning, and utilize this framework to examine whether the service-learning experience fosters a social justice perspective. The findings demonstrate that while the experience did foster social justice perspectives for some students, the data also reflect evidence of learning outcomes that align with charity service-learning. 相似文献

Given the crucial role of suppliers in collaborative supply chains, it is surprising that little attention has been paid to the nature and management of supplier relationships in the implementation of a retailer's Customer Relationship Management (CRM) strategy. To address this gap in the extant literature, the theory of organizational justice is used to explore the extent to which perceived fairness in buyer–supplier relationships supports or inhibits supplier engagement with the CRM process. The rationale is that suppliers who feel fairly treated by key retail customers are more likely to invest resources in the acquisition and use of data central to the retailer's CRM strategy. By empirically testing a conceptual model linking downstream CRM to upstream SRM, the results provide evidence to indicate that customer data use is significantly influenced by perceptions of fairness, particularly with respect to the distribution of rewards, and the transparency of decision-making processes. As a key criticism of CRM centers upon the failure of organizations to exploit the full potential of customer data, the results highlight the usefulness of understanding the relational linkages between buyers and suppliers and the consequential behavior of suppliers in terms of engagement with customer data vital to the success of retailers’ CRM strategies. 相似文献

By and large, we think (Strevens's [2005]) is a useful replyto our original critique (Fitelson and Waterman [2005]) of hisarticle on the QuineDuhem (QD) problem (Strevens [2001]).But, we remain unsatisfied with several aspects of his reply(and his original article). Ultimately, we do not think he properlyaddresses our most important worries. In this brief rejoinder,we explain our remaining worries, and we issue a revised challengefor Strevens's approach to QD.
- 1 Strevens's clarifications
- 2 Strevens's new-and-improved negligibility arguments

Given the high prevalence of HIV/AIDS in Kenya, more Kenyans now find themselves in the role of informal caregiver for a family
member or multiple family members living with HIV/AIDS. However, there exists little research on how these individuals cope.
The present study explores coping responses among caregivers for family members living with HIV/AIDS in Kenya. An exploratory
factor analysis of the Brief COPE yielded five factors, with strong loadings on Emotional Support and Instrumental Support.
Implications for using the Brief COPE in research and clinical practice among Kenyans are discussed. 相似文献

Elementary and special education teachers and school counsellors currently provide support to children presenting learning disabilities and behavioural problems symptomatic of the more hidden diagnosis of complex trauma resulting from abuse or severe attachment disruption. Specific disorders such as attention deficit/hyperactivity disorder (AD/HD) may be diagnosed in such children, but not the aetiology of complex trauma, resulting in missing information in the development of remedial and behavioural interventions. The evolving field of trauma counselling provides important information to special education teachers and school counsellors who work with children who have experienced trauma. In this review article authors Linda O'Neill of the University of Northern British Columbia (UNBC), Francis Guenette who is a doctoral student at the University of Victoria and Andrew Kitchenham of the University of Northern British Columbia summarise attachment, neurobiological, and complex trauma research that can be used in school settings to understand better the needs of these children. They conclude by suggesting that teachers and school counsellors would benefit from training on the consequences of childhood trauma and attachment disruption to develop interventions that will be effective and to identify what types of behaviours children can control and those they cannot. 相似文献
