The role of prior knowledge in inferential processing     

Rebecca Fincher-Kiefer 《Journal of Research in Reading》1992,15(1):12-27

The present research tested how domain-related knowledge influences inference generation during text comprehension. Two types of inference were examined, those that maintained referential coherence, referred to as local inferences, and those that were anticipatory in nature, referred to as global inferences. Three groups of subjects, each with differing degrees of domain knowledge, read a domain-related text that included both types of inference. It was found that all knowledge groups processed sentences involved in local inferences similarly, presumably because establishing text coherence is essential to comprehension. However, knowledge differences emerged in the processing of the sentences involved in global inferences. The results of two experiments suggested that individuals with prior knowledge used their knowledge actively to generate global inferences during reading. It was argued that this anticipatory inferential process guides the construction of a mental model of a text, built partly with explicit information and partly with existing knowledge.  相似文献   

Understanding children's epistemic beliefs in elementary education     

Jo Lunn Brownlee  Elizabeth Curtis  Rebecca Spooner-Lane  Florian Feucht 《Education 3-13》2017,45(2):191-208

Research shows that the beliefs individuals hold about knowledge and knowing (epistemic beliefs) influence learning approaches and outcomes. However, little is known about the nature of children's epistemic beliefs and how best to measure these. In this pilot study, 11 Australian children (in Grade 4 or Grade 6) were asked to ‘draw, write and tell’ about their epistemic beliefs using drawings, written responses and interviews, respectively. Drawings were analysed, with the majority of children depicting external, one-way sources of knowledge. The written statements and interviews were analysed using inductive thematic analysis, showing that children predominantly described knowledge acquisition as processes of task-based learning. Interviews also enabled children to describe a wider range of views. These results indicate that the methodological combination of ‘draw, write and tell’ allowed for a deeper understanding of the children's epistemic beliefs which holds implications for future research.  相似文献

Rebecca Abraham  P. L. Ogra 《Indian journal of clinical biochemistry : IJCB》1996,11(2):134-141

The development of the Polymerase Chain Reaction (PCR) has been a major technical milestone in molecular genetics with the greatest impact on research, in rapid medical diagnosis and in studying the pathogenesis of disease. This study highlights the practical applications of polymerase chain reaction in diagnosis and includes a recent application of PCR in differentiating polio from other nonpolio enteroviruses.  相似文献   

Theory of Mind: a Hidden Factor in Reading Comprehension?     

Rebecca A. Dore  Steven J. Amendum  Roberta Michnick Golinkoff  Kathy Hirsh-Pasek 《Educational Psychology Review》2018,30(3):1067-1089

Theory of mind is the understanding that other people have mental states that drive their actions and that those mental states can be different from one’s own. Without understanding theory of mind and being able to take others’ perspectives, it could be difficult for children to read and understand narrative texts. This paper posits that children’s understanding of others’ minds may be a potential missing piece in current accounts of reading comprehension. Indeed, the typical progression of children’s theory of mind abilities across childhood is closely aligned with the development of narrative processing skills. Furthermore, emerging evidence shows that both narrative processing and theory of mind are predictive of children’s reading comprehension, both concurrently and longitudinally. We present a possible explanation for why such a link exists and propose a causal framework of this relation in which increased ToM leads to increased understanding of and inferencing about characters’ mental states. Understanding characters’ mental states then leads to better reading comprehension. The framework makes novel, testable predictions and provides directions for future research.  相似文献   

We belong together: belonging to the principal’s in-group protects teachers from the negative effects of task conflict on psychological safety     

Rebecca Gerlach  Christine Gockel 《School Leadership & Management》2018,38(3):302-322

Psychological safety is the shared belief that the team is safe for interpersonal risk-taking. Critical team events such as conflict and faultlines (hypothetical lines that split a team into subgroups) should impact psychological safety. Previous research has shown the benefits of task conflict on team outcomes under certain conditions and the consistently negative effects of demographic faultline strength on team outcomes. We propose that being close to the principal (what we call belonging to the principal’s in-group) should help attenuate the negative effects of task conflict and faultlines among teachers, because it is associated with a more effective working relationship. In a survey study with 244 teachers from 45 primary schools, we tested the moderating effect of belonging to the principal’s in-group vs. belonging to an out-group on the relationships of task conflict and faultlines on psychological safety. Results of multilevel model tests showed that relationship conflict (but not task conflict) and faultlines decreased psychological safety. However, when teachers belonged to the principal’s in-group as compared to an out-group, task conflict had no negative effect on psychological safety. We present implications to bridge the negative effects due to subgroup presence, so that psychological safety can become a resource for all.  相似文献   

Educators’ perceptions of learners with intellectual disabilities’ sexual knowledge and behaviour in KwaZulu-Natal,South Africa     

Paul Chappell  Rebecca Johns  Siphumelele Nene  Jill Hanass-Hancock 《Sex education》2018,18(2):125-139

Over the past two decades, comprehensive sexuality education has increasingly been recognised as a measure that positively impacts on the sexual behaviour of young people in Africa. Despite this, and a political call to scale-up the use of comprehensive sexuality education in schools in South Africa, learners with disabilities continue to be left behind. Besides contending with negative hegemonic constructs of disabled sexualities, educators of learners with disabilities lack skills and resources to teach sexuality in accessible formats. Based on this premise, a comprehensive sexuality education approach – Breaking the Silence – was developed and piloted to assist educators of learners with disabilities to provide access to comprehensive sexuality education in KwaZulu-Natal, South Africa. This article presents results from the formative evaluation of this pilot work and discusses educators’ perceptions of their learners with intellectual disabilities’ sexual knowledge, agency and behaviour after implementing the approach. Although educators appeared to situate learners with intellectual disabilities as sexual agents, their implementation of the approach was dependent on the cognitive ability of learners, and discourses of culture, gender and protection from violence.  相似文献   

Do pupils from low-income families get low-quality teachers? Indirect evidence from English schools     

Rebecca Allen 《牛津教育评论》2018,44(4):441-458

Gaps between the educational attainment of pupils from higher and lower income families are widespread and persistent. Teacher quality is amongst the most important school-based determinants of pupil attainment, making the allocation of teachers to pupils a potentially important reason for this attainment gap. We use a range of well-evidenced indicators of teacher quality from the School Workforce Census and the Teaching and Learning International Survey to investigate the extent of social inequalities in access to teacher quality in England. Looking at the allocation of teachers between schools, we find that disadvantaged pupils are more likely to have unqualified, inexperienced or out-of-subject teachers. We present evidence that this reflects both demand from early-career teachers to work in such schools and a greater supply of vacant positions in these schools, due to poor staff retention. We find some evidence of an inequitable allocation of teacher quality to classes within schools, though this is limited to our teacher experience indicator. This is in part due to teachers with more experience at a specific school being better able to influence their allocation to less disadvantaged classes. Implications for policy are discussed.  相似文献

Interview Experiences and Diversity Concerns of Counselor Education Faculty From Underrepresented Groups          下载免费PDF全文

Angie D. Cartwright  Janeé R. Avent‐Harris  Rebecca Beck Munsey  Jessica Lloyd‐Hazlett 《Counselor Education & Supervision》2018,57(2):132-146

The authors used transcendental phenomenology to explore the campus interview experiences and diversity concerns of counselor education faculty from underrepresented populations. Six themes were identified: issues of integrity, disappointment in the counseling profession, importance of authenticity, intersectionality of major identity markers, competence, and supportive experiences. Findings suggest that culturally competent search committees should be aware of biases and policies promoting institutional and systemic discrimination.  相似文献   

Examination of the Six Minute Walk Test to Determine Functional Capacity in People with Chronic Heart Failure: A Systematic Review     

Brittany Pollentier  Sonya L. Irons  Courtney Manfredi Benedetto  Anne-Marie DiBenedetto  Dana Loton  Rebecca Diane Seyler  Mira Tych  Roberta A. Newton 《Cardiopulmonary Physical Therapy Journal》2010,21(1):13-21

Purpose: To evaluate the reliability and validity of the six-minute walk test (6MWT) with respect to its ability to predict functional capacity in patients with chronic heart failure. Methods: A systematic review was performed via 8 databases to assess relevant English language full-text articles published from January 1, 1980 to October 31, 2009. Participant characteristics, interventions, reliability, validity, and predictive value for each article with respect to functional capacity as defined by peak VO₂ levels were extracted and compared. Quality Assessment of Diagnostic Accuracy Studies (QUADAS) scores were determined for each study. Results: Fourteen studies met the selection criteria. Comparison of the studies investigating reliability shows that the 6MWT has good reproducibility. The 6MWT demonstrates moderate correlation with peak VO₂ levels, and ability to predict VO₂ (functional capacity) dependent on distance walked. Cut-off distances vary from 300 to 490 meters depending on the study; if total distance walked remains equal or less than these values, the 6MWT retains its strong predictive value. Conclusion: The 6MWT has good reliability, moderate validity, and a significant ability to predict functional capacity in patients with CHF who do not walk greater than 490 meters.Key Words: six-minute walk test, chronic heart failure, functional capacity, peak VO₂  相似文献
