The purpose of this study was to determine the components of working memory (WM) that underlie less skilled readers' comprehension and word recognition difficulties. Performance of 3 less skilled reading subgroups---children with reading disabilities (RD) in both word recognition and comprehension; children with comprehension deficits only; and children with low verbal IQ, word recognition, and comprehension (poor readers)--was compared to that of skilled readers on WM, short-term memory (STM), processing speed, executive, and phonological processing measures. Ability group comparisons showed that (a) skilled readers outperformed all less skilled readers on measures of WM, updating, and processing speed; (b) children with comprehension deficits only outperformed children with RD on measures of WM, STM, phonological processing, and processing speed; and (c) children with RD outperformed poor readers on WM and phonological processing measures. A hierarchical regression analysis showed that (a) subgroup differences on WM tasks among less skilled readers were moderated by a storage system not specific to phonological skills, and (b) STM and updating contributed significant variance to WM beyond what was contributed by reading group classification. The latter finding suggested that some differences in storage and executive processing emerged between skilled and less skilled readers that were not specific to reading. 相似文献

With morerecent advances in the creation of nanocrystal withstrong ionic coupling (Hudgins et al., 1997), onenatural problem is that the effect of bipolarons insome quantum low dimensional systems with ef-fective electron-phonon coupling is very strongowing to the confinement.

There are multiple routes to becoming a special educator in Norway. In recent years, bachelor's degree programmes have offered an alternative to the traditional path in which special education coursework is taken as a part of teacher education. The purpose of this study was to investigate whether these different programmes produce different understandings of the special education profession and its core concepts. We surveyed 27 bachelor students and 36 teacher education students using open-ended questions concerning their future goals and expectations and the concepts of ‘inclusion,’ ‘learning disability,’ and ‘special educator’. Teacher education students were more likely to: (a) view inclusion from a broad perspective, emphasizing a sense of belonging and community, (b) define the concept of learning disability from a categorical perspective, and (c) perceive special educators as essentially ‘expert’ teachers for children with special needs. Bachelor’s degree students also emphasized special educators’ role in supporting individuals with special needs, yet were more likely to apply a relational perspective when describing the concept of learning disability. 相似文献

Background: Recently, there is a growing interest in independent learning approaches globally. This is, at least in part, due to an increased demand for so-called ‘21st century skills’ and the potential of independent learning to improve student skills to better prepare them for the future.
Purpose: This paper reports a study that explored the effectiveness of two different independent learning approaches: (i) guided independent learning and (ii) unguided independent learning with independent research, in enabling students in an undergraduate Macromolecules course to acquire knowledge in one chemistry context and apply it successfully in another.
Sample: The study involved 144 chemistry students commencing their first term of undergraduate study at a northern university in England. Students completed pre- and post-intervention tests containing 10 diagnostic questions, of which 4 measured students’ knowledge acquisition in one context and 6 measured their ability to apply it in another.
Design and methods: Diagnostic questions had been identified using a Delphi approach. Paired t-tests and chi-square tests were used to analyse the significance of any change in students’ responses to the diagnostic questions and the number of responses evidencing misconceptions, respectively.
Results: Whilst guided independent learning settings were found to improve students’ knowledge and ability to apply that knowledge in novel situations, unguided independent learning had no statistically significant effect. Unguided independent learning was also linked to a statistically significant increase in the number of student misconceptions in one of the diagnostic questions.
Conclusions: The results of this study show that guidance in independent learning activities is a key necessity for effective learning in higher education. This paper has strong relevance and high significance to tertiary STEM education, especially in the light of increased importance of teaching, such as the Teaching Excellence Framework in the UK, and shifts to more independent learning activities. 相似文献

Commentary is provided on 2 papers published in this issue, which suggest some risks in nonmaternal or out-of-home care (National Institute of Child Health and Human Development [NICHD] Early Child Care Research Network, this issue; Watamura, Donzella, Alwin, & Gunnar, this issue). In light of the findings, 2 child care policy options are examined: first, support for in-home care in the early years; and second, changes in the nature of out-of-home care. From ethnographic and experimental research, it is argued that out-of-home pre-elementary care can contribute positively to social development if it emphasizes (a) children's attachment to school and peer group, (b) constructivist rather than didactic learning, (c) intrinsic and internalized motivation, and (4) group structures that support social development. 相似文献

This qualitative–case study examined how portfolio and portfolio assessment were perceived by prospective teachers. The participants
were 23 prospective teachers from seven different teaching areas from a Turkish university. A semi-structured individual interview
was conducted. The interview schedule included 15 open-ended questions. The main results emerged from content analysis were
that prospective teachers perceived portfolio as a learning and an assessment tool. Further, they believed that portfolio
was complementary rather than an alternative assessment method to traditional assessment procedures. 相似文献

Co‐teaching – or the use of more than one teacher in a classroom – has been commonly recommended as a means to promote inclusive education. The aim of the present study was to survey the actual frequency of co‐teaching among different teacher categories in the comprehensive school level in one Finnish city. The data were collected through a questionnaire answered by two representative samples of teachers including 117 resource room teachers in the first survey, and 317 teachers of various teacher categories in the second. The results showed that co‐teaching was a widespread phenomenon among resource room teachers and special class teachers but less frequent among other teacher groups. Overall, it was used only infrequently, typically from two to three hours a week. On a weekly basis it was implemented by every second special education teacher, every third classroom teacher and every sixth subject teacher. A comparison with a study from the early 1980s confirmed that the relative popularity of co‐teaching had increased only slightly during the years. Although co‐teaching is used sparsely, the teachers reported almost uniquely positive experiences obtained from it. It is argued that the promotion of co‐teaching needs additional incentives if it is hoped to make it more common. 相似文献

ABSTRACTThis study explored preservice teachers’ (PSTs) perceived competencies and weaknesses in regard to working with a diverse range of students’ families, as well as what contributes to their level of preparedness to serve different family types. A sample of 25 Elementary Education PSTs completed surveys and participated in interviews related to their family-related coursework and experiences, memories of home-school connections, and future plans to connect with students’ families. Numeric frequencies of responses showed that PSTs felt the most prepared to serve traditional (‘nuclear’) families and the least prepared to serve divorced, single and same-sex parents. A thematic analysis revealed a contrast between participants who simply desired to serve and those who felt ready to serve different family types. Participants also rejected the notion of a ‘normal’ family, while simultaneously using heteronormative language when discussing different family types. The article offers implications for teacher educators. 相似文献

In the literature, student self‐assessment as a practice and as a goal in higher education is generally emphasized for academics. This paper reports a study that investigates what academics emphasize in their experiences of student self‐assessment. The investigation focused on the different ways academics described their understanding and practise of self‐assessment. A phenomenographic approach was used to research and identify a set of progressive variations of academics’ ways of experiencing student self‐assessment. Altogether, 16 academics from a variety of disciplines and programs of study in three Australian universities participated in the investigation. The consequent research findings describe five qualitatively different conceptions that depict how academics understand and use student self‐assessment. These findings are subsequently discussed in terms of the potential for academics to understand and use student self‐assessment to enhance students’ self‐assessment ability, to further students’ lifelong learning and to empower, rather than discipline, students. 相似文献

The decline in the popularity of physics over the period of secondary schooling and its consequent low uptake at A‐level and beyond continues to cause concern on educational and economic grounds. The aim of this study is to explore whether physics might be made more attractive to students by employing an extended range of classroom and laboratory activities to teach it. Specifically, the study scores the popularity of a range of activities, students’ perceptions about how often these activities are used to teach physics, and whether students consider them educationally useful. Students appear to think in terms of written activities, passive activities, social activities and constructive activities. Written activities are relatively unpopular and seen as educationally less effective, but students perceived them as used frequently. Social activities such as group work are more popular. The most popular activities are constructive activities, such as doing experiments; these are seen as educationally useful, but are perceived as being used less often than other activities. While there are legitimate limitations on the types of activities that can be used, these findings add to our appreciation of which teaching activities students like and value. 相似文献

Developing a teacher identity is an ongoing and multifaceted process. In part, the process involves finding a voice amid the clamour of other, often contradictory, voices and complex conditions in which teachers find themselves. Drawing from a larger study of teacher professional identities, this paper explores how two beginning early childhood educators talk about what it means to teach. The paper focuses on how these novice teachers position themselves, and are positioned, by their understandings of the ‘child’. This focus on children is particularly relevant to understanding teacher identities for in educational contexts, teachers and children are inextricably linked – they are part of a relational pair. Using critical discourse analysis as a way of examining interview data, I discuss how a discourse of the ‘normal’ child constructs particular identity positions for children and the adults who work with them. 相似文献

Quality of teaching in higher education has been widely discussed. It clearly underlines the importance of undertaking a multidimensional view about the teaching/learning process as well as involving the main actors of university life according to a participative model, in order to elicit their opinions about important quality issues. Moreover, some studies suggested that the importance of differentiating between the various disciplinary contexts determines which aspects are specific and which are transversal to faculties. On the basis of these assumptions, the aim of this study is to involve the students of various faculties in the identification of what constitutes ＂good teaching＂. Furthermore, the concept of ＂good teaching＂ is strongly linked to teaching evaluation, for this reason, it was considered important to verify differences in the attribution of importance of the various dimensions by students from different faculties, in order to understand if teaching evaluation in the university can take place without distinctions, or whether it should provide methodologies and instruments covering commonalties and differences for each disciplinary area. The results legitimize a complex approach to the issue and a diversified framework of competencies when considering different teaching contexts. 相似文献

The purpose of this study was to determine if students' values were different depending on which type of school they attended, and whether these values changed across the school year. Students of three different types of schools (private, state, religious) were measured at the beginning and the end of a school year, using the Schwartz Portrait Values Questionnaire 40. At both measurement times the analyses showed that the most significant differences between the types of schools were found for values of Tradition and Hedonism. Across all schools, the most notable changes were discovered for the values of Power and Achievement, lesser changes were found for Benevolence and Universalism. The impact of school on change in values was mediated by religiosity for Conformity, Tradition, Benevolence, Hedonism and Power. 相似文献

This paper explores students’ conceptions of good teaching in three different disciplines. Moreover, the aim is to explore the relation between these conceptions and students’ approaches to learning by combining qualitative and quantitative methods. A total of 695 students from the Faculties of Behavioural Sciences, Law and Veterinary Medicine participated in the study. The students’ conceptions of good teaching were analysed using a qualitative content analysis. Furthermore, the students were assigned to homogenous subgroups on the basis of their responses to items measuring approaches to learning and the differences between these subgroups and the students’ conceptions were examined. The association between the conceptions, disciplines and approaches to learning were examined using Chi‐square tests. Twenty‐one dimensions were created from the data and 12 of them differed between the disciplines. Only one dimension differed between the student groups. The study suggests that there is disciplinary variation in students’ conceptions of good teaching and universities should take this into account in the development process of the student evaluation system. 相似文献

Based on the Canadian Standards Association (CSA) criteria,105 pullout specimens were tested to investigate the effect of different rib geometries on bond strength of glass fiber reinforced polymer (GFRP) rebars embedded in concrete. Two kinds of conventional reinforcing rebars were also studied for comparison. Each rebar was embedded in a 150 mm concrete cube,with the embedded length being four times the rebar diameter. The experimental parameters were the rebar type,rebar component,rebar diameter,rebar surface texture,rib height,rib spacing and rib width. Theoretical analysis was also carried out to explain the experimental phenomena and results. The experimental and theoretical results indicated that the bond strength of GFRP rebars was about 13%～35% lower than that of steel rebars. The bond strength and bond-slip behavior of the specially machined rebars varied with the rebar type,rebar diameter,rebar surface texture,rib height,rib spacing and rib width. Using the results,design recom-mendations were made concerning optimum rib geometries of GFRP ribbed rebars with superior bond-slip characteristics,which concluded that the optimal rib spacing of ribbed rebars is the same as the rebar diameter,and that the optimal rib height is 6% of the rebar diameter. 相似文献

This paper uses individual-level data and a differences-in-differences estimation strategy to test whether the education gender gap of Muslims is different from that of Christians. In particular, the paper uses data for young Lebanese and shows that, other things equal, girls (both Muslim and Christian) tend to receive more education than boys and that there is no difference between the education gender gap of Muslims and Christians. Therefore, the paper finds no support for the hypothesis that Muslims discriminate against female education. 相似文献
