Following Cronbach (1970) and others, it is useful to decompose test score variation into common factor, time‐specific, item‐specific, and residual components. In the traditional approach to factor analysis, only two sources of variance can be estimated: common factor variance and a uniqueness term that confounds specific sources of variation and residual error. When the same items are measured on different occasions, however, it is possible to separate specific variance and residual error. Two approaches, the first‐order approach described by Raffalovich and Bohrnstedt (1987) and a second‐order approach based on Jöreskog and Sörbom (1989; Jöreskog, 1974) are considered initially. The two approaches, although based on different rationales, both suffer a similar weakness in that two of the four sources of variance are confounded. In the Raffalovich and Bohrnstedt approach, time‐specific variance is confounded with common factor variance that generalizes across items and time. In the second‐order approach based on Jöreskog and Sörbom, time‐specific variance is confounded with residual error. Here we demonstrate that by combining features from both approaches we can eliminate these weaknesses and estimate all four of Cronbach's sources of variance, and that this combined approach is easily generalized to a wide variety of applications. 相似文献

The purpose of the present study is to explore how academic self‐concept and implicit theories of ability are related to four self‐regulation strategies—motivation/diligence, concentration, information processing, and self‐handicapping. The hypothesis is that academic self‐concept and an incremental theory of ability are (1) positively related to motivation/diligence, concentration, and information processing strategies, and (2) negatively related to self‐handicapping strategies. On the basis of inventories 168 teacher students and 60 sport students (a total of 178 females and 50 males) were scored on academic self‐concept, incremental and fixed theories of ability and the four self‐regulation strategies. Multiple regression analysis was used for each self‐regulation strategy as dependent variable, and with academic self‐concept and the ability theories as independent variables. Results revealed that an incremental theory had, as predicted, a positive relation with motivation/diligence and concentration, but had only trivial relations with information processing and self‐handicapping, whereas a fixed theory had only the predicted relation with self‐handicapping. As hypothesised, a high academic self‐concept was positively related to motivation/diligence, conception, and information processing and negatively to self‐handicapping. The findings may indicate that, in order to promote meta‐theoretical processing and prevent student from self‐handicapping, it is important to strengthen academic self‐concept, and to foster an incremental conception of ability among students. 相似文献

A brief review of the social and educational context of Hong Kong shows that the publication of the General guidelines on moral education in schools in 1981, by the Hong Kong Education Department, marked a milestone in the development of moral education. The Guidelines explicitly asserted moral education as one function of schooling, whilst also formally recognizing the home and the community as two main influences. This paper narrates how three moral sources of influence – namely Confucian‐parental, Christian‐religious and liberal‐civic – have shaped the development of moral education in Hong Kong from 1973 to 2003. It then examines in more detail: parental influence at home – the Confucian moral source in Chinese family; schooling influenced by religious sources – taking Christian schools as an example; and the Independent Commission Against Corruption as an official agency for moral education – a liberal source calling for civic morality. In conclusion, the post‐colonial emergence of nationalistic influence in the recently constituted Chinese Special Administrative Region, advocating national identity as the new core value, is traced and the implications for future moral education in Hong Kong are considered. 相似文献

Arguments for the use of the practical syllogism for rules theories entail a claim that the practical syllogism represents an alternative model of man for scientific research. This analysis evaluates that claim by: (1) examining the structure of the practical syllogism and its accompanying logics; (2) comparing the logics of the syllogism with logics of human behavior; (3) identifying the contraints upon research by the action theory assumptions of the syllogism; and, (4) projecting these constraints upon three areas of substantive research ‐ mass, interpersonal, and organizational communication. 相似文献

This paper explores whether and in what ways young people's perceptions and experiences of higher education (HE) can facilitate the transmission within their social networks of social capital both upwardly (from child to parent) and horizontally (from sibling to sibling), and thus can potentially provide bridging capital to family members, especially in families with little or no prior experience of HE. It utilises data from a project that explored the embedded nature of decision‐making about HE amongst a group of ‘potentially recruitable’ adults and their wider networks. The study researched 16 networks, and the resultant sample of 107 individuals included six teenagers and 15 young people in their twenties. The paper concludes that, despite the general emphasis within existing theoretical approaches to network capital on the downward transmission of social capital, the educational experiences of younger generations can be critical in shaping the perceptions of other (including older) network members, albeit not always in ways that encourage formal educational participation. 相似文献

In New Zealand there is an increasing trend for people with prior occupational experiences to enter secondary teaching. At a time when the media is continually questioning the status and capability of the teaching profession, we explore what or who motivates people to change their occupational paths and enter the teaching profession. Our sample of 68 newly qualified change‐of‐career teachers reported multiple factors related to their decision to pursue teaching. The matrix of reasons involved a range of “push and pull” factors related to previous work and family experiences, values and task expectancies. Three cluster groups of teachers – “Looks Good”, “Time is Right” and “Teaching is Me” – were developed to illustrate the relative influence of different combinations of reasons. We looked at how these teachers' motivations and prior experiences impacted on early and long‐term career expectations and intentions. 相似文献

This paper draws on data from a research project investigating gendered identities and interactions of high‐achieving students in Year Eight in England (12–13 years old), particularly in relation to students’ ‘popularity’ amongst their peers. As part of this study 71 students were interviewed from nine different schools in urban, rural and small town locations. From an analysis of participants’ conceptions of the characteristics of ‘popular’ and ‘unpopular’ students, this paper looks in depth at notions of in/authenticity and how it is perceived and judged in relation to the self and others. In particular, the paper focuses on the genderedness of such discourses of in/authenticity as constructed by these students, and relates such concerns to theorizations of ‘impossible’ femininity. 相似文献

A total of three hundred and fifteen (n = 315) gifted students from the 10th and 12th grade from the United States (n = 102), China (n = 125) and Germany (n = 88) were surveyed regarding their motivation and self‐regulation in chemistry learning. A 3×2×2 MANOVA revealed “nation” as having the largest major effect on these variables. The American group scored higher in most of the motivational and self‐regulatory characteristics than their Chinese and German counterparts. Although in all samples gifted girls reported a higher effort goal orientation, they used superficial cognitive strategies in learning science more frequently than boys. In addition, students' effort goal orientation was less pronounced in higher grades in all samples. 相似文献

This study investigated the degree to which applicants' perceptions of interview behaviors differed from interviewers' perceptions. Data were drawn from 188 actual employment interviews conducted under the auspices of a university‐operated placement center. Data analyses revealed applicants rating themselves and the interviewers significantly higher than the interviewers' ratings of either themselves or the applicants. 相似文献

The importance of developing effective learning strategies and motivational beliefs has been widely acknowledged as a way of meeting the demand to acquire lifelong learning capabilities for successful functioning as professionals in the ‘information age’. The study reported in this paper examined the learning orientations and strategies of prospective teachers as well as their assessment preferences and compared them with those of in‐service teachers. The Motivated Learning Strategies Questionnaire (MSLQ) and the Assessment Preferences Inventory (API) were used to test the hypothesis that in‐service teachers will exhibit a deeper approach to learning and assessment due to their constant engagement in meaningful learning experiences. The results confirmed the hypothesis and their implications for teacher education programmes were then discussed. 相似文献

This article presents some of the findings of a research project on students who do degree courses at technical colleges. The aim was to explore the attitudes of students towards doing a degree at a technical college. It shows the mixture of positive and negative feelings and the slight swing towards a more favourable attitude during the first year, and points out that the most favourable attitudes occur where the college and the course are seen as fulfilling a function distinct from the universities. Where they do not, the technical college tends to be compared unfavourably. 相似文献

The purpose of this study was to determine whether significant group, gender, and grade differences existed in the preferred learning styles of gifted minority students. The Learning Style Inventory (Dunn, Dunn, & Price, 1987) was administered to 54 African‐American (20 males, 34 females), 61 third‐generation Mexican‐American (26 males, 35 females), and 40 third‐generation American‐born Chinese (25 males, 15 females) students. A three‐way analysis of variance on the LSI raw scores of gifted African‐American, Mexican‐American, and American‐born Chinese students indicated significant group differences in preferences for noise, light, visual modality, studying in the afternoon, and persistence. Significant gender differences were found in preferences for the tactile modality and intake. Finally, significant grade differences were found in preferences for temperature (warm/cool environment) and mobility. Findings support and extend past research regarding the learning styles of gifted students. 相似文献
