The popularity of social media sites for posting pictures has given rise to a new form of mediated communication: online photo sharing. This article explores motivations for sharing photos online, using the 2-step procedure common in Uses and Gratifications research. Focus groups revealed 42 motivations which were rated in importance by survey respondents (N = 460). Factor analysis revealed 4 classes of gratifications: seeking and showcasing experiences, technological affordances, social connection, and reaching out. These results suggest that photo sharing is driven by social needs and facilitated by interface features, with important implications for theories of technology and user psychology. 相似文献

Relational analysis of personal epistemology and conceptions about teaching and learning 总被引:3,自引:0,他引:3
Four epistemological belief and two teaching and learning conception dimensions were identified from a survey study of a sample of Hong Kong teacher education students. The epistemological belief dimensions were labeled Innate/Fixed Ability, Learning Effort/Process, Authority/Expert Knowledge and Certainty Knowledge. The results on epistemological beliefs were somewhat different from Schommer's findings with North American college students and reflected the influence of cultural contexts. The two teaching and learning conceptions were labelled Traditional and Constructivist Conceptions. Pearson correlation analysis showed significant relations between Innate/Fixed Ability, Authority/Expert Knowledge and Certainty Knowledge with Traditional Conception and Learning Effort/Process with Constructivist Conception. Confirmatory factor analysis also showed the possible causal effect of epistemological beliefs on conceptions about teaching and learning. All these analyses tended to support the suggested views in literature that teachers’ conceptions about teaching and learning are beliefs driven. Implications were drawn for future research in teacher education with respect to the relation of epistemological beliefs and teaching/learning conceptions in different cultures. 相似文献

Although structural equation modeling (SEM) is one of the most comprehensive and flexible approaches to data analysis currently available, it is nonetheless prone to researcher misuse and misconceptions. This article offers a brief overview of the unique capabilities of SEM and discusses common sources of user error in drawing conclusions from these analyses. We make recommendations to guide proper analytical practices and appropriate inferences and provide references for more advanced study. © 2007 Wiley Periodicals, Inc.

This study investigates how different types of prior knowledge influence student achievement and how different assessment measures influence the observed effect of prior knowledge. We introduce a model of prior knowledge that distinguishes between different types of prior knowledge and uses different assessment measures to assess different types of knowledge. The sample consists of 202 mathematics students who completed the prior knowledge test during the first lesson. The student achievement was measured by the final grade on the course. The results indicate that the type of prior knowledge makes a difference: The measures assessing procedural knowledge predicted the final grades best whereas measures assessing declarative knowledge did not predict final grades. Additionally, previous study success was the best predictor of student achievement. These results are discussed in relation to assessment measures and their implications for practice. 相似文献

The public funding of early years education and care in England has been transformed. Historically, local councils had the main responsibility for decisions regarding nursery education and child day care, but in 1996 the Conservative government introduced a nursery education voucher scheme. Parents of four-year-olds could exchange the voucher for three terms of part-time ‘preschool provision’ in a state maintained nursery or primary school, or in a private, voluntary or independent (PVI) provider of child day care; in 1998, the Labour government replaced the voucher with an entitlement to free part-time ‘early education’. The entitlement was expanded progressively and in 2017 the Conservative government introduced 30 h per week free ‘childcare’ for some children, together with an Early Years National Funding Formula. Funding goals and policy have shifted over time, underpinned by the idea of ‘a level playing field’ between providers in maintained and PVI sectors. However, there is no statutory requirement for PVI settings to employ qualified teachers, militating against a genuine ‘level playing field’ and the integration of education and care. 相似文献

A procedure for the detection of differential item performance (DIP) is used to investigate the relationships between characteristics of mathematics achievement items and gender differences in performance. Eight randomly equivalent samples of high school seniors were each given a unique form of the ACT Assessment Mathematics Usage Test (ACTM). Students without requisite mathematics courses were deleted from the samples to reduce the confounding effects of differences in instruction at the high school level. Signed measures of DIP were obtained for each item in the eight ACTM forms. These DIP estimates were then analyzed in a 6 × 8 (item category by form) experimental design. A significant item category effect was found indicating a relationship between item characteristics and gender-based DIP. Predictions, based on previous research about the categories of items that would contribute to gender-based DIP, were supported: Geometry and mathematics reasoning items were relatively more difficult for female examinees and the more algorithmic, computation-oriented items were relatively easier. 相似文献

The present study investigates whether the Early Development Instrument (Offord & Janus, 1999) measures school readiness similarly across different groups of children. We employ ordinal logistic regression to investigate differential item functioning, a method of examining measurement bias. For 40,000 children, our analysis compares groups according to gender, English-as-a-second-language (ESL) status, and Aboriginal status. Our results indicate no systematic measurement differences regarding Aboriginal status and gender, except for 1 item on which boys are more likely than girls to be rated as physically aggressive by Kindergarten teachers. In contrast, ESL children systematically receive lower ratings on items of the language and communication domains—as expected by definition of ESL status—but not within the physical, social, and emotional domains. We discuss how our results fit with child development research and the purpose of the Early Development Instrument, thus supporting its validity. 相似文献
