A Distribution Free Interval Estimate for Coefficient Alpha     

Laura Trinchera  Nicolas Marie  George A. Marcoulides 《Structural equation modeling》2018,25(6):876-887

Scales are important tools for obtaining quantitative measures of theoretical constructs. Once a set of measures to be used in a scale is selected, reliability is commonly examined in order to assess their measurement quality. To date, Cronbach’s coefficient alpha is the most commonly reported index of measurement quality for assessing scale reliability. In this paper, an asymptotic distribution of the natural estimator of coefficient alpha is derived. A new interval estimate and a statistical test on the significance of the sample estimate of the coefficient are also presented. The proposed approach is compared to four popular methods commonly used to compute confidence intervals (CI) for alpha using a Monte Carlo simulation study. An R function for implementing the proposed CI approach is also provided.  相似文献   

Fleeing through the globalised education system: the role of violence and conflict in international student migration     

Ane Marie Ørbø Kirkegaard  Sisse Mari-Louise Wulff Nat-George 《Globalisation, Societies & Education》2016,14(3):390-402

ABSTRACT

This article connects directly to the globalisation of both education and conflict, and attends to the intersection between these phenomena, by focusing on conflict-induced student migration, an area, which has until recently been neglected in studies of higher education and migration, and peace and conflict research. The focus is on the very intersection of these research traditions in trying to understand how increasing globalised student migration is intertwined with the internationalisation of higher education and violent conflicts. The research on which this article is based was carried out at Malmö University, Sweden. The focus is on mapping the linkages between violent conflicts and student migration, using a mixed methods design.  相似文献   

Bending the rules: when deaf writers leave college     

Biser E  Rubel L  Toscano RM 《American annals of the deaf》2007,152(4):361-373

On-the-job writing of deaf college graduates at all degree levels was investigated. Institutional databases and questionnaires to alumni and employers were the sources for information. Respondents were asked about editing assistance, sources and types of assistance, and perceptions of such assistance by employers and employees. Results of the study confirmed that deaf employees did considerable writing regardless of degree or type of job. Their self-reports indicated grammar as the major weakness. Additionally, employers stated that clarity, organization, and spelling were serious writing problems. The study also showed that deaf employees asked for and received editing assistance and that employers were willing to support the improvement of writing skills. Because error-free texts are expected in the workplace and editing assistance is sought and received, postsecondary institutions should mimic these practices by providing copyediting services and instruction in the ethics and practices of working with editors.  相似文献   

Science student role: Evidence of social structural norms specific to school science     

Marie‐Claire Shanahan  Martina Nieswandt 《科学教学研究杂志》2011,48(4):367-395

Sociocultural studies of science education have consistently recognized the dialectic nature of students' agency to create and author positions for themselves and the structural constraints that may influence them. This mixed‐methods study explores one particular aspect of these potential constraints: the possibility of a social structure specific to school science, using the concept of a science student role as an indicator. The first phase of the study was qualitative and exploratory, using open‐ended questionnaires and interviews to understand students' views of the expectations placed on them as science students (n = 95). The second phase was quantitative (using items developed from the qualitative analysis), with both exploratory and confirmatory elements (n = 157). Results suggest clear and explicit role understandings among these students, characterized by references to expectations of intelligence, experimental skill, scientific mindedness, and appropriate classroom behavior. The consistency of these expectations across genders, science teachers and schools provides evidence that there is an element of social structure specific to school science that needs to be considered in studies of student agency and identity. © 2010 Wiley Periodicals, Inc., Inc.

A multilevel analysis of student perceptions of school climate: The effect of social and academic risk factors     

Weihua Fan  Cathy M. Williams  Danya Marie Corkin 《Psychology in the schools》2011,48(6):632-647

This multilevel study examines the extent to which individual‐ and school‐level variables are predictive of three aspects of students' perceived school climate (order, safety, and discipline; fairness and clarity of school rules; and teacher‐student relationship) by using a nationally representative sample. A wide range of social and academic risk factors at the individual level are examined. The results show that individual‐level predictors, such as having behavior problems at school, being held back a grade, coming from a single‐parent family, parents' education level, gender, and ethnicity (e.g., Hispanic and Asian), play a significant role in student perceptions of school climate. The results suggest that these relationships between the individual‐level predictors and students' perceived school climate are fairly robust across schools. School‐level variables, such as attending a private or a Catholic school, are also significant predictors of students' perceived climate. Furthermore, the study reveals significant interaction effects among the predictors and provides more accurate interpretations of the findings. © 2011 Wiley Periodicals, Inc.  相似文献   

Practical Beauty and the Legacy of Pragmatism: Generating Theory for Community-Engaged Scholarship     

Marie Sandy 《Interchange》2011,42(3):261-285

In this paper I consider how Hans-Georg Gadamer’s philosophical hermeneutics can complement the pragmatic theory that has informed the field of service-learning, and with its emphasis on community and respect for others, can offer an orientation to further the work of service-learning and community engagement in a mutually satisfying way for scholars, practitioners, and community partners. In keeping with Gadamer’s contention that mythological thinking has its rightful place alongside analytical thinking, I provide an interpretation of the myth of Hermes for emancipatory education practice, and then invite readers to consider some implications of philosophical hermeneutics through traditional philosophical exposition. I posit there is much to be gained by framing community engagement as a civic art or practical beauty with a distinct epistemological foundation that values conversation, participation, and openended, collective processes to work for the common good. This orientation would require us to reconsider the purposes and reorient the values of this field of educational practice.  相似文献   

Words on the screen: broadening analyses of interactions among fanfiction writers and reviewers          下载免费PDF全文

Alecia Marie Magnifico  Jen Scott Curwood  Jayne C. Lammers 《Literacy》2015,49(3):158-166

Young fanfiction writers use the Internet to build networks of reading, writing and editing – literacy practices that are highly valued in schools, universities and workplaces. While prior research shows that online spaces frame multiple kinds of participation as legitimate, much of this work focuses on the extensive contributions of exceptional young authors. In this paper, we foreground the contributions of fanfiction reviewers and focus on their interactions with writers, exploring their communicative literacy practices and hypothesising about how we can make their reading and writing more visible and more effectively consider their learning practices. To do so, we conducted a linguistic analysis of fanfiction review comments on two sites, FanFiction.net and Figment.com. While fanfiction readers provide writers with an authentic audience for their creative work, our findings indicate that the review comments that they leave generally do not offer specific feedback regarding the craft of writing. For this reason, we argue that teachers' expertise is still needed in the difficult task of developing young adults' composition, peer review and critique skills.  相似文献   

Orthographic learning during reading: the role of whole‐word visual processing          下载免费PDF全文

Marie‐line Bosse  Nathalie Chaves  Pierre Largy  Sylviane Valdois 《Journal of Research in Reading》2015,38(2):141-158

The self‐teaching hypothesis suggests that knowledge about the orthographic structure of words is acquired incidentally during reading through phonological recoding. The current study assessed whether visual processing skills during reading further contribute to orthographic learning. French children were asked to read pseudowords. The whole pseudoword letter string was available at once for half of the targets while the pseudoword's sub‐lexical units were discovered in turn for the other half. Then memorisation of the targets’ orthographic form was assessed. Although most pseudowords were accurately decoded, target orthographic forms were recognised more often when the pseudowords entire orthographic sequence was available at once during the learning phase. The whole‐word presentation effect was significant and stable from third to fifth grades. This effect was affected neither by target reading accuracy nor by target reading speed during the learning phase. Results suggest that beyond recoding skills, the ability to process the entire orthographic letter string at once during reading contributes to efficient orthographic learning.  相似文献   

The IFLA Trend Report: Looking Beyond the Walls in Library Planning     

Lynne Marie Rudasill 《图书馆管理杂志》2015,55(2):153-164

Strategic planning requires us to stop and take a closer look at our organizations and consider the impact that changes in the profession are causing, influenced by the society around us. These considerations lead us past our library walls, past our institutional walls and into a more speculative world of changes in the technological society. Scholars and pundits have provided us with many scenarios for the future, including a world of solely electronic resources and hyper-connected users. But how closely does this match reality and what are the trends in our larger society that will affect how we work in the future. This article provides an overview of several reports on the students and technologies that we work with and closely explores the IFLA Trend Report. The report was developed after discussions with individuals representing many non-academic, non-library organizations and provides us with a view of the larger trends forecast for the information society. The report is envisioned as a living document that invites further comment and wider distribution to the library world and beyond.  相似文献   

Communicating aims and learning goals in physical education: part of a subject for learning?     

Karin Redelius  Mikael Quennerstedt  Marie Öhman 《Sport, Education and Society》2015,20(5):641-655

Based on a socio-cultural perspective on learning, the aim of this article is to examine how aims and learning goals are communicated in physical education (PE) practice. A special focus is on scrutinising how teaching practices are framed in terms of whether and how the aims and learning goals are made explicit or not to students. The aim is also to relate these kinds of communications to different movement cultures. The result shows that many of the students taking part in the study do not understand what they are supposed to learn in PE. However, if the goals are well articulated by teachers, the students are more likely to both understand and be aware of the learning outcomes and what to learn in PE. The opposite is also true. If the goals and objectives are not clarified, students find it difficult to state the learning objectives and know what they are supposed to learn.  相似文献
