This real‐data‐guided simulation study systematically evaluated the decision accuracy of complex decision rules combining multiple tests within different realistic curricula. Specifically, complex decision rules combining conjunctive aspects and compensatory aspects were evaluated. A conjunctive aspect requires a minimum level of performance, whereas a compensatory aspect requires an average level of performance. Simulations were performed to obtain students' true and observed score distributions and to manipulate several factors relevant to a higher education curriculum in practice. The results showed that the decision accuracy depends on the conjunctive (required minimum grade) and compensatory (required grade point average) aspects and their combination. Overall, within a complex compensatory decision rule the false negative rate is lower and the false positive rate higher compared to a conjunctive decision rule. For a conjunctive decision rule the reverse is true. Which rule is more accurate also depends on the average test reliability, average test correlation, and the number of reexaminations. This comparison highlights the importance of evaluating decision accuracy in high‐stake decisions, considering both the specific rule as well as the selected measures.  相似文献   

Transnational Media Management: Western News Organizations’ Web Operations in China     

Hsiang Iris Chyi  James Ian Tennant 《媒体管理杂志》2017,19(4):261-281

In 2008, China surpassed the United States as the largest Internet market in the world. This study examines how four prominent Western news organizations respond to this new era of Internet publishing. A series of in-depth interviews with senior managers at The Wall Street Journal, Financial Times, Reuters, and The New York Times revealed how these news organizations serve Internet users in China through their Chinese-language Web editions—how they overcome geographic, language, cultural, and political barriers to explore this remote market. These cases demonstrate the viability of different operating models and the challenges and opportunities facing these media organizations as they manage transnational news operations in this seemingly lucrative market.  相似文献   

Reception Teacher Responses to the Foundation Stage Réactions des enseignants des premières classes du primaire à la phase de fondation Las Racciones de los Maestros del Primer Año (de un parvulario) respecto a la Etapa Preparatoria

Teachers of children aged four and five years in England (the Foundation Stage), since 2000, have been bound by the Curriculum Guidance produced by central UK Government. We were interested to learn of the responses of these teachers to this newly introduced document. We found that teachers welcomed the Foundation Stage Curriculum Guidance, not least because it recognised that there exists a valuable and separate stage in children's education. Further, the teachers were relieved that there was, within the document, the acknowledgement of the importance and value of play as integral to the educational needs of young children. The teachers indicated that the document was also beneficial in that it allowed them to return openly to what they felt to be sound Early Years practice which some had felt had been undermined by previous curriculum guidance. However, concerns remained in that not all stakeholders are yet aware of the needs of young children and of the resources necessary to meet these needs. En Angleterre, depuis 2000, les enseignants des enfants de quatre et cinq ans (phase dite de 'fondation') doivent se conformer à la Curriculum Guidance (Lignes directrices des programmes scolaires) produite par le gouvernement central du Royaume-Uni. Nous souhaitions connaître les réactions de ces enseignants face à ce nouveau document. Nous avons constaté que les enseignants accueillent favorablement la Foundation Stage Curriculum Guidance tant elle reconnaît l'existence d'une phase utile et distincte d'assimilation chez les enfants. En outre, les enseignants ont été soulagés de constater que la document reconnaît l'importance et l'utilité du jeu comme faisant partie intégrante des besoins éducatifs des jeunes écoliers. Ils ont également fait savoir qu'ils trouvent ce document utile dans la mesure où il leur permet de revenir ouvertement à des pratiques qu'ils considèrent comme étant saines pendant les premières années scolaires des enfants et qui, selon certains, avaient été amoindries par les lignes directrices des programmes scolaires précédents. Ils s'avèrent néanmoins toujours préoccupés du fait que toutes les parties prenantes ne sont pas encore conscientes des besoins des jeunes enfants et des ressources nécessaires pour les satisfaire. Desde el año 2000, en Inglaterra, los profesores de niños de la edad de 4 y 5 años (la Etapa de Fundación) han tenido que conformar con las reglas de curriculum introducidas por el gobierno central del Reino Unido. Tuvimos interes de enterarnos de las respuestas de aquellos profesores a ese documento nuevo. Encontramos que los profesores estan de acuerdo con la 'Guía de Curriculum de la Etapa de Fundación', por lo menos porque reconoció que existe una etapa válida y aparte en la educación de niños. Además estuvieron contentos que el documento reconició la importancia y validez de juegos infántiles imprescindible en el desarrollo del niño. Los profesores indicáron que el documento fue beneficioso también porque les permitió volver abiertamente a lo que sentieron que fueron 'prácticas sanas' de los años primeros que algunos de ellos pensaron que habían estado desacreditadas por las 'Guías de Curriculum' previas. No obstante quedan preocupaciónes que algunos interesados todavía no estan enterados de lo que los niños necesitan y los recursos que hacen falta.  相似文献   

The management and training needs of reception teachers working with the Foundation Stage Curriculum     

Elaine Hodson  Iris Keating 《International Journal of Early Years Education》2007,15(1):67-81

In England, since 2000, teachers of children aged three to five (the Foundation Stage) have been bound by the Curriculum Guidance for the Foundation Stage produced by central government. Initially, we were interested to learn of the responses of early years teachers to that document. We found that teachers welcomed the Curriculum Guidance, not least because it recognized that there exists a valuable and separate stage in children’s education. However, in relation to ensuring that quality learning experiences were provided, teachers identified two issues of concern to them—professional training of early childhood teachers, and the leadership and management of the Foundation Stage. Concerns also remained that not all stakeholders were yet aware of the needs of young children and of the staff training resources necessary to meet these needs. Upon our return to the respondents three years later, we found that, despite the incorporation of the Curriculum Guidance, some practitioners continued to feel that both colleagues and managers sometimes had limited understanding of the unique nature of the early childhood curriculum. Concerns about resources and an appropriate learning environment also continued to be evident.  相似文献   

The role of maternal mediation of writing to kindergartners in promoting literacy in school: A longitudinal perspective     

Aram  Dorit  Levin  Iris 《Reading and writing》2004,17(4):387-409

The current study follows up on Aram andLevin's (2001, Cognitive Development, 16, 831–852)analysis of the role of maternalwriting mediation among low SES Israelikindergartners. That study's main findingindicated that the quality of maternal writingmediation correlated concurrently withkindergartners' literacy skills aftercontrolling for socio-cultural measures. Thepresent study followed up the participants tothe second grade in school, and evaluated theirlevel of Spelling, Reading Comprehension, andLinguistic Knowledge two and a half years later. Theresults indicate that the children's literacymeasures in school were predicted by maternalwriting mediation in kindergarten beyond SESand the early literacy measures assessed in thekindergarten (Word Writing and LinguisticKnowledge). These results highlight thesignificance of early maternal writingmediation as a major factor in literacydevelopment.  相似文献

Situated Learning: Conceptualization and Measurement     

Lakshmi Goel  Norman Johnson  Iris Junglas  Blake Ives 《Decision Sciences Journal of Innovative Education》2010,8(1):215-240

A focus on the interaction between cognitive schemas and context in situ has been suggested as fundamental in organizational decision making and information interpretation. Past research suggests that the situation and the social interaction that occur during learning at the cognitive level consist of factors that affect the process, but the research lacks a coherent explanation for how those factors affect it. We propose a conceptualization of learning, termed situated learning, which accounts for these factors. By drawing on situated cognition theory, social learning theory, and the theory of mental models, we identify and measure four components of situated learning, that is, thematic focus, cognitive absorption, social structure, and participation. Among the most important lessons for researchers and practitioners is the need to consider learning as a constellation of the four components instead of an indivisible phenomenon. This perspective can enhance our understanding of cognitive processes, such as information interpretation and decision making.  相似文献   

Bases of competence: an instrument for self and institutional assessment     

Iris Berdrow  Frederick T. Evers 《Assessment & Evaluation in Higher Education》2010,35(4):419-434

The Bases of Competence model provides a general framework for learner‐centred skill development and programme‐focused outcomes assessment. Based on previous research, the Bases of Competence model describes 17 skills and four base competencies important to graduates to achieve high performance in the workplace. Taking this work from research to relevant educational application as a tool for student self‐assessment and institutional outcomes assessment is the focus of this paper. Results from a multi‐year, multi‐course assessment initiative indicate that students rate themselves stronger in the foundation base competencies of Communicating and Managing Self, and weaker in more complex competencies of Managing People and Tasks and Mobilising Innovation and Change. Comparisons of skill confidence within each base competence as well as between year, student level, gender and beginning versus end of semester are presented as well. These results are discussed and suggestions made for programme design.  相似文献   

School funding formulae: designed to create a learning society?     

Iris BenDavid-Hadar  Stephoni Case  Rob Smith 《Compare》2018,48(4):553-570

The right to education depends upon a willingness to finance education fairly. Addressing the difference in educational achievement between learners of different backgrounds is a key aspect of fairness. Framed by contemporary neoliberal policies around marketisation and competitiveness, this paper examines fairness in the education finance policy (EFP) of three jurisdictions in England, Israel and Oklahoma. Using a comparative analysis of school funding formulae and an international survey on the perceptions of local policy actors, the de jure and the de facto EFPs are examined. Our findings reveal de jure policies attempting to address fairness through integrating different student background characteristics. However, variability is evident in the extent to which the de facto policies align with an aspiration for fairness. This is linked to the marketisation of education in each jurisdiction. We conclude that weightings of students’ background characteristics can only be one feature in policy interventions orientated towards bringing about social equity.  相似文献
