PISA presents a new image for academic achievement, which has prompted Japanese education reforms over the past decade to innovate teaching and learning for ‘PISA-style literacy’. Supported by theoretical foundations, particularly with regard to the concept of ‘PISA literacy’ and ‘authentic assessment’, these reforms have accomplished progress in the focus on higher order competencies, such as application and the development of new assessment strategies. However, more recently, various critical discussions of ‘PISA literacy’ are underway in the Japanese academy. They interrogate it more critically and reveal the narrow emphasis on functional application and technical operation. Current assessment practices, which tend to fall into ‘criteria compliance’, are in urgent need of review. There is a need to extend the critical discussions in progress to the new assessment strategies. This paper responds to this, by considering the Japanese acceptance of ‘PISA literacy’ and its assessment, discussing the features and limitations. 相似文献

Quality models for online and blended learning (OBL) have mainly been developed in higher education. The literature indicates that these models are often conceptualised from the providers’ perspective. What is important for the quality of OBL from the students’ perspective has recently received increased attention in the literature. Consensus among stakeholders about students’ quality needs is useful to support dialogue between professionals to strategically adopt OBL and to ensure that the needs of students are met. This study aims to validate a quality instrument for OBL, taking a set of 74 quality indicators and analysing them in terms of seven success factors (credibility, accessibility, transparency, flexibility, interactivity, personalisation, productivity). The Delphi method was selected as most suited. Participants from adult education were asked to indicate on a 7-point Likert scale to what extent the indicators add to OBL quality to meet students’ needs. After four Delphi rounds, the participants agreed on definitions of success factors and 30 indicators. The results are useful for institutions, ministries of education and external quality assessment agencies to assess the quality of OBL and can support institutions to implement improvement actions to ensure that the needs of students are met. 相似文献

AbstractSince 2003, the Programme for International Student Assessment (PISA) has included students with special educational needs (SEN), identified as those with functional disabilities, those with cognitive/behavioural/emotional disabilities and those with limited test language proficiency. While the number of countries and included students has increased with each test administration, the percentage of students with SEN remains extremely low. The inclusion of these students is not an intentional PISA design parameter but rather a response to the interaction between the need to maintain strict sampling criteria and country-level educational mandates to include SEN students in standardised testing. Based on the analysis of student participation and performance across four cycles of PISA (2003–2012), this paper examines the challenges that exist in current PISA procedures related to: student sampling, eligibility and identification; assessment methodology; and reporting results. PISA practices, their limitations for scientific inferences and recommendations for design improvements are given. 相似文献

农业生态系统是一个自然—社会经济复合生态系统。农业生态系统是否安全运行和有序调控与人类、社会、经济、环境密切相关。近十年来,伴随着人类对食物安全和自身健康的关切,国际上对农业生态安全问题的研究更加广泛和深入,并成为农业生态学研究的重要领域之一。本文阐述了农业生态安全理论的形成和发展,分析了农业生态安全评价的基本原则和评价内容,并在此基础上探讨了统计学模型、生态承载力方法和生态模型法等生态安全的评价方法。 相似文献

Massive population shift is a current global reality – especially given some of the latest development on European shores; some are calling it a humanitarian crisis. Although the United States (US) receives a large number of immigrants (documented and not) and about 70,000 refugees each year, it is certainly not the only nation to do so. Industrialized nations that receive migrants through immigration policies are typically referred to as “receiving” nations. The article addresses two main questions: (1) how well immigrant students across 17 receiving industrialized nations are doing according to the Programme for International Student Assessment (otherwise known as PISA), and (2) how are educators, immigrant and refugee parents and students experiencing integration in the school context. The education of immigrant and refugee students is a complex global issue that requires better understanding, collaborative attention, and long-term investment of several stakeholders. 相似文献

AbstractPeer assessment has proven to have positive learning outcomes. Importantly, peer assessment is a social process and some claim that the use of anonymity might have advantages. However, the findings have not always been in the same direction. Our aims were: (a) to review the effects of using anonymity in peer assessment on performance, peer feedback content, peer grading accuracy, social effects and students’ perspective on peer assessment; and (b) to investigate the effects of four moderating variables (educational level, peer grading, assessment aids, direction of anonymity) in relation to anonymity. A literature search was conducted including five different terms related to peer assessment (e.g., peer feedback) and anonymity. Fourteen studies that used a control group or a within group design were found. The narrative review revealed that anonymous peer assessment seems to provide advantages for students’ perceptions about the learning value of peer assessment, delivering more critical peer feedback, increased self-perceived social effects, a slight tendency for more performance, especially in higher education and with less peer assessment aids. Some conclusions are that: (a) when implementing anonymity in peer assessment the instructional context and goals need to be considered, (b) existent empirical research is still limited, and (c) future research should employ stronger and more complex research designs. 相似文献
