This editorial paper presents 11 papers related to the special issue proposed by UNICEF on the Education Response to COVID-19. The COVID-19 pandemic provoked an education emergency of unprecedented scale. At its onset in February 2020, school closures were announced in the worst-hit countries. At the peak of the crisis, 90 per cent of learners worldwide had had their education disrupted. Some learners, especially those from the most marginalised population groups, were put at risk of permanent dropout, provoking long-term and significant negative effects on children’s life-long wellbeing and the socio-economic development of their communities and countries. This special issue, which received contributions from UNICEF staff and various researchers, focuses on the impact of school closures, the effectiveness of remote learning solutions, equity implications, the mitigation of learning loss and notions around re-opening better. Different research perspectives and evidence is gathered to help strengthen policy considerations and future planning. The conclusion emphasizes building on the innovative solutions generated by the response to the crisis to make education systems more resilient, whilst also reinforcing the focus on equity and inclusion so that pre-existing disparities are not exacerbated in the future. 相似文献

The article documents findings from a pilot study undertaken in 2012–2013 in a special needs secondary school in the England, that trialled the use of a multimedia advocacy tool, “The RIX Wiki”. The trial was part of the pathfinder programme, which aimed to reform existing Special Education Needs provision, from the system of statementing to one of developing education health care plans. The reforms became enshrined in the Children and Families Act (2014). The findings were overall positive and helped with person-centred planning processes. The discussion is framed within current and future policy directives. We argue that multimedia advocacy approaches and software tools, like the “RIX Wiki” will have a continued role to play in ensuring the needs, aspirations and choices of children and young people with learning disabilities remain central. 相似文献

This study compares the ideas of social equity in the liberal Anglo-American and Chinese political cultures and seeks potential hybridisations. Through a conceptual examination of scholarly works, this study identifies differences and similarities of social equity between the two political cultures. A common conceptual bridge, deriving from the comparison and hybridisation, is further developed for the discussion of social equity and equity in higher education across the two cultures. The common bridge consists of four constitutes of social equity: political and civil equality, social and economic equality, equality of opportunity and equality of potential and freedom to achieve, the last of which is new hybridity of the two political cultures. This study argues that the hybridity – equality of potential and freedom to achieve – is enlightening to the discussion of equity in higher education as well as social equity across contexts. 相似文献

The COVID-19 outbreak has had a profound impact on education worldwide. As a result of the educational institutions closures, it is likely that the impact on special education would be more detrimental since special education population becomes more vulnerable in the aftermath of an outbreak. In the scope of this study, a researcher created survey was used to examine educators’ teaching experiences and their perceptions about the impact of COVID-19 outbreak on special education students. The sample included 215 educators working in the Special Education and Rehabilitation Centers (SERCs) in Turkey. Results indicated that a large majority of the SERCs were not able to continue their education during the COVID-19 outbreak. In addition, there was a difference in educators’ experiences by their educational practices (normal weekly schedule, reduced schedule, most of the educational activities are suspended, and all of the educational activities are suspended). Perceived level of COVID-19 outbreak impact on special education students were found to be significantly higher for autism spectrum disorders, intellectual disabilities, attention deficit and hyperactivity disorders, visual impairments, hearing impairments, specific learning disabilities and gifted students, respectively. The conclusion highlights the need of global collaboration, disaster preparation and management for students with special needs. 相似文献

Creating and disseminating knowledge through research and teaching has long been regarded as the hallmark of the modern university. However, new university business models have called into question the ‘bundling’ of teaching and research, and sustained research on the relationship between teaching and research has found little evidence of an insoluble connection between the two activities. In this article, we explore the relationship between teaching and research from the perspective of universities’ institutional discourse. We use corpus-assisted discourse analysis to examine the relationship between research and teaching as presented in two sets of institutional texts currently influential in UK Higher Education: Research Excellence Framework environment statements and Teaching Excellence Framework provider submissions (a total of 2143 documents and 12,492,071 words). Our findings show that, while universities emphasise the value of research to their teaching, they do not always emphasise (or sometimes even decry) the influence of teaching on their research. We empirically evidence that, according to what universities themselves write in institutional texts, teaching and research are not always in a mutually beneficial entanglement, but often rather a one-way relationship in which research expertise and institutional prestige are used to bolster claims of teaching excellence. This has implications for the communication of both the vision and the purpose of a university in regulatory exercises and wider policy, but also speaks to the broader idea and practice of being a university in the twenty-first century. 相似文献

Nowadays assuring that search and recommendation systems are fair and do not apply discrimination among any kind of population has become of paramount importance. This is also highlighted by some of the sustainable development goals proposed by the United Nations. Those systems typically rely on machine learning algorithms that solve the classification task. Although the problem of fairness has been widely addressed in binary classification, unfortunately, the fairness of multi-class classification problem needs to be further investigated lacking well-established solutions. For the aforementioned reasons, in this paper, we present the Debiaser for Multiple Variables (DEMV), an approach able to mitigate unbalanced groups bias (i.e., bias caused by an unequal distribution of instances in the population) in both binary and multi-class classification problems with multiple sensitive variables. The proposed method is compared, under several conditions, with a set of well-established baselines using different categories of classifiers. At first we conduct a specific study to understand which is the best generation strategies and their impact on DEMV’s ability to improve fairness. Then, we evaluate our method on a heterogeneous set of datasets and we show how it overcomes the established algorithms of the literature in the multi-class classification setting and in the binary classification setting when more than two sensitive variables are involved. Finally, based on the conducted experiments, we discuss strengths and weaknesses of our method and of the other baselines. 相似文献

Research indicates that engagement acts as an important precursor for learning, yet sustaining the engagement of pupils with special educational needs can be a challenge for classroom staff. An Active Support staff training package, Interactive Training, has been demonstrated as an effective way of increasing engagement in adults accessing learning disability services. In theory the logic of Active Support Interactive Training could extend to a school environment, with the aim of achieving similar outcomes. The current study evaluated a special school-adapted version of Active Support Interactive Training with the aim of increasing engagement in pupils during group-based learning. Findings showed an increase in engagement in pupils for all three settings (classrooms) immediately after intervention, which continued to either increase or stabilise at three-month follow-up. Further research could test the engagement behaviour of staff pre- and post- training intervention and explore practice leadership within the school leadership team to address maintenance. 相似文献

Qualitative investigations into maternal worries during pregnancy are limited. The aim of this study was to identify the content of women''s pregnancy-related worries by completing a content analysis of posts on Reddit. A total of 217 posts by 196 unique users were analyzed. Most worries related to infant factors (32.6%), individual factors (27.1%), and antenatal care factors, such as medical procedures (25.2%). The remaining worries related to situational factors (10.9%) and the partner relationship (4.3%). Although most fears related to fetal well-being, other concerns included problems with family members, women''s own mental health, and not being a “good mother.” These findings support calls for antenatal education to more adequately address women''s psychosocial concerns. 相似文献
