In 2007, Environmental Education Research dedicated a special issue to childhood and environmental education. This paper makes a case for ‘early childhood’ to also be in the discussions. Here, I am referring to early childhood as the before‐school years, focusing on educational settings such as childcare centres and kindergartens. This sector is one of the research ‘holes’ that Reid and Scott ask the environmental education community to have the ‘courage to discuss’. This paper draws on a survey of Australian and international research journals in environmental education and early childhood education seeking studies at their intersection. Few were found. Some studies explored young children’s relationships with nature (education in the environment). A smaller number discussed young children’s understandings of environmental topics (education about the environment). Hardly any centred on young children as agents of change (education for the environment). At a time when there is a growing literature showing that early investments in human capital offer substantial returns to individuals and communities and have a far‐reaching effect – and when early childhood educators are beginning to engage with sustainability – it is vital that our field responds. This paper calls for urgent action – especially for research – to address the gap. 相似文献

How do students think about algebra? Here we consider a theoretical framework which builds from natural human functioning in terms of embodiment – perceiving the world, acting on it and reflecting on the effect of the actions – to shift to the use of symbolism to solve linear equations. In the main, the students involved in this study do not encapsulate algebraic expressions from process to object, they do not solve ‘evaluation equations’ such as \( 3x + 2 = 8 \) by ‘undoing’ the operations on the left, they do not find such equations easier to solve than \( 3x - 1 = 3 + x \) , and they do not use general principles of ‘do the same thing to both sides.’ Instead they build their own ways of working based on the embodied actions they perform on the symbols, mentally picking them up and moving them around, with the added ‘magic’ of rules such as ‘change sides, change signs.’ We consider the need for a theoretical framework that includes both embodiment and process-object encapsulation of symbolism and the need for communication of theoretical insights to address the practical problems of teachers and students. 相似文献

Advocates of teacher value-added modelling (VAM) argue that this technique can provide evidence on teacher effectiveness to inform teacher policies and broader education system reforms. Critics contend that value-added is a poor proxy for teacher quality and as such is of questionable utility, especially where teacher accountability is concerned. In low- and middle-income countries, and especially sub-Saharan Africa, where the challenge of the ‘learning crisis’ is most severe, a lack of longitudinal data has precluded extensive debate on the matter. In this paper we explore the potential of value-added analysis for diagnostic purposes in the context of Ethiopia. We make use of data from the Young Lives longitudinal study – specifically two rounds of school surveys conducted in Ethiopia between 2012 and 2017 when pupils were in grades 4–8. Learning levels in the Young Lives sites in Ethiopia are very considerably below curricular expectations. Like many countries in sub-Saharan Africa, Ethiopia faces a significant challenge in terms of a ‘learning crisis’ and in terms of the attendant need to develop policies to improve educational effectiveness within the confines of very limited resources. We discuss the background to VAM models and their use, including in relation to the context of Ethiopia. The paper shows that learning progress in primary schools varies widely between classrooms, and between pupils within the same classroom. Some schools and teachers are more successful in raising overall attainment by ‘raising the floor’ of learning and narrowing the dispersion. Others are more successful by ‘raising the roof’. Less effective teachers appear to be particularly ineffective for pupils with higher scores at the start of the year. In contrast, the most effective teachers showed high levels of ‘value-added’ for pupils at all levels of prior performance. Diagnostic analysis of teacher value-added has potential, we argue, to aid understanding of contributors to low levels of learning such as: (i) over-ambitious curricula; (ii) absence of ‘teaching at the right level’; (iii) within class heterogeneity and pupil grouping strategies; and (iv) teaching and learning strategies – such as ‘differentiation’ or ‘mastery’. 相似文献

With this paper, our main aim is to contribute to the realisation of the chemical reactivity concept, tracing the historical evolution of the concept of chemical affinity that eventually supported the concept of chemical equilibrium. We will concentrate on searching for the theoretical grounds of three key chemical equilibrium ideas: ?incomplete reaction’, ?reversibility’ and ?dynamics’. In addition, the paper aims to promote teachers’ philosophical/historical chemical knowledge. The starting point of this historical reconstruction will be the state of the art in the construction of the first affinity tables, based on the concept of elective affinities, during the 18th century. Berthollet reworked this idea, considering that the amount of the substances involved in a reaction was a key factor accounting for the chemical forces. Guldberg and Waage attempted to measure those forces, formulating the first affinity mathematical equations. Afterwards, the first ideas providing a molecular interpretation of the macroscopic properties of equilibrium reactions are presented. Eventually, theoretical chemists integrated previous findings into a new field: thermodynamics. This historical approach may serve as a base for an appropriate sequencing of the teaching and learning of chemical equilibrium. Hence, this paper tries to go beyond the simple development of teachers’ conceptions of the nature of chemistry, for it gives suggestions about how teachers may translate such understandings into classroom practice. 相似文献

ABSTRACTStudents as Partners (SAP) initiatives are often framed as opportunities to reanimate university education so that students become active participants in their learning, and change agents capable of transforming their institutions. Embedded in these framings is a view that students are also the primary ‘experts’ of their learning experiences. This shift marks curious terrain about how staff come into partnership when students are encouraged to understand themselves as experts at the very same time the purpose of universities is beset with multiple and contradictory narratives, and the whole notion of expertise – even for academics – has become unsettled by the politics of a post-truth era. If the advocacy of student expertise is to be understood as a radical intervention to the marketised neoliberal university, as is often claimed, we argue that the desire for expertise has a more compelling basis when students are engaged with what Gina Hunter calls learning to ‘see institutionally’. In this article, we both describe, and put to work, Jeffrey J. Williams’s idea ‘teach the university’ as one mechanism for students and staff working in partnership to ‘see institutionally’. We then examine the nascent efforts of our own SAP initiatives to make a case for why ‘the university’ – as idea and institution – deserves to be introduced to, studied and critically interrogated by students as part of a long tradition of inquiry. While a good many SAP initiatives aim to address where students are absent, under-represented or disempowered in the university, very few appear to take seriously that there is a field of scholarship about universities that lends credibility and contest to the notion of expertise. By staging a conceptual encounter between Williams, Hunter and our own partnership work, the potential for SAP is expanded as project that cares for the future university. 相似文献

In 1970, Joseph Schwab published the first of four papers that argued for a turn to the idea of the Practical in curriculum research and practice. In this paper, I revisit Schwab’s original paper and explore the extent to which his case for the Practical is still relevant today. I first look at the past of the deliberative tradition in which Schwab’s argument is located. I argue that a more precise engagement with the work of Aristotle – particularly the distinction between making/production and doing, and between knowledge of the eternal and of the variable – can strengthen Schwab’s case and allow for a better understanding of the kind of knowledge and judgement needed in education. In relation to the present, I highlight three ways in which the current context has changed from when Schwab published his paper. These concern the strongly diminished space for teachers’ professional judgement; the rise of a call for evidence-based education; and the shift in curriculum studies away from practical questions. To (re)connect the field of curriculum studies and research with questions about the ‘doing’ of curriculum is, in my view, where a deliberative approach such as the one articulated by Schwab remains highly relevant. 相似文献

This paper examines Donald Schön’s critique of Herbert Simon’s ‘science of design’ to determine whether later developments in Simon’s thought – particularly, his theories of ‘bounded rationality’ and ‘goal-less designing’ – can contribute to an appreciation of Schön’s notion of reflective practice. The paper then argues, that viewed through the optic of ‘assessment for learning,’ teaching may be conceived as ‘goal-less and reflective design,’ and the practice thereof may lead to more effective teaching. 相似文献

The purpose of this study was to compare the effects of a conceptual change approach over traditional instruction on tenth‐grade students’ conceptual achievement in understanding chemical equilibrium. The study was conducted in two classes of the same teacher with participation of a total of 44 tenth‐grade students. In this study, a pre‐test/post‐test control group semi‐experimental design pattern was used. During teaching the topic of chemical equilibrium concepts in the chemistry curriculum, a conceptual change approach was applied in the experimental group whereas traditional instruction was followed in the control group. Data were analysed with an independent samples t‐test, and an analysis of covariance using the pre‐test scores as the covariate. The results showed that the conceptual change approach was statistically more effective than traditional instruction in terms of students’ conceptual understanding. After the six‐week intervention, interviews were conducted with 18 selected students in the study. In the interviews a prevailing alternative conception was detected beside many alternative conceptions. When they were asked to compare equilibrium constants of two different reactions they mostly responded to mean that ‘the bigger the mol number of the products, the bigger the equilibrium constant’ without considering what proportions the reactants were transformed into products in a reaction. Also, in this study a two‐tier multiple choice test was developed related to chemical equilibrium to detect students’ concepts and alternative concepts. 相似文献

This paper looks at the ways in which the gendered social construction of the ‘popular girl’ infuses girls’ ideas as to their role models: those representing who they would like to be when they ‘grow up’. It will look at the ways in which the gendered characteristics that are seen to be of most value to girls (often embodied by ‘celebrities’ such as Britney and Beyoncé) often reflect socially dominant constructions of femininity. These characteristics can in some ways be seen to emphasise passivity rather than agency and power – for an example in an emphasis on attractiveness and appearance rather than activity and accomplishments. However, such desired characteristics are also those considered to characterise the ‘popular’ girl at school – a position of power and influence amongst girls’ peers. Therefore such desires are complexly located within both the constraints of hegemonic femininities and the dynamics of power relations between girls themselves. 相似文献

This article explores the relationship between philanthropy and education in the context of eighteenth‐century Protestant Dissent. More particularly, it examines the intersection between philanthropy, fund‐raising and educational administration as they evolved within the institutional lifecycle of the collegiate Dissenting academies. It argues that individual academies experienced at least three of four life stages, each of which had its own unique challenges. All academies went through the first two of these stages, namely ‘foundation’ and ‘maintenance’. Whether or not an academy experienced the last two stages – ‘transition’ and ‘dissolution’ – depended on factors such as the financial strength of an academy and the reliability of its principal supporters. To illustrate these stages and their philanthropic subtexts, the article focuses on three institutional ‘traditions’, those of the Northampton Academy and its successors, the Warrington Academy, and Trevecca College and its successor Cheshunt College. 相似文献

This paper reports on 6–11-year-old children’s ‘sayings and doings’ (Harré 2002) as they explore molecule artefacts in dialectical-interactive teaching interviews (Fleer, Cultural Studies of Science Education 3:781–786, 2008; Hedegaard et al. 2008). This sociocultural study was designed to explore children’s everyday awareness of and meaning-making with cultural molecular artefacts. Our everyday world is populated with an ever increasing range of molecular or nanoworld words, symbols, images, and games. What do children today say about these artefacts that are used to represent molecular world entities? What are the material and social resources that can influence a child’s everyday and developing scientific ideas about ‘molecules’? How do children interact with these cognitive tools when given expert assistance? What meaning-making is afforded when children are socially and materially assisted in using molecular tools in early chemical and nanoworld thinking? Tool-dependent discursive studies show that provision of cultural artefacts can assist and direct developmental thinking across many domains of science (Schoultz et al., Human Development 44:103–118, 2001; Siegal 2008). Young children’s use of molecular artefacts as cognitive tools has not received much attention to date (Jakab 2009a, b). This study shows 6–11-year-old children expressing everyday ideas of molecular artefacts and raising their own questions about the artefacts. They are seen beginning to domesticate (Erneling 2010) the words, symbols, and images to their own purposes when given the opportunity to interact with such artefacts in supported activity. Discursive analysis supports the notion that using ‘molecules’ as cultural tools can help young children to begin ‘putting on molecular spectacles’ (Kind 2004). Playing with an interactive game (ICT) is shown to be particularly helpful in assisting children’s early meaning-making with representations of molecules, atoms, and their chemical symbols. 相似文献

This paper investigates the ways in which discourses of teacher accountability were negotiated by teachers within hearings held for the Australian Inquiry into Boys' Education. In the Inquiry context, dominant interpretative repertoires positioned teachers as obliged to ‘acknowledge’, ‘address’ and ‘actively respond’ to an essentialised version of male students' ‘learning needs’. These repertoires functioned to equate the provision of ‘boy-friendly’ interventions with ‘professional’ classroom practice – suggesting significant discursive constraints on teachers' capacity to make sense of boys' underperformance outside of this dominant framework. Attention is paid to the ways in which these repertoires supported teachers to manage a positive identity in a context where they were positioned as largely responsible for male students' underperformance. At the same time, such constructions are interrogated with regard to their broader function in naturalising the surveillance of teachers, and reproducing boys' underachievement as something for which (particularly female) teachers have to account. 相似文献

This article presents an argument for re-reading Jean Baudrillard’s ideas considering their potential contribution to the sociology of higher education, particularly in relation to contemporary debates about ‘world-class’ universities. In order to apply Baudrillard’s ideas, China’s commitment to the development of ‘world-class’ universities is presented as a case study. Radical thinking, as understood by Baudrillard, relies on ambivalence and fascination – instead of critique – and seeks to push a logic to its limits rather than opposing it. Critiques of world-class universities have not stopped the totalizing effects of rankings and world-class status seeking; on the contrary, these phenomena and their effects continue to accelerate. A non-deterministic approach to thinking is set into motion around the paroxystic state that prevails in the pursuit of ‘world-class’ status among contemporary higher education systems. 相似文献

Insufficient attention has been given to the role of cultural differences in feedback communication with the UK’s increasingly internationalised student body. This issue is particularly significant for international students taking short – one-year – postgraduate taught courses and we illustrate this in a study of Chinese students at a UK university. We draw on Holliday’s notion of ‘small cultures’ and Berry’s model of cultural adaptation to analyse how they perceive, react to and gradually adapt to the provision of formative feedback as a key aspect of the new academic culture. Our data reveal that such feedback presents the students with cognitive challenges and psychological and emotional struggles, especially in the early months of their courses. Avoiding culturally essentialist explanations for this, we focus on differences in the ‘small cultures’ of academia in China and the UK. Feedback is not only a part of the new academic culture itself, but can act as a bridge between norms, rules and practices of the two cultures. This bridge is often poorly constructed. Tutors need to be more aware of the nature and sources of stress that such students face and to which feedback may often be adding rather than contributing to enhanced learning. 相似文献

A chemical reaction is usually thought of as coming together of reactant molecules to form products. The concentrations of
initial components (reactants) decrease, and concentrations of products increase until they reach a well defined state: the
equilibrium. This process is accompanied by a decrease of the system free energy (compared at constant pressure and temperature),
until it reaches a minimum in the equilibrium. Thus, it follows from the nature of the law of mass-action that every simple
reaction approaches its equilibrium asymptotically, and the evolution of any physico-chemical system leads invariably to the
steady state of maximum disorder in the universe. Normally, chemical systems approach equilibrium in a smooth, frequently
exponential relaxation. Under special circumstances, however, coherent behavior such as sustained oscillations are observed
and the oscillations of chemical origin have been present as long as life itself. Such reactions can be studied using mathematical
models, the Lotka-Volterra model being the earliest and the simplest one. 相似文献

ABSTRACTThe word ‘humanities’ does not appear in the current Northern Ireland Curriculum (NIC). Geography and history are taught within an Area of Learning called ‘The World Around Us’ which also contains science and technology. The curriculum has a strong emphasis on an integrated, ‘connected learning’ way of teaching and learning. Religious Education is a separate subject that stands alongside, rather than within, the NIC, and the curriculum also includes a new Area of Learning – ‘Personal Development and Mutual Understanding’. The distinctive content and modes of teaching which the humanities subjects tend to encourage ought to be seen as particularly important in Northern Ireland – a part of the UK which has endured a complicated past and remains to a large extent segregated, both socially and educationally. This complicated past means that there is often wariness and reluctance on the part of teachers towards tackling controversial personal and social issues in the primary school. 相似文献

AbstractAbstractThis paper contributes to the conceptual and empirical development of ‘preparedness pedagogy’. Preparedness involves learning, thus disaster risk reduction (DRR) should be discussed more in the field of education, particularly its sub-discipline of public pedagogy. Disaster risk reduction education should have an element of a pedagogy in the interest of publicness, which is an experimental pedagogy in which citizens act in togetherness to develop their own preparedness. The paper pays attention to the two phrases utilised in the recent DRR discourse – ‘integrated’ DRR and ‘participation by all’ – and examines the case of Japan, applying whole-system thinking. It is suggested that ‘the mesosystem’ of the DRR system yields relationships and learning, and thus enables collaboration, change and ‘participation by all’. Preparedness pedagogy has a role to play in this. The mesosystem functions as the confluence between state-led and community-based DRR to truly integrate the system. 相似文献

‘Language across the curriculum’ has been pivotal in establishing a knowledge base on the role of language for accessing opportunities afforded by the curriculum. Yet, the ubiquity of language within all facets of human activity – not least of all the more abstract domains of thinking and relating with others – can easily obscure its perceptibility as an object for research relative to other priorities; especially when the curriculum focus is directed towards content-oriented areas, such as mathematics or the humanities. This paper uses an ecological framework to consider the place of language when the teacher’s focus is not solely on language, or content, but is equally attentive to both through a relatively new approach to theorizing learners’ non-native language within the curriculum: content and language integrated learning. In particular, it critically examines the notion of ‘integration’ as a pedagogical assumption for working with language in curriculum domains by focusing on teachers’ perceptions of the affordances of language as a meditational tool within the classroom space. Findings raise new implications for understanding the role of language(s) within the curriculum, and are significant for addressing the needs of a changing, globalized student demographic where the presence of multiple languages will increasingly shape learners’ engagement with the curriculum. 相似文献

ABSTRACT In the contemporary literature of educational philosophy and theory, it is almost routinely assumed or claimed that ‘education’ is a ‘contested’ concept: that is, it is held that education is invested – as it were, ‘all the way down’ – with socially constructed interests and values that are liable to diverge in different contexts to the point of mutual opposition. It is also often alleged that post-war analytical philosophers of education such as R. S. Peters failed to appreciate such contestability in seeking a single unified account of the concept of education. Following a brief re-visitation of Peters’ analytical influences and approach and some consideration of recent ‘post-analytical’ criticisms of analytical educational philosophy on precisely this score, it is argued that much of the case for the so-called ‘contestability’ of education rests on a confusion of different concepts with different senses of ‘education’ that proper observance of well-tried methods of conceptual analysis easily enables us to avoid. 相似文献
