Children’s sense of agency in preschool: a sociocultural investigation     

Jaakko Hilppö  Lasse Lipponen  Kristiina Kumpulainen  Anna Rainio 《International Journal of Early Years Education》2016,24(2):157-171

This socioculturally informed study investigated children’s sense of agency in relation to their everyday life in preschool. The empirical data comprised focus groups reflection situations wherein Finnish preschool children (n. 19, aged 6–7) reflected on their everyday life with the help of photographs and drawings they made. Building on a situative and discursive take on the sense of agency, the results of this study highlight the different forms of the sense of agency talked into being in the focus groups. The results also provide evidence of the different activities within which children’s sense of agency was embedded. In addition, the study also engages with the notion of radical passivity to theoretically explore the borders of the concept of the sense of agency. In all, the study demonstrates the mundane side of children’s sense of agency and its subtle dynamics in day-to-day life in preschool.  相似文献   

论汉语的偏旁和部首     

廖志林 《金华职业技术学院学报》2001,1(2):74-75

现代汉语教本及丛书对汉字偏旁和部首的解释是明晰的，但对什么样的字可作偏旁分析、偏旁和部首之间具有什么样的关系这两个问题，很少有详尽明了的阐述。本文就此作了较为具体的分析，对理解、掌握和使用汉字有一定的帮助。  相似文献

C_2(a~3Π_u)自由基与C_2H_6反应的动力学计算     

薛月圆  李战学 《洛阳师范学院学报》2012,31(8):42-45

用密度泛函理论B3LYP方法,在6-311G(d,p)基组下,优化得到C2(a3Πu)+C2H6→C2H+C2H5反应各驻点(反应物、过渡态和产物)的几何构型,对其进行振动分析,并计算了它们的能量.在CCSD/6-311G(d,p)水平下单点能计算得到的反应势垒为24.47kJ/mol.采用传统过渡态理论,计算了温度范围50K～2000K的反应速率常数.实验结果表明,随着反应温度的升高,反应速率逐渐升高,反应的平均活化能也随着温度的不断升高而不断增大.  相似文献

“Fleeting pockets of anarchy”: Streetwork. The exploding school     

Catherine Burke 《Paedagogica Historica: International Journal of the History of Education》2014,50(4):433-442

Colin Ward (1924–2010) was an anarchist and educator who, together with Anthony Fyson, was employed as education officer for the Town and Country Planning Association in the UK during the 1970s. He is best known for his two books about childhood, The Child in the City (1978) and The Child in the Country (1988). The book he co-authored with Fyson, Streetwork. The Exploding School (1973), is discussed in this article as illustrating in practical and theoretical terms Ward’s appreciation of the school as a potential site for extraordinary radical change in relations between pupils and teachers and schools and their localities. The article explores the book alongside the Bulletin of Environmental Education, which Ward edited throughout the 1970s. It argues that the literary and visual images employed in the book and the bulletins contributed to the powerful positive representation of the school as a site of potential radical social change. Finally, it suggests that “fleeting pockets of anarchy” continue to exist in the lives of children through social networking and virtual environments that continue to offer pedagogical possibilities for the imaginative pedagogue.  相似文献   

Militant Distribution: Votes for Women and the public sphere     

Maria Dicenzo 《Media History》2013,19(2):115-128

The late nineteenth century American mass circulation press developed a style of ‘new journalism’ that gave rise to celebrity journalism. It is widely accepted that this new approach to reporting replaced news values with entertainment as a consequence of the need to cater to the tastes of a mass readership and this is seen to explain the incredible innovations that occurred in the press in the US at the time (Ponce de Leon; Roggenkamp; Tebbel; Turner; Schudson Discovering the News). This article questions this version of American press history by arguing that those papers also had to appeal to the politics of poor immigrants and the working class and that the conventions associated with celebrity overlapped and often coincided with a ‘radical’ populist campaigning style of reporting that was as important (and at times, more important) to building and sustaining mass readerships.  相似文献   

THE ‘RADICAL’ NARRATIVE,POLITICAL THOUGHT AND PRAXIS     

John Steel 《Media History》2013,19(2):221-237

This article offers a methodological refinement to the radical narrative of media history and advocates an exploration of the ideological dynamics of media texts as a crucial component of their praxis. Focusing on early to mid nineteenth-century utilitarian theory and praxis as exemplified in newspapers and pamphlets such as the Westminster Review, the Examiner and Pamphlets for the People, the article offers a sophisticated ideological critique which is intended to augment radical analyses of media history. This analysis allows a more focused and precise account of the ways in which early proto-liberal reformers used the press in their political strategy. Despite the Philosophic Radicals Mill, John S. 1873. Autobiography, London: Longmans, Green and Dyer.  [Google Scholar] having democratic aspirations, the article identifies inherent paternalistic and oppressive components of this praxis which has their seeds in classical Greek political thought.  相似文献   

The didactics tradition in South Africa: a reply to Richard Krüger     

Lesley Le Grange 《课程研究杂志》2013,45(3):399-407

There has been a growing interest in the European Didaktik tradition as part of a process of ‘internationalizing’ curriculum studies. Krüger provides useful insights into some aspects of Didaktiek in South Africa. However, the essay does not contextualize this tradition within the broader history of South African education. This reply contends that Didaktiek was interwoven with ‘fundamental pedagogics’ and as a consequence played a role in reproducing apartheid ideology—it did not provide a language of critique or possibility. This is one reason why the tradition has seen its demise in post‐apartheid South Africa. I argue that curriculum theory, which crucially deals with the relationship between schooling and society and highlights the socially constructed nature of schooling, offers a more useful alternative for critiquing apartheid education policy and for charting a process of transformation of education in South Africa.  相似文献
