Blending versus whole word approaches in first grade remedial reading: Short-term and delayed effects on reading and spelling words     

O'Connor  Rollanda E.  Padeliadu  Susana 《Reading and writing》2000,13(1-2):159-182

Twelve very poor readers in May of first grade, including four withdisabilities, were randomly assigned to one of two daily tutoring conditions designed to teach children to read regularly spelled short words by one of two methods: blending sounds to form words, or cumulative introduction of whole words. Both treatments included letter/sound correspondences and spelling words in the reading set. At the end of ten sessions, no differences were found between the treatment outcomes; however, delayed posttests one week later found differences favoring the blending treatment on reading and spelling instructional words, and on transfer to words composed of known letter sounds.  相似文献   

加拿大政府与印第安土著民族关系探析   总被引：1，自引：0，他引：1  

王红艳 《辽宁师范大学学报(社会科学版)》2000,(2)

加拿大政府与印第安土著民族之间的关系尚未理顺。加拿大政府与印第安土著民族关系的恶化 ,是由欧洲殖民者对印第安土著人推行的压迫、同化等政策造成的。加拿大政府对印第安人实施的政策有 3个演变过程 :1.绥靖 (与武力交替使用 ) ;2 .统治 ;3.同化。加拿大政府与印第安人在能源与其他自然资源开发 ,印第安人的高犯罪率、高自杀率、高失业率 ,印第安人的自治问题等方面存在着程度不同的矛盾。解决加政府与印第安土著民族的核心问题是恢复印第安等土著民族所固有的自治权等  相似文献   

Special Needs,Cheerful Habits: Smoking and the Great War in Britain, 1914–18     

Michael Reeve 《Cultural and Social History》2016,13(4):483-501

This article applies an interpretive anthropological and phenomenological approach to the Great War in Britain, 1914–18, focusing on the cigarette as a cultural artefact and material commodity, and smoking as a cultural motif and social practice. The primary material featured includes personal correspondence from soldiers and civilians, newspaper articles, advertising and fictional literature. The fundamental task carried out by this study is the connection of developments in technology and distribution accelerated by the Great War, with smoking as a practice bound up with the social, cultural and material conditions in which those on the front found themselves.  相似文献   

Middle-Class Fathers,Sons and Military Service in England, 1914–1918     

Laura Ugolini 《Cultural and Social History》2016,13(3):357-375

The figure of the hyper-patriotic middle-class father, happy to sacrifice his sons to the war, while remaining snug at home, was a recurrent feature of post-First World War literature. This article places this view of wartime fatherhood under scrutiny, suggesting that middle-class fathers with sons of military age rarely behaved as straightforward enforcers of the state’s call to arms. Alongside expressions of vocal pride in sons who conformed to the manly ideal by volunteering, there were resistance, silence and fear, while support for sons who sought to avoid enlistment was a good deal more evident than any determination that sons should do their ‘bit’ at all costs.  相似文献

At a first glance – How reliable and valid is the thin slices technique to assess instructional quality?     

《Learning and Instruction》2021

Various approaches of assessing instructional quality have emerged in educational research. In this article, we present two studies that apply the thin slices procedure, investigating the reliability and validity of the ratings of three dimensions of instructional quality based solely on the first impressions of untrained social observers. Thirty undergraduate students rated 30-s clips from English lessons (Study 1) and Math lessons (Study 2) regarding three quality dimensions. The findings suggest high reliability in these ratings. Multilevel confirmatory analyses suggested construct validity in terms of differentiation between the three dimensions of instructional quality. Finally, we found some overlap between the thin slices ratings of classroom management and constructive support with ratings of trained raters based on observations of full lessons, as well as students’ ratings of these dimensions. We discuss these results with respect to the potential of first impressions of untrained observers to measure instructional quality.  相似文献   

Bad feelings,feeling bad: the affects of Asian-Indigenous coalition     

Gage Karahkwí:io Diabo 《Inter-Asia Cultural Studies》2019,20(2):257-270

ABSTRACT

This article theorizes the affective forms that Asian-Indigenous alliances might take, using examples from contemporary Canadian film and literature as a cultural testing ground. Building on the efforts of scholars like Rita Wong, Larissa Lai, and Malissa Phung to trace a literary genealogy of Asian-Indigenous relations in Canada, the article first considers the structures of feeling which bolster efforts towards coalition-building between Asian settlers and First Nations. Rather than extending an optimistic or redemptive model, the article suggests that negative affect (or, what Sianne Ngai calls “ugly feelings”) ought to be taken seriously as both an unavoidable presence and a potential catalyst in and for active solidarity. The article then analyzes Sto:lo author Lee Maracle’s short story “Yin Chin” and Peter Blow’s documentary film A Village of Widows with an eye towards how bad feelings underpin the narrative calls to action in both texts. The article concludes by considering the role that bad feeling can and does play in terms of inter-referencing practices among cultural and historical scholars.  相似文献
