This article explores linguistic-cultural ideologies and educational policies as they emerge and are negotiated in everyday life in a bilingual school setting located in the geopolitical spaces of Sweden. Taking sociocultural theory and discourse analysis as points of departure, we focus on empirical examples of classroom interaction and locally established formal policing. Linguistic-cultural ideologies and educational policies that frame life at the school are investigated by employing nexus analytical methods, focusing on social (inter)actions through which a number of locally and nationally relevant discourses circulate. Our findings indicate that refocusing ideology and policy research from the lens of a practiced perspective allows the situated and distributed nature of everyday life to inform issues related to bilingualism as well as their relations to wider societal discourses. Furthermore, our analysis highlights the crucial role of educators in (re)locating bilingual education in its societal contexts as well as making these connections visible in classrooms. 相似文献

A high circulating concentration of the non proteinogenic amino acid homocysteine has been implicated as a risk factor for Alzheimer’s Disease and its prodromal stage, mild cognitive impairement. Furthermore, hyperhomocysteinaemia has been directly attributed to a deficiency in vitamins B12, folate, and B6. Several studies have demonstrated decrease in progression of mild cognitive impairement to Alzheimer’s Disease, and some have even shown an improvement in cognition after vitamin supplements with B12 and folate. Plausible mechanisms linking hyperhomocysteinaemia to Alzheimer’s and cognitive impairement have been hypothesized and demonstrated in hyperhomocysteinemic mice models. However, some studies have not elucidated any benefit of vitamin supplements in subjects with cognitive impairment. Hence, multicentric clinical studies need to be conducted to substantiate the mechanisms of neuronal degeneration due to hyperhomocysteinaemia and to demonstrate the beneficial effect of folate, B6 and B12 supplements on cognition. 相似文献

In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science. 相似文献

We present here a qualitative test that distinguishes between monosaccharides, reducing disaccharides, non-reducing disaccharides, aldoses and ketoses using alkaline potassium ferricyanide. This is a simple, quick and unambiguous test to distinguish various carbohydrates from one another and is reliable enough to replace other tests reported in standard laboratory textbooks. 相似文献

States currently are in the process of developing child and family outcome measurement systems for young children with disabilities to meet federal data reporting requirements for the Part C (Infants and Toddlers with Disabilities) and Part B Preschool Grants program supported through the Individuals with Disabilities Education Act. This article reviews issues related to the use of assessments in providing outcome data, discusses challenges raised in conducting valid assessments with young children for accountability purposes, and outlines decisions states must make related to assessment as they design and implement outcome measurement approaches. Considerations related to the standardized or curriculum-based measures are discussed along with other choices related to the use of assessment for accountability. 相似文献

The use of digital tools like computers and tablets in institutional learning arenas give rise to forms of flexibility where time and space boundaries become diffuse. Online learning sites are understood as being crucial today, especially in large parts of the Global North, where anyone anywhere potentially can become a student and have access to educational opportunities.This study focuses on the analysis of recorded sessions, part of an ‘Italian for (adult) beginners' online course. Our interests relate to accounting for how students negotiate different language varieties, including modalities, and how communication in virtual learning settings enables both flexible participation trajectories and identity positions in and across the boundaries of time and space.The sociocultural and dialogical analyses here are framed in terms of fluidity of ‘glocal' positions and (trans)languaging that emerge in and across time and space in Technology Mediated Communication. Our findings suggest that online environments support meaning-making where it is possible to identify alternative ways of (co)constructing and mediating learning. Such hybridity as well as the performative character of learning and identity display have important implications for online glocal communities. 相似文献
