美国双语教育的历史演变与政策反思 总被引:1,自引:0,他引:1
美国双语教育近年来引起了我国学者的关注,但是少有学者对此掌握第一手的资料,因而缺乏系统的观点.本文根据笔者对美国双语教育项目的亲身参与,①系统阐述了美国双语教育的历史与现状,并对双语政策的演变进行了反思.笔者认为虽然移民潮、国际环境变化、国内政局交替等因素直接推动了双语教育政策的演变,但是这些外在条件只是起到了催化剂的作用,双语教育争辩的真正根源在于不同的语言取向和语言意识形态. 相似文献

大革命时期,许多中共党人都论述过国民党左右派,谈得最早、最多的是陈独秀。其论断集中体现在对国民党左右派划分标准、代表的阶级利益、队伍构成以及分化等问题。这些认识既包涵着积极成果,也存在着历史局限。 相似文献

This study explores whether critical pedagogy is viable for meeting the goals of the Malaysia Education Blueprint (MEB) 2015–2025. The MEB has a particular focus on societal improvement and the authors suggest that critical pedagogy should be considered as a way of teaching as it specifically aligns with the aims of government policy. However, there is uncertainty about how critical pedagogy might be enacted in the Malaysian higher education context because it is difficult to understand and practise. The authors interviewed English language critical pedagogues from various countries about their experiences and found four common themes across all cultures. These were: co-construction of knowledge between teacher and student; new levels of trust; the use of problem-posing techniques; and evaluation of teaching and the student experience. These findings provide a guide to practice and the authors conclude that for critical pedagogy to gain acceptance across Malaysia, consideration needs to be given to changing prevailing cultural norms, the strict social order, as well as the political landscape of the country. 相似文献

Objective: To assess the effect of angiotensin Ⅱ type 1 (AT1) receptor antagonist losartan on myocardium connexin43 (Cx43) gap junction (GJ) expression in spontaneously hypertensive rats (SHRs) and investigate possible mechanisms. Methods: Sixteen 9-week-old male SHRs and 8 age-matched male Wistar-Kyoto (WKY) rats were included in this study. SHRs were randomly divided into two groups to receive losartan at 30mg/(kg·d) by oral gavage once daily for 8 weeks (SHR-L) or vehicle (0.9% saline) to act as controls (SHR-V); WKY rats receiving vehicle for 8 weeks served as normotensive controls. At the end of the experiment, rats were sacrificed and the hearts were removed. Expressions of Cx43 and nuclear factor-kappaB p65 (NF-κB p65) proteins in all three groups were observed and further investigations on the effect of angiotensin Ⅱ type 1 receptor antagonist losartan (30mg/(kg·d), 8 weeks) on Cx43 expression were conducted with Western blot and immunohistochemistry. NF-κB p65 protein in nuclear extracts was determined by Western blot. Results: Left ventricular (LV) hypertrophy was prominent in SHRs, Cx43 and NF-κB p65 protein expressions were obviously upregulated and Cx43 distribution was dispersed over the cell surface. Treatment with losarton reduced the over-expressions of Cx43 and NF-κB p65 in LV myocardium. The distribution of Cx43 gap junction also became much regular and confined to intercalated disk after losartan treatment. Conclusion: Cx43 level was upregulated in LV myocardium of SHR during early stage of hypertrophy. Angiotensin Ⅱ type l receptor antagonist losartan prevented Cx43 gap junction remodeling in hypertrophied left ventricles, possibly through the NF-κB pathway. 相似文献

本文论述了“左”的错误产生的思想认识根源。文章认为,在我们党的历史上曾多次出现过“左”的错误。这种“左”的错误曾严重地危害革命事业,如不及时防止,它会葬送社会主义事业。“左”的错误思想根源是不能正确认识社会主要矛盾。在社会主义建设时期,“左”的根源在于不能正确认识社会主义时期的主要矛盾。 相似文献

在我党历史上,毛泽东作为党内正确路线的代表,曾与历次“左”倾路线做斗争并受到“左”倾路线的排挤和打击。在他掌控了党的领导权后,坚持了有“左”必纠的方针。但晚年却也犯了严重的“左”的错误。全面地、实事求是地分析造成这一历史悲剧的成因,对于加强党的执政能力建设具有重要的警示作用。 相似文献
