翻转课堂侧重在课外完成知识的学习,在课堂中完成知识的内化。但翻转课堂仅是一种教学组织方式,需配合具体的教学方法才能让翻转课堂“活”起来。WebQuest是一种在网络环境下任务驱动式的探究性学习方式,教师创建学习情境,引导学生利用网络资源以任务驱动进行自主探究活动,并以小组形式展开讨论与思考。将WebQuest与翻转课堂联合应用于信息素养教育,有助于活跃学生思维。  相似文献

ABSTRACT

In a networked society, humans are connected through mobile devices to always-on networks, and these technologies merge with us in new ways. In this environment, studying human-networked interactions involves an expanded type of usability. In this article, we argue that a key component of usability is how humans connect and disconnect from these networks. For this reason, the authors advocate studying how users connect and disconnect between online and offline contexts in their everyday life. Such an effort involves questioning our assumptions about the role of connection in usability and introduces methodological issues in studying these processes. These shifts require our research to be more multidisciplinary and more methodologically demanding, with major implications for the portability and durability of technical communication research.  相似文献

ABSTRACT

This paper explores the challenging situation faced by teachers as professionals and members of the community in Aceh, Indonesia during the province's civil war. It reveals how teachers’ sense of agency during this period was deeply influenced by the economic/material, political and socio-cultural condition at that time – conditions and experiences which today have bearing on a place for teachers in the post-conflict peace-building process occurring in the province. During the conflict, teachers struggled to balance their strategic societal positioning – as civil servants and community members – and found themselves caught in the middle of a complex range of hegemonic and counter-hegemonic forces at play. This position of constraint, we argue, limited the ability of teachers to act as peace-builders during the conflict, and continues to influence teachers’ ability to function in such ways today.  相似文献

The student population across world is increasingly reflective of diverse cultures, religions and ethnicities. This rich diversity may become a challenge for educational leaders, teachers, and policy‐makers in the absence of an understanding of diverse sources of knowledge people draw on for directing their beliefs and daily practices. This paper explores the multi‐ethnic context in Britain with a focus on Muslim students in English secondary schools, and argues for drawing on diverse ethnic knowledge sources to inform and enrich approaches towards managing diversity. It discusses the concept of Adab derived from Muslim ethics and philosophy, and debates possible contributions of such conceptual adaptations towards improving educational engagement and performance.  相似文献

Plexiform lesions (PLs), which are often accompanied by perivascular infiltrates of mononuclear cells, represent the hallmark lesions of pulmonary arteries in humans suffering from severe pulmonary arterial hypertension (PAH). Endothelial progenitor cells (EPCs) have been recently implicated in the formation of PLs in human patients. PLs rarely develop in rodent animal models of PAH but can develop spontaneously in broiler chickens. The aim of the present study was to confirm the presence of EPCs in the PLs in broilers. The immune mechanisms involved in EPC dysfunction were also evaluated. Lungs were collected from commercial broilers at 1 to 4 weeks of age. The right/total ventricle ratios indicated normal pulmonary arterial pressures for all sampled birds. Immunohistochemistry was performed to determine the expressions of EPC markers (CD133 and VEGFR-2) and proangiogenic molecule hepatocyte growth factor (HGF) in the lung samples. An EPC/lymphocyte co-culture system was used to investigate the functional changes of EPCs under the challenge of immune cells. PLs with different cellular composition were detected in the lungs of broilers regardless of age, and they were commonly surrounded by moderate to dense perivascular mononuclear cell infiltrates. Immunohistochemical analyses revealed the presence of CD133+ and VEGFR-2+ cells in PLs. These structures also exhibited a strong expression of HGF. Lymphocyte co-culture enhanced EPC apoptosis and completely blocked HGF-stimulated EPC survival and in vitro tube formation. Taken together, this work provides evidence for the involvement of EPCs in the development of PLs in broilers. It is suggested that the local immune cell infiltrate might serve as a contributor to EPC dysfunction by inducing EPC death and limiting their response to angiogenic stimuli. Broiler chickens may be valuable for investigating reversibility of plexogenic arteriopathy using genemodified inflammation-resistant EPCs.  相似文献
