This paper explores experiences that remained salient in the memories of former participants in three nature-based programs in Colorado, five to forty years after childhood involvement. Interviews with program founders and staff, archival research, and observations of current activities provided an understanding of each program’s history, mission and educational approach. In this context, 18 former participants were interviewed about program experiences that they remembered and program impacts on their environmental identities and academic or career choices. Results were analyzed through the lens of social practice theory, which has significant implications for the design and evaluation of environmental education programs. Results showed that social practice theory is a useful framework for interpreting the development of a social environmental identity, but an ecological identity that forms through direct contact with the natural world is an important complementary concept. 相似文献

In higher education research, theoretical approaches stressing isomorphism dominate the discourse on how higher education institutions ‘behave’ in their higher education and research systems. We argue that research should address both instances of similarity and differences. Using theoretical notions from institutionalism and the branding/marketing literature, and focusing on how UK universities are different and similar in their welcome addresses—as expressions of the institutions’ images—we are able to offer a balanced view of patterns of similarities and differences as well as share findings of patterns over time (2005–2015). Using quantitative and qualitative content analysis, our findings show overall high levels of homogeneity of images across the universities. But younger and less prestigious institutions were (both in 2005 and 2015) more inclined to show distinctive images. 相似文献

ABSTRACTThe overall aim of this study is to explore how individual children with long-term school difficulties follow unique ‘trajectories of participation’ in special educational needs settings, sometimes in unexpected ways, and how this contributes to alternative forms of identification and processes of learning. The data draws on long-term video-ethnographic work, tracing trajectories of participation during the course of a school year for an individual girl with an ADHD diagnosis who is a newcomer to a special support school in Sweden. We use a multi-layered theoretical and methodological framework to learning, identities and participation as situated practices to explore how the focal girl, through her everyday participation in classroom contexts structured to amplify the student’s capabilities, gradually moves from an ‘unwilling student’ to an ‘agentive learner’. Through a multimodal interactional analysis, we demonstrate how the focal girl’s actions and the teacher’s scaffolding responses are interactionally organised, and the emotional and relational dimensions in the creation of participation frameworks for learning. It is argued that the student’s agency and emerging emotional engagement in school-based learning are intimately linked to the pursuit of building long-term learning relationships based on mutual trust. 相似文献

The impact of participation in adult literacy programmes on learners’ identities is examined through an interrogation of their past and current experiences and the assessment of the effect of particular pedagogies. The findings show how learners’ positive experiences in their programmes had caused them to re-evaluate their previous understandings and enabled the construction of new identities as people that are able to learn. These changes had come about through the challenging of negative discourses, the creation of new figured worlds and imagined futures, and the use of a learning curriculum where learners’ experiences were utilized as positive resources. 相似文献

Jack in two boxes: A postmodern perspective on the transformation of persons into portraits 总被引:1,自引:0,他引:1
The paper explores issues surrounding portrayal in educational research and interrogates the notion of a life as a textual product, via an analysis of two short biographical narratives which happen to portray the same person — a British primary school head teacher nearing the end of his career. The discrepancies between these two texts point to the problematic nature of the relationship between person and portrait, and make visible some of the textual devices that writers/researchers use in order to achieve coherence and authenticity in biographical narratives. 相似文献

目前高校思想政治理论课的教育教学通过大学生的普遍正向认同来看已经取得了明显的成效。正向认同一般划分为强制性认同、利益性认同和观念性认同三个等级,它们对思想政治理论课的教育教学产生着正负两方面的影响。通过对三个认同等级及其在思想政治教育中的转变的分析,对思想政治理论课的改革和发展进行了一定的思考和探索。 相似文献

"脑死亡"的价值与挑战 总被引:6,自引:0,他引:6

脑死亡是由当代科学和医学技术进步给我们带来的一个全新问题,也涉及到复杂的经济、社会、伦理和法律等问题。脑死亡的提出意味着对于生和死的判别由经验转向了科学;凸显了大脑和心脏在人的生命系统和自我认同中的不同地位。在相当长的时期内,对于大多数社会成员来说,脑死亡标准不一定意味着对于心死亡标准的截然取代。而是将与其并存。脑死亡的实施提出了抢救生命的价值、代价和极限问题,将对生命终结标准的选择权和宣判权提出挑战,也将对人们通常的“孝”和“敬”等观念提出挑战。脑死亡的一个重要价值是有利于器官移植,而让生命以此种方式得以延续值得提倡。因此应当以一种更加开放的和进步的心态来积极推进有关脑死亡的立法。 相似文献

Research consistently indicates that Latinos and African-Americans are less likely to own and use computers than either Caucasians or Asians. While conventional wisdom holds that high computer costs and lack of access are the primary reasons for this discrepancy, my ethnographic research with 100 low-income adults reveals three non-cost-related psychosocial obstacles that significantly undermine motivation for acquiring computer skills: “relevance,” “fear,” and “self-concept.” My research thus suggests that a more complex relationship exists between ethnicity, identity, and attitudes associated with computers than previously examined; this relationship may better explain why some people are choosing not to use computers at this time. My research also indicates that while community technology centers (CTCs) play an important role in helping adults overcome their resistances and achieve computer literacy, they are presently an underutilized resource—less than 5% of San Diegans use them to meet their computing needs. Hence, my research also questions why more residents do not avail themselves of these community resources. I conclude that efforts to increase computer literacy in underserved communities must go beyond physical access and connectivity and consider the role of cultural factors. 相似文献
