Knowledge,education and research: Making common cause across communities of practice          下载免费PDF全文

Gemma Moss 《British Educational Research Journal》2016,42(6):927-944

This article considers how knowledge, education and research interact as the institutional structures that support them change. Many efforts at large‐scale education reform depend upon the proposition that what counts as useful knowledge can be easily defined, without reference to the specific contexts in which that knowledge will be set to work. Yet ?useful knowledge’ as it appears to policymakers does not always translate into ?useful knowledge’ from the perspective of practitioners. Distance and context matter. Based on studies of the development of literacy policy in England under successive governments, the paper assesses the dislocations and divisions of labour that characterise the contemporary knowledge landscape and asks how the research community can continue to act for the common good in an increasingly crowded and contested education field.  相似文献   

西安地区全新世环境变迁与土壤的形成演化     

周群英 《陕西教育学院学报》2004,20(3):107-111

根据对西安地区全新世黄土-古土壤覆盖序列和磁化率气候代用指标分析，揭示了全新世以来西安地区环境资源的变迁与土壤形成演化的过程。认为在全新世早期，气候比较温和干燥，风尘堆积速率降低，并有一定的生物风化成壤作用，土壤发育表现为边沉积边成壤；到了全新世中期，气候温暖湿润，沙尘暴很少发生，风尘堆积速率极低，植被覆盖度高，生物风化成壤作用达到最强，加上人类的耕作，形成了肥沃的褐土；到了3100多年前的全新世晚期，气候转为干冷，风尘堆积速率加强，环境资源恶化，土壤退化严重。  相似文献   

Components of Conceptual Ecologies   总被引：1，自引：0，他引：1  

Hyun Ju Park 《Research in Science Education》2007,37(2):217-237

The theory of conceptual change is criticized because it focuses only on supposed underlying logical structures and rational process processes, and lacks attention to affective aspects as well as motivational constructs in students’ learning science. This is a vast underestimation of the complexity and diversity of one’s change of conceptions. The notion of conceptual ecology provides a context for understanding individuals’ conceptual change learning, as it is the environment through which all information is interpreted. This research investigated how high school students’ statements, made in answering questions, reflect selected components of their conceptual ecologies. Data for this study was collected from six interviews in which seven students took part. The data also include the science teacher’s profiles of each student, the students’ personal journals, their assignments, and their examinations and answers in class. The analysis presented will here include only those components that were represented in the discourse of the seven high school students who were interviewed. When students were asked questions, there was evidence of the engagement of the various components of conceptual ecologies. These components include: epistemological commitments, metaphysical beliefs, the affective domain and emotional aspects, the nature of knowledge, the nature of learning, the nature of conceptions, and past experience. Evidence from this study suggests that these components might function as constraints to learning. This study contributes to the field by expanding our knowledge of the components of high school students’ conceptual ecologies through its definition of the categories and themes associated with those components. In examining across the range of components, the study illustrates the variety and sources of science conceptions within high school students’ conceptual ecologies.  相似文献   

概念隐喻研究综述     

陈文萃  曾燕波 《衡阳师范学院学报》2003,24(4):118-121

1980年莱考夫和约翰逊两人合著的《我们赖以生存的隐喻》一书，提出了一种迥然有别的隐喻知现——概念隐喻。从概念隐喻的理论、其所属范畴、哲学基础以及运用等方面对其内涵加以探讨，可以使人们进一步确信：隐喻作为一种认知现象，对人类思维方式、语言使用等方面的影响是极其广泛而深刻的。  相似文献   

Understanding higher education-based teacher educators’ identities in Hong Kong: a sociocultural linguistic perspective     

Rui Yuan 《Asia-Pacific Journal of Teacher Education》2016,44(4):379-400

While teacher educator identities have received increasing attention over the past decade, there is a lack of research on teacher educators’ professional identities in the complex and shifting higher education contexts. Informed by the sociocultural linguistic perspective, this study investigates two language teacher educators’ professional identities in Hong Kong universities. The findings show that the participants discursively constructed their identities, such as “accidental teacher educator,” “teacher educator-researcher,” “struggling researcher,” “teacher of teachers,” and “inactive researcher” in their professional work. By drawing on the three interrelated processes of identity formation (i.e. adequation/distinction, authentication/denaturalisation, and authorisation/illegitimation), the study adds to our knowledge of the complex and contested nature of teacher educator identity in relation to the ongoing restructuring and reform in higher education. The study concludes with some implications for teacher education and higher education.  相似文献   

隐喻思维方式初探：从莱可夫网上公开信谈起   总被引：2，自引：0，他引：2  

陈道明 《华侨大学学报(哲学社会科学版)》2001,(3):113-118

现代隐喻理论认为，隐喻不仅跟语言有关，而且也跟思维和判断推理有关。恰当的隐喻有助于人们作出正确的决策，而决策失误也往往与不恰当的隐喻有关，Lakoff发表在网上的公开信、Schǒn关于“贫民窟是疾病”或“贫民窟是自然社区”和“漆刷是水泵”的概念隐喻，清楚地说明了隐喻是如何被用来支配影响人们的判断推理和人民基于此判断推理之上的行为，以及隐喻如何被用来产生新视角，分析解释问题，为创造发明开辟新思路，本对此问题进行一些分析和探讨。  相似文献   

The Role of Self-Efficacy,Academic Abilities,and Parental Education in the Change in Career Decisions of Adolescents Facing German Unification     

Martin Pinquart  Linda P. Juang  Rainer K. Silbereisen 《Journal of Career Development》2004,31(2):125-142

In times of dramatic social change, new career options emerge and old options may become obsolete. We investigated predictors of change in general career aspirations and of plans to attend a university of East German adolescents from 1989 (before German unification) to 1991 and 1995, respectively, after German unification. Higher pre-unification self-efficacy beliefs were associated with an increase in general career aspirations and a higher probability of switching from non-college-bound vocational training to attending a university. In addition, better pre-unification school grades and having parents who graduated from a university increased adolescents' probability to switch to a university. Furthermore, interaction effects of self-efficacy with grades and cognitive abilities appeared, indicating that for individuals with high self-efficacy, cognitive abilities became more important and grades less important in predicting the wish to pursue university studies. We concluded that beliefs in one's capabilities, and high academic abilities are important resources in vocational reorientation in times of social change.  相似文献
