Throughout their lives, individuals accumulate and apply lessons learned from instruction and experience. It is unclear how they transfer these lessons to become accomplished in their fields. In this exploratory study, we develop grounded hypotheses about the relationship of transfer to accomplishment. Selected individuals told stories about what they learned that influenced their major accomplishments, their sources, and timing. Findings indicate that individuality is magnified on the road to accomplishment, although shared lessons were evident. Attitudes and values, adopted and applied, seemed to play a special role in the passage from transfer to accomplishment.  相似文献

Few studies have examined the relation between maternal caloric intake during pregnancy and growth in child academic achievement while controlling for important confounding influences. Using data from the National Longitudinal Survey of Youth, the current study examined the effects of reduced prenatal caloric intake on growth in scores on the Peabody Individual Achievement Test from ages 5 to 14. While models controlling for within‐family covariates showed that prenatal caloric intake was associated with lower reading and mathematical achievement at age 5, models controlling for between‐family covariates (such as maternal IQ) and unobserved familial confounders revealed only a statistically significant association between siblings differentially exposed to prenatal caloric intake and mathematical achievement at age 5.  相似文献

The implementation of science reform must be viewed as a systems-level problem and not just focus on resources for teachers and students. High-capacity instructional leadership is essential for supporting classroom science instruction. Recent reform efforts include a shift from learning about science facts to figuring out scientific phenomena in which students use science practices as they build and apply disciplinary core ideas. We report findings from a research study on professional development (PD) to support instructional leaders' learning about the science practices. After participating in the PD, the instructional leaders' familiarity with and leadership content knowledge of the science practices significantly improved. Initially, principals used their understandings from other disciplines and content neutral visions of classrooms to make sense of science instruction. For example, they initially used their understandings of models and argument from ELA and math to make sense of science classroom instruction. Furthermore, some principals focused on content neutral strategies, like a clear objective. Over the course of the PD workshops, principals took up the language of the science practices in more nuanced and sophisticated ways. Principals' use of the language of the science practices became more frequent and shifted from identifying or defining them to considering quality and implementation in science classrooms. As we design tools to support science, we need to consider instructional leaders as important stakeholders and develop resources to specifically meet their needs. If the science feels too unfamiliar or intimidating, principals may avoid or reframe science reform efforts. Consequently, it is important to leverage instructional leaders' resources from other disciplines and content neutral strategies as bridges for building understanding in science. We argue that the science practices are one potential lever to engage in this work and shift instructional leaders' understandings of science instruction.  相似文献

Instructional videos are widely used to study teachers’ professional vision. A new technological development in video research is mobile eye-tracking (MET). It has the potential to provide fine-grained insights into teachers’ professional vision in action, but has yet been scarcely employed. We addressed this research gap by using MET video feedback to examine how expert and novice teachers differed in their noticing and weighing of alternative teaching strategies. Expert and novice teachers’ lessons were recorded with MET devices. Then, they commented on what they observe while watching their own teaching videos. Using a mixed methods approach, we found that expert and novice teachers did not differ in the number of classroom events they noticed and alternative teaching strategies they mentioned. However, novice teachers were more critical of their own teaching than expert teachers, particularly when they considered alternative teaching strategies. Practical implications for the field of teacher education are discussed.

Processes of designing for systemic innovation for sustainable development (SD) through the lens of three long-term case studies are reported. All case studies, which originated from the SLIM (Social Learning for the Integrated Management and Sustainable Use of Water at Catchment Scale) Project, funded within the EU Fifth Framework Program (2001–2004), constitute inquiry pathways that are explored using a critical incident approach. The initial starting conditions for each inquiry pathway are compared; significant pathway dependencies are identified which foster the development of social learning processes locally, but constrain their uptake and embedding across the wider system of interest. In the first case study, in England & Wales, promising developments in the application of social learning approaches to river basin planning over an initial 3-year period were subsequently marginalised, only to resurface towards the end of the 10-year period of study. In the second, South African case study, significant spaces for social learning and innovation in integrated water resources management were opened up over a five year period but closed down again, primarily as the result of lack of policy support by national government. The third, Italian, case study was designed to assess options for adapting to climate change by opening up new learning spaces between researchers, stakeholders and policy makers. A case for investing in local level systemic innovation through social-learning praxis design approaches and in learning processes around well contextualised case-studies is supported. However, concomitant investment by policy makers in social learning as an alternative, but complementary, governance mechanism for systemic innovation for SD is needed.  相似文献

Knowledge spillover occurs when recipient firms combine the knowledge of an originating firm with other knowledge. When recipient firms combine the originating firm's knowledge with knowledge that is unfamiliar to the originating firm, the recipient firms potentially provide insight to the originating firm on the viability of exploring such knowledge. By mimicking its recipient firms, the originating firm reduces the challenge and uncertainty of exploring unfamiliar knowledge domains. We examine the exploration activities of 87 telecommunications equipment manufacturers over a ten-year time period. We argue that those firms that operate in competitive and dynamic market environments promoting conservative risk-taking behavior will value such uncertainty reduction more highly and thus rely to a greater extent on their recipient firms for guidance on where to explore for new expertise. In contrast, firms in high-growth market environments are more likely to look beyond the activities of recipient firms when exploring new technological domains and rely less on mimicking their recipient firms.  相似文献

Fungi are non-chlorophyllus microorganisms, which constitutes the main source of outdoor and indoor allergens. The antigens present in the spores and fragments of hyphae induce allergic responses in sensitized patients. The frequently recognized fungi associated with asthma include Alternaria, Cladosporium, Aspergillus, and Penicillium. With the advent of molecular biology techniques a number of fungal genes encoding relevant allergens have been cloned and the expressed allergens purified and characterized. In this review, we have presented the recent developments, where recombinant allergens have been used in the precise diagnosis of fungal allergy. We have also discussed the role played by these allergens and the T- and B-cell epitopes in the immune mechanism in fungal allergy.  相似文献

This paper attempts to apply historical methods to help understand the relationship between the philosophy espoused in the works of Laozi or Tao De Ching and educational leadership. The objective is to study the thought of Laozi regarding leadership, to identify ideas and solutions that can be applied in modern educational management, as well as to provide a new definition and values to the ideas of Laozi. Laozi lived in ancient times, meaning that the works describing his thought are difficult to understand. The present study is primarily based on English sources written on Laozi by Ju-Chou Yang and on the commentary on Laozi by Bi Wang. Additionally, this article also refers to and compares other comments on the ideas of Laozi regarding management. This study finds that Laozi had varied ideas on management and philosophy. Laozi ’s views regarding organization are still relevant today. He stressed flexibility and the importance of adapting to the environment. As regards leadership, Laozi emphasized non-action, softness, humility, calmness and the elimination of desire. Furthermore, in his art of employment, Laozi insisted that leaders must overcome their personal likes and dislikes in relation to individuals to ensure the full utilization of their potential.  相似文献

Lesbian, gay, bisexual, transgender, and questioning or queer (LGBTQ) students at evangelical Christian colleges are a population frequently overlooked in the literature on the spiritual lives of college students. The author used qualitative content analysis within a phenomenological tradition to examine blog posts by such students, who face multiple identity challenges and official sanctions on campuses. Findings indicate these students want to be recognized as both LGBTQ and evangelical Christian by their colleges. Included are implications for counseling professionals and college administrators.  相似文献

Access arrangements are the way in which awarding bodies for public examinations in England, such as the General Certificate of Secondary Education, make reasonable adjustments for students with special educational needs and disabilities. SENCos have expressed concerns about the onerous nature of managing requirements for access arrangements, both administratively and practically, but there has been little explanation of why an apparently straightforward process proves so challenging. In this study, the development of a whole-school system to improve the administrative and practical management of access arrangements is used to seek to understand how the requirements set (and re-set) annually interact with school systems and processes to render the administration of access arrangements potentially complex, time-consuming and unpredictable. Scotland's flexible, school-led framework of requirements for the management of public examination assessment arrangements is highlighted as potentially more fit-for-purpose for the organisation of statutory reasonable adjustments for educational assessment.  相似文献
