This paper describes a method of analysing teacher growth in the context of science education. It focuses on the identification of pathways in the development of secondary school teachers’ pedagogical content knowledge (PCK) by the use of the interconnected model of teachers’ professional growth (IMTPG).The teachers (n = 12) participated in a one-year action research project focused on their individual concerns related to teaching science. The use of the IMTPG revealed that teachers use different pathways of learning to develop different aspects of their PCK. For each PCK component, three distinct pathways could be identified, two of which clearly were associated with professional growth. When examining these two pathways in detail, it was found that (1) teachers learned about new instructional strategies and assessment methods mostly through literature reviews and discussions with peers and (2) teachers who analyzed and reflected on student learning as it happened in their classrooms developed understandings that helped them to select and apply instructional strategies to further promote student learning. Both the analytical method as well as the identification of the different developmental pathways help to better understand teacher development in the context of classroom practices. 相似文献

Practice‐led research in art and design has now come of age and can take its place alongside other forms of research at the academic ‘high table’. It no longer needs to be treated with ‘special consideration’ as a new form of intellectual enquiry. The research craft developed by those involved in practice‐led research admits them to a broader community of practice engaged in questioning the conceptual basis of how we perceive and make sense of the world around us. The objective/subjective divide that preoccupied an earlier generation of academics has eventually been replaced by a more nuanced epistemological framework able to embrace PhDs that include non‐textual artefacts as part of their exposition. An increasing number of academic institutions around the world have taken up the debate and now participate in practice‐led research programmes. However, for early‐career researchers in these fields there are still many hurdles to overcome, some of which are unique to this form of endeavour, as we outline. This article has been developed from a series of seminars and workshops presented by the authors to early‐career practice‐led researchers as part of their Project Dialogue programme which seeks greater engagement between the arts and sciences. 相似文献

University Counseling Centers (UCCs) experience high clinical demands and severe client presentations leaving counselors with limited time and resources to evaluate delivery of services. In this article, we present clinician-friendly quality improvement (QI) strategies used at a large Midwestern university and provide recommendations for implementing QI programs at other UCCs even as their resources may vary. With counselor-led efforts examining and evaluating services, UCCs can use QI programs to inform and improve counseling practices as well as advise university administrators about the positive outcomes of the center’s work. 相似文献

This article examines college student disengagement from sports, presents a multidimensional concept of athletic identity, and introduces a new measure intended to assist college counselors in their work with disengaged athletes. The Multidimensional Athletic Identity and Engagement Scale (MAIES) is introduced (Cronbach alpha .98, with subscale alphas between .78 and .96), and the results of exploratory and confirmatory factor analyses and convergent and divergent validity with 250 college student participants are presented. Using case examples, the authors discuss how counselors may use the MAIES in their work with students. Limitations of the study and suggestions for future research are discussed. 相似文献

More organizational leaders are recognizing that their greatest competitive advantage is the knowledge base of their employees and for organizations to thrive knowledge management (KM) systems need to be in place that encourage the natural interplay and flow of tacit and explicit knowledge. Approaching KM through the lens of the knowledge life cycle allows for the design and development of KM solutions that are systemic and address the dynamic nature of organizational knowledge. In this paper we provide a review of the literature regarding how organizational knowledge may be studied and propose a methodological framework for investigating the knowledge life cycle. To illustrate the framework we present a recent case study in which it was successfully used. This framework is intended to be useful to learning and performance improvement professionals who work in organizational KM as well as to researchers who wish to conduct further research in this area. 相似文献

Using two case studies of children’s knowledge, this paper sheds light on the value, diversity, and necessity of Indigenous and place-based knowledge to science and engineering curricula in rural areas. Rural contexts are rich environments for cultivating contextual knowledge, hence framing a critical pedagogy of teaching and learning. Indigenous and rural place-based knowledge are nuanced and pragmatic in character, and offer solutions to both local and global challenges. Two case studies, drawn from the experience of Lakota and Dakota communities and rural New York State, demonstrate the need to conserve, transmit, and contribute to Indigenous and rural knowledge through experiential and place-based education that bridges the gap between children’s knowledge and global STEM. This knowledge is inherently diverse in its complexity and connectivity to habitat, and when viewed in this light, has the capacity to transform our perspectives on educational practices and policies as well as our overall outlook on conserving both ecological as well as cultural diversity worldwide. Because diversity and knowledge are necessary for the survival of life on this planet, an enriched concept of pedagogical pluralism, in terms of multiple ways of knowing, is a necessity. 相似文献

The oxidative modification of lipoprotein especially low density lipoprotein (LDL) plays a key role in the initiation and
progression of atherosclerosis. Serum apolipoproteinB (apoB) level is found to be an important marker for atherosclerosis.
The present paper focuses on the measurement of serum apoB levels and the effect of Vitamin E, Vitamin C and reduced glutathione
on the copper ion induced oxidation of LDL + VLDL (VLDL-Very Low Density Lipoprotein) lipoprotein fraction isolated from the
serum of chronic renal failure (CRF) and renal transplanted patients. The level of apoB is significantly higher in the serum
of transplanted patients when compared to CRF patients and normal subjects. The level of TBARS formed in oxidized LDL + VLDL
lipoprotein fraction of CRF and renal transplanted patients are significantly increased than normal even in the presence of
antioxidants but the level of TBARS produced, with antioxidants is comparatively lesser than that produced by oxidized lipoprotein
fraction without antioxidants. It may be concluded than that produced by oxidized lipoprotein fraction without antioxidants.
It may be concluded that oxidation of LDL can be prevented at an earlier stage by Vitamin E supplementation. The supplementation
with Glutathione serves as the best method of preventing the lipoprotein oxidation among the renal diseased patients. 相似文献
