This article discusses the issue of the sustainability of educational change in the light of findings from research undertaken in tandem with a development project initiated by a Scottish Education Authority, The Highland Council. The paper reviews some of the key themes that have emerged from recent literature on educational change, before drawing on the project data to address two key issues: the factors that have helped to promote and sustain changes within the schools; and the barriers to innovation experienced in these schools. We conclude the article by identifying a range of considerations that should be taken into account by those seeking to innovate and we suggest that, while the Highland model for change has enjoyed a degree of success in inculcating change, more needs to be done to address systemic issues, such as the pervasive influence of a narrow attainment agenda in shaping classroom practice. 相似文献

The purpose of this qualitative interpretive research study was to examine high school students’ written scientific explanations
during biology laboratory investigations. Specifically, we characterized the types of epistemologies and forms of reasoning
involved in students’ scientific explanations and students’ perceptions of scientific explanations. Sixteen students from
a rural high school in the Southeastern United States were the participants of this research study. The data consisted of
students’ laboratory reports and individual interviews. The results indicated that students’ explanations were primarily based
on first-hand knowledge gained in the science laboratories and mostly representing procedural recounts. Most students did
not give explanations based on a theory or a principle and did not use deductive reasoning in their explanations. The students
had difficulties explaining phenomena that involved intricate cause–effect relationships. Students perceived scientific explanation
as the final step of a scientific inquiry and as an account of what happened in the inquiry process, and held a constructivist–empiricist
view of scientific explanations. Our results imply the need for more explicit guidance to help students construct better scientific
explanations and explicit teaching of the explanatory genre with particular focus on theoretical and causal explanations. 相似文献

The purpose of this study is to develop and validate a new instrument to measure the multidimensional nature of motivations to engage in healthy behavior practices among older adults. The Healthy Aging Incentives Scale (HAIS) was developed empirically from data collected from 158 older adults participating in a health and wellness clinic located within a multipurpose senior center in the United States. A factor analysis of the HAIS revealed five themes prompting older adults to participate in health aging practices: health and fitness, psychological well-being, locus of control, social functions, and socialization attributes. Additional data are provided that support reliability and validity of the HAIS including convergent validity of the 20-item scale by its correlation with healthy behavior habits. Conclusions are drawn showing literature support for the multidimensional scale and the important determinants for promoting healthy outcomes for this population. 相似文献

Using a phone survey conducted in 2012, we examined whether there is a gender difference in financial literacy among Hong Kong workers; and if such a difference exists, whether it can be explained by gender differences in sociodemographic variables, social or psychological factors, and/or the outcomes of retirement planning. Results show a gender gap in financial literacy as well as age, spousal support for retirement savings, risk tolerance, computational ability, and perceived financial knowledge. Multivariate data analyses show that a proportion of the gender difference in financial literacy could be explained by gender differences in risk tolerance, computational ability, and self-reported financial knowledge; but the difference remained after adjusting for variables found to be associated with gender. Our findings suggest that it may be important to develop programs targeted specifically to women. 相似文献

This paper traces the academic identity formation(s) of 10 Canadian female academics whose disciplinary knowledge is in the field of educational administration. We trace the ways in which discourses of gender, institutional power, and other cultural and social influences shaped their sense of themselves as academics in the highly patriarchal domain of the academy as an institution as well as within the discourse(s) of educational administration in faculties of education. In doing so, we discuss the ways in which these women's entry into academia transformed identity possibilities for themselves and others. We conclude that these women share a commitment to rigorous scholarship and to the values of equity and social justice. The way in which they engage with those values in their work and lives has been taken up in the particular institutional and personal circumstances of their academic lives and has been shaped by the effects of normative discourses of gender. The result, individually and cumulatively, has been transformative on the individuals, within the institutions in which they have worked, and on the scholarship of Canadian educational administration. 相似文献

This paper explores the construction of dominant models of gender among students in the Vocational–Technical. In the backdrop of dominant narratives that structure gender policies and practices in schooling in Zimbabwe, the paper elaborates upon how students’ daily experiences in workrooms perpetuate the feminisation and masculinisation of fields of study such as DT and HESs in ways that inhibit the learning and achievement of boys and girls in these subjects. The argument in this paper is that in order to understand gender inequality in the Voc-Tech curriculum, educators need to understand how sociocultural perceptions of gender are constructed and embodied at the level of classroom interaction among students and teachers. Such insights provide a deeper understanding for addressing gender inequality in Voc-Tech subjects that moves beyond current structural and institutional barriers within a rural African context. 相似文献

We describe a scalable artificial bilayer lipid membrane platform for rapid electrophysiological screening of ion channels and transporters. A passive pumping method is used to flow microliter volumes of ligand solution across a suspended bilayer within a microfluidic chip. Bilayers are stable at flow rates up to ∼0.5 μl/min. Phospholipid bilayers are formed across a photolithographically defined aperture made in a dry film resist within the microfluidic chip. Bilayers are stable for many days and the low shunt capacitance of the thin film support gives low-noise high-quality single ion channel recording. Dose-dependent transient blocking of α-hemolysin with β-cyclodextrin (β-CD) and polyethylene glycol is demonstrated and dose-dependent blocking studies of the KcsA potassium channel with tetraethylammonium show the potential for determining IC50 values. The assays are fast (30 min for a complete IC50 curve) and simple and require very small amounts of compounds (100 μg in 15 μl). The technology can be scaled so that multiple bilayers can be addressed, providing a screening platform for ion channels, transporters, and nanopores. 相似文献

The combining of subject areas or disciplines, referred to in this article as curriculum integration, has been recognised as being linked to high levels of student motivation and learning. Sheryl MacMath of the University of Toronto, Jillian Roberts of the University of Victoria, and John Wallace and Xiaohong Chi of the University of Toronto discuss the findings of their case study (n = 23 students) based in a Canadian secondary school where an integrated unit on energy was taught to pupils identified as being ‘at risk’ of not completing high school. Teacher and student interviews, classroom observations and surveys were used in the case study to investigate student motivation and learning. Results from the study illustrate that students experienced higher levels of motivation and academic success compared to work on previous units. The authors explore how higher levels of student self‐efficacy were also recorded due to the repetition of content in different classrooms and across different contexts. The authors argue that further research in this area should examine more than student learning and motivation and highlights the need to focus specifically on opportunities for successful academic experiences where student efficacy is increased. 相似文献
