Eating Right: Linking Food‐Related Decision‐Making Concepts From Neuroscience,Psychology, and Education     

Matthias Doucerain  Lesley K. Fellows 《Mind, Brain, and Education》2012,6(4):206-219

This literature review uses four dimensions to classify and compare how food‐related decision‐making is conceptualized and experimentally assessed in neuroscience and other disciplines: (1) food‐related decision‐making other than the decision of what to eat that is part of each eating episode, (2) decision complexes other than the eating episode itself, (3) the evolution of food‐related decision‐making over time, and (4) the nature of food related decisions. In neuroscience in particular, food‐related decision‐making research has been dominated by studies exploring the influence of a wide range of factors on the final outcome, the type and amount of foods eaten. In comparison, the steps that are leading up to this outcome have only rarely been discussed. Neuroscientists should broaden their historically narrow conceptualization of food‐related decision‐making. Then neuroscience research could help group the numerous hypothesized influences for each of the decision complexes into meaningful clusters that rely on the same or similar brain mechanisms and that thus function in similar ways. This strategy could help researchers improve existing broad models of human food‐related decision‐making from other disciplines. The integration of neuroscientific and behavioral science approaches can lead to a better model of food‐related decision‐making grounded in the brain and relevant to the design of more effective school and nonschool lifestyle interventions to prevent and treat obesity in children, adolescents, and adults.  相似文献   

“It’s the X and Y Thing”: Cross-sectional and Longitudinal Changes in Children’s Understanding of Genes   总被引：1，自引：0，他引：1  

Lesley A. Smith  Joanne M. Williams 《Research in Science Education》2007,37(4):407-422

Studies from different theoretical traditions investigating children’s inheritance and genetics concepts have adopted a cross-sectional method. This paper is the first to examine both cross-sectional and longitudinal changes in children’s basic genetic concepts. It forms part of a larger investigation into the development of intuitive inheritance and genetics concepts in childhood. Four age cohorts (4–5 years, 7–8 years, 10–11 years, 14–15 years) were interviewed individually at two measurement occasions (T1, N = 182; T2, N = 164) separated by a 1-year interval. Cross-sectional analyses revealed an increase in children’s knowledge of genetics by 10 years. Between 10 and 14 years, there were fewer changes in the content of children’s knowledge, especially at the level of scientific genetic understanding. There was little evidence of longitudinal changes over the 1-year period. Overall, children may hold an understanding of genetics that is tied to knowledge of inheritance within families. This may pose challenges for acquiring more abstract and formal concepts of genes.  相似文献   

The Renewal of Science Teachers’ Knowledge: a pilot professional development project     

Lesley H. Parker  John W. Wallace  Barry J. Fraser 《Asia-Pacific Journal of Teacher Education》1993,21(2):169-177

This paper describes a pilot project for the professional development of science teachers, a major aim of which was to update teachers’ science content knowledge. The paper focuses on the rationale and background of the project, the model of inservice education, the arrangements for credentialling and recognising participating teachers, and the findings of the external evaluation of the initial stages of the project. It concludes with a summary of the features of the project which appear to be facilitating the achievement of its aims.  相似文献   

Rethinking the ‘Western Tradition’: a response to Enslin and Horsthemke     

Lesley Le Grange  Glen Aikenhead 《Educational Philosophy and Theory》2017,49(1):31-37

This is a reply to an article authored by Enslin and Horsthemke (2014) published in Educational Philosophy and Theory (EPAT). Enslin and Horsthemke argue that those who they refer to as ‘friends of the subaltern’ pit themselves against a straw-person that is swiftly dismissed in pointing out blindness of the Western tradition. They point out that in doing so ‘friends of the subaltern’ pursue a ‘politics of resentment’. In their reply, Le Grange and Aikenhead argue that Enslin and Horsthemke mischaracterise their work by cherry picking from their selected works and by taking their words out of context. They suggest that Enslin and Horsthemke produce their own straw-person arguments that they accuse others of doing. Le Grange and Aikenhead argue that their research programmes seek cognitive justice which is not tantamount to engaging in a politics of resentment.  相似文献   

An analysis of the role of peers in supporting female students’ choices in science subjects     

Debra Panizzon  Lesley Levins 《Research in Science Education》1997,27(2):251-270

This exploratory study investigated the role and importance of peers in providing personal and academic support for Year 11 female students, enrolled in physics and biology. While these areas of support had been identified in earlier research by Holland and Eisenhart (1981), this study attempted to investigate further their importance within an Australian context. Questionnaires, completed by one hundred female students, were analysed using Principal Components Analysis and MANOVA. The statistical analysis found no significant differences between the six relevant factors and science subjects, however, significant differences emerged in relation to schools and particular factors. Subsequently, six interviews were conducted with selected students to elaborate upon the statistical differences that emerged from these results. The interviews corroborated the findings of the quantitative analysis and provided explanations for these differences. Overall, the results of this study suggest that while the supportive role provided by peers is similar regardless of the science subject undertaken by a female student this role varies between schools.  相似文献   

Integrating multiple perspectives on the human-nature relationship: A reply to Fletcher 2017     

Matthew Zylstra  Karen Esler  Andrew Knight  Lesley Le Grange 《The Journal of environmental education》2019,50(1):1-10

The concept of “connectedness with nature” is increasingly used in environmental and sustainability discourse. However, this construct has also been critiqued and proponents charged with harboring an ambivalence that paradoxically reinforces a sense of separation from “nature”. We respond to one critique by demonstrating that whilst problematizing aspects of “connectedness with nature” has merit, selective use of examples misconstrues efforts in this field, undermines common ground and conflates theoretical conceptualizations with practical implementation. In addressing problems of perception and praxis, we emphasize the primacy of direct experience in shaping ways of knowing and recommend integral ecology (based on Wilber’s integral theory) as an inclusive framework for attending to multiple perspectives on the human-nature relationship.  相似文献   

Sleep and adjustment in preschool children: sleep diary reports by mothers relate to behavior reports by teachers   总被引：1，自引：0，他引：1  

Bates JE  Viken RJ  Alexander DB  Beyers J  Stockton L 《Child development》2002,73(1):62-75

Prior literature suggests that there may be relations between children's sleep disorders or inadequate amounts of sleep and behavioral adjustment. Most relevant studies concern clinical populations, however, and relatively few concern community populations. Moreover, previous studies have not addressed empirically the possible role of family functioning as a factor in the relation between children's sleep and adjustment. The present study, conducted in a predominantly low-income, community sample (N = 202), measured 4- to 5-year-old children's sleep patterns through daily logs kept by mothers, and measured family stress and parenting practices through detailed, multifaceted interviews and incidental observations of parent-child interactions. Children's adjustment, both positive and negative, was measured through preschool teacher reports on multiple occasions. A structural equation model showed that disrupted child sleep patterns (variability in reported amount of sleep, variability in bedtime, and lateness of bedtime) predicted less optimal adjustment in preschool, even after considering the roles of family stress and family management practices.  相似文献   

Mission Impossible? Access and the Dash to Growth in British Higher Education   总被引：1，自引：0，他引：1  

David N. Smith  Peter Scott  Lesley Mackay 《Higher Education Quarterly》1993,47(4):316-333

Access is a central issue in the debate about the future shape and characteristics of the post-binary system of higher education. It is seen as crucial to the shift towards a more open, mass system. This paper examines commitments to access in the contents of institutional missions and strategic plans. The results of our analysis suggest a widespread concern to be involved in the access process. However, we also reveal substantial differences in emphasis between the older universities, ex-polytechnics and colleges that comprise the post-binary system. On the basis of present institutional planning it would appear that access is frequently seen as an addition to, rather than a replacement of, the commitments of the binary era. Our evidence suggests that a fundamental shift of ethos within the system as a whole may be some way off.  相似文献   

Interaction in distance education — a case study: Teaching biology at two rural schools     

Lesley Lehmann 《Distance Education》1992,13(1):131-145

There are many instances where distance education for children is in a state of upheaval and change. This is particularly true of Australia and, as earlier reports indicate, of Canada. Central planners often have abandoned the old ‘correspondence schools’ and established ‘open access’ centres; central schools have been de‐centralised; correspondence stuthes are offered to children in city schools; isolated children attend ‘classes’ vastly different from their old ‘School of the Air’ classes; etc. Some of these changes are the marks of progress; the quality of other changes is debatable.

This account is that of one country teacher operating in northern South Australia where distance education has now changed to be offered, Statewide, by a series of open access schools and has also been regionalised to be offered at the initiative of Education Department Regional Centres with a broad responsibility for education of children in their region. The article makes no pretence to being considered as ‘international research literature’ — some will question whether or not it is even distance education. It is being published at my request.

The teacher functions in an areaof small country towns 50 km apart and with 500 or so people. Not too much further north, into sparsely‐watered country, the towns are likely to have 50 or so people and are up to 500 km apart!

What the paper does highlight is that there are professional people ‘out there’ who see themselves as having a stake in distance education. Central administrators and those who regard themselves as scholars in distance education are only a part of the personnel in distance education.

Using a blended learning approach to support women returning to STEM     

Clem Herman  Rosaria Gracia  Lesley Macniven  Bernie Clark  Geraldine Doyle 《Open Learning》2019,34(1):40-60

ABSTRACT

This paper examines a blended learning model designed to support women returning to STEM after a career break and its delivery in a unique partnership between an online distance education provider and a community-based equality organisation. Through this partnership additional activities such as networking events, returnships, career clinics and webinars were used in conjunction with a structured online Badged Open Course (BOC), which enabled a successful return to employment for many of the participants. This article outlines the results and implications of this integrated model and argues that blended learning approaches need to be flexible and adaptable to be able to incorporate the needs of learners at different life-course stages, taking into consideration gender and other diversity characteristics.  相似文献
