The older one gets, the more one's life expectancy exceeds the population's given expectancy (at birth). Yet longevity is finite. This apparent paradox is analysed probabilistically with reference to empirical demographic data. 相似文献

Adapted primary literature (APL) is a novel text genre that retains the authentic characteristics of primary literature. Learning
through APL represents an educational intervention with an authentic scientific context. In this case study, we analyzed the
80-min discourse developed during the enactment of an article from an APL-based curriculum in biotechnology in one class,
and examined epistemic practices used by students during their meaning-making of the Results and Discussion sections of the
article. Specifically, we examined coordination practices, by which students connected elements belonging to different epistemic
status or context (theory, data, experimental stages, biotechnological applications and text). The application of coordination
practices was identified more than 70 times during the lesson. In the context of the Results section, the students displayed
research-oriented coordination practices, which were frequently associated with claims of comprehension difficulty. In the
context of the Discussion section, students displayed text-oriented coordination practices, associated with analysis of the
text characteristics. We are suggesting that the research-oriented coordination practices and some of the text-oriented ones
enabled the emergence of authentic scientific practices and learning by inquiry. Another type of text-oriented coordination
practice enabled reflection on scientists’ experimental processes, enabling learning science as inquiry. The enactment model
of APL used here allowed for both the emergence of the two dimensions of inquiry learning and the promotion of scientific
literacy in the fundamental and derived senses. 相似文献

Supporting Teaching and Learning Using Authentic Scientific Texts: A Rejoinder to Danielle J. Ford 总被引:1,自引:1,他引:0

In her commentary Danielle J. Ford mainly focused on three issues that highlight the promises and challenges for the use of
Adapted Primary Literature (APL) in science curricula: the possible contribution of APL to authentic experiences in secondary
schools, implementation issues of APL including the support required for the teachers, and the possibilities to extend the
use of APL to younger and older students. In this rejoinder, we first offer some general comments on Ford’s commentary. Then
we offer more specific comments on two areas of her response, authenticity and the support for teachers. 相似文献

Life sciences became Biology, a formal scientific discipline, at the turn of the nineteenth century, when it adopted the methods of reductive physics and chemistry. Mendel’s hypothesis of inheritance of discrete factors further introduced a quantitative reductionist dimension into biology. In 1910 Johannsen differentiated between the phenotype, which defines traits, and their genotype, the hereditary essence of such traits and their entities—the genes. The efforts to characterize these entities culminated in 1953, in Watson–Crick’s physico-chemical double helix model of DNA, the hereditary matter. However, the more molecular biology advanced the less real were its entities: Genes became generic units of heredity. The increasing role of science in society, and the mutual interdependence of the two on each other augmented the urge of the public at large to find in science icons of authority; the generic nature of the gene concept allowed scientists to offer it as the bait, even though advances in research made it clear that a distinction must be maintained between advances in reductive methodologies and the progress of systems’ conceptions. Genes out of context are meaningless. There are no “genes for” a trait: even if a specific change in a site on the DNA sequence may end in a conspicuous change in a trait, it must be realized that many sites in the DNA, in the cell, and in the organism as a complex integrated system in its environment, determine or rather, condition traits. The role of science is asking questions by putting up hypotheses and suggesting methods of testing them rather than in providing definite answers. 相似文献

This paper makes the case for adult literacy (including numeracy) practitioners to play a greater role in health literacy initiatives in Australia. The paper draws on data from a national research project that investigated adult literacy partnerships and pedagogy viewed from a social capital perspective. The primary purpose of the project was to produce guidelines on how to deliver integrated adult literacy and numeracy programmes using a social capital approach. Prior experience of partnerships was explored through a review of the literature and an environmental scan of adult literacy providers using an email survey and follow-up interviews. An in-depth case study of a health literacy partnership was trialled using action research. Partnerships between adult literacy and health organisations in Australia were found to be largely ad hoc and rarely documented. To enable sustainable health literacy programmes, partnerships are needed across the three interlinked organisational levels – micro, meso and macro, and in particular the latter, which is currently almost completely absent. The conceptual frameworks outlined for health literacy partnerships and social capital pedagogy in this paper are new and potentially of value to policy makers, researchers and practitioners in the fields of health and literacy. 相似文献

Every so often, it is important to stand back and look at the whole context of our field of research and practice. In this article, I do this by shedding light on the ways we view the term vocations and the consequences of those views for education and training in community colleges and adult and community education providers of all kinds. I ask the question: What is Vocational Education and Training (VET) for? I ask this particular question because I know the answers are contested, staking out claims for territory in research and practice. The answer to the question that this article explores is that vocational education and training ''serve industry.'' Using Australia as a specific example of such a Western country, the article argues that the entrenched meanings for VET as serving industry have disenfranchised a large proportion of the population - especially small business and the rural sector. The article is pointing out that the resulting version of VET is gendered, classed, and urban-specific. This structurally entrenched position is then contrasted with data reported from empirical studies currently examining (among other things) the nature of vocations and work at a community level and the manner in which they are created there. The article raises three important implications: the convergence of Adult and Community Education with VET, learning pathways, and the effects on small business. 相似文献
