In this Forum, we construct a history of the National Association for Research in Science Education (NARST) through the analysis of documents and through the personal perspectives of individuals. The history of NARST is inseparable
from the biography of the individuals through whose lives it was produced and reproduced. The history of NARST is a living
history that both shapes and was shaped by the biographies of its members.

Conclusion Our experience with interactive distance education for science teachers has been both exciting and rewarding. This class has
convinced us that activity-based science method classes can be presented with this technology. Working with distance education
equipment requires the creative combination of long-established teaching techniques with novel procedures required by the
technology. Although the technology does involve inevitable limitations and compromises, it sharpens some teaching skills
and provides an opportunity for teachers to learn and do more science. As available tools for distance education become even
more sophisticated, delivery techniques will have to be altered continually. Doubtlessly, technological developments will
continue to be increasingly site friendly. In the future, one can anticipate forms of distance education that will enable
communication with an infinite number of remote sites, thus establishing the definitive electronic science classroom. 相似文献

Efforts to evaluate and improve student engagement have been pervasive in higher education over recent years. Critics argue, however, that troubling affinities are evident between student engagement efforts and a neoliberal agenda which emphasises accountability through performativity. Neoliberalism manifests in policies that focus on the economic benefit to individuals of higher education, rather than the broader social or intrinsic benefits. In this conceptual article, we draw on the work of Martin Heidegger and Nel Noddings in arguing that efforts aimed at promoting engagement and commitment to learn by students should include developing a capacity to care about others and things. Through the lens of care, our aim is to extend current notions of what engagement of students in their learning might look like. Challenging and supporting students entail encouraging them to take a stand on what they are learning and who they are becoming. This enriched conceptualisation has the potential to re-orient student engagement away from a narrow neoliberal agenda, while enabling students to realise the full benefits a higher education can provide. 相似文献

De Gruijter (1997) has claimed that May and Nicewander (1994) erred on two points that indicated that both reliability and information in the number-correct score could be reduced considerably by converting to percentile ranks. The points raised by De Gruijter are very well taken, and we are pleased to have an opportunity to respond. 相似文献

This article offers a philosophical-empirical account of embodied skilful performance in the practice of plant biotechnology. Drawing on the work of Merleau-Ponty and others, we elaborate how skilful performance emerges from and through reciprocal relations encompassing the body-in-the-world and the world-in-the-body. The contribution of this article lies in offering an account of skilful performance that is attentive to a perceiving, motile, feeling body entwined with world. In genetically modifying plants, scientists direct their senses of touch and vision to manipulating plant materials and matter, ‘reading’ subtle changes in tissue cultures, plantlets and so on. In rhythmic movements, they extend their bodies through skilful use of complex equipment, while calling on ‘intuition’ to guide their work. Skilful performance, then, relies on our lived body that is not merely a physical object among other objects, nor a passive instrument for the mind, but dynamic and inescapably entwined with people and things in a world in flux. Bringing to the fore how perceiving, motile, feeling bodies are implicated in skilful performance has significant implications for education and workplace training. 相似文献

During the last two decades there has been tremendous progress in the technique of trapping and cooling ions using quadrupole
ion traps. Using these trapping techniques one can have charged particles of a single species confined near the trap centre,
which enables to carry out studies of these ions in a well-controlled environment. The long storage times of the ions, possible
in these traps, results in the elimination of transit-time broadening making it possible to do precision spectroscopic measurements
on these ions. Several important experiments with single electron or ion have been undertaken to address problems related
to basic physics, such as the measurement of the electron radius, precision measurements of fundamental parameters and tests
of the predictions of quantum mechanics. 相似文献
