In 1971, on the death of Louis Pasteur's grandson, Pasteur Vallery-Radot, the collection of Pasteur's personal papers and notebooks, which had mostly been donated to the Bibliothèque nationale in Paris, became more accessible to scholars. Louis Pasteur (Fig. 1) was one of the world's greatest scientists, but since his death in 1895 his memory has been revered to an extent that almost borders on idolism. One consequence of the improved access to Pasteur's notebooks and correspondence was the publication in 1995 of Gerald Geison's book The Private Science of Louis Pasteur[1], in which Geison compares what he believes to have been the more realistic sequence of steps by which Pasteur reached his unquestionably famous discoveries with the widely publicized Pasteurian legends that often read more like film scenarios. This article attempts to trace the stages by which Pasteur came to some of his celebrated conclusions in the earlier years of his career.

Indigenous voices are largely silent in the outdoor education and adventure therapy literature. The purpose of this research collaboration was to understand how a 10-day outdoor adventure leadership experience (OALE) may promote resilience and well-being for Indigenous youth through their participation in the program. The process was examined through a community-based participatory research project that sought insight from the perspectives of one First Nations community in Canada. The OALE was implemented with six different groups for a total of 43 youth participants (ages 11.9–18.7 years) from Wikwemikong Unceded Indian Reserve in northeastern Ontario. Field data were collected from multiple sources including participant interviews, journals, focus groups, and talking circles. Using a critical ethnographic lens, we analyzed the data inductively to understand how the OALE promoted resilience and well-being. We listened to Indigenous voices, adhered to principles of Indigenous coding for thematic content and respected Indigenous ways of knowing for interpreting results. The process of connecting to the Good Life (Anishinaabe Bimaadziwin) or waking up (nsidwaaswok) to the Good Life emerged as the dominant theme. Connecting to the Good Life may offer a simple yet compelling way to understand the net impact of the OALE. 相似文献

This paper proposes how the theoretical framework of ecological dynamics can provide an influential model of the learner and the learning process to pre-empt effective behaviour changes. Here we argue that ecological dynamics supports a well-established model of the learner ideally suited to the environmental education context because of its emphasis on the learner–environment relationship. The model stems from perspectives on behaviour change in ecological psychology and dynamical systems theory. The salient points of the model are highlighted for educators interested in manipulating environmental constraints in the learning process, with the aim of designing effective learning programmes in environmental education. We conclude by providing generic principles of application which might define the learning process in environmental education programmes. 相似文献

This article explores 11- to 16-year-old students' explanations for phenomena commonly studied in school chemistry from an inclusive cognitive resources or knowledge-in-pieces perspective that considers that student utterances may reflect the activation of knowledge elements at a range of levels of explicitness. We report 5 themes in student explanations that we consider to derive from implicit knowledge elements activated in cognition. Student thinking in chemistry has commonly been examined from a misconceptions or alternative conceptions/frameworks perspective, in which the focus has been on the status of learners' explicit conceptions. This approach has been valuable, but it fails to explain the origins or nature of the full range of alternative ideas reported. In physics education, the cognitive resources perspective has led to work to characterize implicit knowledge elements—described as phenomenological primitives (p-prims)—that provide learners with an intuitive sense of mechanism. School chemistry offers a complementary knowledge domain because of its focus on the nature of materials and its domination by theoretical models that explain observable phenomena in terms of emergent properties of complex ensembles of “quanticles” (molecules, ions, electrons, atoms, etc.) The themes reported in this study suggest a need to recognize primitive knowledge elements beyond those reported from physics education and suggest that some previously characterized p-prims may be better considered to derive from more broadly applicable intuitive knowledge elements. 相似文献
