Being in the moment, showing compassion, being non-judgmental, acknowledging deep emotional challenges without getting stuck: these are mindfulness characteristics important to us as teachers, yet not often included in teacher preparation. These concerns become magnified when we focus on difficult knowledge and thorny issues, like topics related to gender and race. Using a sociocultural framework, we address how mindfulness, heuristics, and other contemplative practices can be adopted to create safe, supporting, and healing spaces for such complex, often emotionally painful discussions. Participant narratives are used extensively to provide a voice to those marginalized or hurt. Drawing from these narratives and their experience in discussing thorny issues, we put forth possible solutions and interventions that can create spaces that encourage and support critical discourse through mindful practices. The development of a heuristic for discussing thorny issues whose characteristics can be adopted by interested teachers and educators to help frame and mediate this type of difficult discussion is an outcome of this research. 相似文献

NATURAL SCIENCES IN KINDERGARTEN: A SOCIO-COGNITIVE FRAMEWORK FOR LEARNING AND TEACHING – The present study presents a socio-cognitive framework for the construction of the scientific knowledge of natural phenomena among pre-school children and for the development of science activities at kindergarten. It involves elements from theories of social interaction; social psychology of development and cognitive functioning; and research in natural-science teaching methods which acknowledge the importance and fundamental role of social interaction in the development of cognitive operations and learning. The study also presents some of the more significant results of the research carried out on different aspects of this topic. The discussion unfolded here supports the hypothesis that the construction of natural-scientific knowledge at the pre-school age and corresponding scholastic activities are necessary and effective.
Zusammenfassung NATURWISSENSCHAFTEN IM KINDERGARTEN: EIN SOZIO-KOGNITIVER RAHMEN FÜR LERNEN UND LEHREN – Die vorliegende Studie legt einen sozio-kognitiven Rahmen für die Herausbildung naturwissenschaftlichen Wissens von Vorschulkindern und für die Entwicklung wissenschaftlicher Aktivitäten im Kindergarten vor. Sie bezieht Elemente aus Theorien der gesellschaftlichen Interaktion ein, der Sozialpsychologie von Entwicklung und kognitiver Funktion sowie der Erforschung der Lehrmethoden in der Naturwissenschaft, welche die Bedeutung und grundlegende Rolle der gesellschaftlichen Interaktion in der Entwicklung kognitiver Operationen und des Lernens feststellen. Die Studie legt ferner Forschungsergebnisse vor, die bezüglich verschiedener Aspekte dieses An- satzes erzielt wurden. Die Diskussion, die hier entfaltet wird, unterstützt die Hypothese, dass die Bildung naturwissenschaftlichen Wissens im Vorschulalter und die entsprechenden schulischen Aktivitäten notwendig und wirkungsvoll sind.

El estudio también presenta algunos de los resultados más significantes de la investigación realizada sobre diferentes aspectos de esta temática. La discusión desplegada aquí apoya la hipótesis de que la construcción del conocimiento sobre ciencias naturales en la edad preescolar y las correspondientes actividades son necesarias y efectivas.
Résumé Cet article présente un cadre théorique sociocognitif consacré à l’étude de la construction des connaissances des phénomènes physiques chez les enfants d’âge préscolaire ainsi qu’au développement des activités scientifiques à l’école maternelle. Ce cadre se compose d’une articulation des éléments théoriques produits par les théories de l’interactionnisme social, de la psychologie sociale du développement et du fonctionnement cognitif, et par les résultats de la recherche en didactique des sciences physiques qui, en général, reconnaissent l’importance et le rôle fondamental de l’interaction sociale dans le développement d’opérations cognitives et d’apprentissages. Cet article présente également quelques-uns des résultats les plus significatifs des recherches effectuées sur différents aspects de l’approche choisie. La discussion de ces résultats peut conduire à rendre claire l’hypothèse selon laquelle tant la construction des connaissances des phénomènes physiques que la création d’activités scolaires sont nécessaires et efficaces à l’âge préscolaire.相似文献

While modern science is receiving harsh criticism within the framework of environmental education, at the same time ecology is presented as an alternative science, characterized as ‘holistic’ and ‘non‐exploitative’. However, many of the characteristics of the science of ecology do not comply with its characterization as alternative science. Furthermore, ecology is a science with competing paradigms, provisional theories, incommensurable worldviews, and extensive theoretical and methodological debates. The treatment of the science of ecology in environmental education is not taking into account the relevant evidence, resulting in a quite strong positivistic and dogmatic educational approach. The importance of approaches that comply more with a post‐positivistic account of education are discussed in the light of the possible contribution of environmental education to science education discourse. 相似文献

Creating and using knowledge: an analysis of the differentiated nature of workplace learning environments 总被引：1，自引：0，他引：1

This paper argues that contemporary workplaces give rise to many different forms of knowledge creation and use, and, as a consequence to different forms of learning and pedagogical approaches. Some of these are utilised to the benefit of the organisation and employees (though not, necessarily, in a reciprocal manner), but others are buried within everyday workplace activity. The discussion builds on earlier work where it was argued that organisations differ in the way they create and manage themselves as learning environments, with some conceptualised as ‘expansive’ in the sense that their employees experience diverse forms of participation and, hence, are more likely to foster learning at work. By studying the way in which work is organised (including the organisation of physical and virtual spaces), this research is suggesting that it is possible to expose some of this learning activity as well as to identify examples where new (or refined) knowledge has been created. In this regard, it is argued that it is important to break down conceptual hierarchies that presuppose that learning is restricted to certain types of employee and/or parts of an organisation and to re‐examine knowledge as applied to the workplace. The conclusion focuses on how such an approach, and in particular the use of a productive system analysis, is strengthening the concept of expansive and restrictive learning environments. 相似文献

In this paper we analyse the language used by kindergarten children and their teacher while they discuss the fairness of two
games that involved the concept of chance. Their discussions show that the children are able to overcome their primary intuitions
concerning the fairness of a game and to comprehend the important role of materials. The children mostly used counting strategies
in order to justify their opinion; this reveals the establishment of a primary discursive community based on the premise that
each opinion should be justified in order to be accepted by the other children and the teacher.

The 'global' quality of the caregiving environment for young infants and toddlers in day care centres in Athens, the 'structural' and 'dynamic' features in terms of group size, the adult child ratio, the caregiving style and, finally, the interaction patterns developed between the caregivers and the children, were all factors evaluated for potential developmental effects. Participants in the study were 60 toddlers, experiencing full-time (more than 20 hours/week) day care provision, and for at least 6 months out-of-home care, while attending 25 day care centres located in the greater Athens area. Children's assessments included measures of cognitive, language and socio-emotional development. Interviews and observational techniques were used to assess the quality of the day caregiving environment and the interaction processes between caregivers and the children. Children's development was considered in terms of the quality of out-of-home care experience. It was found that the course of development could be predicted by the overall day care centre quality index as measured by the ITERS scale, with the separate contribution of some other variables according to the examined developmental aspect. Dans le cadre d'une recherche concernant les influences possibles sur le développement des enfants, nous avons étudié les facteurs suivants: l'évaluation 'globale' de la qualité de l'environnement des services de soin et d'éducation dans les crèches d'Athènes, les caractéristiques 'structurelles' et 'dynamiques' concernant la taille du groupe d'enfants en classe, l'analogie institutrices/enfants, le style de soin et de comportement de l' institutrice, enfin, le style d'interaction entre institutrices et enfants. Dans cette recherche ont participé 60 enfants de 18 mois, fréquentant 25 crèches de la région d'Athènes pour plus de 20 heures par semaine et pour une durée d'au moins 6 mois au moment de la recherche. L'appréciation du développement des enfants concernait le domaine cognitif, langagier et socio-émotionel. Pour l'évaluation de la qualité de l'environnement des crèches et les processus d'interaction entre institutrices et enfants, nous nous sommes servi de méthodes d'interview et d'observation. Le développement des enfants a éte´ évalué en fonction de la qualité de l'environnement des crèches. Nous avons conclu que le développement est corrélé avec la qualité globale de la crèche, telle qu'elle a été calculé avec l'échelle ITERS. Par ailleurs, nous avons observé la contribution d'autres variables selon le secteur étudié du développement. La apreciación "global" de la calidad del ambiente de la prestación de servicios de cuidados y educación a los niños en las guarderías infantiles de Atenas, las características "estructurales" y "dinámicos" que conciernen al número de los niños en la clase, a la proporción maestras/niños, al estilo de la prestación del cuidado y del comportamiento de las maestras y, en fin, al esquema de interacción entre maestras y niños han sido los factores que se han examinado en cuanto a su possible influencia sobre el desarrollo de los niños. En nuestra investigación participaron 60 niños de 18 meses de edad que frecuentaban 25 guarderías en la región de Atenas durante más de 20 horas a la semana y por lo menos 6 meses hasta la investigación. La apreciación del desarrollo de los niños se refiere al sector cognitivo, verbal y socio-emocional. Para la evaluación de la calidad del ambiente de las guarderías y para los procedimientos de intercambio entre maestras y niños se han utilizado las técnicas de la entervista y de la observación. El desarrollo de los niños se ha apreciado en relación con la calidad del ambiente de las guarderías. Ha resultado evidente que el curso del desarrollo guarda relación con la calidad general de la guardería, la cual se ha evaluado según la escala ITERS, mientras se ha notado también el aporte de otras variables, según el aspecto del desarrollo estudiado. 相似文献

This work investigates the effect a Web 2.0 learning environment may have in higher education in adding value to the students’ existing competencies. The major issues that this work examines are whether the incorporation of a Web 2.0 environment in higher education has an effect on the students’ performance and what are the significant factors that should be taken into account in the deployment of these technologies to achieve the maximum possible benefits and whether and how they correlate to each other. These factors are derived from the students’ views on the use of technology in a university course deployment and from the students’ personal opinions about a pilot course in a Web 2.0 learning environment. Although the results indicate no direct effect on the students’ performance, significant factors have been revealed via a thorough assessment, which has been performed in the context of a semester–long course, utilizing statistical process control techniques. The derived factors are namely: “Technology as an educational reinforcement”, “Technology as a tool to enhance comprehension” and “Enhancement of student interest and experience”, while in the second one “Completeness of the educational approach”, “Satisfaction from the educational approach” and “Course demands”. These factors can then form the basis for a feedback processes and a monitoring mechanism for a continuously updated educational process. 相似文献

The ‘Balance of Nature’ metaphor is a pervasive idea in ecology. However, the scientific community acknowledged during the
last decades that equilibrium conditions are rare, while disturbance events are not uncommon. We suggest that the exclusive
teaching of the ‘Balance of Nature’ metaphor produces cultural, scientific and learning misconceptions about the structure
and function of nature. We outline an exemplary educational intervention for high school students to exhibit that the use
of computer simulations could serve important educational goals in ecology and environmental education, such as the liberation
of the concept of ‘balance’ of its metaphysic burden, the comprehension of the dynamics and the systemic nature of ecological
processes and the appreciation of the mutual relation between society and nature. 相似文献

Influence theories constitute formal models that identify those individuals that are able to affect and guide their peers through their activity. There is a large body of work on developing such theories, as they have important applications in viral marketing, recommendations, as well as information retrieval. Influence theories are typically evaluated through a manual process that cannot scale to data voluminous enough to draw safe, representative conclusions. To overcome this issue, we introduce in this paper a formalized framework for large-scale, automatic evaluation of topic-specific influence theories that are specialized in Twitter. Basically, it consists of five conjunctive conditions that are indicative of real influence exertion: the first three determine which influence theories are compatible with our framework, while the other two estimate their relative effectiveness. At the core of these two conditions lies a novel metric that assesses the aggregate sentiment of a group of users and allows for estimating how close the behavior of influencers is to that of the entire community. We put our framework into practice using a large-scale test-bed with real data from 75 Twitter communities. In order to select the theories that can be employed in our analysis, we introduce a generic, two-dimensional taxonomy that elucidates their functionality. With its help, we ended up with five established topic-specific theories that are applicable to our settings. The outcomes of our analysis reveal significant differences in their performance. To explain them, we introduce a novel methodology for delving into the internal dynamics of the groups of influencers they define. We use it to analyze the implications of the selected theories and, based on the resulting evidence, we propose a novel partition of influence theories in three major categories with divergent performance. 相似文献

In this study, we assessed the effects of a 4 week basic military physical training programme for male recruits of the Hellenic Air Force on the number and distribution of circulating immune cells and adrenergic and adrenocortical hormonal responses. One group of recruits (exercised, n = 48) participated in moderate intermittent physical exercise, whereas a second group (non-exercised controls, n = 9) performed only light work in the barracks. Both groups participated in the same non-physical, classroom-type training and testing. Military training by the exercised group resulted in significant increases in CD4+ T-lymphocytes, renal cortisol excretion and the urinary noradrenaline/adrenaline ratio, together with reductions in neutrophils and the neutrophil/lymphocyte ratio. In the exercised group, the urinary noradrenaline/adrenaline ratio correlated positively with the training-induced changes in CD4+ T-lymphocytes and negatively with changes in the neutrophil/lymphocyte ratio. No significant relationship was found between training-induced increases in cortisol excretion and any of the peripheral blood cell alterations. Our results indicate that 4 weeks of military training consisting of intermittent moderate exercise resulted in a significant increase in CD4+ T-lymphocytes and reduction in neutrophils. These changes were probably driven by alterations in hormonal status, including the significant impact of sympathetic nervous system activation. 相似文献
