Intercorporeality and ethical commitment: an activity perspective on classroom interaction   总被引：1，自引：0，他引：1  

Luis Radford  Wolff-Michael Roth 《Educational Studies in Mathematics》2011,77(2-3):227-245

In this article, we present a sociocultural alternative to contemporary constructivist conceptions of classroom interaction. Drawing on the work of Vygotsky and Leont??ev, we introduce an approach that offers a new perspective through which to understand the specifically human forms of knowing that emerge when people engage in joint activity. To this end, we present two concepts: space of joint action and togethering. The space of joint action allows us to capture the collective and sensuous or intercorporeal dimensions of thought and feeling in interaction. We resort to the concept of togethering to capture the ethical commitment participants make to engage in and produce activity. These concepts are illustrated through a discussion of concrete episodes from an elementary mathematics classroom.  相似文献   

A psychosocial approach to shame,embarrassment and melancholia amongst unemployed young men and their fathers     

Luis Jimenez  Valerie Walkerdine 《Gender and education》2011,23(2):185-199

This paper uses a psychosocial approach to explore young unemployed men’s resistance to work they describe as ‘embarrassing’ and ‘feminine’, in the context of the closure of a steelworks in a town in the South Wales valleys. In our psychosocial interview‐based study, with young men as well as their mothers and (where possible) their fathers, we found a community riven with complex feelings about masculinity and femininity, projected on to the young men in such a way as to almost scapegoat them. The experience of the young men was marked by embarrassment and shame. They feel bullied and shamed by their families, peers and others in the community for not being able to find gender‐appropriate work.  相似文献   

Identity Production in Figured Worlds: How some Mexican Americans become Chicana/o Activist Educators   总被引：1，自引：0，他引：1  

Luis UrrietaJr. 《The Urban Review》2007,39(2):117-144

Using Holland, Lachicotte, Skinner, and Cain’s (1998) theory of identity and their concept of figured worlds, this article provides an overview of how twenty-four Mexican Americans came to produce Chicana/o Activist Educator identities. The desire to raise consciousness (teach for social justice pero con ganas) and “give back to the [their] community” became a very important part of this identity. Using an ethnographic interview as well as a life history interview methodology, this article specifically focuses on the participants’ conceptual and procedural identity production in local Chicana/o activist figured worlds (usually in colleges and universities). In these local figured worlds, the participants produced a more complex process of identity production that was both conceptual and procedural. The article concludes with broad implications for urban teacher education. Luis Urrieta, Jr. is assistant professor of cultural studies and education and Fellow in the Lee Hage Jamail Regents Chair in Education at the University of Texas at Austin. His research interests are in identity, agency, and social movements in education with a focus on Chicana/o and Indígena (P’urhépecha) education, citizenship and social studies education. 1 University Station D5700, Austin, TX 78712, USA.  相似文献

Multidimensional relevance: Prioritized aggregation in a personalized Information Retrieval setting     

Célia da Costa Pereira  Mauro Dragoni  Gabriella Pasi 《Information processing & management》2012

A new model for aggregating multiple criteria evaluations for relevance assessment is proposed. An Information Retrieval context is considered, where relevance is modeled as a multidimensional property of documents. The usefulness and effectiveness of such a model are demonstrated by means of a case study on personalized Information Retrieval with multi-criteria relevance. The following criteria are considered to estimate document relevance: aboutness, coverage, appropriateness, and reliability.  相似文献   

Conceptions and knowledge about childhood in initial teacher training: Changes in recent decades and their impact on teacher professionality, and on schooling in childhood     

Ftima Pereira 《Teaching and Teacher Education》2009,25(8):1009-1017

This paper looks at changes in the conceptions of childhood in recent decades, and their contribution to the understanding of the sociabilities and subjectivities that are moulded in school, and how these relate to teachers' initial training. An overview of social changes in late modernity is given, and their impact on teacher professionality and the conception of childhood considered. The results are given of a study on conceptions of childhood, expressed in or related to the initial training of teachers in the 1st Basic Education Cycle (CEB), in Portugal since April 1974.  相似文献   

Using context variety and students' discussions in recognizing statistical situations     

Jos Luis ngel Rodríguez Silva  Mario Snchez Aguilar 《Teaching Statistics》2016,38(1):22-24

We present a proposal for helping students to cope with statistical word problems related to the classification of different cases of confidence intervals. The proposal promotes an environment where students can explicitly discuss the reasons underlying their classification of cases.  相似文献

Carnation Atoms? A History of Nuclear Energy in Portugal     

Tiago Santos Pereira  Paulo F. C. Fonseca  António Carvalho 《Minerva》2018,56(4):505-528

Drawing upon the concepts of civic epistemologies and sociotechnical imaginaries, this article delves into the history of nuclear energy in Portugal, analyzing the ways in which the nuclear endeavor was differently enacted by various sociopolitical collectives – the Fascist State, post-revolutionary governments and the public. Following the 1974 revolution - known as the Carnation Revolution - this paper analyzes how the nuclear project was fiercely contested by a vibrant anti-nuclear movement assembled against the construction of the Ferrel Nuclear Plant, the first sociotechnical controversy in Portugal, paving the way for the emergence of a combative civic epistemology. Supported by semi-structured interviews with scientists, activists and local residents of Ferrel and the analysis of historical material, this article presents the failed Portuguese nuclear endeavor as an emblematic case study to explore the co-production of science and society, in particular the role of revolutionary processes in the unfolding of sociotechnical controversies.  相似文献   

Cardiorespiratory fitness and arm bone mineral health in young males with spinal cord injury: the mediator role of lean mass     

Irene Rodríguez-Gómez  Soraya Martín-Manjarrés  María Martín-García  Sara Vila-Maldonado  Ángel Gil-Agudo  Luis M. Alegre 《Journal of sports sciences》2019,37(7):717-725

Spinal cord injury (SCI) derives in loss of bone mineral content (BMC) and bone mineral density (BMD). However, physical activity is an important determinant in bone mass acquisition, which is partially mediated through the lean mass (LM). The aim was to examine the effect of cardiorespiratory fitness (CRF) on BMD and BMC arms of adult males with SCI and able-bodied controls using the arm LM as a mediator variable. Thirty able-bodied men and thirty men with SCI participated. BMC and BMD were analysed by DXA, and indirect calorimetry was used to calculate VO_2peak during a progressive arm-cranking test. When groups were divided by the amount of LM, the subgroup with highest LM had significantly higher arm BMC compared to the lowest LM subgroup (p ≤ 0.05) in both SCI and able-bodied groups. Moreover, same differences were found when confidence intervals were analysed. Only in the SCI group, arm LM mediated the relationship between bone mass and CRF at 30.9%, as indicated by the Sobel test (z = 2.17 and z = 2.04 for BMC and BMD, respectively). In conclusion, LM mediates the indirect association between CRF and bone health, specifically in the arms. This finding highlights the importance of having an adequate CRF for the maintenance of good bone health in SCI men.  相似文献
