Recollection of early childhood experiences was investigated in 225 European Canadian and 133 Chinese children (ages 8, 11, and 14) by a memory fluency task that measured accessibility of multiple early memories and elicited the earliest memory. Younger children provided memories of events that occurred at earlier ages than older children. Furthermore, Canadian children produced more memories and had an earlier age of first memory than did Chinese children, with cultural differences in both measures increasing with age. It appears that while adultlike childhood amnesia is still emerging among Canadian children, Chinese children by age 14 already resemble adults. Content of Canadian versus Chinese children's memories reflected an autonomous versus relational self-construal. Results are discussed in terms of sociocultural influences on memory.  相似文献

The aim of Galileo's tidal theory was to show that the tides were produced entirely by the earth's motion and thereby to demonstrate the physical truth of Copernicanism. However, in the Dialogue Concerning the Two Chief World Systems Galileo did not explain some of the most significant aspects of the theory completely. As a consequence, the way the theory works has long been disputed. Though there exist a number of interpretations in the literature, the most widely accepted are based on ideas that are not explicitly articulated by Galileo in the Dialogue. This essay attempts to understand the way the theory functions in terms of Galilean physics. It is an interpretation of the theory based solely on Galileo's arguments--and one that reveals it to have had some unrecognized consequences. This interpretation indicates that Galileo's theory would not have worked in the manner he described in the Dialogue.  相似文献

The present paper focuses on the preparatory courses for the French grandes écoles (CPGEs), which are selective higher education programmes that enable ‘good’ students to bypass mass higher education and study under ‘favourable’ conditions. These CPGEs, originally intended to educate the children of the social and cultural elite, are now accepting young people from more diverse social backgrounds. Our investigation of this ‘new’ student population is based on a survey (1000 students and 350 teachers) and on interviews conducted with students (82) and teaching staff (24). Our research leads us to conclude that under the pretext of democratisation and adaptation to the labour market, CPGEs recruiting these new students are, paradoxically, helping to maintain social stratification.  相似文献

Mobile technologies are becoming more and more prevalent in learning environments. This means that teacher education must keep pace with the use of mobile technologies. Baran (2014) argues that the ‘greatest added value of mobile learning vis-a-vis PC learning lies in the aspects that extend classroom interaction to other locations via communication networks’. (p. 18) This article outlines a pilot study developed to support collaborative working between the English and science pre-service teachers, in which mobile technologies were used to extend students interactions outside the classroom, using iPads in authentic, fieldwork situations.  相似文献

We explored how new Teachers of Color grappled with equity and excellence as they were constructing science teacher identities while learning to teach in a teacher education program committed to equity, justice, and excellence, and eventually teaching in urban schools where inequities and injustices persist. The theoretical framing, compiled from various bodies of literature, weaved together what we consider as essential parts of teacher identity construction and provided a lens with which to examine how conceptions of equity and excellence that the study participants were constructing meshed with their multiple identities, considerations on legitimate knowledge production, and dialectical relationships with which they grappled. Using transcendental phenomenology, we learned from and with three Black and Latinx teachers and their narratives. The teachers intertwined similarly and differently their evolving conceptions of equity and excellence into their evolving science teacher identities as they engaged in forms of contentious local practice and reflected on their experiences as science Teachers of Color teaching predominately Students of Color. Their multiple identities were meshed with histories of larger institutions—science, schooling, and society—and together these were shaping their conceptions of equity and excellence. The intermingling of equity and excellence, which was guiding the curricular and instructional decisions they were making in their classrooms, was also linked to what they considered as legitimate knowledge production in science classes and what counted as knowledge that their students needed to know at different times. The various dilemmas defined by opposing poles with which they were grappling also functioned as scales on which their coordinated equity-excellence unit of meaning was forming. Based on the study, we offer insights into practices that science teacher educators may consider as they prepare new teachers, and work with practicing teachers, to embrace and coordinate equity and excellence in their ever-developing science teacher identities.  相似文献

Using data collected from a recent national survey of Australian first-year students, this paper defines and validates four scales – belonging, feeling supported, intellectual engagement and workload stress – to measure the student experience of university. These scales provide insights into the university experience for both groups and individual students, to assist institutions in supporting and managing successful outcomes for their students. These data highlight the particular importance of a sense of belonging and mitigating workload stress to addressing attrition risk. Many traditional equity groups were found to only differ significantly from ‘traditional’ students on the stress scale. However, these groups potentially contain enormous individual variation, and even the average experiences of these groups reveal that complexity in the engagement, motivation and sense of belonging of students from equity backgrounds. Importantly, the scales presented in this paper can easily be used by practitioners, researchers and institutions to identify risk of attrition at an individual level based on attitudinal factors rather than background or behavioural factors. This may inform university strategy and practice to enhance the student experience and increase retention across the sector.  相似文献
