ABSTRACT— In this article, we discuss the role of rostral prefrontal cortex (approximating Brodmann Area 10) in two domains relevant to education: executive function (particularly prospective memory, our ability to realize delayed intentions) and social cognition (particularly our ability to reflect on our own mental states and the mental states of others). We review evidence from neuropsychology and neuroimaging suggesting the involvement of rostral prefrontal cortex in these domains and discuss an overarching framework that seeks to characterize these functions in terms of attentional selection between perceptual and self-generated information. In addition, we present neuroimaging evidence in adults suggesting considerable functional specialization within this region. We conclude by discussing implications of these results for education and suggest directions for further research. 相似文献

This study examined a moderated mediation model among 314 Black adolescents aged 13–18. The model included general coping strategies (e.g., active, distracting, avoidant, and support‐seeking strategies) as mediators and racial identity dimensions (racial centrality, private regard, public regard, minority, assimilationist, and humanist ideologies) as moderators of the relation between perceived racial discrimination and depressive symptoms. Moderated mediation examined if the relation between perceived racial discrimination and depressive symptoms varied by the mediators and moderators. Results revealed that avoidant coping strategies mediated the relation between perceptions of racial discrimination and depressive symptoms. The results indicated that avoidant coping strategies mediated the relation between perceived racial discrimination and depressive symptoms among youth with high levels of the minority/oppressive ideology. 相似文献

In 1713, the scientific instrument-maker Jakob Leupold published designs for three machines were the first attempt to design machinery with internal moving parts that replaced human agency in creating original images. This paper first analyzes his text and engravings in order to explain how he proposed to do this, given contemporary materials and command of physical forces. Next, it characterizes the devices as a transition from concepts of incision to concepts of mirroring, taken as models of the history of mechanical reproduction. And finally, Leupold’s replacement of the sighting grid with differential gears points to a set of problems appearing in contemporary philosophy represented in Rococo artistic production of this period as well. Taking the proposed devices in context, they help to theorize the complex notions of creative activity in Rococo visual culture. Taken as an episode in the history of communications, they instance the development of conceptions of personhood and of physical forces at stake in the invention of automated media. 相似文献

This study investigated the mental representations of metallic bonding and the malleability of metals held by three male students aged 14–15 (Year 10) who were attending a Hong Kong school. One student was selected by their chemistry teacher as representing each of the highest, the medium, and the lowest level of attainment in chemistry in a school that admitted students of average general attainment. The students were interviewed and their understandings probed through their provision of drawings and their interpretation of the diagrams that had been previously used by their teacher. Dual coding theory was used to interpret the relative significance of visual and verbal input and the interaction between the two for their understanding. There was evidence that students relied on verbal recall in providing their initial understandings and showed an appreciation of the nature of the structural components of the electron-sea model of metallic bonding. However, they varied in terms of their appreciation of the electrostatic force which was responsible for the malleability of metals. The study suggests that a clearer understanding of the electrostatic force involved can be attained when students experience visual and verbal representations simultaneously, a conclusion supported by dual coding theory. Principles for good practice in using diagrams in teaching are discussed. 相似文献

Enigmas in School Science: students’ conceptions for scientifically associated words 总被引:1,自引:0,他引:1
Master's students were involved in the design, and later the administration, of a questionnaire for 500 junior secondary students in Botswana and Lesotho, to buildup a picture of student perceptions of science and technology. Responses to mainly open‐ended questions were categorised according to key phrases mentioned by the students. There was some confusion over the differences between science and technology, but they were overwhelmingly perceived as subjects appropriate to both sexes. Science and technology were seen in broad socio‐economic terms, enabling people to cope in the modern world, gain employment in both the formal and informal sectors, and contribute towards national development. Although science and technology were judged to have enhanced the quality of life, they had introduced conflicts into traditional beliefs and cultures, in part as a result of increasing female emancipation. The attitudes of the students towards the two subjects, and to the impact they have had on everyday life, were congruent with the philosophical aims of the science and technology syllabuses of both countries and with global initiatives such as Project 2000 +. 相似文献

Course design,teaching method and student epistemology 总被引:3,自引:0,他引:3
Previous research into student learning in departments of higher education has shown that links can be established between students' approaches to studying and their perceptions of the academic environment. It has also been found that students with differing study orientations are likely to define effective teaching in ways which reflect those orientations. The study reported here began by identifying different types of student epistemology and then investigated those factors within the academic environment which appeared to influence their incidence. Employing a naturalistic methodology-observations, interviews and case studies - the study was conducted in four departments in one institution of higher education: two arts and two science. Through a process of progressively focusing upon emergent issues, the study evolved through three stages, culminating in a model of the factors appearing to influence the development of student epistemology. It is found that the development of student epistemology is influenced by the interrelated factors of student learning approach, perception of the academic environment and lecturers' theories of teaching, which tends to uphold previous findings. It is also found, however, that students' conceptions of knowledge and their learning approaches are influenced by the ways in which knowledge is structured and presented within departments. Most particularly, a relationship was found between historical and philosophical studies, the methods of teaching them, and the development of student epistemologies. 相似文献
