In three experiments, the distribution and malleability of infant visual attention were studied in 5-month-olds (N = 72) while they inspected large geometric designs. In Experiment 1, we established that infants maintained their distribution of attention from a pretest to a familiarization phase. We also replicated and extended our previous findings that infants who examined targets with briefer, more numerous looks and shifts-short lookers-had novelty scores above chance, whereas long lookers demonstrated chance responding. In Experiment 2, different portions of the display were successively illuminated with red light. This manipulation induced long lookers to scan like short lookers during familiarization; they then showed novelty scores well above chance. A third experiment ruled out the simple presence of a red light as the source of this effect. In sum, then, these results suggest that the distribution of attention is malleable, and that a broader distribution of attention, as reflected in briefer and more numerous looks and shifts, can improve processing.  相似文献

Preconceptions of first‐year university students of the constituents of matter and the notions of acids and bases were investigated on a total of 400 students. The procedure used consisted of free interviews, semi‐structured interviews and questionnaires.

It was found that the constituents of matter were well known to students, but that interactions between these constituents were either totally unknown or were the subject of severe misconceptions. The students’ knowledge tended to be qualitative and formal, with a worrying lack of connection with everyday life.  相似文献

Abstract

In this paper I contrast conceptions of self from two perspectives: an individualistic orientation and a communitarian approach. In doing so, the philosophical justification is Wittgenstein’s idea that individualism is produced and reinforced as a way of being, thinking and interacting in community. With this contextual frame, I argue that we are shaped by the language practices of our community to ascribe meaning and interpret our own relationships with others through our language lexicon and grammar. To illustrate the communitarian perspective I refer to Māori perspectives in which connectedness is axiomatic: in particular the concepts of whanaungatanga and whakapapa, as described by Ka’ai and Metge. On the basis that such concepts are predicated on language use, I suggest that we can learn the grammar of engagement in a discursive context that emphasises connectedness just as easily as in one which is founded on separateness. I argue that interacting with an other is to engage with the ideas, beliefs, and values that shape their language, even as we expose our own. Engaging between individualistic and communitarian understandings is presented as learning to bridge language gaps between different social constructs and understandings of reality.  相似文献

This paper investigates the role of government R&D subsidy programs in stimulating knowledge spillovers. R&D subsidies are an effective public policy instrument when knowledge spillovers exist yet ex ante it is difficult to identify projects that have the greatest potential to increase innovation and economic growth. This paper derives a set of project and firm attributes that the literature finds generate knowledge spillovers and uses data on project proposals to estimate the degree to which a government R&D program conforms. We find that projects that were awarded R&D subsidies were more likely to have attributes such as participation in new research joint ventures and connections to universities and other firms. Following the post-award activities of firm, we find that receipt of a government R&D subsidy increased the funding from other sources when compared to firms that were not awarded funding.  相似文献

Mathematical task design has been a central focus of the mathematics education research community over the last few years. In this study, six university teacher educators from six different US institutions formed a community of practice to explore key aspects of task design (planning, implementing, reflecting, and modifying) in the context of comparing fractions using reasoning and sense-making. By presenting results of their implementation of two tasks with 63 prospective elementary teachers across three institutions and their reflective analysis of the implementation, the authors highlight the importance of collecting and analyzing data and reflecting on this analysis to inform the redesign of tasks. The authors also found that considering different types of tasks (problem solving vs. problem posing) helps illuminate different aspects of prospective elementary teachers' understanding, which can inform task redesign. Finally the authors contribute to the knowledge base on reasoning strategies for comparing fractions and prospective elementary teachers’ knowledge of these strategies.  相似文献

The education of children with behavioural difficulties is under scrutiny from various quarters. The provision of specialised school environments isbeing questioned and, at the same time, there is pressure to minimise the exclusion of disruptive pupils. The study reported in this article lookedat a group of children whose behaviour had prompted placement in a school for emotionally and behaviourally disordered (EBD) pupils. The results showed the overall rate of psychiatric disturbance in the group was 86% and, in particular, that the rate of Attention Deficit Hyperactivity Disorder (ADHD) was 70%. These findings suggest that a significant minority of disruptive pupils may have their difficulties compounded by the presence of ADHD, and raises the question of whether specific screening processes should be established for such pupils.  相似文献
