Many mathematics education researchers have suggested that asking learners to generate examples of mathematical concepts is
an effective way of learning about novel concepts. To date, however, this suggestion has limited empirical support. We asked
undergraduate students to study a novel concept by either tackling example generation tasks or reading worked solutions to
these tasks. Contrary to suggestions in the literature, we found no advantage for the example generation group on subsequent
proof production tasks. From a second study, we found that undergraduate students overwhelmingly adopt a trial and error approach
to example generation and suggest that different example generation strategies may result in different learning gains. We
conclude by arguing that the teaching strategy of example generation is not yet understood well enough to be a viable pedagogical
recommendation. 相似文献

Innovating firms are likely to face several challenges and experience different types of barriers. In this paper we argue that it is necessary to distinguish between two kinds of barriers to innovation. The first corresponds to what we describe as revealed barriers and reflects the degree of difficulty of the innovation process and the learning experience consequent on the firm engaging in innovation activity. The second type of impediment, which we label deterring barriers, encompasses the obstacles that prevent firms from committing to innovation. We use data from the 4th UK Community Innovation Survey (CIS4) to investigate the relationship between firms’ engagement in innovation and their assessment of the barriers to innovation. We show that the relationship is curvilinear in the case of costs and market barriers. These results have important implications for innovation policy and innovation management. 相似文献

This study aims to analyse artistic understanding in primary and secondary education and the relationship between this understanding and motivational characteristics such as goal orientation, engagement in art activities and attitude to art education at school, which determine (according to prior research) learners' academic achievement, in this case the achievement of a group of young students aged between 10 and 17. A positive relationship was hypothesised between artistic understanding and achievement goals, engagement in art activities and attitudes towards art education, respectively. The results obtained partially support this hypothesis, since a statistically significant relationship was observed between artistic understanding and achievement goals, and the significant relationships hypothesised between artistic understanding and both engagement in art activities and attitudes to art education are largely supported by the findings of this study. 相似文献

We pursue the numerical implementation of a boundary controllability problem for the 1D wave equation based on a recent variational approach to deal with such situations that consists in analyzing an error functional defined for feasible functions complying with appropriate initial, boundary, and final constraints. The nature of such scheme, as a minimization process for a certain error functional, leads to a natural numerical implementation by using typical descent algorithms. Our aim here is to explore the basic ingredients to set up such practical numerical approximations which allow us to address linear and semilinear equations with the same numerical scheme. 相似文献

The aim of this research is to achieve a better understanding of the processes underlying knowledge transfer (KT) in social sciences and humanities (SSH). The paper addresses: first, the extent of SSH research groups’ engagement in KT and the formal KT activities used to interact with non-academic communities; and second, how the characteristics of research groups may influence engagement in various types of KT. The empirical analysis is at research group level using data derived from a questionnaire of SSH research groups belonging to the Spanish Council for Scientific Research (CSIC). We find that KT activities are based on relational rather than commercial activities. The most frequent relational activities in which SSH research groups engage are consultancy and contract research. We find also that the characteristics of research groups (e.g. size and multidisciplinarity) and individuals (e.g. academic status and star scientist) are associated with involvement in KT activities and that a deliberate focus on the societal impacts and relevance of the research conducted is strongly related to active engagement of research groups in all the modes of KT considered in this study. From a managerial perspective, our findings suggest that measures promoting a focus on the societal impact of research could enhance research groups’ engagement in KT activities. 相似文献

In this paper we examine state and indigenous education in Bolivia. Focusing on debates about the hidden curriculum, we conceptualize the school as a political space where tensions between the overlapping jurisdictional powers of the hispanicizing state and indigenous authorities are played out. Our analysis of these tensions highlights the contested way in which indigenous educational policy is negotiated in Bolivia and points to the importance of the deep structures of the hidden curriculum in constructing the school as a territorial authority and a site of struggle in indigenous communities. Using the communities of Raqaypampa, Cochabamba as a case study, we show how local struggles over indigenous education in the 1980s and 1990s became scaled up to influence national educational policy and donor intervention strategies in Bolivia. 相似文献

The growing awareness of serious difficulties in the learning of energy issues has produced a great deal of research, most
of which is focused on specific conceptual aspects. In our opinion, the difficulties pointed out in the literature are interrelated
and connected to other aspects (conceptual as well as procedural and axiological), which are not sufficiently taken into account in previous research. This paper aims to carry
out a global analysis in order to avoid the more limited approaches that deal only with individual aspects. From this global
analysis we have outlined 24 propositions that are put forward for debate to lay the foundations for a profound reorientation
of the teaching of energy topics in upper high school courses, in order to facilitate a better scientific understanding of these topics, avoid many students’ misconceptions and enhance awareness of the current situation of planetary
emergency.
This paper has been conceived as a contribution to the Decade of Education for Sustainable Development, established by the
UN General Assembly for the period 2005–2014. 相似文献

This article tests a longitudinal model of the antecedents and consequences of changes in identification with indigenous (Mapuche) among indigenous and nonindigenous youth in Chilean school contexts over a 6‐month period (633 nonindigenous and 270 Mapuche students, Mages = 12.47 and 12.80 years, respectively). Results revealed that in‐group norms supporting contact and quality of intergroup contact at Time 1 predicted student's changes in Mapuche identification at Time 2, which in turn predicted changes in support for adoption of Chilean culture and maintenance of Mapuche culture at Time 2; some of the relationships between these variables were found to be moderated by age and ethnicity. Conceptual and policy implications are addressed in the Discussion . 相似文献
