The current investigation aims at assessing the effectiveness of an intervention program designed to enhance self-regulated learning (SRL) strategies at the university level, with students from different cultural, linguistic, and educational backgrounds. The central tool of the program is a set of letters in which a fictional first-year student describes his experiences as an SRL student. The program was implemented in four universities in different countries and continents (Portugal, Spain, Chile, and Mozambique), with an experimental group and a comparison group at each university (263 students from experimental groups and 247 from comparison groups). Findings display the effectiveness of the program in enhancing a set of motivational variables related to the study process and the use of SRL strategies. Data were consistent across the different cultural and academic contexts in which the program was implemented. The implications of these findings for university administrators and faculty are discussed. 相似文献

This article seeks to illustrate how a research study that claims to be inclusive should incorporate into its development, decisions of methodological flexibility that enable voice to be given to all participants regardless of their personal conditions. The changes carried out in the techniques, procedures or in the kind of questions used in the research, illustrate how young persons can be involved in the building of scientific and academic knowledge that is being generated about them. This work forms part of a more extensive line of inquiry that started a number of years ago by two Spanish universities (Cantabria and Seville). 相似文献

Queries submitted to search engines can be classified according to the user goals into three distinct categories: navigational, informational, and transactional. Such classification may be useful, for instance, as additional information for advertisement selection algorithms and for search engine ranking functions, among other possible applications. This paper presents a study about the impact of using several features extracted from the document collection and query logs on the task of automatically identifying the users’ goals behind their queries. We propose the use of new features not previously reported in literature and study their impact on the quality of the query classification task. Further, we study the impact of each feature on different web collections, showing that the choice of the best set of features may change according to the target collection. 相似文献

The aim of this article is to outline and assess an educational intervention programme targeted at improving the skills of
families and the personal and social development of children living in situations of grave social vulnerability. The sample
comprised 10 families during the first phase of the intervention and six during the second. The design, intervention and assessment
process of this study was carried out in two phases over a period of a year and a half. For both phases, three different groups—of
men/fathers, women/mothers and children—were established. Study variables (parenting skills and children’s personal and social
development) were evaluated before and after the intervention in every group, as well as during the entire process. The results,
taking into account the improvements reported by all the participants (social workers, group monitors, fathers, mothers, children)
show that inter-professional involvement and coordination at all phases of the intervention is vital in order to achieve small
but significant improvements. 相似文献

Research has highlighted that inquiry-based learning (IBL) instruction leads to many positive student outcomes in undergraduate mathematics. Although this research points to the value of IBL instruction, the practices of IBL instructors are not well-understood. Here, we offer a characterization of a particular form of IBL instruction: inquiry-oriented instruction. This characterization draws on K-16 research literature in order to explicate the instructional principles central to inquiry-oriented instruction. As a result, this conceptualization of inquiry-oriented instruction makes connections across research communities and provides a characterization that is not limited to undergraduate, secondary, or elementary mathematics education. 相似文献

Object permanence was assessed for cats and dogs, using tasks analogous to those typically employed for human infants. Neither species solved all of the problems correctly when rewarded only by the discovery of a hidden toy. However, both species showed that they had fully developed concepts of object permanence when the problems were changed so that the animals had to search for hidden food in an odor-control procedure. These results indicate that sensorimotor intelligence is completely developed in these nonprimates. 相似文献

The present study explores the development and promotion of reading comprehension in primary school students, in the context of the implementation of an educational programme called ‘Learning Together’ (LT). The programme, which centred on collaborative learning activities, was designed to promote oral and written communication in primary school Mexican children. Analyses revealed that children who participated in the LT programme, in comparison with students in a control condition, produced higher‐quality written summaries of texts they had read, both when working in teams and when working individually. This suggests that the LT participants appropriated and transferred the text comprehension strategies promoted, so that they could apply these strategies effectively not only in collaborative contexts but also independently, that is, in a self‐regulated and autonomous fashion. The theoretical and practical implications of the work are discussed in relation to understanding and promoting oracy and literacy processes in primary school students. 相似文献

The aim of this study was to analyse the effect of stimulus change timing on reaction response time parameters, horizontal velocity of the centre of mass (CM) and precision during offensive actions in fencing. Twelve fencers from the Spanish National Foil Team were included in the study. Two 500 Hz force plates were used to register the horizontal component of the reaction force while a 3D video camera set at 250 Hz recorded the spatial position of 11 body markers and a projector connected to a programmed stopwatch projected a moving target (stimulus) on a screen. When the circle (target) appeared in the centre of the plastron, fencers had to execute a step-forward-lunge as fast as possible, trying to touch the circle with the tip of the foil. During the lunge, the position of the target could randomly shift or not to three different positions. The stimulus change was performed randomly at four different times with a progressive delay. The results show that target changes did not have any effect when they occurred at the beginning of the movement sequence. However, when the target change was delayed, reaction and movement times increased and the technical execution of the lunge changed, leading to more errors. 相似文献

This paper explores new data sources on multilateral trade in films among EU countries and with the USA in offline cinema and in online video-on-demand distribution. We observe variations in trade patterns across countries and films and explore how they affect cultural diversity. We find that the EU film market is highly fragmented and cross-border film availability in cinema is low. We explore different aspects of the cultural discount hypothesis by means of a standard Helpman and Krugman (Market structure and foreign trade. Increasing returns, imperfect competition, and the international economy, MIT Press, Cambridge, 1985) trade model with economies of scale and a two-stage Heckman (Econometrica 47(1):153–161, 1979) estimation procedure. Our results show that cultural distance, success in the home market and the size of the film budget influence trade of films between countries. US films have a lower propensity to get into export markets, relative to their success in the home market. Consumer demand for imported films is relatively smaller in large EU economies, except for films imported from the USA that are only marginally affected. We also show that trade patterns in online film distribution are not fundamentally different. As online distribution occurs downstream from theatrical release, online distributors can benefit from cinema market experience to make a better selection of films. This results in a lower impact of domestic market shares on online trade patterns. 相似文献
