The concept of competence is a recent introduction into the curricula of the Spanish education system, and applies to vocational training and university, but also to basic education. In both cases, the meaning and use of the term have differed, sometimes giving rise to confusion. There can be no doubt, however, that this incorporation has been of significant impact. On the one hand, it has generated considerable debate between those who consider the concept to respond to economistic arguments, removed from educational realities, and those who believe it to have a transformation potential that cannot be ignored. On the other, incorporation of the concept is leading to a series of modifications in school practices and in teaching and learning with whose consequences we are not yet acquainted. This article analyses the situation created by the introduction of key competences in Spanish compulsory education and seeks to gauge the potential this offers for improving opportunities for success at school. The authors believe that key competences are a reformulation of educational intentions, whose consequences for schools and teaching practices largely depend on the new interpretation of learning in the light of different approaches and research traditions.  相似文献

Higher education is a mainstay in the development and support of the economic, social and cultural development of the global society. Throughout history, academic institutions have sought to respond to the demands of endlessly changing and evolving environmental conditions. However, in the 21st century, a number of significant factors are changing the higher education landscape and challenging higher education institutions (HEIs) to interpret the vital needs of contemporary society to stimulate and enhance student development. Student development is an all-embracing concept that involves research focusing on students from recruitment to placement. Assuming that meeting student needs and stimulating and enhancing their development are crucial challenges for higher education institutions worldwide, the article focuses on a national study in Portugal designed to measure students’ expectations and satisfaction with their experience. On the basis of a nationwide survey, it examines these in the various types of higher education institutions in Portugal.  相似文献

Adapting support contingently to student needs by first diagnosing their current understanding, that is, scaffolding, is considered a key aspect of excellent teaching. The use of classroom scaffolding is rare, however. We therefore investigated the benefits to teachers of a professional development program that was based upon a model of contingent teaching (MCT) with the following 4 steps: diagnostic strategies, checking of diagnoses, giving contingent support, and checking of student learning. In our experimental study, 17 of 30 teachers participated in this program. All of the teachers (prevocational education; teaching social studies) taught the same 5-lesson project on the European Union. The frequency and quality of their use of the 4 steps from the MCT were then compared. The teachers who worked with the MCT increased their teaching quality more than the teachers who did not participate, especially with regard to the steps of contingent teaching. They also showed more complete cycles of contingent teaching at postmeasurement than the other teachers. Less successful teachers showed a tendency to provide less support because they mistakenly thought that prompting was not part of scaffolding. Future scaffolding research and professional development efforts aimed at promoting scaffolding can benefit from the MCT, provided that teachers’ understanding of scaffolding is closely monitored.  相似文献

The purpose of this paper is to analyse and describe the topological properties of the institutional and national collaboration network from the profiles extracted from Google Scholar Citations (GSC). 19,912 unique profiles with “co-authors” were obtained from a web crawl performed in March 2012. Several statistical and network analysis techniques were used to map and analyse these collaboration relationships at the country and institution level. Results show that The United States dominates the world scientific map and that every research institution is grouped by national, geographical and cultural criteria. A clustering phenomenon based on the self-similarity and fractal properties of scale-free networks is also observed. We conclude that GSC is a suitable tool for collaboration studies only at macro level between countries and institutions.  相似文献

The purpose of this study was to measure and characterise the distances covered by Brazilian professional futsal players. The trajectories of 93 players during five matches were obtained using an automatic tracking method. The distances covered were analysed for different game conditions: over the entire game and during the times when the ball was out of play and in play separately. When the entire game was considered, the results showed that there was a reduction in the total distance covered per minute from the first [median ± IQR (interquartile range): 97.9 ± 16.2 m/min] to the second half (median = 90.3 m/min; IQR = 12.0), and when only the in-play time was considered (first half: 136.6 ± 17.2 m/min; second half: 129.2 ± 16.7 m/min). The percentage of distance covered in the standing and walking velocity range was higher in the second half than in the first when considering the entire game (30.8% and 28.0%, respectively) and during the in-play time (19.3% and 16.2%, respectively). In conclusion, this study verified that futsal players reduced the physical performance during the second half.  相似文献

This paper aims to present a comprehensive proposal for project scheduling and control by applying fuzzy earned value. It goes a step further than the existing literature: in the formulation of the fuzzy earned value we consider not only its duration, but also cost and production, and alternatives in the scheduling between the earliest and latest times. The mathematical model is implemented in a prototypical construction project with all the estimated values taken as fuzzy numbers. Our findings suggest that different possible schedules and the fuzzy arithmetic provide more objective results in uncertain environments than the traditional methodology. The proposed model allows for controlling the vagueness of the environment through the adjustment of the α-cut, adapting it to the specific circumstances of the project.  相似文献
