Growth and maturation impact the selection, development and progression of youth athletes. Individual differences in the growth and maturity may afford a performance advantage, clouding coaches and practitioners’ perceptions regarding current ability and future potential. This may result in the exclusion of talented, yet less physically gifted athletes. Participants were 91 male (n = 47) and female (n = 44) elite British Junior tennis players, 8–17 years of age (12.5 ± 1.9 years). Height and body mass were measured and compared to growth charts; hand-wrist radiographs were taken. Skeletal age (SA) was estimated with the Fels method and contrasted to chronological age (CA). Mean height and body mass of individual players ranged between the 50th and 90th centiles for age and sex. Females were advanced in SA relative to CA (0.3–0.89 years.) from 8 years. Males were average to delayed in maturation from 8 to 12 years, but advanced in SA from 14 to 16 years (0.75–1.23 years). Individual differences in growth and maturation appear to contribute towards the selection of elite junior tennis players, with a bias towards males and females who are advanced in maturation and comparatively tall and heavy for their age. This has important implications for talent identification and development. 相似文献

The aim of this article is to study the possible influence that exercising a representative role at school may have on secondary school students’ willingness to participate politically in society. In order to do this, an analysis was carried out of the answers given by 300 students between 13 and 18 years old, from a school with marked democratic practices, when asked about their experience of democracy at school and their intention to participate politically. The results show that students’ willingness to participate in society by means of conventional actions, such as voting, does not depend directly on whether they have exercised a representative role at school. However, non-conventional actions, such as attending demonstrations or supporting boycotts, does have a meaningful relation with the exercise of representative roles in the school. As a conclusion, we highlight that participating in the representation of the school influences the democratic formation of students and their willingness to participate politically in society, although this influence is more closely related to non-conventional actions, such as strikes, boycotts and demonstrations. 相似文献

Between Transaction and Transformation: The Role
of School Principals as Education Leaders in Spain 总被引:1,自引:0,他引:1
Spain is, together with Portugal, the only OECD country where school principals are democratically elected from the teaching
staff of each primary and secondary school by a School Council, where all members of the school community are represented.
While this unique feature of the Spanish system entails many promises in terms of deep democracy and, equally important, the potential legitimacy of change promoted by school leaders, the reality seems to be somewhat less
romantic. This paper explores the limitations and constraints faced by school principals in Spain to actually perform their
role as school leaders in primary and secondary schools. Based on a major study that we carried out for the National Institute
for Quality and Evaluation (INCE) in 2002, involving more than 20,000 questionnaires and 30 Focus Groups (with teachers, principals,
school inspectors, administrators, education experts and parents), the paper deals with the impact of leadership on school
improvement and change, especially as far as teaching and learning processes are concerned. Despite their democratic legitimacy,
or perhaps precisely because of its unexpected effects, the elected principal in Spain faces constraints which de facto position
himself or herself between a practice of permanent transaction with colleagues and the mounting pressure of transformation and accountability coming from outside the school. Results from this research suggest that such constraints are determining
that the practice of school leadership in Spain is management and maintenance-oriented rather than change-oriented, thus casting
doubts about the very model of school leadership. 相似文献

ABSTRACTThe different technology fields have increased in complexity, especially during the last two decades, giving place to the concept of Complex Technology. An example is Electronics also characterised as a horizontal technology being incorporated in many products and processes of other technological areas. Bloom’s taxonomy of learning objectives and the revised version of Bloom disciples, which have been used by several experts in pedagogy, suffers from a generalist character and are not adapted to technology learning. In this article an engineering learning taxonomy is presented. Also a computer learning assisted tool called ISETL (Integrated System for Electronics Technology Learning) has been developed to facilitate the Electronics fundamentals understanding. ISETL has been evaluated taking into account not only the results of the theoretical assessments but also through the results obtained in the laboratory. These results demonstrate the advantages of this approach and can be depicted by the progressive improvements registered in student performance. 相似文献

Most researchers into bullying agree on its social implications and on some inner aspects of the aggressive situations. Methods of identifying bullying among peers used to be very costly in time and effort. In order to simplify the task, the Bull‐S questionnaire has been elaborated. After its confirmation as a usable instrument in Spanish schools, we attempted to find out whether it could also be a good tool in foreign schools, by applying it to both an English and a Spanish sample. Results showed very high similarity between samples, which allows us to say that the aspects measured by the questionnaire are the same in both samples. First, we did not find significant differences in the extent of bullying in schools. Second, an item‐by‐item comparison showed significant differences between means in only: “Leave out of activities and games.” From a sociometric perspective, rejection is presented as associated with bullying and especially linked to victimisation, and acceptance is associated with those pupils not involved in bullying. Finally, factorial analyses confirmed that variables conformed to a different structure for bullies, for victims, and for not‐involved pupils. These different structures are quite similar in both countries. 相似文献

How should the governance system in a non-membership non-profit organization be designed? This organizational form has no shareholders; instead, donors provide funds. Thus, at the organizational level, the board of directors could have all the power. Under this legal form, who controls the board? If too powerful, boards could misuse resources or distract the organization from its foundational goals. We examine the case of private higher education institutions (HEIs) in Colombia and the balance of power in university governance systems which feature this organizational form. Most HEIs in our sample have a kind of assembly of representatives as the governance body with the highest authority and able to appoint and control the board. We specifically discuss the assemblies’ reason for being, structure, and functions in private HEIs in Colombia. We analyze a total of 204 HEI governance structures and find governance arrangements with the characteristics of an assembly of representatives in 154 (75.9%). Our analysis highlights features in some of these governance bodies that could lead to overly powerful assemblies (e.g., founder donors with tenure for life). Clearly, a proper balance of power is required to avoid rent-seeking behaviors or the pursuit of harmful private non-monetary benefits from assembly members as well as boards. 相似文献

Concern has been expressed recently regarding the presence of a digital divide between majority and minority groups. Surveyed were 226 Hispanic college freshmen enrolled at a doctoral intensive institution in the Southwest regarding their attitudes toward educational uses of the Internet and their uses of technology. Statistically significant differences were found between males and females in their attitudes toward and uses of the Internet and computer technology. Differences were also revealed between students whose primary language spoken at home was English and students whose primary language spoken at home was Spanish in their attitudes toward and uses of the Internet and computer technology. Interestingly, no differences were present between first-generation and non-first-generation college students. Implications of our findings and relationships to existing literature are provided. 相似文献

Distributed ledger technologies (DLTs) such as Blockchain appear to have disruptive economic potential to traditional finance-sector and non-financial markets as the success of crypto currencies demonstrates. While traditional financial and securities markets are highly regulated, DLT transactions and exchanges have so far widely remained unregulated, which potentially poses major threats to individual investors and, via money laundering, terrorist financing, and tax evasion, to society at large. Governments have been taking different approaches to monitoring and regulating the fledgling DLT provision arena. However, the small jurisdiction of Gibraltar, an affluent self-governed and self-financed British overseas territory with a population of 34,000 at the Southern tip of the Iberian Peninsula has taken a proactive approach. What makes this case stand out is that Gibraltar is not only is the first jurisdiction worldwide to regulate general DLT provision, but it is rather using the regulation as a competitive tool and a means for creating new public value. The study inquires the potential benefits and challenges to this particular approach to DLT provision regulation, and it investigates and presents the various facets of public value generation, which might serve as a poster child for fast and smart regulation in the digital age. 相似文献

Measuring the continuum of literacy skills among adults: educational testing and the LAMP experience
Cesar Guadalupe Manuel Cardoso 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2011,57(1-2):199-217
The field of educational testing has become increasingly important for providing different stakeholders and decision-makers with information. This paper discusses basic standards for methodological approaches used in measuring literacy skills among adults. The authors address the increasing interest in skills measurement, the discourses on how this should be done with scientific integrity and UNESCO??s experience regarding the Literacy Assessment and Monitoring Programme (LAMP). The increase in interest is due to the evolving notion of literacy as a continuum. Its recognition in surveys and data collection is ensured in the first commitment in section?11 of the Bel??m Framework for Action. The discourse on how measurements should be carried out concerns the need to find valid parsimonious approaches, also their relevance in different institutional, cultural and linguistic contexts as well as issues of ownership and sustainability. Finally, UNESCO??s experience with LAMP shows how important addressing these different issues is in order to equip countries with an approach that is fit for purpose. 相似文献

This investigation analyzed the relation between cognitive functioning and mathematical achievement in 114 students in fourth, fifth, and sixth grades. Differences in cognitive performance were studied concurrently in three selected achievement groups: mathematical learning disability group (MLD), low achieving group (LA), and typically achieving group (TA). For this purpose, performance in verbal memory and in the PASS cognitive processes of planning, attention, and simultaneous and successive processing was assessed at the end of the academic course. Correlational analyses showed that phonological loop and successive and simultaneous processing were related to mathematical achievement at all three grades. Regression analysis revealed simultaneous processing as a cognitive predictor of mathematical performance, although phonological loop was also associated with higher achievement. Simultaneous and successive processing were the elements that differentiated the MLD group from the LA group. These results show that, of all the variables analyzed in this study, simultaneous processing was the best predictor of mathematical performance. 相似文献
