Abstract

The current network society, with its primacy of information and communication technologies, is challenging the higher education model. The needs and expectations of today’s students differ from those of students in the past, and educational practices should adapt to modern times. But what changes will we see in the relationship between societal transformation and the higher education system? In this research paper, we set out a quantum-based approach in order to analyze this relationship and to advance the understanding about the role that distance education will play in the future. Under this perspective, we provide an illustration that allows for the representation and evaluation of future scenarios.  相似文献

The paper we present here is part of the International Successful School Principalship Project (ISSPP), which is designed to analyse the characteristic traits of successful leadership in different contexts and countries [Day, C., and K. Leithwood. 2007. Successful School Leadership in Times of Change. Dordrecht: Springer-Kluwer; Day, C., and D. Gurr. 2014. Leading School Successfully. Stories from the Field. London: Routledge]. One subgroup of the Spanish research team participating in the ISSPP at the University of Granada has contributed to the project by carrying out a comparative study of the type of leadership for learning at four secondary schools in disadvantaged contexts. Following ISSPP data collection protocols and using a category system specially designed to analyse the leadership for learning carried out by the four principals, the results show that four secondary schools have principals with a similar traits, dispositions and value systems; however, the secondary schools with the best academic results employed practices and strategies more closely associated with leadership for learning than schools with poorer academic results. The data provided by this study confirm the traits and strategies that the ISSPP has been identifying in successful principals in disadvantaged contexts in various countries. It also serves as a source of reflection and discussion on the type of leadership for learning present in some disadvantaged secondary schools in Spain.  相似文献

The present study examined psychosocial adjustment in the following four groups of students: victims, bullies, bully/victims and a control group of adolescents not involved in bullying or victimization problems. Psychosocial adjustment was measured considering as indicators: level of self-esteem, depressive symptomatology, perceived stress, feeling of loneliness, and a general measure of satisfaction with life. Participants (N=1319) were aged from 11 to 16 (47% male) and drawn from seven state secondary schools in Valencia (Spain). ANOVAs revealed significant differences among groups, reporting adolescents not involved a general better psychosocial adjustment; they had higher levels of self-esteem and satisfaction with life, and lower levels of depressive symptomatology, perceived stress and feeling of loneliness. The scores for this group were equivalent to those of bullies with respect to self-esteem, depressive symptomatology and loneliness. However, bullies perceived more stress and expressed less satisfaction with life, as did the other two groups, namely victims and bully/victims. Victims reported the strongest feelings of loneliness. Bully/victims seemed to share characteristics with both bullies and victims, though showing more similarities with the latter and a general poor psychosocial profile.  相似文献

This study aimed to elucidate the mechanisms of melatonin to manage neurological damage in Alzheimer’s disease (AD) induced in ovariectomized rats. Forty adult female rats were enrolled in our study and were classified as; gonad intact control, ovariectomized control group, ovariectomized rats received melatonin, ovariectomized rats injected with AlCl3 to induce AD and AD-induced rats treated with melatonin. Hydrogen peroxide (H2O2), malondialdehyde (MDA), total antioxidant capacity (TAC), superoxide dismutase (SOD), catalase (CAT), B cell lymphoma 2 (Bcl-2), brain derived neurotrophic factor (BDNF), acetylcholinesterase (AchE) and acetylcholine (Ach) were estimated in the brain tissues of the different groups. Treatment of AD-induced rats with melatonin produced marked improvement in the most studied biomarkers which was confirmed by histological investigation of the brain. In Conclusion, melatonin significantly ameliorates the neurodegeneration characteristic of AD in experimental animal model due to its antioxidant, antiapoptotic, neurotrophic and anti-amyloidogenic activities.  相似文献

ABSTRACT

This paper investigates the evolution of leadership for learning that has occurred in four secondary schools located in disadvantaged contexts in the province of Granada (Spain) over a period of 2 years, performing a comparative analysis on the values, qualities and strategies that characterize their principals during the academic years 2013–2014 and 2015–2016. The investigation uses case studies and conducts interviews with principals, teachers and education administrators. It is supported by the group-case method, as well as the longitudinal prospective method. The results show that only one of these principals has maintained a leadership aimed at learning and achievement of all students in the school, at the same time as students’ academic results have been improving. This paper concludes by providing information on values, qualities and strategies of successful leadership in disadvantaged contexts in Spain that distinguish them from other less successful leaders.  相似文献

This article is part of the International Successful School Principalship Project (ISSPP) and aims to analyse the success factors of two Spanish secondary school principals working in the line of social justice in challenging contexts. The factors are arranged in traits and beliefs of principals and in the strategies they used to bring successful leadership. The article concludes by showing a model of leadership that emphasizes both personal and professional characteristics of principals and their central role as agents of social change.  相似文献

Abstract

The aim of this study was to analyse the relationship between sociometric types, behavioural categories and academic achievement in a sample of 1,349 compulsory secondary education students (51.7% boys), ranging in age from 12 to 16 years. The students’ sociometric identification was performed by using the Programa Socio and academic performance was measured by school marks provided by teachers in the subjects of Spanish language, mathematics and average academic performance. The results show that sociometric types were significant predictors of academic achievement, as students who were rated positively by their peers (popular, leaders, collaborators and good students) were more likely to have high academic achievement (in mathematics, Spanish language and average academic achievement) than students rated negatively by peers (rejected-aggressive, rejected-shy, neglected and bullies).  相似文献
