In Spain, the exercise of choice by parents of a suitable school for their children is not practised by all families in the same way. The evidence shows that an increasing social polarisation and a substantial disequilibrium in schooling are taking place in compulsory education. There is a high concentration of immigrant students in public schools in contrast with what happened in the centros concertados (private schools with public funding). This situation is especially unbalanced in some Autonomous Communities, such as the Community of Madrid, Catalonia, Valencia and Andalusia. The inequalities in the distribution of students in the network of public schools and private schools financed by public funds are producing significant responses from parents, teachers, experts, and also from other social groups. Some of the proposals made by different experts and by the Spanish Ministry of Education are analysed in order to reach to a quality education in more equitable conditions for all students. 相似文献

ABSTRACTEvidence exists that American institutions of higher education are well-entrenched in the consideration of mechanisms for supporting the implementation of Open Educational Resources (OER) and alternative textbooks. Literature reveals that developing and implementing OER is a significant undertaking in terms of time and human resources. This study deploys content analysis of a sample of United States regionally based higher education institutional websites to determine the current state of institutional support mechanisms to implementers just embarking on the OER journey. Findings reveal that institutions have made strides in the development of faculty mini-grants and stipends with guidelines, proposal checklists, and weighting mechanisms to inform decision making. However, due to widespread language across the stratified sample emphasising award pool and individual limits, it is clear that OER funding is still seeking wider support as a permanent funded resource. Sponsorship of institutional OER initiatives seems split between institutional library functions and teaching and learning centres. Other issues, such as ownership and licensing, are significantly underdeveloped in field implementation or fall in a large continuum of practices. Recommendations of shared responsibility and use of data driven initiatives are provided that may improve institutional support of faculty OER adoption, adaption and creation. 相似文献
