Since its creation in 1958, the European Social Fund (ESF) has played a major role in supporting the development of vocational training in the Member States. However, compared to other, more recently launched, EU programmes and initiatives in the area of education and training, the ESF has not made a significant contribution to the debate about European cooperation in this field. This article argues that the ESF has made a mistake in this respect. It also seeks to illustrate and analyse the important changes that the ESF has undergone over the years in addressing the issue of vocational education and training (VET) and to demonstrate that it has substantial resources, in terms of money and experience, that can be used to adapt education and training systems to labour market requirements and to the needs of a knowledge-based economy. The article places a deliberate, though not an exclusive, emphasis on vocational education and training for young people and on the extension of transnational cooperation within the framework of the ESF.  相似文献

Teachers choosing between different models to facilitate students’ understanding of an abstract system must decide whether to adopt a model that is simplified and striking or one that is realistic and complex. Only recently have instructional technologies enabled teachers and learners to change presentations swiftly and to provide for learning based on multiple models, thus giving rise to questions about the order of presentation. Using disjoint individual growth modeling to examine the learning of astronomical concepts using a simulation of the solar system on tablets for 152 high school students (age 15), the authors detect both a model effect and an order effect in the use of the Orrery, a simplified model that exaggerates the scale relationships, and the True-to-scale, a proportional model that more accurately represents the realistic scale relationships. Specifically, earlier exposure to the simplified model resulted in diminution of the conceptual gain from the subsequent realistic model, but the realistic model did not impede learning from the following simplified model.  相似文献
