ABSTRACT The aim of this article is to examine how EU lifelong learning policies are trying to reach the vulnerable by looking at what measures against social exclusion they offer and how equitable these measures are. It is a qualitative study that focuses on policy documents that form the European Union’s legal and political frameworks of reference in the lifelong learning area since 1992. The document analysis has been complemented by semi-structured interviews with EU lifelong learning experts. The findings show that early school leavers and migrants are the main target groups in the policies, leaving many other groups at risk of being excluded from learning opportunities. There is not enough attention to measures addressing wider social phenomena. There is also an overemphasis on basic skills which are understood in a very narrow way as literacy and numeracy when referring to the vulnerable. We argue that a greater variety of measures as well as better targeted measures are needed to address the multiple and complex needs of the vulnerable. Such measures would allow a broader understanding of lifelong learning where those that are hardest to reach are offered learning opportunities independent of their personal and social circumstances 相似文献

The purpose of this study is to explore key factors that impact the college transition of aspiring underrepresented minority
students in the biomedical and behavioral sciences, in comparison with White, Asian students and non-science minority students.
We examined successful management of the academic environment and sense of belonging during the first college year. Longitudinal
data were derived from the Higher Education Research Institute’s (HERI) 2004 Cooperative Institutional Research Program (CIRP)
Freshman Survey and the 2005 Your First College Year (YFCY) Survey. Using a reformulation of the integration model (Nora,
Barlow, and Crisp, 2005), we find concerns about college financing, negotiating family support and responsibility, and campus
racial dynamics (perceived and behavioral) affect student adjustment and sense of integration in the first year.

Most universities use Information Systems (IS) to perform their daily administrative activities (student enrollment, data
files, accountancy, etc.), and an integrated Learning Management System (LMS) to support teaching and learning. However, although
a lot of effort has been put into deploying these computerized systems, the data that they provide are not fully exploited
from an educational perspective. In this paper we describe a case in which these data have been used to identify relevant
relations between the general use of the LMS, the existence of teaching innovation programs and the quality of education.
The method used can be easily generalized and employed in other different contexts, to derive meaningful information on the
impact that some variables may have over others. 相似文献

Whereas emerging technologies, such as touchscreen tablets, are bringing sensorimotor interaction back into mathematics learning activities, existing educational theory is not geared to inform or analyze passages from action to concept. We present case studies of tutor–student behaviors in an embodied-interaction learning environment, the Mathematical Imagery Trainer. Drawing on ecological dynamics—a blend of dynamical-systems theory and ecological psychology—we explain and demonstrate that: (a) students develop sensorimotor schemes as solutions to interaction problems; (b) each scheme is oriented on an attentional anchor—a real or imagined object, area, or other aspect or behavior of the perceptual manifold that emerges to facilitate motor-action coordination; and (c) when symbolic artifacts are introduced into the arena, they may both mediate new affordances for students’ motor-action control and shift their discourse into explicit mathematical re-visualization of the environment. Symbolic artifacts are ontological hybrids evolving from things with which you act to things with which you think. Students engaged in embodied-interaction learning activities are first attracted to symbolic artifacts as prehensible environmental features optimizing their grip on the world, yet in the course of enacting the improved control routines, the artifacts become frames of reference for establishing and articulating quantitative systems known as mathematical reasoning. 相似文献
