Equity and social exclusion measures in EU lifelong learning policies

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

Predicting transition and adjustment to college: biomedical and behavioral science aspirants’ and minority students’ first year of college

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. This study was made possible by the support of the National Institute of General Medical Sciences, NIH Grant Number 1 RO1 GMO71968-01.

Why some teachers easily learn to use a new virtual learning environment: a technology acceptance perspective

After a decade of virtual learning environments (VLEs) in higher education, many teachers still use only a minimum of its affordances. This study looked at how academic staff interacted with a new and unknown VLE in order to understand how technology acceptance and support materials influence (perceived and actual) task performance. In an experimental design, 36 participants were split into a control (online help) and experimental (instructor video) condition and completed five common teaching tasks in a new VLE. In contrast to most technology acceptance model research, this study found that perceived usefulness of the VLE was not related to (perceived) task performance. Perceived ease of use was related to intentions and actual behaviour in the VLE. Furthermore, no significant difference was found between the two conditions, although the experimental condition led to a (marginal) increase in time to complete the tasks.     

“科尔曼报告”述评——兼论对我国解决“上学难、上学贵”问题的启示

“科尔曼报告”是在二战后随着教育平等、教育民主化思潮的出现以及美国民权法案对教育机会均等现状调查的要求而产生的。报告对美国教育机会均等的现状和影响因素进行了科学的分析,认为校际间差距对不同种族的学生有不同的影响,造成儿童学习水平低的原因,主要不是学校的物质条件,而是学校内的社会因素。“科尔曼报告”深刻地影响了教育机会均等的理论研究与政策实践,对分析和探讨当前我国“上学难、上学贵”问题具有重要的借鉴意义。
