Academic socialization,parental educational expectations,and academic self‐efficacy among Latino adolescents

This study examined the direct association between parental educational expectations and adolescents’ academic self‐efficacy, as well as the moderating influence of parental academic socialization messages. Participants were 148 Latino parent–adolescent dyads with the majority of Mexican origin (80.4%). Most of the parent participants were mothers (85.8%). Adolescents were 13 (46%) or 14 (54%) years of age, and 53% identified as female. Adolescents reported their academic self‐efficacy and perceptions of their parents’ educational expectations; parents reported on their academic socialization messages of shame/pressure and effort regarding academics. The results suggest that, after accounting for parents’ level of education and immigrant status, parental educational expectations were positively associated with adolescent academic self‐efficacy. This association was stronger among adolescents whose parents reported transmitting fewer messages of shame/pressure and academic effort. These results point to the importance of nuances in the content and type of academic socialization messages within Latino families.     

Using Multicultural Resources for Teachers to Combat Racial Prejudice in the Classroom

As the American population continues to become more diverse there is a need to provide children in early education with factual information about all ethnic groups to decrease prejudice. First, teachers must examine their own beliefs prior to implementing a multicultural approach into the curriculum. Three questions are presented that will assist teachers in evaluating their views and behaviors toward ethnic groups. Informative resources are provided for teachers to educate themselves, parents, and students. Through children's literature, instructional materials, and Internet sources, teachers can promote more positive attitudes among students and educate children to be respectful and accept the individuality of others.     

Conditions of domination: reflections on harms generated by the British state education system

Education in Britain increasingly appears to serve a very narrow notion of pedagogy, partly reflecting the ‘conditions of domination’ generated by the rise of the new managerialism in the delivery of public services. In the name of economy, efficiency and effectiveness, social progress is increasingly seen to lie in achieving continual increases in ‘productivity’, realised through giving management the absolute freedom to arrange its resources in whatever way it feels appropriate. At the heart of this critical reflection on these contemporary developments lies a concern for the role of education in democratic development, as well as the various harms that are the direct result of a profoundly reductionist and dehumanising ‘education’ system. The article concludes by outlining some alternative possibilities for more humane and democratic pedagogical processes.

Competencies evaluation in engineering programmes

Results are reported in this paper from a study aimed at evaluating significant competencies in final-year students of some engineering programmes in Chile. The study was carried out by a group of eight universities that were interested in exploring ways to assess learning outcomes such as those demanded by the recent Chilean accreditation system. The authors actively participated in all stages of the study, contributing directly to the design, application and results evaluation of some tests. A sample of 150 students was tested, under conditions that guaranteed the comparability of results. In this paper the authors present results relating to the evaluation of effective communication. The study was backed up by a conceptual model and some hypotheses that are explained and discussed in this work.     

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     

‘Research as dialogue’ and cross-cultural consultations: confronting relations of power

In this paper, we discuss methodological issues that emerged as we worked through a small empirical research project, ‘Engaging Aboriginal students in education through community empowerment’. Recent national policy statements (see, for example, MCEETYA 2000, NBEET 1995) argue the importance of education/research that keeps the locus of control within the Aboriginal community as a means to further the goal of self-determination and improve educational outcomes. In keeping with these recommendations, our project aimed to challenge assimilationist frameworks and sought to ‘empower’ members of the local Aboriginal community through participation in the project.
