Das soziale Rekrutierungsfeld der Lehrer

Fragen der sozialen Selektivit?t im Schulsystem werden gegenw?rtig sehr einseitig, bezogen auf die soziale Herkunft der Lernenden, diskutiert. Die soziale Rekrutierung der Lehrkr?fte und ihre Auswirkungen auf den Umgang mit Schülerinnen und Schülern waren dagegen in jüngster Zeit kaum Gegenstand in der Bildungsforschung. Auf der Basis der ALLBUS-Kumulation 1980–2002 liefert der Beitrag empirisch fundierte Erkenntnisse darüber, wie die Zugangschancen zu akademischen Berufspositionen in Abh?ngigkeit von der sozialen Herkunft variieren. Für den Lehrernachwuchs wird ein soziales Herkunftsprofil nachgewiesen, welches die Lehrerprofession im Gegensatz zu anderen Akademikern st?rker als Beruf des sozialen Aufstiegs kennzeichnet. Die Befunde werfen die Frage auf, ob die sozialen Mobilit?tschancen der Lehramtskarriere die schichtspezifische Selektivit?t im deutschen Schulsystem nicht sogar im Sinne eines kumulativen Effektes verst?rken.     

School-level environment and outcomes-based education in South Africa

In this study, we developed and validated a questionnaire to assess teachers’ perceptions of their actual and preferred school-level environment, investigated whether teachers involved with Outcomes-Based Education (OBE) perceive the school-level environment differently from those who are not, and investigated factors in the school-level environment (such as resources and staff freedom) linked with a school’s likelihood of successfully implementing OBE. The study involved modifying and validating an existing questionnaire to make it suitable for assessing the school-level environment in South Africa, as well as adding to the School-Level Environment Survey (SLEQ) the scales of Familiarity with OBE and Parental Involvement. Analysis of data collected from 403 teachers provides evidence for the validity and reliability of the new SLEQ-SA. MANOVA for repeated measures revealed a statistically significant (p < 0.01) difference between teacher perceptions of their actual school environment and the one that they would prefer for all seven SLEQ-SA dimensions. When MANOVA was used to examine whether teachers involved in OBE perceive their school-level environments differently from those who are not, statistically significant differences emerged for two of the seven school-level environment scales, with teachers involved with OBE perceiving significantly more Familiarity with OBE and Work Pressure. The constraints faced by teachers are wide ranging and include a number of factors such as a lack of material resources and large class sizes. The results provide valuable information to policy-makers, principals and researchers that potentially could help to guide the implementation of OBE.     

‘Now I am free’—education and human resource development in Eritrea: contradictions in the lives of Eritrean women in higher education

Human resource development as an objective of education policy in developing countries is increasingly narrowed down to its human capital component. In Eritrea, the objective of a highly centralized human resource development strategy is to produce human capital for the advancement of the nation. This instrumentalist view ignores the fact that education is not only related to one's position in a given society, but equally to the development of personal identity and new forms of agency on an individual level—thus potentially encompassing contradictions between the individual and the common good. This paper—based on the personal histories of a sample of female students at Asmara University—discusses these contradictions in terms of these women's acceptance of and resistance to the government's plan for them. It further argues that an education system geared predominantly towards the creation of human capital is bound to do so at the expense of social solidarity.     

Brown and black in white: The social adjustment and academic performance of Chicano and black students in a predominately white university

This article explores the academic and social experiences of Chicago and black students at UCLA. The analysis proceeds by examining differences in social backgrounds, high school and college experiences, and explores the relationship between these factors and college adjustment and achievement (GPA). Drawing upon recent theory on class reproduction and schooling we show particular concern with the role of social class in explaining differential outcomes. The findings indicate that blacks are more likely than Chicanos to feel alienated and perform poorly, and that social class makes no difference in these outcomes for blacks. However, middle class Chicanos perform better and are better adjusted than working class Chicanos. We discuss our findings in the light of theories of class reproduction, cultural capital, and racial signaling, suggesting that theories of reproduction must acknowledge the role of race in unequal school outcomes.     

Performance measure for image fusion considering region information

An objective performance measure for image fusion considering region information is proposed. The measure not only reflects how much the pixel level information that fused image takes from the source image, but also considers the region information between source images and fused image. The measure is meaningful and explicit. Several simulations were conducted to show that it accords well with the subjective evaluations.     

Quality management in Hungarian higher education: organisational responses to governmental policy

This article focuses on responses of higher education institutions to governmental policy. We investigate the influence of organisational characteristics on the implementation of quality management in Hungarian higher education institutions. Our theoretical framework is based on organisational theories (resource dependency and neo-institutionalism), Allison’s models on organisational decision-making processes, and also addresses some of the more specific characteristics of higher education institutions. Our empirical investigation shows that organisational characteristics matter in policy implementation of quality management in Hungarian higher education. Certain organisational variables, viz. leaders’ commitment to the implementation process, the involvement of external consultants, institutional reputation, and bureaucratic and political decision-making processes have strong effects on the implementation of quality management. Characteristics particular to higher education institutions were much less influential.

Perceptions of pedagogical formation students about Web 2.0 tools and educational practices

This study aims to examine pedagogical formation students’ perceptions about Web 2.0 tools and educational practices. A case study approach forms the methodological framework of this study. This study was conducted with 42 pedagogical formation students of an Instructional Technology and Material Design course during the 2014–2015 spring semester. During the course, the students created digital materials such as puzzles, concept maps, worksheets, presentations and posters by using software including Prezi, Glogster, and Webspiration. Furthermore they were introduced to numerous Web 2.0 tools which were required learning for the purpose of the course. The data for this study was collected by the researcher through a questionnaire and open-ended questions developed in order to identify students’ views on Web 2.0 tools and educational practices they will face in their future professional life. Content analysis, frequency and percentage were used in the analysis of data. Answers to the following were sought from the data analysis: (1) which Web 2.0 tools do students use or planned to use in their current and future professional life (teaching profession); (2) what are the reasons students want to use Web 2.0 tools in their professional life as a teacher; (3) what are the views of students about their use of Web 2.0 tools in the educational context; and (4) what are students’ views about Web 3.0 technologies and the changes and innovations that will be brought about by these technologies in the field of education.     

Family Meal Participation as a Corollary of Positive Youth Development: Opportunities for Counseling Services

Research reveals multiple academic, behavioral, and psychosocial benefits of participating in family meals. The studies also reveal an inverse relationship between family meals and high-risk behaviors among youth. Family meal participation provides opportunities for Positive Youth Development (PYD) an emergent prevention science framework that emphasizes strengths and contextual resources rather than deficits of youth. This article reviews and integrates data that demonstrate the precise ways in which family mealtime positively impacts youth developmental trajectories. It is also maintained that counseling professionals are well-positioned to implement public education prevention measures and to facilitate changes in policy and social norms that encourage regular family meal participation and advance PYD.
