Retraining chemistry teachers in the Philippines     

Mr Rex Kerrison 《Research in Science Education》1992,22(1):248-254

A recent large scale educational aid program to the Philippines included the retraining of secondary chemistry teachers. Teachers were introduced to new content and to alternative teaching strategies. An initial resistance to change arose as it was perceived that the new approaches did not take into account very limited school facilities and very large teaching groups. The lecturing style of teaching, which predominates at all levels throughout the country, was seen as the most effective method to handle overwhelming classroom problems. Resistance was overcome after alternative teaching styles were modelled. This paper gives an overview of the aid program and outlines the introduced teaching strategies. It contends that Asian teachers have been largely unaffected by western educational aid due in part to the fact that such aid is rarely accompanied by the modelling of introduced strategies. Specialisations: primary teacher education, primary mathematics, pre- and in-service science education.  相似文献   

Addressing the messiness of data analysis: Praxis,readiness and tips from doctoral research     

Nozomi Sakata  Carly Christensen  Hannah Ware  Sihui Wang 《Compare》2019,49(2):318-336

Despite the fluid and nonlinear nature of data analysis, specifically in qualitative research, published work in comparative education has rarely discussed the messy aspects of data analysis. This Forum addresses the complexity of the analysis stage faced by three doctoral researchers in terms of: considering data analysis when selecting data collection tools; messiness of data analysis deriving from fieldwork and data collection; integrating different data sources; practising reflexivity during data analysis; and ethical issues arising from data analysis. The Forum aims not only to offer suggestions and tips to deal with data analysis but also to encourage more open discussions on this topic within the research community.  相似文献   

Transgenics in agriculture     

D. Rex Arunraj  B. Gajendra Babu 《Resonance》2001,6(2):83-92

Biotechnology has opened unprecedented avenues for exploring biological systems. One of the key techniques in genetic engineering is gene transfer, which involves transfer of recombinant DNA into plant cells to generate transgenic plants. Genes and genomes from a wide range of organisms are being manipulated for the benefit of mankind. Application of genetic engineering in agriculture has produced significant achievements such as yield improvement of major food crops.  相似文献

Promoting Social and Emotional Learning in Second Grade Students: A Study of the Strong Start Curriculum     

Paul Caldarella  Lynnette Christensen  Thomas J. Kramer  Kalli Kronmiller 《Early Childhood Education Journal》2009,37(1):51-56

The promotion of social and emotional learning (SEL) in schools may help prevent emotional and behavioral problems of students. This study evaluated the effects of a SEL curriculum, Strong Start, on the social-emotional competence of 26 second grade students, using a quasi-experimental, non-equivalent control group design. Results revealed statistically significant and meaningful improvements in teacher ratings of students’ internalizing and peer-related pro-social behaviors, particularly for students at greater risk. Conversely, control group students experienced significant worsening of internalizing behaviors and decreased levels of peer-related pro-social behaviors. No changes were reported in externalizing behaviors for either group. Treatment integrity and social validity ratings of Strong Start were high. Limitations and implications of this study are addressed. The authors are listed alphabetically by last name and all shared equally in the preparation of this paper.  相似文献   

Aid effectiveness in education: Why it matters     

Desmond Bermingham  Olav Rex Christensen  Timo Casjen Mahn 《Prospects》2009,39(2):129-145

This article introduces the special issue of Prospects on “Aid effectiveness in education”. It brings together case studies of attempts in several very different contexts to improve the effectiveness of the use of aid in the education sector. By drawing on the historical evolution of the new paradigm over the last 20 years, the authors make the case for a closer focus on aid’s effectiveness in education, as well as the need to reform the aid effectiveness architecture. In particular, they identify two major obstacles that need to be overcome to improve aid’s effectiveness in education: the lack of sufficient institutional and staff incentives for coordinated and harmonized behaviour; and factors that lead to risk-aversion and discourage innovation in delivering aid effectively.  相似文献

Trolling in online communities: A practice-based theoretical perspective     

Angela Gracia B. Cruz  Mathew Rex 《The Information Society》2018,34(1):15-26

The literature on trolling has viewed trolling as discrete instances of transgression undertaken by antagonistic individuals. We identify three main issues with current theorizations: diffuse definitions of “trolling,” blurred boundaries between trolling and other online anti-social behaviors, and the context dependency of trolling. To address these unresolved issues, we adopt a practice-based theoretical approach. Informed by this approach, we analyze trolling behaviors not as products of individuals' attitudes, values, and decisions, but rather as behaviors embedded within and occurring as part of social practices. Specifically, we conduct a practice-based theoretical analysis in a multi-site exploratory study involving online archival research and in-depth interviews with online community members. Based on this analysis, we propose that trolling be conceived as a constellation of three social practices: learning, assimilating, and transgressing. Also, we find that practices of trolling transgression can have a dual pro-social and anti-social impact in online communities.  相似文献
