In June 1979, the Swedish Government appointed a Commission of Inquiry to look into the total training requirements for Swedish personnel in contact with the developing countries. This action was taken against a background of increased Swedish involvement in the development countries, in aid, industry and a large number of voluntary organisations, and in the light of the demands made on Swedes serving in developing countries due to living and working in an alien environment.

The Commission commenced its work in September 1979* and worked closely with a reference group consisting of representatives drawn from the Swedish administration, the business world, the missionary societies and the trade union movement. This article summarises those parts of the Commission's report which are relevant to the theme of this issue.  相似文献

In recent years, the usages of by-products and wastes in industry have become more important. The importance of the sustainable development is also of increasing. The utilizations of wastes, as mineral admixture or fine aggregate, reduce the consumption of the natural resources and improve the durability of concrete. In this study, the effect of the fineness on the high temperature and sulphate resistances of concrete mortar specimens, produced with ground granulated blast-furnace slag (GBFS) replacing cement, is investigated. The compressive and flexural strength test results for all series related to durability effects, exposing temperature and solutions, exposure times for these durability effects, slag content and fineness are discussed. Conse- quently, the optimum slag contents are determined for producing the sulphate and high temperature resistant mortars.  相似文献

Background: Numerous studies have been conducted to investigate the factors related to science achievement. In these studies, the classroom goal structure perceptions, engagement, and self-efficacy of the students have emerged as important factors to be examined in relation to students’ science achievement.

Purpose: This study examines the relationships between classroom goal structure perception variables (motivating tasks, autonomy support, and mastery evaluation), engagement (behavioral, emotional, cognitive, and agentic engagement), self-efficacy, and science achievement.

Sample: The study participants included 744 seventh-grade students from 9 public schools in two districts of Gaziantep in Turkey.

Design and methods: Data were collected through the administration of four instruments: Survey of Classroom Goals Structures, Engagement Questionnaire, Motivated Strategies for Learning Questionnaire, and Science Achievement Test. The obtained data were subjected to path analysis to test the proposed model.

Results: Students’ perceptions of classroom goal structures (i.e. motivating tasks, autonomy support, and mastery evaluation) were found to be significant predictors of their self-efficacy. Autonomy support was observed to be positively linked to all aspects of engagement, while motivating tasks were found to be related only to cognitive engagement. In addition, mastery evaluation was shown to be positively linked to engagement variables, except for cognitive engagement, and self-efficacy and engagement (i.e. behavioral, emotional, and cognitive engagement) were observed to be significant predictors of science achievement. Finally, results revealed reciprocal relations among engagement variables, except for agentic engagement.

Conclusions: Students who perceive mastery goal structures tend to show higher levels of engagement and self-efficacy in science classes. The study found that students who have high self-efficacy and who are behaviorally, emotionally, and cognitively engaged are more successful in science classes. Accordingly, it is recommended that science teachers utilize inquiry-based and hands-on science activities in science classes and focus on the personal improvement of the students. Furthermore, it is also recommended that they provide students with opportunities to make their own choices and decisions and to control their own actions in science classes.  相似文献

Teachers across all subject areas engage students, in some way, in the study of otherness—other societies, other cultures, other practices. Often teachers and teacher educators attend to teaching about others with strong desires toward social justice as they seek to make a difference and do good. However, with insufficient tools to interrogate their practices and beliefs to think critically what good actually entails, they can unwittingly pave the road to hell. When good intentions are additionally coupled with the bad science of incomplete knowledge, misinformation, and weak arguments, the road can get treacherous. In this article, we examine the road to hell as it winds through teaching about a specific other, Muslims. We examine how good intentions and bad science about Muslims and Islam have worked to cement stereotypes, promote intolerance, shut down learning, and in doing so thwart education for social justice. Peering closely, we examine commonly voiced student conceptions of Muslims/Islam/The East and highlight the good intentions and bad science behind many of the popular discourses that students advance. We then offer strategies for building a different path, by problematizing good intentions and repairing bad science.  相似文献

Youth-movements in Israel are non-formal organizations that educate for social and political involvement and provide a broad platform for youth involvement in the community. This study explored the question: does the social activism of adolescents who both elect for membership in youth movements and a leadership role of instructing younger members also reflect itself in environmentalism? In a survey of 1496 young instructors drawn from 15 official youth movements, findings on environmental literacy variables show youth are only generally knowledgeable about environmental problems; express ‘technical-optimism’ which leads them to limited concern for the environment; show limited recognition of the importance of environmental education, and show limited acknowledgment of the necessity for changes in personal consumerism. Findings also show that environmental issues are not on their mind since they are not a conversation topic with peers or family. Nonetheless, these youth also demonstrate strong self-efficacy to effect change; view themselves as role models for younger members; and express willingness to include environmentally-supportive activities within regular youth movement activities. Their valuing of nature also provides a foundation for building other environmental values. Further analysis shows how these findings can contribute theoretical and practical tools for incorporating sustainability within the youth movement framework, and help realize their potential for promoting sustainability in society.  相似文献

The authors mainly aimed to investigate the following question: Are there any significant effects of the first combined method of a conceptual change approach with refutation text, worksheets, and activities with respect to the second combined method of a conceptual change approach with conceptual texts, presentations, and activities on students' misconceptions and achievement on a 3-tier posttest score measuring Grade 7 basic astronomy concepts when independent variables are controlled? There was a statistically significant effect of the first combined method with respect to the second method at the medium effect size on both misconception scores and achievement scores. This finding clearly demonstrates that use of the first combined method, which included refutation texts with worksheets, eliminated the students' misconceptions and increased their achievement. The second combined method also increased the students' achievement, but almost 40% of their misconceptions remained.  相似文献

During the Ottoman period, ‘science (ilim, pl. ulûm)’, ‘knowledge (marifet, pl. maarif)’ and ‘technique (fen, pl. fünûn)’ emerged as three important concepts of knowledge. Maarif, which came into prominence with Selim III, began to undergo a semantic transformation together with the concepts of ulûm and fünûn and by the time of Mahmud II it had become an overarching concept representing the knowledge dimension of the new era. This article discusses the semantic transformation of maarif, focusing on the period between 1789 and 1839. This study applies the history of concepts approach developed by Reinhart Koselleck, whereby a synchronic analysis of the concept of maarif is undertaken alongside an examination of its diachronic dimension. This reveals an ambiguous and multi-dimensional structure and helps us to account for its evolution as an umbrella term.  相似文献
