In a scientific dispute over the effects of atrazine on amphibians, chemical industry–funded and publically funded scientists present stunningly contrasting constructions of atrazine's environmental concentrations, persistence, and potential to harm. Considerable scientific uncertainties and variable ranges allow authors to construct preferred versions of the story of atrazine. These incommensurate rhetorical constructions, more the result of competing economic and environmental interests than of any paradigmatic misalignments, have prolonged the dispute not only over atrazine's effects but also over whether its sales should be banned.  相似文献

Written nearly 40 years ago, Peter Medway’s Finding a Language continues to be an arresting read, which offers a powerful vision of what might be possible in education. In this brief introduction, I set the work in context, referring to ideas that Pete engaged with and recalling a little of the times.  相似文献

Despite over three decades of legislation and initiatives designed to tackle the traditional gender divide in the science, technology and design fields, only a quarter of the registered architects in Australia are women. There are no statistics available for other design disciplines, with little known about why women choose design as a career path and who or what influences this decision. This qualitative research addresses this knowledge gap, through semi‐structured in‐depth interviews conducted with 19 Australian women who completed an industrial (product) design degree. Thematic analysis revealed three key themes: childhood aptitude and exposure; significant experiences and people; and design as a serendipitous choice. The findings emphasise the importance of early exposure to design as a potential career choice, highlighting the critical role played by parents, teachers, professionals and social networks.  相似文献

"协同教育"是协同学理论在教育领域应用而形成的新的教育理论。"双‘三维一体’"协同教育是在整合"三维一体"协同教育优点,总结"三维一体"协同教育在实践过程中出现的不足和缺陷而形成的新的理论。"双‘三维一体’"协同教育强调纵向"三维一体"——学校、家庭、社会各系统教育力量的互相结合、协调统一,同时强调横向"三维一体"——哲学、科学、实践的结合、协调、同步,同时还强调纵向与横向"三维一体"的彼此融合、协调、协同发展。  相似文献

Teachers' perception of changes to their teaching practice, with respect to digital technology use in secondary school mathematics, during their participation in a research project are reported. Two case studies are presented of teacher perspectives illustrative of the range of perceived changes teachers made to their practice and positions along the ‘path of change’ during their participation in the project. Participating in a project supportive of teacher change and resulting in perception of substantial change was necessary, but not sufficient, to meet the goal of transformative use of digital technologies to increase the level of cognitive demand experienced by students.  相似文献

This article reports on a two-year evaluation of the Gauteng Primary Language and Mathematics Strategy (GPLMS), an innovative system-wide reform intervention designed to improve learning outcomes in Gauteng Province, South Africa. Using data from universal testing of all learners in 2008 on a provincial systemic evaluation, as well as data from the 2011, 2012 and 2013 Annual National Assessment tests, this article investigates whether or not the GPLMS improves the numeracy skills of learners in early-grade mathematics in underperforming schools. Using as identification strategy, the natural experiment that resulted from a miscalculation of the provincial systemic evaluation test scores in 2008, which had been used to assign schools to the GPLMS intervention, the study shows that the GPLMS intervention is positively associated with improvements in early-grade mathematics performance of schools in the neighbourhood around the assignment threshold. The findings of the study contribute to the growing body of knowledge that shows the effectiveness of combining lesson plans, learner resources, and quality teacher capacity building.  相似文献

Parallel Support (PS) is a co-teaching program designed to deliver education services in inclusive settings in Greece. In this quantitative study, 236 special education PS teachers from six major educational regions participated in a survey. The findings indicate that PS is similar to the One Teach, One Assist approach, constituting a static model, which typically provides services to one or two students with disabilities. Deeper cultural characteristics of the Greek educational system may shape the PS's peculiarities. In our transcultural hypothesis, the PS model is a compromise between a highly demanding collaborative approach and a pre-existing low collaboration school culture.  相似文献

This study investigates the factors determining children's educational attainment, focusing on gender-differential intergenerational patterns, by employing a case study from rural Mindanao. The result mainly shows, unlike general trends in developing countries, educational attainment is more favorable for girls; maternal education level is equally associated with daughters’ and sons’ education levels, and paternal education level is preferentially favorable to their sons. To reduce the disparity, suggestions include providing boy-specific interventions to enhance the magnitude of the father–son educational virtuous circle and comparing the magnitude of gender-equal maternal and boy-preferential paternal education influences to specify which effect is larger.  相似文献

Despite recent evidence that students in public schools significantly outperform their private school counterparts, private schooling continues to account for approximately 40% of secondary school enrolments in Indonesia. In an effort to explain this sustained demand, we combine analyses of PISA data with in-country interviews and school visits. Ultimately, we find that although government dependent private schools are underfunded with a high proportion of uncertified, underpaid teachers (with limited access to training and professional development), demand remains high due to their focus on religious training and education, as well as their ability to increase educational access for low-income families.  相似文献
