ABSTRACTModels relating to the participation of children are often explicitly aimed at facilitating or evaluating participation in decision-making processes on local levels. However, these models often build on hierarchically ordered ‘ladders’ of children’s involvement starting with passive involvement and increasing gradually to highly active engagement. Such models become problematic when designing or evaluating participative activities for young children. On the basis of two ethnographic studies conducted in children’s libraries, we propose an alternative model based on a view of participation as processual rather than definitive. Theoretically, the paper draws mainly on human rights theory as well as on theories and concepts derived from childhood studies such as participation and citizenship. The new model of participation demonstrates how the idea of participation can be operationalized at practical levels to include the very youngest children. 相似文献

ABSTRACTThe reality of anthropogenic climate change has been established ‘beyond reasonable doubt’ by leading scientists worldwide. Applying a systematic literature review process, we analysed existing literature from 1993 to 2014 regarding climate change education for children and young people, with the aim of identifying key areas for further research. While a number of studies have indicated that young people’s understandings of climate change are generally limited, erroneous and highly influenced by mass media, other studies suggest that didactic approaches to climate change education have been largely ineffectual in affecting students’ attitudes and behaviour. The review identifies the need for participatory, interdisciplinary, creative, and affect-driven approaches to climate change education, which to date have been largely missing from the literature. In conclusion, we call for the development of new forms of climate change education that directly involve young people in responding to the scientific, social, ethical, and political complexities of climate change. 相似文献

陕西境内遗址出土后短时间内表面产生白色物质CaSO42H2O是非常普遍的现象。本研究利用土柱模拟遗址出土后表面产生CaSO42H2O的过程,通过监测土柱中土壤的湿度、含盐量及离子变化综合分析CaSO42H2O产生的原因,研究结果表明遗址出土后形成了新的界面层,在蒸发的作用下,地下水沿土壤孔隙向上迁移,同时将可溶盐带入土壤中,表面的可溶盐含量逐渐增大,达到峰值后不再增加,实验后测得表面土壤中的Ca2+和SO2-4是原始土壤的数十倍,说明遗址表面产生CaSO42H2O是水盐运移的结果。本研究可为遗址出土后预防CaSO42H2O的产生提供依据。 相似文献
