This article addresses the question of how science learning can be improved. It recognizes that, while learners themselves are responsible for their own learning, the quality of this learning is greatly influenced when appropriate resources are available to learners. These resources are provided through a partnership between teachers and learners. Three different types of resource are discussed. Tools, in the form of computer tools and conceptual tools, make tasks easier and allow learners to undertake tasks they would not otherwise be able to do. Tasks can facilitate effective learning by creating effective spaces for learners to work in, embodying key aspects of the disciplines of science, providing effective and authentic opportunities for learners to learn, and facilitating a dialogue between learners ideas and their experiences of the natural world. Environment – the ecology in which learning happens – provides three sources of information through the human, social, and conceptual worlds. When key aspects of these worlds are manifested in the environment, they scaffold the learning of science content, the nature of science, and the learning process itself, all of which are required for the deep understanding of science that constitutes improved science learning.  相似文献

探讨"绿色"室内设计的设计原则   总被引:3,自引:0,他引:3  
“绿色”室内设计概念的提出是室内设计发展的必然趋势。“绿色”室内设计就是要求设计师在对室内环境的建造过程和使用过程以及销毁过程中合理有效地利用自然资源和能源,对自然环境施加最小影响,甚至能产生积极的作用,保护环境,创造亲切舒适、健康安全、“以人为本”的室内环境。  相似文献

We investigated whether perceived inclusion and exclusion with peers at school, as well as self-reported bullying exposure, affected positive and negative affect among 1161 students from grades five through seven. Positive affect was significantly, but only weakly, affected by perceived exclusion and inclusion. Negative affect was not related to perceived inclusion; however, both perceived exclusion and self-reported bullying exposure gave effects on negative affect. Our research points to the need of creating a learning environment that promotes inclusion and caring and supportive interpersonal relationships. This will probably increase student functioning.  相似文献

In Australia, emphasis in early childhood education policy is placed on the importance of the role of the family as a child's first educator, and finding effective ways to raise the effectiveness of parents in supporting children's learning, development and well-being. International studies demonstrate that the home learning environment (HLE) provided by parents is closely associated with children's cognitive outcomes: literacy activities at home are likely to predict children's literacy abilities and numeracy activities at home are likely to predict children's numeracy abilities. However, studies focusing on building the capacity of primary caregivers to increase informal learning opportunities, such as enhancing children's literacy and numeracy learning in the HLE, have rarely been the focus of research. This study uses a sample of 113 four-year-old children to explore the association of specific aspects of the HLE with different child outcomes while controlling for child and family characteristics. In addition, a non-intensive, yet purposeful and systematic intervention to draw parents’ attention to the principles of dialogic reading and the principles of counting was introduced. Study findings suggest that parents responded positively to this approach, and that literacy and numeracy aspects of the HLE were specific predictors for children's numeracy and literacy competencies.  相似文献
