Abstract The focus of this article is a comparative review of the science curriculum for England and Wales from the perspective of recent developments in the United States of America, Australia, New Zealand and the Canadian province of Ontario. In the comparison of science curriculum documents and the language deployed, questions are raised about differences as well as commonalities among and between documents from various jurisdictions. Issues discussed include: the varying emphases upon science topics and/or intended learning outcomes; integration with other curriculum areas; the content and organization of the science curriculum; and ways of assessing students’ performances and understandings. The article draws attention to the importance of comparative analysis which informs our understanding of the effects of curriculum change, its relation to students’ achievements in science, and the need to support the development of teachers. 相似文献

In the digital era, information literacy skills enable users to locate and use online materials effectively. One persistent library service for libraries is providing skills training to students. This article traces the creation of online library instructional tutorials, currently referred to as digital learning objects, in academic libraries. It isolates the factors that improve the success of these learning tools, including knowledge of the tutorials’ purpose and potential, collaboration with other individuals, the use of standards, student engagement, and evaluation. The literature review also illustrates the incorporation of multimedia learning theories and assessment strategies in these tutorials. By developing appropriate learning tools, librarians offer services aimed at meeting user needs while reducing time and resource demands on library staff. 相似文献

为厘清国内外近十年(2011-2021年) 羽毛球教学领域研究的最新进展,该研究采用系统性文献综述法,选取Web of Science、EBSCO、Elsevier、中国知网等数据库中的27篇高质量实证研究论文,从研究主题、研究情境、研究方法、研究因变量四个方面进行统计分析,得出以下结论:(1)从研究主题上看,羽毛球教学领域的研究主题主要集中在教学法与教学设计、信息化技术与教学融合和羽毛球训练3个方面,其中又以教学法与教学设计的研究最多;(2)从研究情境上看,羽毛球教学领域研究主要面对大学生开展小样本、短周期的研究;(3)从研究方法上看,羽毛球教学实证研究仍集中于收集定量数据,针对定性数据的收集方法较少,且定性数据的收集方法使用频率也较低;(4)从研究因变量上看,国内外羽毛球教学的实证研究大都关注学习者的运动能力,而关注健康行为的研究偏少,且几乎没有研究将体育品德作为研究因变量。可见,目前羽毛球教学领域研究存在研究主题不够全面和深入、研究方法综合运用欠缺、研究情景较为单一、研究因变量存在空缺等问题。最后,探讨了该研究对羽毛球教学实践和科学研究带来的启示,以期促进我国羽毛球教学的发展。 相似文献

An animated concept map is a presentation of a network diagram in which nodes and links are sequentially added or modified. An experiment compared learning from animated concept maps and text by randomly assigning 133 undergraduates to study 1 of 4 narrated animations presenting semantically equivalent information accompanied by identical audio narration. Two of the animations presented text; one with concurrent audio and another with delayed audio. Two of the animations presented concept maps; one in black and white and the other with nodes colored to represent semantic relatedness. The concept map groups outperformed the text groups on free recall (p < .05). The black-and-white concept map group outperformed the text groups on a multiple-choice knowledge test (p < .05). No advantages were statistically detected for color enhancements of the animated map. The results indicate that verbal information can be effectively communicated by learner-paced animated concept maps accompanied by audio narrations. 相似文献

Reflection and reflective practice are key concepts in the educational literature as well as in research on physical education (PE) and physical education teacher education (PETE). The purpose of this article is to review the current empirical knowledge base for reflection and reflective practice in PE and PETE from 1995 to 2011. The review includes empirical research published in peer reviewed journals on the topics on reflection and reflective practice in the contexts of PE and PETE. There were 33 articles included in the review. Most of the research is conducted in the PETE context, where it was found that pre-service teachers do develop their reflective capabilities. However, the results also indicate students make little progress on critical reflections. In the PE context, it was found that teachers express a need for reflective communities. Theoretical and methodological challenges with the reviewed literature are discussed and suggestions for further research proposed. 相似文献
