Ethical and political dimensions of action research and lesson study: reflections from a research project on a controversial issue in Cyprus     

Polyxeni Stylianou  Michalinos Zembylas 《Educational Action Research》2019,27(4):581-594

ABSTRACT

As educational interventions that integrate death issues in the school curriculum are rarely designed, implemented and evaluated, our action research (AR) project aimed at investigating the complexities of integrating the concepts of loss and grief in the primary school curriculum of Cyprus. The purpose of this paper is to identify and analyze convergences and divergences between AR and lesson study (LS), as they emerged in our project. We particularly focus on the ways that AR served to legitimate ethically and politically those aspects of the project that constituted the experimentation of lesson plans on loss and grief. The AR and LS elements of our project functioned differently and served different purposes, and we speculate that this is not irrelevant to the controversial aspects of the lesson plans’ topic, namely loss and grief. The paper argues that it may be strategically important, for ethical and political reasons, to both demarcate and associate AR and LS, navigating between them, particularly if a controversial issue is involved.  相似文献   

Deconstructing difference and inclusion in educational research: reflections on the international journal of qualitative studies in education special edition on difference     

M. Nickie Coomer 《International journal of qualitative studies in education》2019,32(3):341-345

Disabled and disability studies scholars and activists have challenged and are challenging the bio- and necro-politics of disability subjectivity through scholarship, art, activism, and online engagement. As this edition articulates, difference takes many forms, is intersectional, and is often characterized and codified by and through educational research. Acknowledging that difference is socially constructed poses challenges to the ablenationalism that undergirds not only complex systems of schooling, but the educational research on which these systems rest.  相似文献   

修身：一个久被忽略的武术研究领域*——来自林语堂“闲适文学”东冷西热现象的启示     

陈〓飞  陈晓丹 《广州体育学院学报》2019,(2):83-87

运用文献资料、历史分析研究方法，以林语堂“闲适文学”之东冷西热现象为借鉴启示，对武术修身在清末民初、民国迄今所遭遇的历史境遇和今天所迎来的时代发展机遇进行论述。旨在呼吁新时期社会条件下，修身将作为武术之一重要价值的彰显，以促进武术未来发展之路更加宽广。主要结论：1）是社会历史发展的现实基础而非林语堂“闲适文学”的优劣，决定了其“东冷西热”现象的发生，及其独特的历史命运和遭际。2）修身在武术研究中地位的历史演绎，经历了清末民初作为提升武术文化层次和社会地位的主要抓手，到民国迄今伴随“科学”彰显对武术修身的理论忌讳及掩蔽这样两个历史节点。3）当今社会语境下修身又迎来了适宜的成长土壤；武术研究者应紧扣时代脉搏，关注修身这一武术理论研究新动向；既是武术之理论研究跟随历史演进步伐，更广层面、更深层次地造福于人类生活，也是武术自身能够在当今社会获得更广阔发展空间的一条重要途径。  相似文献   

A qualitative investigation of design knowledge reuse in project-based mechanical design courses     

Dónal P. Holland  Conor J. Walsh 《European Journal of Engineering Education》2019,44(1-2):137-152

ABSTRACT

The interpretation and reuse of previous design solutions, or precedents, is central to design. This paper describes qualitative research conducted over three years at two institutions, aimed at investigating the role of design knowledge re-use in project-based mechanical design courses. Research data were collected through participant observation, student interviews, anonymous questionnaires, and website analytics. The paper identifies challenges that must be addressed in order to support novice engineers in rehearsing the types of knowledge required to successfully reason about and engage with design precedents. Two categories of design precedents are identified: concept precedents and detail precedents. Providing students with access to the latter is identified as a particular challenge, as is providing students with access to engineering communities of practice. Approaches to addressing these challenges are discussed.  相似文献   

基于用户需求分析的高校图书馆专利服务设计研究——以山东理工大学知识产权信息服务中心为例   总被引：1，自引：0，他引：1  

吴红  李昌  伊惠芳  韩盟  冀方燕 《图书情报工作》2019,63(20):74-81

[目的/意义]高校图书馆的核心价值首先是服务与需求保持高度一致。研究如何扬长避短、契合需求、多元化、多方位实施专利服务，对高校图书馆提高服务绩效、彰显使命担当具有重要意义。[方法/过程]在分析用户需求及服务设计的基础上，以山东理工大学知识产权信息服务中心专利服务实践为例，从普及与提高相结合的专利素质教育、有所为有所不为的专利科研服务、面向产学研政的情报分析与决策支持服务三个维度，探讨高校图书馆的专利服务定位、服务内容以及服务模式。[结果/结论]"高质量满足用户需求"是高校图书馆专利服务工作的着力点。图书馆要有效开展专利服务工作，合理定位是准绳，专业人才是支撑，专利教育是重点，有效机制是保障。  相似文献

Data Visualization as Participatory Research: A Model for Digital Collections to Inspire User-Driven Research     

A. Miller 《Journal of Web Librarianship》2019,13(2):127-155

The emerging creative practices of digital collections are increasing in prominence thanks to the access to, and appeal of, data visualizations. Interactive data visualizations, such as a map, timeline, chart, graph, or artist’s rendering of data, enable users to pursue their own research interests within a collection and participate in new areas of research. Use of these data visualizations enhances the scope of the collection and enables a modern and diverse thematic collection to emerge. This article considers the question: Does the addition of data visualizations affect how users participate with a research collection? Impacts on collection development, application of user-centered design, and analysis of users’ exploratory strategies are discussed. Examples of data visualizations used in digital humanities projects and digital collections are presented as case studies.  相似文献

数据管理能力成熟度模型比较研究与启示     

叶兰 《图书情报工作》2020,64(13):51-57

[目的/意义] 对比分析数据管理能力成熟度模型，为图书馆选择与应用数据管理能力成熟度模型提供参考方案。[方法/过程] 通过模型文本的研究，介绍各模型的结构。采用比较分析法从评价维度（功能域）的设置、模型的组织体系、评价标准与规则、可操作性、公开度等5个方面对7个数据管理能力成熟度模型进行评析。[结果/结论] 每个模型具有其特色功能。CMMI、DMM、DCAM和中国DCMM的评价维度较为全面，中国DCMM即中国-数据中心服务能力成熟度模型具有较强的操作性，且其定量与定性相结合的评价方法值得借鉴。研究数据管理的能力成熟度模型（雪城大学秦健教授团队）和研究数据管理能力成熟度模型（澳大利亚ANDS）考虑图书馆数据管理的实际情况，可作为首选模型。基于各模型的对比与评析结果，形成3种适应不同情境的图书馆选择与应用数据管理能力成熟度模型的方案。  相似文献
