Improving nature of science instruction in elementary classes with modified science trade books and educative curriculum materials     

Jeanne L. Brunner  Fouad Abd-El-Khalick 《科学教学研究杂志》2020,57(2):154-183

This study investigated the effect of including explicit nature of science (NOS) content in read-alouds of elementary science trade books on the teaching and learning of NOS. We focused on three aspects of NOS: the creative, the empirical, and the inferential NOS. The trade books were read aloud by teachers in three hierarchical levels: Level I served as a control and consisted of a trade book that remained unmodified, Level II consisted of a trade book that had been modified to include explicit references to NOS, and Level III consisted of a modified trade book accompanied by educative curriculum materials that were aimed at improving the teachers' views of NOS as well as supporting teaching about NOS. We used the Views of Nature of Science Questionnaire-form CE (VNOS-CE) preintervention and postintervention to determine changes in teachers' views of NOS and interviews preintervention and postintervention to determine changes in students' views. Audio recordings of read-alouds were used to determine changes in teaching practice, including the frequency and the quality (i.e., naïve or informed) of the NOS references in the discussions. Interviews were used to determine teachers' perceptions of the modified trade books and educative curriculum materials. We found that both teachers and students developed more informed views of the targeted NOS aspects after the intervention and that teachers addressed NOS more often, and in a more informed manner, when they had trade books that explicitly supported NOS instruction and educative curriculum materials that supported their learning about NOS. Furthermore, they perceived the intervention materials favorably. Teachers' views and practices were able to change in tandem because of the intervention materials that supported explicit NOS instruction. We highlight the need for more widespread development of similar educative curriculum materials.  相似文献   

Decoding digital transformational outsourcing: The role of service providers’ capabilities     

《International Journal of Information Management》2021

The business process outsourcing industry has got disrupted, first by the significant shift in value creation activities from the clients to the service providers, and second by pervasive digital penetration, resulting in the emergence of Digital Transformational Outsourcing (DTO). Service providers now play a more significant role, making their capabilities important. In the new context, service providers require a uniquely different set of dynamic capabilities to handle end-to-end business functions on behalf of their clients while delivering digital value propositions.We study 26 of the largest global business process outsourcing providers to conceptualise and identify six dynamic capabilities of service providers salient in the new context, i.e., consultative, orchestration, insights, network management, knowledge access, and standardisation. Interviews conducted with industry experts provided evidence in support of the identified dynamic capabilities. A novel firm capability dataset was created using secondary data, and using fuzzy-set Qualitative Comparative Analysis (fsQCA), we identify configurations for high and low performance and find them to vary by the firm's broad/narrow scope.  相似文献   

图书馆珍贵资料的开放数据化建设——以京都府图书馆藏明治时期以来旅游指南的数字化项目为例     

福岛幸宏  原田隆史  李颖 《图书馆杂志》2020,(4):113-118

近年来,日本有越来越多的图书馆开始尝试将馆藏珍贵文献资源进行数字化并在网上公开服务。但从数字人文学角度而言,这些资源存在着"使用范围与规范不明确""公开的数据格式不统一""数字资源的搜索手段不完善"等种种问题,因而可能无法为读者提供有效的服务。"京都府立图书馆珍贵文献收藏"项目是将京都府立图书馆馆藏珍贵文献进行数字化并在网上公开服务,于2019年3月推出第一期,内容为明治时期到战后期(第二次世界大战结束后联合国军占领时期)面向外国游客、以京都为主的城市观光指南。该项目采用了CC0协议(创作共用协议零权利协议)使用许可、DOI机制(数字对象唯一标识符)、IIIF(国际化图像互操作框架),均为世界标准,开创了日本图书馆领域的先河,今后将向全国推广。此次报告我将介绍本系统研发的过程、系统构建的细节。我们还询问了市民与人文学专家的实际使用感受、系统的使用效果与改善意见,也将一并向各位介绍。  相似文献   

‘Borrowed access’ – the struggle of older persons for digital participation     

Linda Reneland-Forsman 《International Journal of Lifelong Education》2018,37(3):333-344

This study investigates older persons engagement with digital interfaces as one important way to social inclusion. Digital exclusion and social exclusion are intrinsically intertwined, which put older persons at risk for exclusion. To construct meaningful educational practices for inclusion, more insight is needed to understand consequences of low digital competence. Eighteen men and women (retired) have been interviewed about their everyday encounters with digital interfaces. Results show how older persons ‘borrow’ knowledge from social networks or from contacts at previous workplace, to access technology and digital practices. Data also show a common acceptance of exclusion and changes in lifestyle. These fragile chains, put together to access digital practices jeopardise social inclusion understood as autonomy and participation in society. Informants did not mention community arrangements as resources for access and knowledge, which indicate that hard work is required to promote inclusion of this group. A possible way could be using the power of informally framed learning scenarios. Society cannot turn a blind eye to the fact that groups of citizens are hindered from developing capabilities to maintain a social life, to access the health sector, to enjoy integrity and independence and cultural recreation – to live a capable life.  相似文献   

The role of a digital engineering platform in appropriating the creation of new work-related mind-set and organisational discourse in a large multi-national company     

《International Journal of Information Management》2019

This paper reports on a case study involving a strategic and innovative approach to creation of an in-house multifaceted digital engineering platform (the DEP) in overcoming a number of organisational problems at a multinational engineering company. The DEP was to be used strategically for simplifying the operational complexity and to create and appropriate new work-related mind-set and new organisational discourse to achieve homogenous working across the organisation, which is a huge challenge. The need for this system emerged from the need to resolve many organisational services related problems that carried phenomenal amount of processes, health and safety risks and to regulate, and, control the running of engineering project. Research data were collected using a longitudinal case study approach over a period of six months. In order to make sense of how the DEP helped the organisation, the study used certain elements of Extended Structuration Theory as a lens to assess the case study. This research discovered that the DEP succeeded in creating and appropriating work-related mind-set and organisational discourse. It also had real influence on working processes and employees at all levels while encouraging transparency, responsiveness, agility and accountability. It continues to help the organisation to govern, manage and maintain good standard of service but many barriers still remain.  相似文献

Digital government transformation: A structural equation modelling analysis of driving and impeding factors     

《International Journal of Information Management》2021

Digital technologies are transforming the public sector by affecting applications, processes, culture, structure, and civil servants’ responsibilities and tasks. Yet, there is a void in research about driving and impeding factors influencing digital government transformation (DGT). The article contributes to the current debate on DGT by quantitatively assessing the transformation and its driving and impeding factors. The analyses were performed by collecting and analyzing through structural equation modeling 491 answers to a survey to Italian administrations. Results show that DGT is influenced by a combination of different factors, including the sense of urgency, the need for change, and the creation of a collaborative environment, suggesting that more effort is required for including public managers in the current debate on DGT. Organizational barriers and lack of support are impeding factors. Finally and counter-intuitively, resistance to change was not found to impede the transformation.  相似文献   

马克思主义人的本质观思想视域下的高校思想政治教育     

杨铭 《重庆职业技术学院学报》2011,20(1):104-106

高校思想政治教育是以人为本位的教育活动。研究人的本质问题,是有效开展思想政治教育的理论前提。马克思主要从人的类本质与人的社会本质两方面入手,对人的本质问题进行了科学阐述,其理论着力点与当前高校思想政治教育工作要求相契合。高校应与时俱进地不断总结完善马克思主义人的本质观,并将其基本理论贯穿于整个高校思想政治教育工作中。  相似文献   

刘基《春秋明经》若干问题探究     

郑任钊 《浙江工贸职业技术学院学报》2011,11(3)

刘基《春秋明经》是为举业而作,有因循《春秋胡氏传》的思想内容,也有超越《胡传》的思想内容,研究《春秋明经》的思想需要与《胡传》进行对比甄别。《春秋明经》在夷夏问题上,坚持以夷夏之辨为礼义之辨,没有狭隘的民族观念。《春秋明经》的天人感应说承自《胡传》,与刘基自己的天人感应观念有区别。《春秋明经》的著作年代应当在青年时期。  相似文献
