Knowledge and Forms in Plato's Educational Philosophy     

Mason Marshall 《Educational theory》2020,70(2):215-229

In this essay, Mason Marshall argues that Plato's views on Forms play a central role in his educational philosophy. In response to what certain commentators have recently written, Marshall contends that this interpretation not only is accurate but also is advantageous because of how it can help philosophy of education. He also addresses the view, proposed by one philosopher of education, that Plato believes that the most valuable sort of knowledge cannot be fully expressed in words and that the objects of this knowledge are something other than transcendent Forms. Preferable to that view, Marshall argues, is the idea that Plato wants knowledge of Forms which is nonrepresentational.  相似文献   

Professional knowledge or motivation? Investigating the role of teachers’ expertise on the quality of technology-enhanced lesson plans     

《Learning and Instruction》2020

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.  相似文献

贾苹  闫亚飞  郭文姣  刘细文  张超  彭皓  杨雨寒  赵婉雨 《图书情报工作》2021,64(24):24-31

[目的/意义] 随着自主创新战略的提出，科技信息和科技情报在国家科技发展中的基础性作用日益受到重视，开展区域创新和经济发展的信息服务研究与实践，构建面向区域创新和经济发展的信息服务方法体系、实施方案，是十分必要的。[方法/过程] 通过对国内外文献情报机构服务区域创新和经济发展的实践调研，以及中国科学院文献情报中心在"十二五"和"十三五"期间面向省级科学院、中国科学院转化中心、地方政府、园区企业开展区域信息服务的整体设计和服务实践与案例分析，总结归纳中国科学院文献情报中心开展区域创新和经济发展知识服务的特色和成效。[结果/结论] 在实践的基础上提出图书馆面向区域创新和产业发展提供信息服务，进一步拓展了图书馆的服务领域，是图书馆发展的一个生长点，并将在服务内容与服务方式上不断发展完善。  相似文献   

Self-derivation through memory integration: A model for accumulation of semantic knowledge     

《Learning and Instruction》2020

Semantic knowledge accumulates through explicit means and productive processes (e.g., analogy). These means work in concert when information explicitly acquired in separate episodes is integrated, and the integrated representation is used to self-derive new knowledge. We tested whether (a) self-derivation through memory integration extends beyond general information to science content, (b) self-derived information is retained, and (c) details of explicit learning episodes are retained. Testing was in second-grade classrooms (children 7–9 years). Children self-derived new knowledge; performance did not differ for general knowledge (Experiment 1) and science curriculum facts (Experiment 2). In Experiment 1, children retained self-derived knowledge over one week. In Experiment 2, children remembered details of the learning episodes that gave rise to self-derived knowledge; performance suggests that memory integration is dependent on explicit prompts. The findings support nomination of self-derivation through memory integration as a model for accumulation of semantic knowledge and inform the processes involved.  相似文献   

Teaching to discuss controversial public issues in fragile times: Approaches of Israeli civics teacher educators     

《Teaching and Teacher Education》2020

Civics teachers play a critical role in maintaining classroom environments that encourage discussions of controversial public issues. Thus, preparing new teachers to consider the role of such discussions is crucial. Building on theories of teacher knowledge development, this study explores how Israeli civics teacher-educators conceptualize discussions as part of their courses. The findings present four approaches that include: discussion as a pedagogical practice; discussion as a means for reflection; discussion as a way to bring the curriculum to life; and discussion as a vehicle that represents disciplinary content. Based on these findings, the role of discussion as an educational goal, not just a secondary means, will be argued.  相似文献

知识找回场景下推荐系统模拟实现及评价研究     

程秀峰  张孜铭  孟亚琪  范晓莹  杨金庆 《图书情报工作》2019,63(16):72-83

[目的/意义]信息过载一直是知识工作者在搜集、处理和创造知识的过程中所面临的主要困境。这种困境导致的结果之一是很难回忆起曾经使用过的文档的内容细节及具体位置，而推荐系统则能减少这样的困难。通过研究对比不同推荐系统在这一任务下的优缺点，可以帮助知识工作者更好地完成回忆任务。[方法/过程]基于相关理论，在同一场景（知识找回）模拟实现并测试了4种不同类型的推荐过程，包括基于内容的推荐CBR、基于协同过滤的推荐CFR、基于推理网络的推荐INR与融入了情境感知的推荐CAS，根据所确定的若干指标（精确性、情境相关性、预测性、多样性）对推荐效果进行比较。[结果/结论]结果显示，以上推荐系统在帮助用户回忆并找回文档过程中都有各自的优势，而基于情境感知的推荐系统在情境相关性与预测用户行为方面具有较好的效果。  相似文献   

Toward multimodal inquiry: opportunities,challenges and implications of multimodality for research and scholarship     

Ioana Literat  Anna Conover  Elizabeth Herbert-Wasson  Karen Kirsch Page  Joseph Riina-Ferrie  Rachael Stephens 《高等教育研究与发展》2018,37(3):565-578

In this article, we suggest that we are witnessing a challenge to the hegemony of text-based knowledge in academic scholarship, brought about by newly available modes of expression, and a cultural shift in our notions of reading and writing, authorship, and networked knowledge production. The central question we address here concerns the implications of widening our ideas of acceptable forms of inquiry, analysis and representation in academic scholarship. As a collective of scholar-practitioners exploring new modes of expression and working both within and outside the formal structures of academia, we argue for the increasing significance of multimodal research in the contemporary context of academic inquiry. By more equitably valuing different ways of thinking, knowing and communicating, multimodal research can facilitate wider and more diverse participation in the production of knowledge, offer a more nuanced and ethical mode of inquiry, emphasize different ways of knowing and connecting, and make scholarship more broadly accessible beyond academic contexts. Here, we analyze the key opportunities facilitated by multimodal inquiry, as well as the obstacles that stand in the way of a wider adoption of this type of research in higher education.  相似文献   

Understanding China as practicing Chineseness: selected cases of Vietnamese scholarship     

Chih-yu Shih 《Inter-Asia Cultural Studies》2018,19(1):40-57

The notion of post-Chineseness is enlisted to analyze Vietnamese Sinology as a comparative agenda. Post-Chineseness refers to the cultural preparation and the political process of mutual acknowledgement among those who consider one another sharing (some kind of) Chineseness, practically defined according to the context and its trajectories, at each time and each site. Chineseness can thus have various, if not entirely irrelevant, meanings. Vietnamese Sinologists have relied on different kinds of post-Chineseness to make sense of their relationship with the encountered Chinese to select and determine the mode of self-understanding, the purpose and a strategy to reconnect, and the normative criterion to assess and manage the relationship. Chinese Vietnamese are significantly less numerous than Chinese Malaysian, Thai, and Indonesians. However, the history of Vietnam is considerably closer to China than are those of Korea and Japan, in terms of length of merger. The post-Chineseness of Vietnamese scholarship therefore complicates its role-identity vis-à-vis China, intellectually as well as practically.  相似文献   

基于创新价值网的区域知识承载力评价研究     

张娜娜  胡斌  杨坤 《科技管理研究》2018,38(1)

区域知识承载力是区域创新可持续发展的重要标志,为了促进区域经济发展、科技创新的能力提高,本文从创新价值网的视角对区域知识承载力进行评价。首先从主体资源系统、科技创新系统、创新环境系统三个方面构建创新价值网,基于创新价值网的构造建立区域知识承载力评价指标体系。然后运用AHP-DEMATEL方法对各个指标设置权重,该方法将各个因素之间的影响度、被影响度融入到权重中,降低了单由专家打分评价的局限性。最后对“一带一路”沿线东南亚南亚国家的区域知识承载力进行实证分析,并根据实证结果提出相应建议。  相似文献
