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

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   

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   

上海“体教结合”举措下竞技体育后备人才“学生-运动员”双重角色的认同、冲突与转化          下载免费PDF全文

侯爽 《体育科研》2019,(3):30-37

“体教结合”是解决当前我国竞技体育发展问题的重要途径和举措。传统的体育后备人才培养模式只重视专项体育技能的发展而忽视了文化教育的重要性，不利于个体的全面发展。“体教结合”更重视人的全面发展，体育与教育的融合，使得竞技体育人才逐渐从运动员这一单一角色向“学生-运动员”双重角色转变。研究以角色认同为切入口，探讨上海“体教结合”举措下，角色的转变对体育竞技后备人才的影响。选取上海体育学院中国乒乓球学院少年班学员作为“学生-运动员”样本，选取国家乒乓球青年队及部分省市队队员作为职业运动员样本，使用结构化心理测量工具，对比两类受访者在运动与学业上的角色认同、心理倦怠与动机变量的差异。得出：在上海“体教结合”举措下，竞技体育后备人才认同“学生-运动员”双重角色，他们在学业任务中的卷入程度更高；双重角色使运动员在运动任务与学业任务上的主观价值感存在差异，表现出双重角色之间的冲突，但对个体的整体人生规划并不冲突；双重角色之间的转化，对于“学生-运动员”的心理健康存在促进效应。  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
