Learning about the past: exploring the opportunities and challenges of using an outdoor learning approach     

Richard Harris  Helen Bilton 《Cambridge Journal of Education》2019,49(1):69-91

This paper examines the potential of outdoor learning for supporting children’s understanding of and attitude towards history. A class of primary school children participated in an intensive experiential, residential history programme. A range of data was collected before, during and after the residential programme, and the findings suggest that the experience had a positive impact on the children’s attitude towards history and enabled many of the children to be able to easily recall highly specific factual knowledge. However, the children’s understanding of history as a provisional construct was not developed, as it was not a strong feature of the programme. Nor was the experiential nature of the experience fully exploited. Overall the study suggests that such a programme has the potential to support children’s learning of the past, but a deeper understanding of history, drawing on the benefits of outdoor learning pedagogy, needs to be planned for more explicitly.  相似文献   

Legal Notes When May a College Regulate an Instructor's In-Class Speech? Recent Guidance from the Sixth Circuit     

Richard Fossey  Nathan Roberts 《Journal of Personnel Evaluation in Education》2001,15(4):329-335

In a recent opinion, the Sixth Circuit Court of Appeals ruled that a community college instructor has a constitutional right to utilize the words nigger and bitch in the context of a classroom discussion in a course on interpersonal relations. This article discusses this case in the context of other court decisions concerning a college's right to regulate an instructor's classroom speech. Implications for personnel evaluation in the higher education setting are discussed.  相似文献

Distributed leadership for personalized learning     

Julie M. Kallio  Richard Halverson 《Journal of Research on Technology in Education》2020,52(3):371-390

Abstract

Personalized learning refers to a collection of practices designed to place student interests and needs at the heart of schooling. Schools that implement personalized learning need leaders that support educators and students in redesigning the core practices of teaching and learning in K-12 schools. To answer the question of how leaders support this redesign, we use distributed leadership theory to focus on the macrotasks and microtasks that leaders enact to create the conditions for personalized learning practices. Drawing on a five-year, qualitative study of 11 personalized learning programs in the Midwest, we identify three macrotasks supporting personalized learning: reorganizing learning environments to support student voice and choice, assembling idiosyncratic technology ecosystems to distribute teaching and learning tasks, and redesigning instructional time to prioritize student’s interests, agency, and learning relationships. After we describe a number of microtasks associated with each macrotask, we discuss how a consideration of these kinds of leadership tasks can open the contemporary discussion of personalized learning from a narrow focus on learning technologies to an expansive vision of student-centered school reform.  相似文献   

A Methylome‐Wide Association Study of Trajectories of Oppositional Defiant Behaviors and Biological Overlap With Attention Deficit Hyperactivity Disorder          下载免费PDF全文

In 671 mother–child (49% male) pairs from an epidemiological birth cohort, we investigated (a) prospective associations between DNA methylation (at birth) and trajectories (ages 7–13) of oppositional defiant disorder (ODD), and the ODD subdimensions of irritable and headstrong; (b) common biological pathways, indexed by DNA methylation, between ODD trajectories and attention deficit hyperactivity disorder (ADHD); (c) genetic influence on DNA methylation; and (d) prenatal risk exposure associations. Methylome‐wide significant associations were identified for the ODD and headstrong, but not for irritable. Overlap analysis indicated biological correlates between ODD, headstrong, and ADHD. DNA methylation in ODD and headstrong was (to a degree) genetically influenced. DNA methylation associated with prenatal risk exposures of maternal anxiety (headstrong) and cigarette smoking (ODD and headstrong).  相似文献   

Virtual Reality Simulation: Effects on Academic Performance Within Two Domains of Writing in Science     

Lamb  Richard L.  Etopio  Elisabeth  Hand  Brian  Yoon  Sae Yeol 《Journal of Science Education and Technology》2019,28(4):371-381

The purpose of this study was to investigate the role textbooks can play on writing complexity and lexical density as a proxy for critical thinking and ultimately learning, in relation to argumentative and summative writing when integrated with a virtual reality experience. In this study, differences in writing complexity and lexical density scores were measured across four different pedagogical modalities: VR alone, VR followed by textbook readings, textbook readings followed by VR, and textbook readings alone. Adult students, recruited from non-science-based higher education programs, responded to two prompts related to content found in the VR environments and discussed in the textbooks. The authors hypothesized that exposure to a virtual marine environment prior to responding to the writing prompts would enhance both argumentative and summative writing products, when compared to participants who only had access to the textbook experiences. Participants who were exposed to the VR environment then a textbook demonstrated significantly greater writing complexity and lexical density scores than those who had access to VR alone, or access to the text alone.

The use and abuse of metatags     

Richard A. Spinello 《Ethics and Information Technology》2002,4(1):23-30

The web creates manyopportunities for encroachment on intellectualproperty including trademarks. Our principaltask in this paper is an investigation into anunusual form of such encroachment: theimproper use of metatags. A metatag is a pieceof HTML code that provides summary informationabout a web page. If used in an appropriatemanner, these metatags can play a legitimaterole in helping consumers locate information. But the ``keyword'' metatag is particularlysusceptible to manipulation. These tags can beeasily abused by web site creators anxious tobait search engines and bring scores ofvisitors to their sites. The law aboutmetatags is far from settled and many legalscholars are uncomfortable with the conclusionthat the unauthorized use of a trademark in ametatag represents infringement. How should weassess this practice known as ``spamdexing'' froma normative perspective? Is it commercial fairplay or something more sinister? We make thecase here that there are salient moral problemswith spamdexing since it exploits thereputational goodwill of trademark owners andconfuses consumers. It violates basic moralduties and it flouts the golden rule principle. Hence unauthorized use of a competitor'strademark in a metatag is not morallyacceptable.  相似文献   

Externalities, technological complementarities and sustained economic growth     

Kenneth I. Carlaw  Richard G. Lipsey   《Research Policy》2002,31(8-9)

Externalities as conventionally defined miss many of the spillovers that are both causes and consequences of the technological changes that underlie economic growth. We introduce a much wider concept called technological complementarities. New general purpose technologies (GPTs) rejuvenate the growth process by creating technological complementarities, which are adequately measured neither by total factor productivity (TFP) nor by externalities. There would be major gains from technological change even if the returns on capital invested in innovation never exceeded the returns on investing in existing technologies so that there were neither externalities nor positive changes in TFP.  相似文献   

The role of social embeddedness in professorial entrepreneurship: a comparison of electrical engineering and computer science at UC Berkeley and Stanford   总被引：1，自引：0，他引：1  

Martin Kenney  W Richard Goe 《Research Policy》2004,33(5):691-707

Professorial entrepreneurship has recently attracted much attention. This paper draws upon historical research, a survey of faculty, and an Internet-based methodology for identifying professorial affiliations with entrepreneurial firms at two of the premier electrical engineering and computer science departments in the US, The University of California, Berkeley and Stanford. We employ the concept of “nested embeddedness” to explain why the faculty members in these two institutions have different levels of entrepreneurship and corporate involvement. EE&CS faculty at both universities were found to be socially embedded in departments and disciplines that supported and placed value on entrepreneurial activities. However, while being embedded in a university environment with a history of success and high level of support for entrepreneurship, EE&CS faculty at Stanford had a significantly greater level of corporate involvement, including the founding of start-ups. Although significantly less than Stanford, the level of corporate involvement among EE&CS faculty at Berkeley was also substantial. This suggests that being embedded in an academic department and disciplines with cultures that are supportive of entrepreneurial activity can help counteract the disincentives created by a university environment that is not strongly supportive of these activities.  相似文献
