Generation of virtual models of cultural heritage     

Amparo Núñez Andrés  Felipe Buill Pozuelo  Joaquín Regot Marimón  Andrés de Mesa Gisbert 《Journal of Cultural Heritage》2012,13(1):103-106

Different techniques and tools currently exist to generate three-dimensional models of small elements, buildings and cities. Apart from being easier to interpret than two-dimensional drawings, these models facilitate data necessary for reconstruction projects, preservation or rehabilitation of the architectural or archaeological heritage. Traditional surveying only enables us to obtain discrete information of the characteristic lines that define each surface, edge, slope change etc. whereas work with massive capture techniques allows us to obtain continuous points of the surfaces. Photogrammetry or laser scanning combined with conventional photography provides information of the building in addition to its geometry. We carried out a review of the different techniques showing the advantages and disadvantages of each technique as well as the information that can be obtained by applying these techniques to the survey of the great Gate of Antioch in the town of Aleppo, declared a World Heritage Site by UNESCO in 1986, in Syria.  相似文献   

Differences between web sessions according to the origin of their visits     

José Luis Ortega  Isidro Aguillo 《Journal of Informetrics》2010,4(3):331-337

The aim of this paper is to characterize the distribution of number of hits and spent time by web session. It also expects to find if there are significant differences between the length and the duration of a session with regard to the point of access–search engine, link or root. Web usage mining was used to analyse 17,174 web sessions that were identified from the webometrics.info web site. Results show that both distribution of length and duration follow an exponential decay. Significant differences between the different origins of the visits were also found, being the search engines’ users those who spent most time and did more clicks in their sessions. We conclude that a good SEO policy would be justified, because search engines are the principal intermediaries to this web site.  相似文献

From the disjunction between passive and active instruction approaches towards their integration as an alternative for the significant learning of sustainable development / De la disyuntiva entre los enfoques de instrucción pasiva y activa hacia su integración como alternativa para un aprendizaje significativo del desarrollo sostenible

Abstract

This study aims to show how the integration of passive and active learning approaches contributes towards the significant understanding of problems associated with sustainable development. To do this, a case study from the municipality of San Miguel de Achiutla in Oaxaca, Mexico, is used as a general method, with the specific procedure including an instrument based on secondary sources representing the passive learning phase, as well as an instrument created on the basis of primary sources, designed in relation to the active learning component. The passive learning phase enabled us to identify variables pertaining to the highly vulnerable dimensions of sustainable development, and to also detect areas in which there is a deficit of information, since not all data are available, while the active learning phase revealed the causes of vulnerability from the perspective of different agents, including those who experienced the issues directly. In view of the above, we conclude that rather than being exclusive, these two different approaches should in fact be complementary.  相似文献

La formación permanente del profesorado de Lengua y Literatura: Modelos teóricos y actuación del asesor     

Luis González 《Cultura y Educación》2013,25(9):45-56

En este artículo se reflexiona sobre el papel del educador y del asesor de formación, al que se propugna más activo y centrado en la disciplina. Desde esa base se pasa a una segunda reflexión centrada en el papel de las ciencias del lenguaje en la educación en que se trata de establecer un puente entre los requerimientos del saber disciplinar y teórico sobre el lenguaje y los de las situaciones, textos y contextos reales de uso del lenguaje. Se trata una vez más de la vieja necesidad de articular en la ciencia y en la educación el rigor y la relevancia.  相似文献   

Informatica aplicada a la comprensión textual     

Luis Guerra  Juan Martín 《Cultura y Educación》2013,25(13):95-99

Uno de los inconvenientes de los programas didácticos que tratan de desarrollar en el alumno estrategias de comprensión lectora es que, dada la estructura grupal de la clase, deben aplicarse colectivamente cuando su propia naturaleza requeriría la aplicación individual. El ordenador puede conseguir aplicar a toda una clase los mismos modelos de comprensión, pero individualizadamente. En este artículo se expone un modelo experimental.  相似文献   

The reality of virtual worlds: pros and cons of their application to foreign language teaching     

Paloma Garrido-Iñigo  Francisco Rodríguez-Moreno 《Interactive Learning Environments》2013,21(4):453-470

This article presents our experience of testing the OpenSim platform as a tool in teaching French to 108 tourism students at Universidad Rey Juan Carlos (Madrid, Spain). The article begins with some theoretical reflections on the behaviour of the student when using a virtual platform by means of an avatar, and with our observations of how this doubling of identity is actually the greatest asset of virtual worlds when we intend to apply them to teaching (1. Introduction). Then we move on to present our goals and method of work (2. Aims and methodology) and to analyse the development of the virtual space or sim, setting out the teaching strategies that were employed in each of the islands we created, and which correspond to reading comprehension, listening comprehension and written expression (3. Metaverse design). In order to assess the language learning results, we also devised tests throughout the experiment, which were repeated one month later. The assessment shows that the process of language acquisition is positive (4. Results analysis). Finally, we demonstrate that the rise of virtual worlds has been backed up by psycholinguistic factors, but at the same time their applicability and sustainability depend on technical aspects and very especially on theoretical and pedagogical tenets which are still to be drawn up (5. Conclusions).  相似文献

TRANSFER RATES AMONG STUDENTS FROM RURAL,SUBURBAN, AND URBAN COMMUNITY COLLEGES: WHAT WE KNOW,DON'T KNOW,AND NEED TO KNOW     

Cindy Castañeda 《Community College Journal of Research & Practice》2013,37(5):439-449

During the past decade much thought has been given to the merits and weaknesses of different ways of calculating transfer rates. This debate, although legitimate and necessary, has not led to research on transfer rates among colleges in different geographic locations. Furthermore, the lack of consensus and sometimes neglect in defining geographic location has reduced the reliability of the data that do exist. This article examines what is known about transfer rates by geographic location and what remains to be studied. Findings on differences by ethnic group and location also are presented. Although there are indications that students from rural areas differ from their urban and suburban counterparts, there has been little work that explores the impact of those differences on transfer rates. The need for further research on transfer rates and college location is also addressed.  相似文献
