This study addresses the problem of designing an appropriate learning space or architecture for distributed online courses using net-based communication technologies. We apply Wenger's criteria to explore, identify and discuss the design architectures of two online courses from two comparable online Master's programmes, developed and delivered in two different educational cultures, Ireland (MIC) and Denmark (OL). The investigation will take the shape of a discussion of the 'walls of the learning spaces' of the two courses, with reference to Wenger's criteria and values for an appropriate learning architecture. In an earlier evaluation study, both courses were deemed to be examples of online learning communities of practice, despite their geographical and cultural diversity in contexts of development. The findings of the present study confirm and document several significant design elements of the two courses, which are stressed in the design criteria suggested by Wenger as being vital for community building. 相似文献

While it is known that the process of becoming literate begins in early childhood and usually involves several years of schooling, research related to cognitive characteristics has been done mostly on illiterate adults, and information concerning illiterate children is therefore limited. The aim of the present study, involving 21 illiterate and 22 literate Mexican children aged 6 to 13, was to investigate the effects of literacy on neuropsychological characteristics during childhood. The children??s performance on 16 cognitive domains of the Evaluación Neuropsicológica Infantil (ENI, Child Neuropsychological Assessment) was examined in three mixed within- and between-groups profile analyses. The results suggest that the effect of literacy observed in adults is already evident in children in almost every task analysed. Moreover, the fact that an age effect was detected for the calculation abilities suggests that maths learning is school- and environment-dependent. 相似文献

En este artículo los autores recurren a voces de personajes chicanos para analizar y discutir la opresión lingüística del méxico americano durante las décadas de 1920 a 1960. Utilizando la teoría racial crítica y la teoría latina del racismo (CRT y LatCrit por sus siglas en inglés) los autores hacen referencia específica a pasajes, documentos históricos y piezas de la literatura para argumentar que cuestiones de poder y racismo han impactado la restricción en el uso del idioma español en los Estados Unidos. De manera específica, se hace referencia a los castigos sufrido por varias generaciones de hispanoparlantes.
In this article, the authors analyze and discuss the linguistic oppression faced by Mexican-Americans from the 1920s to the 1960s as narrated by Chicano voices. Critical Race Theory and Latino/a Critical Race Theory permeate the argument that issues of power and racism have impacted the use of Spanish in the United States. This oppression is reflected in historical documents, passages, and segments of Chicano literature. Specifically, the article describes instances of punishment suffered by several generations of Spanish speakers. 相似文献

We present the Aula EspaZio Gela, a facility dedicated to teaching Space Science and Technology at the master and doctorate level at the University of the Basque Country (Spain), and to promoting the development of this field in both public and private sectors. The one-year master's degree in Space Science and Technology (60 ECTS (European Credit Transfer and Accumulation System)) offers a group of compulsory courses which give way afterwards to a set of elective matters in which students choose one of two tracks: the scientific, primarily oriented to basic research at the University, or the technological, leading to the space industry and space agencies. After completion of the master thesis, our students have direct access to a PhD in both curricular lines. Here we detail the main features of the master's degree and the experience acquired in three years, including a comparative opinion survey to the students. We also describe the facilities at the Faculty of Engineering consisting of a specific classroom (Aula EspaZio Gela), an Astronomical Observatory, and different laboratories. 相似文献

Many engineering undergraduates begin third-level education with significant deficiencies in their core mathematical skills. Every year, in the Dublin Institute of Technology, a diagnostic test is given to incoming first-year students, consistently revealing problems in basic mathematics. It is difficult to motivate students to address these problems; instead, they struggle through their degree, carrying a serious handicap of poor core mathematical skills, as confirmed by exploratory testing of final year students. In order to improve these skills, a pilot project was set up in which a ‘module’ in core mathematics was developed. The course material was basic, but 90% or higher was required to pass. Students were allowed to repeat this module throughout the year by completing an automated examination on WebCT populated by a question bank. Subsequent to the success of this pilot with third-year mechanical engineering students, the project was extended to five different engineering programmes, across three different year-groups. Full results and analysis of this project are presented, including responses to interviews carried out with a selection of the students involved. 相似文献

Thirteen samples of an efflorescence collected from the surface of beeswax seals or from beeswax used for their restoration were analysed in detail. The samples were of different origin, age and storage history. The composition and the incidence of the efflorescence was correlated with a chemical composition of historical and recent beeswax samples. The composition of the crystalline layer was found to be very similar in all the samples. Linear monounsaturated alkenes containing 31 and 33 carbon atoms, more precisely (Z)-hentriacont-10-ene and (Z)-tritriacont-10-ene, were identified as main components. The analyses of beeswax have revealed that all compounds identified in “wax bloom” naturally occur in recent beeswax. However, the historical beeswaxes contained only traces of unsaturated hydrocarbons, if anything. The efflorescence was observed primarily on the surfaces of those samples which contained larger proportion of alkenes. The presented results could be of particular importance not only for better understanding of the described phenomenon, but also for the development of new beeswax-based materials, which would be “bloom resistant” and useful for conservation purposes. 相似文献
