La incidencia de las competencias lingüistícas del escolar sobre las adquisiciones escolares en las demás áreas del currículum es una realidad que todos los maestros pueden comprobar día a día. En este trabajo se investiga esa incidencia, medida a través de la variable fracaso escolar, y sus resultados podrían permitir extraer algunos principios de intervención educativa precoz en algunos aspectos del lenguaje cruciales para la escolaridad posterior. 相似文献

This paper describes research on the use of knowledge models (ontologies) for building computer-aided educational software in the field of control engineering. Ontologies are able to represent in the computer a very rich conceptual model of a given domain. This model can be used later for a number of purposes in different software applications. In this study, domain ontology about the field of lead–lag compensator design has been built and used for automatic exercise generation, graphical user interface population and interaction with the user at any level of detail, including explanations about why things occur. An application called Onto-CELE (ontology-based control engineering learning environment) uses the ontology for implementing a learning environment that can be used for self and lifelong learning purposes. The experience has shown that the use of knowledge models as the basis for educational software applications is capable of showing students the whole complexity of the analysis and design processes at any level of detail. A practical experience with postgraduate students has shown the mentioned benefits and possibilities of the approach. 相似文献

This article discusses the results of a qualitative case study that examined how school district language policies impact humanizing practices in a high school ESL program. The theoretical framework builds on Paulo Freire's concept of humanizing pedagogy to explore policy and instruction in a secondary ESL program. Participants of this study include school district officials and high school ESL teachers. Findings indicate that when ESL teachers adhere to rigid language policies, they fail to create humanizing practices in their classrooms. In contrast, when teachers do not hold themselves strictly accountable to the institutionalized discourse of ESL, they are able to enact humanizing practices where students' linguistic and cultural resources are validated as essential for the development of academic resiliency. Paradoxically, even teachers who enact humanizing practices fail to question district language policies that render students cultural and linguistic resources invalid. 相似文献

Carreras en Salud (Careers in Health) provides bilingual/bicultural individuals with a fully-supported customized career path for nursing and other allied health occupations bridging individuals from unemployment/underemployment to high-demand healthcare positions. Healthcare providers, elected officials, and community leaders have partnered with the collaboration and supported the initiative in its various stages. 相似文献

Abstract This article reports a preliminary study of high school students making sense of the behavior displayed by a Lorenzian Water Wheel. The Lorenzian Water Wheel is a rotating disk driven by the flow of water whose motion may be periodic or not, depending on different parameters (e.g., tilt of the wheel, flow rate of the water, and amount of friction). The study aims to contribute toward new basis for the learning of dissipative dynamics through the analysis and experimentation with common phenomena. The study also aims to support the design of learning environments that focus on fundamental aspects of dissipative dynamics‐such as the origins of turbulence, the relationships between periodicity and predictability, or the notion of an attractor—by refining intuitions that emerge from the daily experience with the surrounding world. 相似文献

The methodology of protecting the European stained glass windows against environmental risk (e.g. meteorological factors, air pollution, microorganisms) by means of an external glazing is not new. In spite of many scientific studies carried out in the last 20 years, some questions were still up for discussion. The European VIDRIO (2002–2005) project gave an answer to these questions. The research carried out by the different project partners established a new multidisciplinary approach aimed at evaluating the efficiency of the protective glazing systems and their effects on stained glass windows conservation, and finally at assessing the most appropriate strategy to preserve stained glass windows. Scientific results showed that the so-called isothermal glazing (i.e. ventilation by the air coming from the inside of the building) protected efficiently the ancient stained glass window from environmental attack (i.e. rain, pollutants, condensation, thermal shocks) with very limited secondary effects. The scientific research highlighted that its efficiency was strongly related to the technical design of the protective system. In particular, the ventilation and the size of the interspace had to be carefully considered. The research developed within the VIDRIO project was turned into general recommendations to the owners and practitioners on the best practice for the stained glass windows future conservation. 相似文献

ABSTRACTThis article examines the role that business librarians can play in conveying the importance of thorough patent research in the start-up life cycle. It provides a summary of the components of the start-up life cycle and due diligence research as it pertains to entrepreneurs and venture capitalists. An overview of patent research resources and locations is provided, with particular focus on PatentsView, a web-based patent data visualization and analysis tool. 相似文献

ABSTRACT There is a gap in research on access to universities in South Africa. The research that exists focuses on quantitative methodologies, although some qualitative studies are now emerging. These research methodologies, although necessary and substantial for the development of equity measures and policies, might be less successful in their impact on the local context, on research participants and in expanding what counts as knowledge in the university. In this paper, participatory research, which has not been used to research access, is explored. The paper seeks to go beyond the instrumentalization of research participants – especially those from low-income households – highlighting the potential of using multi-strategy research, in which participatory elements are included as a way to foster both participants’ human development and local impact. Drawing on a research project on access to higher education in South Africa, the paper demonstrates that by including participatory elements (in this case photovoice) has the potential to operationalize Appadurai’s notion of the ‘right to research’ among undergraduates. Using data, including processes, observations, workshops, interviews, and visual narratives from a participatory photovoice project, the findings highlight how methodological plurality creates space for locally and relevant knowledge production, challenging epistemic barriers and fostering human development among the research participants. 相似文献

Bearing in mind students' misconceptions about basic concepts in astronomy, the present study conducted a series of constructivist activities aimed at changing future elementary and junior high school teachers' conceptions about the cause of seasonal changes, and several characteristics of the Sun–Earth–Moon relative movements like Moon phases, Sun and Moon eclipses, and others. The activities and results concerning the cause of seasonal changes are reported. Both the experimental class and the control groups improved their grasp of basic astronomy concepts statistically significantly, although the experimental class made the most impressive progress of all. Regarding subjects relevant to this study (seasonal changes), only the experimental class showed a statistically significant improvement, which justifies the constructivist approach. We conclude that in implementing a reform in the science curriculum, the change has to include the subjects taught and also the way they are taught. © 2006 Wiley Periodicals, Inc.
