Criterios para educar moralmente en una sociedad democrática y plural     

Josep M.a Puig 《Cultura y Educación》2013,25(15):5-12

El autor plantea la necesidad actual de la Educación Moral, a nivel social y la conveniencia de que la escuela se ocupe de ella de forma intencional y sistemática. Señala, además, las implicaciones que un currículum de Educación Moral conlleva en la vida de la escuela a través de la participación democrática. Insiste en la necesidad de completar un currículum como el propuesto, con acciones que supongan participación en proyectos de trascendencia social.  相似文献

A Study of the Use of Ontologies for Building Computer-Aided Control Engineering Self-Learning Educational Software     

Isaías García  Carmen Benavides  Héctor Alaiz  Angel Alonso 《Journal of Science Education and Technology》2013,22(4):589-601

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   

English or Nothing: The Impact of Rigid Language Policies on the Inclusion of Humanizing Practices in a High School ESL Program     

María del Carmen Salazar 《Equity & Excellence in Education》2013,46(3):341-356

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

The Role of Community College First-Year Experience Programs in Promoting Transfer Among Latino Male Students     

Mauro Ivan Peña 《Community College Journal of Research & Practice》2013,37(3):186-200

ABSTRACT

A qualitative case study approach was used to examine Latino male students and First-Year Experience (FYE) programs aimed at promoting student transfer. Two FYE programs at two community colleges in California were studied: Bridgetown Community College and Portlake Community College (pseudonyms). Study participants included four groups: Latino male FYE students, Latino male FYE alumni, FYE counselors, and FYE coordinators. Data collection strategies included semi-structured interviews, site observations, and document analysis. Analysis of data involved both deductive and inductive approaches, and resulted in identification of four findings critical to the success of FYE programs and their work with Latino males: (a) the need to support help-seeking behaviors, (b) the need to address the “long journey” to transfer, (c) the need to support students’ work burden and financial constraints, and (d) the need to incorporate approachable and culturally responsive practices. Overall, the study offers insights into how community colleges might strengthen transfer support for Latino males through FYE programs.  相似文献

Determinants of cultural and popular celebration attendance: the case study of Seville Spring Fiestas     

María Luisa Palma  Luis Palma  Luis Fernando Aguado 《Journal of Cultural Economics》2013,37(1):87-107

The Spring Fiestas in Seville (Spain) (SFS) are the most important cultural events in the city each year. The present paper pursues two aims. The first is to characterize the SFS as a new prototype of a complex cultural good that expresses the link between the people and the place in which they live based on material and immaterial cultural heritage represented through popular celebrations. The second goal is to conduct an empirical analysis of the determinants that shape attendance intensity by estimating a zero-truncated count data model using a unique dataset of attendees at the SFS in 2009. Findings indicate that attendance is strongly associated with variables reflecting knowledge, institutional links, past experiences, and the perceived external benefits generated by the existence of the SFS. The article contributes to the literature by exploring participation in popular celebrations, a field of inquiry that to date is extremely limited in cultural economics.  相似文献   

Granite desalination using electromigration. Influence of type of granite and saline contaminant     

Jorge Feijoo  Xosé Ramón Nóvoa  Teresa Rivas  María Jesús Mosquera  Javier Taboada  Cristina Montojo  Fernando Carrera 《Journal of Cultural Heritage》2013,14(5):365-376

We describe the results of electromigration desalination of two soluble salt-contaminated Galician granites. The efficacy of electromigration, which had not been previously applied to granite, was assessed for two types of granite contaminated with a 20% NaCl solution and seawater. Desalination effectiveness was evaluated as follows: (1) analysis of anode and cathode ion content during testing; (2) analysis of ions at different distances from the electrodes after testing; (3) pH assessment of the stone surfaces; and (4) evaluation of colour changes. Results were very satisfactory; by the end of testing, chloride was reduced by almost 100% in both the NaCl and seawater contaminated samples. Sulfate reduction was also significant, despite this ion's lower mobility. The granite pH values remained close to neutral and colour changes were minimal. The difference in effectiveness of the process for the two types of stone was associated with their dissimilar pore structure.  相似文献   

Visual function,performance, and processing of basketball players vs. sedentary individuals

BackgroundAthletes tend to have better visuo-motor performance than do sedentary individuals. However, several basic visual-function and perceptual parameters remain unexplored to date. In this study, we investigated whether differences exist in visual function, performance, and processing between basketball players and individuals without a sport-involvement background.MethodsA total of 33 healthy men with no visual impairment or pathology were divided into 2 groups, depending on the involvement in sport (semi-professional basketball players and sedentary individuals). We tested their baseline heart-rate variability in the resting position apart from subjective questionnaires to determine their physical fitness level, and we checked their visual function, performance, and processing through an extended battery of optometric tests.ResultsThe 2 groups differed in resting heart-rate variability parameters (p < 0.001), confirming their dissimilarities in regular time practising sports per week. The basketball players showed a closer breakpoint and recovery nearpoint of convergence, a higher fusional-vergence rate, better discriminability halos, and better eye–hand coordination (all p values < 0.05).ConclusionThese results show evidence that athletes, basketball players in this case, exhibit better performance in several visual abilities in comparison to a group of individuals without sporting backgrounds, suggesting an improvement due to the systematic involvement of those skills during basketball practice.  相似文献
