Educación bilingüe del alumnado sordo: pilares para un cambio estratégico

Pese a los progresos logrados en la protección de los derechos fundamentales de salud y educación de las personas sordas usuarias de las lenguas de signos, a menudo se sigue negando a niños sordos su derecho a aprender y usar las lenguas de signos en su educación y en entornos físicos y psicosociales accesibles de conformidad con la Convención de los Derechos de las Personas con Discapacidad (CDPD) y con las recientes leyes 27/2007 y 17/2007. El objetivo principal de este estudio fue obtener información sobre los factores estratégicos que favorecen una escuela saludable e inclusiva, mediante programas de educación bilingüe sostenibles y de calidad para escolares sordos en España. La metodología utilizada consistió en un estudio descriptivo con componentes de investigación-acción participativa y un enfoque de análisis estratégico. Como resultados, cabe destacar que las principales macrotendencias que, en el ámbito internacional, han promovido el cambio hacia prácticas bilingües son dos: en primer lugar, los cambios sociales y políticos que tienden a una creciente aceptación de la diversidad y los temas relacionados con las personas sordas; y en segundo lugar, una tendencia a un activismo, una autoconciencia y un apoderamiento crecientes por parte de las personas sordas. Como contrapartida, las que lo han obstaculizado son, por un lado, la visión de la sordera como una condición médica, que puede solucionarse mediante la tecnología; y por otro lado, el fonocentrismo, unido a una cierta resistencia social a lo desconocido. Aunque en España algunas de las escuelas que han iniciado el cambio cumplen las recomendaciones de la CDPD, la mayoría están todavía en una fase preliminar de formulación o puesta en práctica de este nuevo modelo y distan mucho de encontrarse distribuidas de manera igualitaria en las diferentes comunidades autónomas. Como conclusión podemos decir que conseguir una educación más saludable e inclusiva para los escolares sordos implica poner en marcha una estrategia de actuación planificada en la que participen activamente todos los sectores y organismos relevantes implicados y, en particular, las comunidades sordas a través de las organizaciones que las representan. Sin un cambio radical de perspectiva, la salud y la educación no serán accesibles a todos y las desigualdades sociales se verán acentuadas.

Enhanced electro-oxidation resistance of carbon electrodes induced by phosphorus surface groups

The electro-oxidation of carbon materials enormously degrades their performance and limits their wider utilization in multiple electrochemical applications. In this work, the positive influence of phosphorus functionalities on the overall electrochemical stability of carbon materials has been demonstrated under different conditions. We show that the extent and selectivity of electroxidation in P-containing carbons are completely different to those observed in conventional carbons without P. The electro-oxidation of P-containing carbons involves the active participation of phosphorus surface groups, which are gradually transformed at high potentials from less-to more-oxidized species to slow down the introduction of oxygen groups on the carbon surface (oxidation) and the subsequent generation of (C*OOH)-like unstable promoters of electro-gasification. The highest-oxidized P groups (–C–O–P-like species) seem to distribute the gained oxygen to neighboring carbon sites, which finally suffer oxidation and/or gasification. So it is thought that P-groups could act as mediators of carbon oxidation although including various steps and intermediates compared to electroxidation in P-free materials.

3D teaching: the ideal complement for professionals in design and construction

Today, the requirement of professional skills to university students is constantly increasing in our society. In our opinion, the content offered in official degrees need to be nourished with different variables, enriching their global professional knowledge in a parallel way; that is why, in recent years, there is a great multiplicity of complementary courses at university. One of the most socially demanded technical requirements within the architectural, design or engineering field is the management of 3D drawing software, becoming an indispensable reality in these sectors. Thus, this specific training becomes essential over two-dimension traditional design, because the inclusion of great possibilities of spatial development that go beyond conventional orthographic projections (plans, sections or elevations), allowing modelling and rotation of the selected items from multiple angles and perspectives. Therefore, this paper analyzes the teaching methodology of a complementary course for those technicians in the construction industry interested in computer-aided design, using modelling (SketchupMake) and rendering programs (Kerkythea). The course is developed from the technician point of view, by learning computer management and its application to professional development from a more general to a more specific view through practical examples. The proposed methodology is based on the development of real examples in different professional environments such as rehabilitation, new constructions, opening projects or architectural design. This multidisciplinary contribution improves criticism of students in different areas, encouraging new learning strategies and the independent development of three-dimensional solutions. Thus, the practical implementation of new situations, even suggested by the students themselves, ensures active participation, saving time during the design process and the increase of effectiveness when generating elements which may be represented, moved or virtually tested. In conclusion, this teaching-learning methodology improves the skills and competencies of students to face the growing professional demands of society. After finishing the course, technicians not only improved their expertise in the field of drawing but they also enhanced their capacity for spatial vision; both essential qualities in these sectors that can be applied to their professional development with great success.

Workshops in “Construction of Structures I”: A new teaching methodology in the Building Engineering Degree

Both the current economic situation in the construction sector and the continuous normative changes in the building area imply the use of new methodologies to enhance students’ competences in the degree of Building Engineer. The aim of this paper is to present, analyse and discuss the development of constructive workshops as a new teaching methodology used in the subject of Construction of Structures I at the University of Alicante to complement the constructive and technical knowledge acquired by our students and to enhance their communicative and representation skills essential for their professional practice in the future. The used methodology is based on the development of three-dimensional construction details (in groups of 3 or 4 students) to be shown in two A1-pannels exposed in the corridors of the Polytechnic School. Thus, students’ work approaches constructive problems in a global way by discussing simultaneously with teachers and other groups about the most suitable solution on each case. This contribution has multiperspective results and improves criticism of students in different areas, encouraging new learning strategies and active participation. What is more, on-line information and web applications have been used to prepare and organize this kind of workshops, allowing students to use new technologies as a complementary learning methodology. In conclusion, the use of these new workshops in the Degree of Building Engineer stimulates an interactive class versus a traditional lecture where the participative groups´ attitude and the development of oral presentations dissolve the traditional boundaries regarding public communication skills of the students in the Degree.

Assessing participation in online discussion forums: a proposal for multidimensional analysis

This paper aims to assess the discussion forums being used in the programme Especialista Universitario online sobre Tecnologías de la Información y la Comunicación, taught at the University of Alicante, on the basis of the analysis model suggested by Kay (2004). In such a model, it is essential to represent graphically the forum activity so that the visual representation may improve analysis. This research has allowed reaching results which define the forum activity and has contributed with a proposal for multi analysis in the area of assessing participation in communication within online discussion forums.

Active oxygen by Ce–Pr mixed oxide nanoparticles outperform diesel soot combustion Pt catalysts

A Ce0.5Pr0.5O2 mixed oxide has been prepared with the highest surface area and smallest particle size ever reported (125 m2/g and 7 nm, respectively), also being the most active diesel soot combustion catalyst ever tested under realistic conditions if catalysts forming highly volatile species are ruled out. This Ce–Pr mixed oxide is even more active than a reference platinum-based commercial catalyst. This study provides an example of the efficient participation of oxygen species released by a ceria catalyst in a heterogeneous catalysis reaction where both the catalyst and one of the reactants (soot) are solids. It has been concluded that both the ceria-based catalyst composition (nature and amount of dopant) and the particle size play key roles in the combustion of soot through the active oxygen-based mechanism. The composition determines the production of active oxygen and the particle size the transfer of such active oxygen species from catalyst to soot.
