<span>En el presente trabajo se dan a conocer los resultados de una investigación sobre el curriculum oculto de la química. Con la participación de diversos profesores e investigadores de 10 países bajo la coordinación de un grupo de la Universidad de Utrech, en Holanda, se llegó a la conclusión de que hay una visión dominante de la química escolar en la que: La educación química normal está aislada del sentido común, de la vida cotidiana, de la sociedad, de la historia y filosofía de la ciencia, de la tecnología, de la física escolar y de la investigación química actual. Como resultado de lo anterior se inicia una discusión sobre lo que debe estar contenido al interior de un curriculum para que pueda denominarse química.</span>
The proposal and development of tourism projects need previous studies that demonstrate their potential, facilitate the analysis of data and decision making. Since the expansion of tourism in the 1960s, different methodologies have been developed that have sought to study the capabilities of the territories and, in turn, have offered a theoretical framework that supports their results. On the one hand, the objective of this work is to analyze existing models of potentiality and their evolution, and on the other hand, offer an index of potentiality calculation that takes into account physical and human aspects and pay attention to late medieval heritage of the province of Cá diz (Spain).
<p>Inmersos en la sociedad de la información se produce a una "vulgarización arqueológica" que afecta a los ámbitos más diversos. La televisión, el cine y los vídeo-juegos emplean representaciones tridimensionales del patrimonio con objeto de situar en ellos las aventuras. En muchos casos se trata de "imágenes falsas" que se han creado sin bases fiables. Desde ese punto de vista, la realidad virtual puede suponer un "peligro" de falseamiento de la propia realidad y en cierto modo puede perjudicar las posibilidades de representación técnica de las nuevas tecnologías. En este sentido, establecer proto colos de actuación que garanticen la fidelidad e integridad de los datos reales es una responsabilidad de los investigadores de nuestra área de conocimiento.</p>
El presente estudio pretende evaluar el desarrollo de una intervención docente en una unidad didáctica y comprobar su efecto sobre diferentes variables motivacionales a nivel situacional, a partir de las premisas de la teoría de las metas de logro (Nicholls, 1989) y de la teoría de la autodeterminación (Ryan & Deci, 2002). Se realizó un estudio cuasi-experimental a lo largo de una secuencia de tres unidades didácticas integradas en la programación didáctica anual del profesor de EF. En la unidad experimental de salto con combas se aplicaron una serie de estrategias vinculadas a las áreas TARGET (Ames, 1992) y en las dos unidades control no hubo ningún tipo de manipulación en la intervención. En el estudio participaron un total de 92 alumnos de 1º de Educación Secundaria Obligatoria, con edades comprendidas entre los 11 y 14 años. Los instrumentos utilizados midieron al final de las tres unidades didácticas distintas variables situacionales: el clima motivacional, las necesidades psicológicas básicas, la motivación autodeterminada y la diversión. Los resultados mostraron en la unidad didáctica experimental, respecto a las unidades control, una mayor percepción del clima tarea, una mayor satisfacción de las necesidades psicológicas básicas, una mayor motivación autodeterminada y una mayor diversión en el alumnado. Por tanto, la eficacia de esta intervención refleja la importancia de implementar estrategias relativas a las áreas TARGET en las clases de Educación Física para generar un clima tarea, influyendo de esta forma en la motivación y diversión de los alumnos. Palabras clave: intervención docente; motivación del alumnado; necesidades psicológicas básicas; diversión; educación física; áreas TARGET.Abstract: This study aims to evaluate the development of a teacher intervention in a didactic unit and to check their effect on different motivational situational variables, based on the achievement goal theory (Nicholls, 1989) and the self-determination theory (Ryan & Deci, 2002). We proposed a quasi-experimental study during a sequence of three didactic units which belong to the physical education program. A series of strategies connected with TARGET areas were applied in the experimental jumping rope unit and there wasn´t any kind of manipulation in the intervention in the two control units. In this study, 92 Physical Education 1st year compulsory secondary education students, aged between 11 and 14 years, were involved. The instruments measured different situational variables at the end of the three didactic units: motivational climate, basic psychological needs, self-determined motivation and enjoyment. The results in the experimental unit, respect to control units, showed greater task climate, greater satisfaction of basic psychological needs, greater self-determined forms of motivation as well as greater enjoyment of the students. Therefore, the effectiveness of this intervention reflects the importance of the implementation of strategies related to TARGET areas in the physical education lessons to improve the task climate, so it influences student motivation and enjoyment of the students. Key words:teacher intervention; student motivation; basic psychological needs; enjoyment; physical education; TARGET areas.
The present viewpoint summarizes the major threats to the sustainability of marine food resources from an applied ecological and fishery approach. Threats include unsustainable activities related to fisheries, aquaculture, urban and tourism development, marine traffic, introduced and spread of non-native species, other human industrial actions, as well as climate change, invasive alien species, and inadequate policies and legislation. This contribution still aims to identify main key elements concerned in the sustainable use of these resources; six groups are identified: (1) identification of main exploited commercial species, differentiation from other similar resources, and normalization of their common names; (2) ecosystem-based management of coastal ocean waters; (3) biodiversity, taxonomic biogeography and oceanographic forces; (4) responsible fish consumption; (5) ''Mediterranean diet"; (6) fisheries biology studies, mainly with an ecosystem approach. A comparison between most-consumed native fishing products in Spanish Mediterranean and Canary Islands shows high similarity in seafood, putting in evidence the broad presence of the "Mediterranean diet" in both regions. This paper also aims to be a baseline to support and identify ongoing/further measures for conservation of associate biodiversity and main exploited commercial species. Some remarks on fisheries biology studies, as a useful tool for assessment, management and conservation of marine food resources are made; these are related to: regulations of fishing gear and fishing activity; assessments of their impact as well as of the commercial fish stocks potentiality; improvement of the statistical control of fish landings; marine protected areas; application of the ecosystem approach; and awareness of responsible fish consumption.
