The transition from kindergarten to primary: Methodological trategies

El presente trabajo está basado la experiencia que como docente he llevado a cabo en la etapa de educación infantil en dos centros educativos de la provincia de Toledo. En uno de ellos me encuentro actualmente siendo coordinadora de Educación Infantil y a su vez tutora en una clase del primer curso. El principal objetivo que pretendo llevar a cabo en dicha práctica consiste en: “Identificar las estrategias metodológicas que se llevan a cabo en dichos colegios para que el cambio del alumnado de etapa de infantil a primaria tenga lugar de manera ordenada, progresiva y secuenciada”. En primer lugar, se analizan diferentes contribuciones teóricas relacionadas con el cambio de la etapa de infantil a primaria y se presentan las diferencias organizativas, metodológicas y sociales que existen entre etapas Seguidamente, se explican las experiencias didácticas que se llevan a cabo para favorecer el tránsito en los centros estudiados en relación con docentes, familias y alumnadoThe present work is based on the experience that as a teacher I have carried out in the stage of early childhood education in two educational centers of the province of Toledo. In one of them, I am currently the Coordinator of Early Childhood Education and also a tutor in a class of the first course. The aim objective that I intend to carry out in this practice is "Identifying the methodological strategies that are carried out in these schools in order to carry out the change of stage from pre-primary to primary in a tidy, progressive and sequenced way". Firstly, the different theoretical contributions related to the change of stages are analyzed and the differences that exist between stages are presented. Next, the experiences that are carried out to work out well the transit in the studied centers in relation to teachers, families and students are explaine

Physico-chemical characterization of remains from a Bronze Age ochre-burial in Biniadris Cave (Menorca, Spain)

Red ochre pigments have been used since ancient times by many different civilisations on different continents. In the paper presented herein, ten manufactured artefacts and biological materials stained with a red pigment found in the Bronze Age burial site of Biniadris Cave (Menorca, Spain) have been characterised throught X-ray fluorescence, X-ray diffraction, Raman and infrared spectroscopy techniques, scanning electron microscopy and energy-dispersive X-ray spectroscopy. The surface analysis of the bones, hairs and ornaments allowed the chemical composition of the pigment used in the funeral practices and rituals to be unequivocally established as hematite-rich ochre. The finding of a gypsum preparation layer on a sample, below the ochre layer, suggests that it could have been used as a primer before sprinkling with hematite ochre. Given the excellent degree of conservation and the worth of this archaeological record for the study of the symbolic practices in the island of Menorca, these results call for further analyses on a larger set of archaeological artefacts to gain insight into the funeral practices conducted in this cave

Desarrollo de un panel fotovoltaico específico para un vehículo eléctrico ultraligero enfocado a la movilidad urbana

En la actualidad, los vehículos eléctricos son considerados como la mejor alternativa para la consecución de una movilidad urbana sostenible. No obstante, su implantación a gran escala está supeditada a la instalación de un número suficiente de estaciones de recarga y a un rediseño de la red de distribución de corriente eléctrica. Además de esto, el modelo de automóvil que domina el mercado actual, ya sea eléctrico o de combustión interna, se caracteriza por tener un peso diez veces superior al de la carga útil (personas más equipaje) que suele transportar, por lo que es muy poco eficiente en el uso de la energía. En este artículo proponemos un vehículo eléctrico ultraligero dotado de su propio generador fotovoltaico como prototipo de vehículo adecuado para conseguir una movilidad urbana sostenible. Este tipo de vehículos no necesitan de una amplia red de estaciones de recarga, por lo que su implantación a gran escala es mucho menos compleja. Para verificar la propuesta, se ha diseñado, construido y evaluado un panel fotovoltaico específico para este tipo de vehículos que alcanza una potencia específica de 27,24 W/kg en condiciones estándar, valor muy superior a la de los paneles fotovoltaicos comerciales. Se ha realizado un estudio experimental en el túnel de viento con el objetivo de conocer la influencia del generador fotovoltaico en el coeficiente aerodinámico del vehículo y de esta forma poder calcular las prestaciones del vehículo en un entorno urbano. Los resultados más importantes son que el vehículo, en condiciones estándar de irradiancia, puede circular a una velocidad máxima de 35 km/h sin necesidad de recargar energía de la red eléctrica. En estas mismas condiciones, si el vehículo circula a la máxima velocidad permitida en ciudad, 50 km/h, alcanzaría una autonomía de 200 km por cada kWh de energía recargado de la red eléctrica.Universidad de Málaga.

C-Pen Exam Reader and Reading in Basic Education : Will it be a good partnership?

There is an increasing number of students in basic education schools with difficulties in reading, and consequently, in writing. Our exploratory study aims to understand if the C Pen Exam Reader (C-Pen) helps in the learning process of students with language and writing difficulties. The methodology chosen was interviews with elementary school teachers, no special education teachers, and a speech therapist, as well as the support of CRTICee of the Amato Lusitano School Grouping. Thus, it was possible to assess the added value for students, not only in terms of their autonomy, since it is a reading pen, but also their self-esteem and inclusion in the school environment. It was also possible to clarify which points to improve in the use of this instrument to maximize its effectiveness and, thus, improve the quality of life of these students, such as prosody (accentuation, intonation, duration, rhythm of words and phrases).info:eu-repo/semantics/publishedVersio

A specific photovoltaic panel for an ultra-light electric vehicle focused on urban mobility

Nowadays, electric vehicles are considered the best alternative to achieve sustainable urban mobility. However, the extended implementation is conditional to a sufficient number of charging stations and the design of a new power grid distribution. Indeed, the vehicle model that dominates the current market, electric or thermal motors, is ten times heavier than its useful weight (occupant plus luggage), so it is not efficient in the way it uses the energy. In this article, an ultra-light electric vehicle with his own photovoltaic generator is proposed as an adequate vehicle prototype for sustainable mobility. This kind of vehicle does not need many charging stations and, because of that, the implantation is less complex than for other commercial vehicles. To verify this proposal, a specific photovoltaic panel was designed, manufactured and evaluated for this kind of vehicles. It can reach a specific power of 27.24 W/kg in STC, higher than commercial solar panels. An experimental study in a wind tunnel was conducted in order to know the influence of the photovoltaic generator in the drag coefficient, and to calculate the performance of the vehicle in an urban circuit. The most important results are that the vehicle, at STC, can circulate at a maximum speed of 35 km/h, without the need to charge the battery from the grid. For the same conditions, if the vehicle circulates at the maximum speed allowed in urban circuits, 50 km/h, it would have a range of 200 km per kWh charged from the grid.Universidad de Málaga.

The boson peak in structural and orientational glasses of simple alcohols: Specific heat at low temperatures

We review in this work specific-heat experiments, that we have conducted on different hydrogen-bonded glasses during last years. Specifically, we have measured the low-temperature specific heat Cp for a set of glassy alcohols: normal and fully-deuterated ethanol, 1- and 2- propanol, and glycerol. Ethanol exhibits a very interesting polymorphism presenting three different solid phases at low temperature: a fully-ordered (monoclinic) crystal, an orientationally-disordered (cubic) crystal or 'orientational glass', and the ordinary structural glass. By measuring and comparing the low-temperature specific heat of the three phases, in the 'boson peak' range 2-10 K as well as in the tunneling-states range below 1K, we are able to provide a quantitative confirmation that ''glassy behavior'' is not an exclusive property of amorphous solids. On the other hand, propanol is the simplest monoalcohol with two different stereoisomers (1- and 2-propanol), what allows us to study directly the influence of the spatial rearrangement of atoms on the universal properties of glasses. We have measured the specific heat of both isomers, finding a noteworthy quantitative difference between them. Finally, low-temperature specific-heat data of glassy glycerol have also been obtained. Here we propose a simple method based upon the soft-potential model to analyze low-temperature specific-heat measurements, and we use this method for a quantitative comparison of all these data of glassy alcohols and as a stringent test of several universal correlations and scaling laws suggested in the literature. In particular, we find that the interstitialcy model for the boson peak [A. V. Granato, Phys. Rev. Lett. 68 (1992) 974] gives a very good account of the temperature at which the maximum in Cp/T^3 occurs.Comment: 16 pages, 2 figures, Proceedings of the 4th International Discussion Meeting on Relaxations in Complex Systems, Hersonissos (Crete), June 2001.
