Proposta 2.0 d’incorporació real de les TIC al currículum

Per tal que la incorporació de les TIC a l’ensenyament fóra real, el docent hauria de saber, en primer lloc, què ha d’ensenyar (per tal de poder educar en TIC) i, en segon lloc, com ho ha d’ensenyar (per tal de poder educar amb TIC). Pel que fa al primer punt, és la llei que l’ha d’aclarir i, pel que fa al segon punt, cal que el docent adquirisca/assage noves metodologies. L’article que presentem revisa la legislació vigent sobre la integració de les TIC a les aules de primària i de secundària. Així mateix, presenta els resultats d’una enquesta a professorat i alumnat la finalitat de la qual és esbrinar el grau de coneixement que tenen aquests col·lectius de les TIC i l’ús que en fan.For the incorporation of ICT in education to be real, the teacher should know, first, what should be taught (in order to educate ICT) and, secondly, how it should be taught (to be able to teach by means of ICT). Regarding the first point, the law should be the one to clarify it and, as regards the second point, the teacher must acquire/assage new methodologies. Likewise, the article presents the results of a survey to teachers and students the purpose of which is to know the degree of knowledge of ICT that these collective have and the use that do

How efficient is an integrative approach in archaeological geophysics? Comparative case studies from Neolithic settlements in Thessaly (Central Greece)

The geophysical prospection of Neolithic tells imposes specific challenges due to the preservation and nature of the architectural context and the multiple, usually disturbed, soil strata. Contrary to the usual application of a single method, this paper deals with the advantages of using an integrated geophysical approach through the employment of various methodologies to map the Neolithic cul-tural and environmental landscape of Thessalian tells (magoules) in Central Greece. The success and failure of each method in resolving the various features of the magoules are discussed in detail, and as a whole, they demonstrate the benefits of a manifold geophysical prospection of the sites

Effect of surfactant concentration on the responsiveness of a thermoresponsive copolymer/surfactant mixture with potential application on Smart foams formulations

We studied a system formed by a mixture of a thermoresponsive negatively charged graft copolymer (Alg-g-PNIPAAm) with a brush-type structure, and an oppositely charged surfactant (DTAB), in bulk and at the air-solution interface. We performed experiments of surface tension, electrophoretic mobility, dynamic and static light scattering and atomic force microscopy in order to characterize the complexes formed as a function of DTAB concentration and temperature. We found that these polymer-surfactant complexes are able to respond by changing their sizes, both in bulk and at the air-solution interface, when T is increased above the coil-globule transition temperature (LSCT) of the copolymer. However, the thermoresponse was found to be dependent on surfactant concentration, cs: for cs < 2.8 mM, the size of the aggregates decreases as T increases but, for cs >= 2.8 mM, the opposite behavior takes place, i.e. the size increases with T. At the interface, the intensity of the effect produced on the surface tension by increasing T above LCST diminishes continuously as cs increases, reducing the ability of the interfacial complex to respond to temperature changes. We studied the stability of aqueous foams formulated with these mixtures as a function of T and cs. We found that the stability of the foam can be modulated by changing T, but we observed that this effect is dependent on the surfactant concentration range. We found a correlation between changes in the aggregates sizes, the surface tension behavior and the responsiveness of foam stability to changes of temperature
