 The improvements carried out in the last decades in the field of Information and the Communication Technologies are significantly perceived in the educational institutions. Besides the well-known advantages from an instrumental, administrative or managerial point of view, we assist to unprecedented extension of new possibilities of social interaction as well as to the creation of new learning contexts. Thus, this work is aimed at analysing the benefits that technology can provide in the students’ learning process, making special emphasis not only on the potential of these resources to favour students’ autonomy and responsibility in the teaching-learning process, but also on their possibilities for the development of intercultural competences. Among the conclusions, we mainly stand out two issues: on the one hand, the urgency to improve teachers’ preparation, to make the most of the pedagogical potential of the digital resources and, on the other hand, the need to deepen in the knowledge of the effects that, on a long-term basis, may involve the use of digital technologies in our students’ way of behaving and of mixing with each  other.
Aprendizaje cooperativo: práctica pedagógica para el desarrollo escolar y cultural
Si alguna coincidencia hay en la literatura sobre desarrollo escolar y cultural en las escuelas de educacion primaria y secundaria, es la conveniencia de usar tecnicas de aprendizaje cooperativo. Tal consenso ha puesto de relieve la necesidad de una formacion del profesorado basada en estrategias de aprendizaje cooperativo. El estudio trata sobre los efectos de la tecnica Jigsaw de Eliot Aronson en un grupo de profesores (N = 6) en aulas con heterogeneidad etnica y cultural. Utilizamos un diseno cuasi-experimental de dos grupos con pretest y postest. Los resultados avalan la utilidad de su incorporacion a la formacion inicial y continua de los profesores, teniendo en cuenta las ventajas informadas en el curso de la experiencia.
17 &mgr;m pixel 640 x 480 microbolometer FPA development at BAE Systems
BAE Systems has developed an advanced 640 x 480 focal plane array (FPA) with a 17 &mgr;m pixel pitch. Sensitivity of ≤ 50 mK was demonstrated and the FPAs were used in imaging demonstrations. Successful scaling of BAE Systems' patented single contact per pixel, single-level microbolometer process to 17 &mgr;m pitch provides a path toward next generation microbolometer imaging systems.
