La evolución del pensamiento ha sido causada por los diversos medios de comunicación: el diálogo en la Grecia clásica o la imprenta en el Renacimiento. Con la revolución técnica en la que se basan los medios actuales, estamos asistiendo a un nuevo cambio de necesaria inclusión en la enseñanza: ya no basta con la enseñanza de la lengua oral y escrita, ahora se impone la enseñanza del medio audiovisual. Opina la autora de este artículo que la LOGSE no ha respondido a las expectativas que sobre este ámbito se habían creado porque no se dota a los centros del material necesario ni a los profesores de la adecuada preparación

The purpose of this article is to treat a currently much debated issue, the effects of age on second language learning. To do so, we contrast data collected by our research team from over one thousand seven hundred young and adult learners with four popular beliefs or generalizations, which, while deeply rooted in this society, are not always corroborated by our data.Two of these generalizations about Second Language Acquisition (languages spoken in the social context) seem to be widely accepted: a) older children, adolescents and adults are quicker and more efficient at the first stages of learning than are younger learners; b) in a natural context children with an early start are more liable to attain higher levels of proficiency. However, in the context of Foreign Language Acquisition, the context in which we collect the data, this second generalization is difficult to verify due to the low number of instructional hours (a maximum of some 800 hours) and the lower levels of language exposure time provided. The design of our research project has allowed us to study differences observed with respect to the age of onset (ranging from 2 to 18+), but in this article we focus on students who began English instruction at the age of 8 (LOGSE Educational System) and those who began at the age of 11 (EGB). We have collected data from both groups after a period of 200 (Time 1) and 416 instructional hours (Time 2), and we are currently collecting data after a period of 726 instructional hours (Time 3). We have designed and administered a variety of tests: tests on English production and reception, both oral and written, and within both academic and communicative oriented approaches, on the learners' L1 (Spanish and Catalan), as well as a questionnaire eliciting personal and sociolinguistic information. The questions we address and the relevant empirical evidence are as follows: 1. "For young children, learning languages is a game. They enjoy it more than adults."Our data demonstrate that the situation is not quite so. Firstly, both at the levels of Primary and Secondary education (ranging from 70.5% in 11-year-olds to 89% in 14-year-olds) students have a positive attitude towards learning English. Secondly, there is a difference between the two groups with respect to the factors they cite as responsible for their motivation to learn English: the younger students cite intrinsic factors, such as the games they play, the methodology used and the teacher, whereas the older students cite extrinsic factors, such as the role of their knowledge of English in the achievement of their future professional goals. 2 ."Young children have more resources to learn languages." Here our data suggest just the opposite. The ability to employ learning strategies (actions or steps used) increases with age. Older learners' strategies are more varied and cognitively more complex. In contrast, younger learners depend more on their interlocutor and external resources and therefore have a lower level of autonomy in their learning. 3. "Young children don't talk much but understand a lot"This third generalization does seem to be confirmed, at least to a certain extent, by our data in relation to the analysis of differences due to the age factor and productive use of the target language. As seen above, the comparably slower progress of the younger learners is confirmed. Our analysis of interpersonal receptive abilities demonstrates as well the advantage of the older learners. Nevertheless, with respect to passive receptive activities (for example, simple recognition of words or sentences) no great differences are observed. Statistical analyses suggest that in this test, in contrast to the others analyzed, the dominance of the subjects' L1s (reflecting a cognitive capacity that grows with age) has no significant influence on the learning process. 4. "The sooner they begin, the better their results will be in written language"This is not either completely confirmed in our research. First of all, we perceive that certain compensatory strategies disappear only with age, but not with the number of instructional hours. Secondly, given an identical number of instructional hours, the older subjects obtain better results. With respect to our analysis of data from subjects of the same age (12 years old) but with a different number of instructional hours (200 and 416 respectively, as they began at the ages of 11 and 8), we observe that those who began earlier excel only in the area of lexical fluency. In conclusion, the superior rate of older learners appears to be due to their higher level of cognitive development, a factor which allows them to benefit more from formal or explicit instruction in the school context. Younger learners, however, do not benefit from the quantity and quality of linguistic exposure typical of a natural acquisition context in which they would be allowed to make use of implicit learning abilities. It seems clear, then, that the initiative in this country to begin foreign language instruction earlier will have positive effects only if it occurs in combination with either higher levels of exposure time to the foreign language, or, alternatively, with its use as the language of instruction in other areas of the curriculum.

Este artículo propone el enfoque contextual como nuevo marco de estudio de las inundaciones históricas. El enfoque contextual tiene su origen en la reflexión geográfica sobre los riesgos naturales iniciada en la escuela geográfica norteamericana hace ya más de medio siglo y pone especial énfasis en la dimensión humana de estos fenómenos definida geográfica e históricamente, sin olvidar los aspectos físicos de las inundaciones en el territorio objeto de estudio. En una primera parte del presente artículo se describen los niveles de análisis y componentes que componen el estudio de las inundaciones histórica5 desde el enfoque contextual. La segunda parte es una aplicación del enfoque contextual al caso de la ciudad de Girona

La Fantasia Il·lustrada és un treball d’investigació entorn la fantasia lliure, gènere compositiu de la segona meitat del segle XVIII. Aprofundeix, a partir d’un extens buidatge bibliogràfic, en els coneixements sobre aquest gènere oblidat, ubicant-lo en el seu entorn musical i social, i reconeix l’empremta que va deixar en l’estètica d’aquells anys, la qual justifica la seva vàlua i el clam per reivindicar el reconeixement que es mereix. Per tal d’aconseguir aquest fi, aquest treball elabora sobre les diferents realitats estètiques de meitat de segle, sobre l’art de la jardineria, sobre Carl Philipp Emanuel Bach, i sobre la pràctica improvisativa.

Darrerament hem investigat l’emergència del metallenguatge en els infants en contextos d’interaccions comunicatives naturals (Ivern, 2006) i hem establert un sistema de categories metalingüístiques per tal d’identifi car i conceptualitzar aquells comportaments relacionats amb la refl exió sobre el llenguatge, tot emmarcat en una perspectiva evolutiva. Els participants han estat 32 infants, 16 nens i 16 nenes, d’edats compreses entre els 2 anys i 8 mesos i els 8 anys, tots ells de parla castellana. Entre altres aspectes hem analitzat les funcions que compleix, atenent especialment a la relació tripartida entre metallenguatge, metacognició i recursivitat. En darrer terme, ens ha semblat interessant analitzar la relació del metallenguatge amb la teoria de la ment i el sentit de l’humor. La naturalesa metalingüística de l’humor ha estat estudiada des de principis dels anys setanta (Shultz, 1974 i Cazden, 1976) fi ns l’actualitat (Puche, 2001; Puche i Lozano, 2002). Bona part de l’nterès que ha desvetllat és per la seva importància com a indicador de l’activitat cognitiva. A continuació exposem una refl exió breu sobre el paper que juga el sentit de l’humor en els infants des de la perspectiva de la psicologia cognitiva.

L a denominació Educació Física pot confondre la ciutadania respecte dels veritables objectius psicopedagògics, orgànics i socioculturals del comportament motor humà en l’educació integral de la persona. La manca de valoració social de la matèria converteix la recerca del prestigi en una lluita contínua contra la resta de disciplines científi ques acceptades culturalment, i es tradueix en múltiples situacions: l’utilitarisme dels seus coneixements, el reconeixement social o el volum de dedicació horària a la matèria. En- front d’aquesta casuística, des d’un enfocament de camp de la psique humana, es defensa que l’Educació Física és també educació intel·lectual. Així es comprèn que l’Educació Física no és una activitat que realitza un subjecte com a manifestació d’alguna facultat interna o cognoscitiva que li ho permet. Educar-se en la motricitat quotidiana i esportiva signifi ca, per a l’ésser humà, construir-se psicològicament com a tal persona diferenciada. Aquest plantejament naturalista de la intelligència permet identifi car el caràcter multidimensional d’aquesta, que, en primer lloc i en un sentit ampli del concepte, invita a plantejar la conveniència del cognom de l’Educació: «Física». I, en segon lloc, des d’un sentit restringit, ajuda a comprendre que el comportament motor humà és educació intel·lectual que fon la sensorialitat propioceptiva i esquelètica amb la temporalitat com a criteri d’èxit: l’alumne, l’atleta o el jugador intel·ligent que realitza els moviments en el moment oportú, independentment del nivell funcional rígid o canviant del comportament motor o esportiu a ensenyar. Aquest plantejament teòric pretén superar la incertesa de l’edifi ci acadèmic de l’Educació Física per bastir-lo en una futura comprensió antropològica i humanista de la intel·ligència i del moviment: ... «La carrera del hombre no es la carrera de un animal con una inteligencia humana sobreañadida, sino que es una nueva forma de correr, la del hombre, no sólo diferenciada por su específi ca contextura corporal y su particular locomoción , sino en cuanto que es un ser inteligente que corre: la propia carrera es inteligencia.» (Cagigal, 1986, p.17).

El principal objectiu d’aquest projecte és aconseguir classificar diferents vídeos d’esports segons la seva categoria. Els cercadors de text creen un vocabulari segons el significat de les diferents paraules per tal de poder identificar un document. En aquest projecte es va fer el mateix però mitjançant paraules visuals. Per exemple, es van intentar englobar com a una única paraula les diferents rodes que apareixien en els cotxes de rally. A partir de la freqüència amb què apareixien les paraules dels diferents grups dins d’una imatge vàrem crear histogrames de vocabulari que ens permetien tenir una descripció de la imatge. Per classificar un vídeo es van utilitzar els histogrames que descrivien els seus fotogrames. Com que cada histograma es podia considerar un vector de valors enters vàrem optar per utilitzar una màquina classificadora de vectors: una Support vector machine o SVM

El febrer de 2001 moria a Santa Cristina d’Aro Jordi Verrié i Faget, personatge polifacètic que al llarg de la seva vida s’havia dedicat a diferents tasques sempre en defensa i reconeixement de la cultura i la pedagogia catalanes. Investigador incansable, ens deixava un important llegat fruit de la seva passió pels llibres i del seu interès per la nostra història educativa, una part del qual era donat a la Universitat de Girona. Aquest fons documental és el punt de partida d’aquest estudi, que vol aprofundir en la figura de Verrié, contextualitzar el seu fons i valorar què significa per la nostra pedagogia. Aquest és un reconeixement a Jordi Verrié i a la seva tasca, que representa una important aportació a la història de l’educació catalana
