Dins el bosc de la cultura visual. Apunts per a una actualització pedagògica

L'era de la comunicació acara la comunitat educativa davant de nous reptes, especialment en l'àmbit de la cultura visual. La cultura visual es manifesta avui arreu i no hi ha àmbit ni familiar ni social ni educatiu que no en participi. Més enllà de la visualització i experimentació d'alguns procediments artístics canònics, l'ensenyament de les arts visuals i plàstiques observa la necessitat d'ampliar el seu radi d'acció, reflexió i anàlisi de manera coparticipada. Un repàs a la trajectòria històrica de l'aprenentatge artístic dóna peu a algunes preguntes rellevants com ara, quins aprenentatges per a quines competències? Per a quina societat i amb quins instruments cal educar els infants? Quines inèrcies i teories s¿hereten del passat i quin lloc cal que tinguin en el futur? Quines aportacions cognitives o empíriques permetrien una renovació positiva en l'àmbit de l¿educació visual i plàstica? Són preguntes difícils però peremptòries si no es vol girar l'esquena a l'evidència dels canvis comunicatius i socials del nostre temps.

La adquisición de las competencies de autoregulación. Análisis de su concepción y aprendizaje en diferentes estudios universitarios.

Es presenta una recerca sobre la competència d'autoregulació de l'aprenentatge d'estudiants universitaris. Des d'una perspectiva socio-constructivista i d'acord amb les fases d'adquisició de l'autoregulació proposades per Zimmerman (2000), s'analitzen les seves dimensions i, específicament, la planificació de l'aprenentatge individual i de grup. Es van analitzar quatre propostes d'innovació docent sobre l'ensenyament de l'autoregulació. Van participar 9 professors i 386 alumnes de la Universitat de Barcelona, pertanyents a tres estudis (Biologia, Formació del Professorat i Psicologia) i que cursaven quatre assignatures diferents durant el curs acadèmic 2007-2008. Els resultats, en el seu conjunt, mostren que els estudiants: entenen la planificació com una activitat formal ubicada exclusivament a l' inici del procés d'aprenentatge; redueixen la seva funció a l'organització del treball, i no relacionen el seu ús amb la gestió, individual i de grup, dels esforços dirigits a construir coneixement.

Reproducibility of species lists, visual cover estimates and frequency methods for recording high mountain vegetation

Question: When multiple observers record the same spatial units of alpine vegetation, how much variation is there in the records and what are the consequences of this variation for monitoring schemes to detect change? Location: One test summit in Switzerland (Alps) and one test summit in Scotland (Cairngorm Mountains). Method: Eight observers used the GLORIA protocols for species composition and visual cover estimates in percent on large summit sections (>100 m2) and species composition and frequency in nested quadrats (1 m2). Results: The multiple records from the same spatial unit for species composition and species cover showed considerable variation in the two countries. Estimates of pseudoturnover of composition and coefficients of variation of cover estimates for vascular plant species in 1m x 1m quadrats showed less variation than in previously published reports whereas our results in larger sections were broadly in line with previous reports. In Scotland, estimates for bryophytes and lichens were more variable than for vascular plants. Conclusions: Statistical power calculations indicated that, unless large numbers of plots were used, changes in cover or frequency were only likely to be detected for abundant species (exceeding 10% cover) or if relative changes were large (50% or more). Lower variation could be reached with the point methods and with larger numbers of small plots. However, as summits often strongly differ from each other, supplementary summits cannot be considered as a way of increasing statistical power without introducing a supplementary component of variance into the analysis and hence the power calculations.

En torno a los efectos de la edad en el aprendizaje escolar de una lengua extrangera

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.

El portafolio o la carpeta de aprendizaje en enfermería como instrumento para un aprendizaje reflexivo y crítico: Una experiencia exportable a otras disciplinas

La experiencia que se presenta se desarrolla en la Escuela de Enfermería y Podología de la Universidad de Barcelona. Desde el 2003 y hasta la actualidad, organizo la asignatura de fundamentos de enfermería con portafolio o carpeta de aprendizaje (CA) en un grupo de docencia de enfermería, la asignatura es troncal, de primer semestre y se le asignan 13,5 créditos. La mejora docente viene dada por la creencia que el cambio en la evaluación, entendida como esencial en el modelo de enseñanza, comporta un cambio en el aprendizaje así como en su percepción y en las relaciones que se establecen en el aula. Es así como se pretende pasar de un paradigma docente estándar a uno de reflexivo y crítico. En el artículo se sitúa la asignatura en la enseñanza, se hace una argumentación teórica del por qué del cambio para la mejora docente y la elección de la CA, se describe la organización de la asignatura con CA y las características, para terminar se lleva a cabo un análisis reflexivo de las ventajas y las dificultades que comporta un cambio aislado en una institución tradicional.
