Jocs d'estratègia i el currículum escolar

L'enfocament competencial de l'ensenyament de les matemàtiques obre un nou espai per a la utilització didàctica dels jocs d'estratègia, que poden contribuir al desenvolupament de les quatre dimensions indicades en els documents del Departament d'Ensenyament de la Generalitat de Catalunya: Resolució de problemes, Raonament i Prova, Connexions i Comunicació, i Representació. Els jocs d'estratègia responen també al repte de treballar materials que estiguin a l'abast de tota mena d'alumnat i de permetre que cadascú pugui construir-se un recorregut d'aprenentatge coherent amb els seus interessos i la seva capacitat. Partint de tres exemples (Torres d'Hanoi, Granotes i Gripaus i Joc de les Fitxes), l'article analitza també les matemàtiques que estan amagades a sota d'un apropament lúdic i aparentment senzill. Pensem que és interessant donar a professorat i alumnat ocasions per a profunditzar autònomament els continguts i descobrir el plaer de la investigació.The competence approach to teaching mathematics opens up a new space for the educational use of strategy games. They can contribute to the development of the four dimensions mentioned in documents from the Department of Education of the Generalitat de Catalunya: Problem Solving, Reasoning and Proof, Connections and Communication, and Representation. Strategy games respond to the challenge of providing activities within any students reach. They also offer an opportunity to build a learning path tailored to their own interests and abilities. Furthermore, through three games (Hanoi Towers, Frogs and Toads, and Form and Value), the article examines the mathematics hidden under a deceptively simple and fun approach. We think it is interesting to give teachers and students the opportunity to go more deeply into the content and autonomously discover the pleasure of research

La educación no reglada vuelve a clase:proyectos conjuntos entre museos y escuelas para mejorar el aprendizaje

Desde ámbitos diferentes se está abriendo una interesante discusión sobre cómo hacer más efectiva y constante la colaboración entre instituciones, en términos generales i en relación con las matemáticas. Cuando empezó, el objetivo de nuestro museo (MMACA – Museu de Matemàtiques de Catalunya) era “ayudar a las escuelas a mejorar el aprendizaje de las matemáticas, desde el ámbito de la educación no reglada”. La temática del non-formal learning - cuyas características analizaremos- está ahora muy presente en los debates educativos, como demuestran los dos proyectos que son objeto de esta comunicación: La Comunidad de Prácticas “Patrimoni i Escola”, promovida este año por la Agència Catalana del Patrimoni Cultural, a la luz del interés suscitado por las dos conferencias sobre buenas prácticas de colaboración entre museos y escuelas que la misma agencia ha organizado. El proyecto Erasmus+ “Mathspaces. A non-formal approach to mathematics”, en lo que participamos juntos con la Maison des Maths (Bélgica) –coordinador; Il Giardino d’Archimede (Italia); Fermat Science (Francia), Imaginary (Alemania). Objetivo del proyecto es crear conjuntamente dos pequeñas exposiciones, una guía y un manual de soporte que sirvan de puente entre escuelas y museos para ofrecer una imagen positiva de las matemáticas y mejorar su aprendizaje

Habitat use during post-pre-breeding period in a Rock Sparrow <em>Petronia petronia</em> population

Most studies focusing on Rock Sparrow populations concern their breeding biology. With this study, we aim to investigate the wintering habitat and social behaviour outside the breeding period. In the study area the species is present all year long, and, outside the breeding period, birds frequently gather together on flocks of different size (3-150 individuals), which are larger in the coldest months. The habitat types most used by the species were cereal fields with crops in their first stage of development (17.71% ± 4.72 Standard Deviation) and arable stubbles, both of them with bushes and trees on their boundaries (82.4%), which likely provide shelters from predators. The bird species most frequently associated with Rock Sparrow flocks were Tree Sparrow, Starling and Crested Lark. Holes in the roof tiles of the same abandoned buildings used for breeding were also used as night shelters. The average hours of leaving and returning to the shelters was strictly related to the photoperiod (rs = -0.9405; 0.8810)

Mini-curso del aula a una exposición: ida y vuelta

Los primeros módulos realizados para las exposiciones itinerantes del MMACA eran deudores de nuestras experiencias como docentes. Discutimos dos años cómo adaptar estos materiales, convencidos de que el aprendizaje de nuestros alumnos (significativo, duradero, competencial) empezaba por sus manos. En estos años en el museo, hemos desarrollado un modelo propio de educación no formal, siempre buscando cómo colaborar con las escuelas para mejorar el aprendizaje del alumnado. Ahora estamos diseñando una exposición que se puede montar en un colegio, con pocos medios y materiales baratos, en un formato adapto para el aula. En el mini-curso ofreceremos actividades que discutiremos y/o experimentaremos directamente, para que nos ayuden a compartir unas ideas que pensamos interesantes: (1) La educación no formal: un aprendizaje diferente y complementario; (2) Las modalidades, contenidos, tiempos, dinámicas, interacciones, información, intuición…; (3) Accesibilidad y competencias; (4) Materiales y actividades para una exposición, una feria, un taller en la exposición y el aula (o un taller escolar): cómo relacionar, aprovechar y adecuar las experiencias;(5) Hands-on, Minds-on, hearts-on: construir objetos, conceptos y emociones. Muchos de estos materiales se verán como módulos en la mini-exposición que presentamos en estas mismas JAEM

The red-billed leiothrix (Leiothrix lutea): a new invasive species for Britain?

Invasive non-native species (INNS) are one of the major threats to global biodiversity. Climate change and garden bird-feeding may facilitate the establishment of INNS. The Red-billed Leiothrix Leiothrix lutea is a small woodland passerine, native to subtropical Asia, that is an INNS in several parts of the world, including Europe, following escapes from the aviculture trade. Recently, populations of Red-billed Leiothrix have established in Spain, Portugal, Italy and France. Previous studies have shown that much of Europe is suitable for the species, including southern Britain. The Red-billed Leiothrix has not previously been considered as at high risk of establishment in Britain, but we document recent records, including a cluster in southern England, suggesting that establishment may already be underway. We discuss the potential negative impacts of this invasive species on local ecosystems, and how a warming climate and garden bird-feeding might assist their establishment in temperate Europe. We also highlight the importance of improved recording to monitor the potential establishment of INNS, such as the Red-billed Leiothrix, in Britain

Experimental nest cooling reveals dramatic effects of heatwaves on reproduction in a Mediterranean bird of prey

Future climatic scenarios forecast increases in average temperatures as well as in the frequency, duration, and intensity of extreme events, such as heatwaves. Whereas behavioral adjustments can buffer direct physiological and fitness costs of exposure to excessive temperature in wild animals, these may prove more difficult during specific life stages when vagility is reduced (e.g., early developmental stages). By means of a nest cooling experiment, we tested the effects of extreme temperatures on different stages of reproduction in a cavity-nesting Mediterranean bird of prey, the lesser kestrel (Falco naumanni), facing a recent increase in the frequency of heatwaves during its breeding season. Nest temperature in a group of nest boxes placed on roof terraces was reduced by shading them from direct sunlight in 2 consecutive years (2021 and 2022). We then compared hatching failure, mortality, and nestling morphology between shaded and non-shaded (control) nest boxes. Nest temperature in control nest boxes was on average 3.9 degrees C higher than in shaded ones during heatwaves, that is, spells of extreme air temperature (>37 degrees C for =2 consecutive days) which hit the study area during the nestling-rearing phase in both years. Hatching failure markedly increased with increasing nest temperature, rising above 50% when maximum nest temperatures exceeded 44 degrees C. Nestlings from control nest boxes showed higher mortality during heatwaves (55% vs. 10% in shaded nest boxes) and those that survived further showed impaired morphological growth (body mass and skeletal size). Hence, heatwaves occurring during the breeding period can have both strong lethal and sublethal impacts on different components of avian reproduction, from egg hatching to nestling growth. More broadly, these findings suggest that the projected future increases of summer temperatures and heatwave frequency in the Mediterranean basin and elsewhere in temperate areas may threaten the local persistence of even relatively warm-adapted species
