El proyecto arranca de una idea central que consiste en programar todas las clases de inglés que correspondan a los dos ciclos de la ESO, partiendo de dos realidades culturales, como son: -la isla en la que vive el alumno con sus implicaciones en la región 'I shall show you my island'. -El lugar donde se habla la lengua, objeto de aprendizaje (inglés) 'You will show me your country'. El grupo de trabajo está compuesto por 19 docentes tanto de EGB como de bachillerato, y pertenecen a la isla de La Palma todos ellos. El objetivo general que se propone es lograr desarrollar las capacidades de los alumnos en los ámbitos cognitivos, afectivos y sociales tomando como base para su logro las vivencias que el medio en que se desarrollan les son consustanciales con su propia vida. Desde un principio se propuso llevar a cabo una unidad didáctica conectada al 'proyecto general', de tal manera que fuese coherente y siguiese una línea general y espiral con el resto de las once unidades restantes que forman en su conjunto todo el proyecto de enseñanza de la ESO. La unidad didáctica como un 'todo' organizado no se ha llevado a la práctica este curso, sin embargo a medida que se iba elaborando material, se iba investigando en el aula. Además de la aportación de la asesora de inglés, este trabajo se ha apoyado en: libros de texto, revistas pedagógicas, material de reprografía, medios informáticos, etc. En cuanto a la valoración del proyecto ha sido muy positiva tanto por el propio grupo de trabajo como por el público asistente a las Jornadas de Innovación celebradas en La Palma y donde pudo presentarse la experiencia..

This document examines, bases on the analysis of observable characteristics, if an income gapexists between the raizal population and non raizal population of San Andres Island. For thispurpose, the information of the SISBEN II survey for the year 2004, compelled by the NationalPlanning Department (DNP, Spanish acronym) is used. The methodological strategy uses quantileregressions to determine the existence of pay gaps throughout the distribution of income. Theresults suggest that being raizal has a negative impact on income for the lower quantiles. However,this difference vanishes as income increases, becoming positive at higher levels.

El autor hace un detallado recorrido por el mundo de los videojuegos desde los primeros modelos hasta la actualidad para darnos a conocer, entre otros, los videojuegos narrativos. Siendo la repetición una de las características típicas de los videojuegos, es através de ella que los niños pueden aprender bien en sentido positivo: superación del fracaso, perseverancia, etcétera; bien en sentido negativo: sexismo, capitalismo ambicioso, etcétera.

Forma parte de una serie de lectura para niños en doce niveles diferentes divididos en historias que todavía están relacionadas con las experiencias de los alumnos y, por tanto, despiertan el interés por la lectura. En ésta se trata de un pájaro mascota que un día se escapa de la jaula y sale volando por la ventana. Cada cuatro páginas hay juegos de palabras, crucigramas, verdadero-falso y preguntas de selección múltiple para reforzar la comprensión del texto. Cualquier palabra nueva se explica por una página en la foto diccionario.

Se estudian las características de estos animales, de los cuales viven aún hoy alrededor de ocho mil quinientas especies, y cuyo origen se remonta a muchos millones de años atrás, pues los fósiles encontrados de una especie de los dinosaurios, les relacionan con los antepasados de los pájaros actuales.

I examined lists of endangered species from northeastern and midwestern United States to assess the extent to which they were dominated by species considered rare due to their vulnerability to anthropogenic stressors or, instead, by species whose rarity might be explained otherwise. Northeastern states had longer species lists than midwestern states, and more species associated with locally rare prairie habitats. More species at the edge of their geographic range appeared on lists from the Northeast than the Midwest. About 70% of listed species overall have shown either no significant population trend, or increases, at the continental scale, but wetland and prairie species were frequently listed, consistent with the generally acknowledged, widespread loss of these habitats. Curiously, midwestern states tended to list fewer forest species, despite evidence that forest fragmentation there has had strongly deleterious effects on regional bird populations. Overall, species appear to be listed locally for a variety of reasons not necessarily related to their risk of extinction generally, potentially contributing to inefficient distributions of limited resources to deal effectively with species that legitimately require conservation attention. I advocate a continental perspective when listing species locally, and propose enhanced criteria for characterizing species as endangered at the local level.

Breeding seabirds are threatened by human activities that affect nesting and foraging habitat. In Canada, one of the seabirds most at risk of extirpation is the Roseate Tern, Sterna dougallii. Although critical nesting habitat has been identified for the Roseate Tern in Canada, its foraging locations and the diet of its chicks are unknown. Therefore, our goal was to determine the foraging locations and diet of chicks of Roseate Tern breeding on Country Island, Nova Scotia, which is one of Canada's two main breeding colonies. In 2003 and 2004, we radio-tracked the Roseate Tern by plane to locate foraging areas and conducted feeding watches to determine the diet of chicks. Roseate Tern foraged approximately 7 km from the breeding colony over shallow water < 5 m deep. In both years, sand lance, Ammodytes spp., was the most common prey item delivered to chicks, followed by hake, Urophycis spp. Our results are consistent with previous work at colonies in the northeastern United States, suggesting that throughout its range, this species may be restricted in both habitat use and prey selection. The reliance on a specific habitat type and narrow range of prey species makes the Roseate Tern generally susceptible to habitat perturbations and reductions in the availability of prey.

Roadside surveys such as the Breeding Bird Survey (BBS) are widely used to assess the relative abundance of bird populations. The accuracy of roadside surveys depends on the extent to which surveys from roads represent the entire region under study. We quantified roadside land cover sampling bias in Tennessee, USA, by comparing land cover proportions near roads to proportions of the surrounding region. Roadside surveys gave a biased estimate of patterns across the region because some land cover types were over- or underrepresented near roads. These biases changed over time, introducing varying levels of distortion into the data. We constructed simulated population trends for five bird species of management interest based on these measured roadside sampling biases and on field data on bird abundance. These simulations indicated that roadside surveys may give overly negative assessments of the population trends of early successional birds and of synanthropic birds, but not of late-successional birds. Because roadside surveys are the primary source of avian population trend information in North America, we conclude that these surveys should be corrected for roadside land cover sampling bias. In addition, current recommendations about the need to create more early successional habitat for birds may need reassessment in the light of the undersampling of this habitat by roads.

Digital map products that integrate long-term duck population and land-use data are currently being used to guide conservation program delivery on the Canadian Prairies. However, understanding the inter-relationships between ducks and other grassland bird species would greatly enhance program planning and delivery. We hypothesized that ducks, and Northern Pintail (Anas acuta) in particular, may function as an umbrella guild for the overall breeding habitat quality for other grassland bird species. We compared grassland bird species richness and relative abundance among areas of low, moderate, and high predicted waterfowl breeding densities (i.e., duck density strata) in the southern Missouri Coteau, Saskatchewan. We conducted roadside point counts and delineated habitats within a 400 m radius of each point. The duck high-density stratum supported greater avian species richness and abundance than did the duck low-density stratum. Overall, duck and other grassland bird species richness and abundance were moderately correlated, with all r between 0.37 and 0.69 (all P < 0.05). Although the habitat requirements of Northern Pintail may overlap with those of other grassland endemics, priority grassland bird species richness was only moderately correlated with total pintail abundance in both years, and the abundances of pintail and grassland songbirds listed by the Committee on the Status of Endangered Wildlife in Canada were not correlated. No differences in the mean number of priority grassland species were detected among the strata. Adequate critical habitat for several priority species may not be protected if conservation is focused only in areas of moderate to high wetland density because large tracts of contiguous, dry grassland habitat (e.g., pasture) occur infrequently in high-quality duck habitat.
