Coherencias cognitivas vs matemáticas en el estudio del cambio

Se indaga en los desplazamientos entre herramientas de comunicación que ponen en juego profesores a la hora de comunicar qué y cómo cambia en una situación, en el marco de una línea de investigación en Pensamiento y Lenguaje Variacional (Proyecto Fondecyt Nº1030413 y Proyecto Diumce 06/07). Adscribimos a una mirada sistémica en la que entendemos a las matemáticas como una actividad humana en donde cobra vital importancia la persona haciendo matemáticas y no sólo el producto matemático. Por ello resulta relevante considerar -en la praxis educativa- las negociaciones y búsqueda de consenso entrelazadas éstas, con las acciones cognitivas de la persona al momento de enfrentarse a la solución de un problema. Asumimos una naturaleza de la noción de variación como red semántico operacional transversal, que imbrica distintos contenidos escolares de ciencia experimental y de matemática, particularmente aquellos de tiempo y velocidad. Entendemos al tiempo cotidiano formado por una red compleja de intencionalidades y coordinaciones que se estructuran a partir de las necesidades de coordinación con lo otro, con los otros y de las proyecciones intencionales hacia un futuro y un pasado, y, al tiempo matemático en su calidad de parámetro y figurado sobre la base de la metáfora de una distancia horizontal. A continuación se analizan, desde ese marco conceptual, las herramientas a que recurren profesores para comunicar cambios en una situación específica desarrollada en el marco las actividades del Proyecto de Investigación Las representaciones docentes del Cambio.

El aprendizaje activo de la microbiología en el Grado de Podología incrementa el rendimiento académico

Se ha planteado como objetivo la mejora de la calidad de la docencia de la Microbiología mediante la actualización de la metodología docente , introduciendo como actividad docente el aprendizaje activo basado en preguntas (inquirybased learning:IBL) para conseguir mejorar las competencias que deberán adquirir los estudiantes como parte de su formación integral. En este estudio han participado 55 alumnos de Segundo Curso del Grado de Podología (Curso 2014-2015),y se ha calculado el porcentaje de alumnos que participaron en las 3 pruebas (3 IBL), en 2 (2 IBL), en 1 (1 IBL), y los que no participaron en ninguna y posteriormente se relacionó con las calificaciones obtenidas en la asignatura de Microbiología. Se incluyeron las preguntas IBL que se realizaron en clase en el campus virtual de la asignatura, pero sin incluir la corrección de las mismas. En los alumnos que realizaron alguna prueba IBL se obtuvieron calificaciones mejores en las preguntas diseñadas para analizar la síntesis de conocimientos y el análisis de datos que en aquellos que no habían participado en ninguna. Al finalizar la actividad se realizó un estudio transversal a través de un cuestionario autocumplimentado en el que se valoraba la opinión de los alumnos sobre el aprendizaje activo mediante IBL valorando positivamente esta actividad para medir el aprendizaje y mejorar la preparación del examen. Consideramos que el uso del campus virtual unido a la actualización en la metodología docente puede mejorar el rendimiento académico de los estudiantes de Microbiología.

Conscientiousness and laboriousness as academic achievement predictors in a Spanish students sample

To understand academic performance of students, the variable of conscientiousness from personality inventory Big Five, has been recognized as an important key. The aim of this paper is to analyze the relationship established between the personality factor conscientiousness itself and two of its facets, laboriousness and planning, with academic performance, and observe if there are genre differences in consciousness personality factor. A total of 456 Spanish students of high school and college participated in the study. They were requested to answer a personality report and a self inform questionnaire. The results show that both conscientiousness as a personality dimension and the consideration of laboriousness facet are able to predict academic performance, especially with regard to student’s exam marks, classroom attendance and dedication to study. The genre variable pointed out that feminine genre is more conscious than male in that personality factor. From a practical perspective, these results indicate that the establishment of a routine of continuous work is suitable for improving student grades and their adaptation to the educational environment.

Predictors of attitudes toward inclusion of students with special educational needs in future education professionals

One of the main pillars in the development of inclusive schools is the initial teacher training. Before determining if it is necessary to make changes (and of what type) in training programs or curriculum guides related to the attention to diversity and inclusive education, the attitudes of future education professionals in this area should be analyzed. This includes the identification of the relevant predictors of inclusive attitudes. The research reported in this article pursued this objective, doing so with a quantitative survey methodology based on the use of cross-sectional structured data collection and statistical analyses related to the quality of the attitude questionnaire (factor analysis and Cronbach's alpha), descriptive statistics, correlations, hypothesis tests for difference of means, and regression analysis in order to predict attitudes towards inclusion in education. Firstly, the results show that the participants held very positive attitudes toward the inclusion of students with special educational needs. Particularly, older respondents, those with a longer training and, to a lesser extent, women and those who had been in touch with disabled people stood out within this attitude. Secondly, it is evidenced that self-transcendence values ​and, more weakly, contact, function as robust predictors of attitudes of future practitioners towards the inclusion of students with special needs. Some applications for the initial professionalization of educators are suggested in the discussion.

¡Abre los ojos! Un proyecto de mejora educativa para la prevención de drogas en adolescentes

La Educación para la Salud (EpS) es un tema transversal del currículo que adolece de propuestas didácticas novedosas para la intervención pedagógica. El objetivo del trabajo que se presenta es poner en marcha un plan de mejora para la prevención de drogadicciones en adolescentes. Para ello, se ha trabajado con un total de 142 estudiantes de 3º de Educación Secundaria Obligatoria (ESO) con edades comprendidas entre los 14 y los 16 años que cursan estudios en el Instituto “Francisco Salzillo” de la localidad de Alcantarilla (Murcia). Concretamente, este artículo da luz al Proyecto ¡Abre los ojos!, que forma parte del Plan de Acción Tutorial (PAT) y del Plan de Mejora para la Prevención de Drogas (PMPD) propuesto desde el Departamento de Orientación. Se exponen ad hoc las actividades implementadas durante las 3 sesiones trabajadas con cada uno de los 6 grupos-clase escolarizados en este nivel. Haciendo uso de la reflexión-acción, el alumnado ha desarrollado una conciencia crítica acerca de los riesgos que entraña para la salud el consumo de drogas. Asimismo, mediante la técnica de grupos de discusión los discentes han realizado un interesante debate cuyas ideas han sido organizadas en torno a tres aspectos clave: causas por las que se empieza a consumir, cómo evitar caer en las drogas, y alternativas de ocio y tiempo libre para una vida saludable. Finalmente, se especifica la necesidad de abordar tareas de prevención en los centros educativos así como de facilitar información y de resolver las inquietudes de los jóvenes acerca de esta temática.

Students with disabilities in a Chilean university

The purpose of this article is to give a report about a research related with the conditions of inclusion of students with disability in a Chilean university. This research is a quantitative, descriptive and cross-sectional study. To collect the data required, a survey was developed, which was applied to 38 students with disability. The main results reveal a high retention rate of students, who exhibit a positive perception of their inclusion in their university life and also a high level of satisfaction with most of the services provided. Seven out of ten students surveyed recognize having received some sort of education care from their programs to pursue their studies. However, there still exists a lack of connection between the current initiatives developed at the university to support the enrollment and permanence of students. Added to this fact, there is a lack of protocols and training for teachers and staff. In this study it is proposed that the university must establish a management system that defines objectives, strategies and actions that contribute to improve inclusion of people with disabilities.

Alfvén Waves in the Lower Solar Atmosphere

The flow of energy through the solar atmosphere and the heating of the Sun's outer regions are still not understood. Here, we report the detection of oscillatory phenomena associated with a large bright-point group that is 430,000 square kilometers in area and located near the solar disk center. Wavelet analysis reveals full-width half-maximum oscillations with periodicities ranging from 126 to 700 seconds originating above the bright point and significance levels exceeding 99%. These oscillations, 2.6 kilometers per second in amplitude, are coupled with chromospheric line-of-sight Doppler velocities with an average blue shift of 23 kilometers per second. A lack of cospatial intensity oscillations and transversal displacements rules out the presence of magneto-acoustic wave modes. The oscillations are a signature of Alfvén waves produced by a torsional twist of ±22 degrees. A phase shift of 180 degrees across the diameter of the bright point suggests that these torsional Alfvén oscillations are induced globally throughout the entire brightening. The energy flux associated with this wave mode is sufficient to heat the solar corona.

Equalisation of time variant multipath channels using amplitude banded LMS algorithms

For the purpose of equalisation of rapidly time variant multipath channels, we derive a novel adaptive algorithm, the amplitude banded LMS (ABLMS); which implements a nonlinear adaptation based on a coefficient matrix. Then we develop the: ABLMS algorithm as the adaptation procedure for a linear transversal equaliser (LTE) and a decision feedback equaliser (DFE) where a parallel adaptation scheme is deployed. Computer simulations demonstrate that with a small increase of computational complexity, the ABLMS based parallel equalisers provide a significant improvement related to the conventional LMS DFE and the LMS LTE in the case of a second order Markov communication channel model.

Collaborative artistic laboratories. Transfrontier spaces of cultural production

The appearance of the open code paradigm and the demands of social movements have permeated the ways in which today’s cultural institutions are organized. This article analyzes the birth of a new critical and cooperative spatiality and how it is transforming current modes of cultural research and production. It centers on the potential for establishing the new means of cooperation that are being tested in what are defined as collaborative artistic laboratories. These are hybrid spaces of research and creation based on networked and cooperative structures producing a new societal-technical body that forces us to reconsider the traditional organic conditions of the productive scenarios of knowledge and artistic practice.

Gender and Cosmopolitanism in Europe: A Feminist Perspective

Gender and Cosmopolitanism in Europe combines a feminist critique of contemporary and prominent approaches to cosmopolitanism with an in-depth analysis of historical cosmopolitanism and the manner in which gendered symbolic boundaries of national political communities in two European countries are drawn. Exploring the work of prominent scholars of new cosmopolitanism in Britain and Germany, including Held, Habermas, Beck and Bhabha, it delivers a timely intervention into current debates on globalisation, Europeanisation and social processes of transformation in and beyond specific national societies.

A rigorous examination of the emancipatory potential of current debates surrounding cosmopolitanism in Europe, this book will be of interest to sociologist and political scientists working on questions of identity, inclusion, citizenship, globalisation, cosmopolitanism and gender.

Gestão de resíduos sólidos urbanos (RSU) em territórios rurais: caracterização, problemas e propostas de intervenção no concelho de Anadia

Num mundo cada vez mais industrializado e consumista, com assimetrias territoriais várias, a defesa dos valores ambientais assume uma progressiva importância, uma vez que a qualidade de vida passa também pela qualidade ambiental. Como os produtos gerados pelo consumo devem ter o confinamento correto em função das suas diversas componentes, a gestão do processo de deposição, recolha e transporte de RSU, fica mais complexa, à medida que a população e a área se diversifica e expande, como acontece em alguns territórios rurais, agravando os custos e os impactos ambientais induzidos, se não for equacionada uma solução simultaneamente eficaz e eficiente. Paralelamente urge a satisfação dos residentes e dos restantes utilizadores enquanto usuários desses territórios. Por este motivo, nos últimos anos, as autarquias têm vindo a estudar essas soluções nas suas áreas de jurisdição, tentando com as ações realizadas, respeitar não só os critérios de proteção ambiental, mas também as necessidades das pessoas. Neste trabalho apresentam-se algumas variáveis identificadas, como resultados de um estudo de caso aplicado a um município rural, Anadia, onde se evidencia a ausência de sensibilização e a carência de meios e processos que podem comprometer as metas ambientais e sociais desejadas. In a world, progressively more industrialized and consumer, with several territorial disparities, the protection of environmental values assumes an increasingly importance, since the quality of life also involves environmental quality. As the products generated by the consumption must have a correct confinement in its various components, the management of the deposition process, collection and transportation of municipal solid waste, is more complex, as the population and the area expand, as happens in some rural territories, increasing the cost and environmental impacts induced, if not equated a solution both effective and efficient. At the same time it is very important to increase the satisfaction of residents, visitors and tourists visiting these areas. For this reason, in the last years, the municipalities have been studying these solutions in their areas of jurisdiction. That is why they try to respect not only the criteria of environmental protection, but also the needs of people and fulfilled actions whose variables we shall try to present as a case study applied to a rural municipality, Anadia, where we show up that the absence of awareness and the lack of means and processes can compromise the desired environmental and social goals
