Utilización de la música en educación física: principales problemas

La utilización de la música para el desarrollo de las clases de Educación Física nos puede ofrecer multitud de posibilidades, convirtiéndose en un elemento indispensable para alcanzar objetivos didácticos. Pero la realidad docente está muy lejos de aprovechar el potencial que la música ofrece, tendiendo a un escaso uso, que casi siempre se cierne al contenido de Expresión Corporal, actualmente denominado en los contenidos oficiales, Ritmo y Expresión. Hemos realizado un estudio cuyo objetivo es conocer como el profesor de Educación Física utiliza la música en sus clases y cuales son los principales motivos que causan tal deficiencia. Para obtener los datos aplicamos un cuestionario de opinión que fue contestado por el 95% de los profesores de Educación Física que imparten clase en primer ciclo de la E.S.O. de la Región de Murcia. De los resultados obtenidos podemos extraer que aunque el profesor tiene una valoración positiva sobre la música, el principal factor que influye en su falta de utilización es la escasa formación que ha recibido durante sus estudios, tanto a nivel inicial como permanente

Estudio de la eficacia de un programa de intervención para la mejora de la habilidad de manejo de móviles en primaria

The objectives of this research were to test the effectiveness of an intervention program to improve the ability to handle mobile objects in primary school students and validate the use of an qualitative assessment tool to find out about different levels of difficulty. Two hypothesis are under study: a) the program will improve the skill level of the students and b) the scale of motor tasks is an appropriate tool for its evaluation. We worked with a sample of 148 students from Primary School and used a pretest-postest design with a control group and two observations after the application of the program. We applied a scale of 15 tasks for the assessment of the ability to handle mobile objects. In the application phase was implemented an intervention program for the improvement of the skills being studied within the experimental group was implemented. The results indicated that the scale was an appropriate tool to assess the degree of difficulty of the tasks. In addition, it obtained a high retention level, in all tasks regarding the experimental group one month after the program application. The most important is that the intervention program is offered as a valid alternative methodology to improve those skills.Los objetivos de la presente investigación fueron comprobar la efectividad de un programa de intervención para mejorar la habilidad de manejo de móviles en el alumnado de Primaria y validar un instrumento de evaluación cualitativo para conocer los niveles de dificultad. Se plantearon dos hipótesis de estudio: a) el programa permite mejorar el grado de habilidad del alumnado y b) la escala de tareas motrices es un instrumento adecuado para su evaluación. Se trabajó con una muestra de 148 alumnos de Primaria empleando un diseño pretest-postest con grupo de control, con dos observaciones post-tratamiento. Se utilizo una escala compuesta por 15 tareas para la evaluación de la habilidad de manejo de móviles. En la fase de tratamiento se aplicó un programa de intervención para la mejora de las habilidades objeto de estudio. Los resultados indicaron que la escala fue un instrumento adecuado para valorar el grado de dificultad de las tareas. Además se obtuvo un alto nivel de retención, en todas las tareas, respecto al grupo tratado, un mes después del tratamiento. La conclusión más relevante es que el programa de intervención se ofrece como una alternativa metodológica válida para mejorar dichas habilidades

A risk society? Environmental hazards, risk and resilience in the later Middle Ages in Europe

Modern society is said to have restructured in reaction to contemporary hazards with the aim of improving its management of risk. This implies that pre-industrial societies were somehow fundamentally different. In this paper, we challenge that hypothesis by examining the ways in which risks associated with environmental hazards were managed and mitigated during the Middle Ages (defined here as the period from 1000 to 1550 AD). Beginning with a review of the many case studies of rapid onset disasters across Europe, we draw upon both historical and archaeological evidence and architectural assessments of structural damage for what is a pre-instrumental period. Building upon this, the second part of the paper explores individual outlooks on risk, emphasising the diversity of popular belief and the central importance of Christianity in framing attitudes. Despite their religious perspectives, we find that medieval communities were not helpless in the face of serious environmental hazards. We argue instead that the response of society to these threats was frequently complex, considered and, at times, surprisingly modern

Doping Liquid Argon with Xenon in ProtoDUNE Single-Phase: Effects on Scintillation Light

International audienceDoping of liquid argon TPCs (LArTPCs) with a small concentration of xenon is a technique for light-shifting and facilitates the detection of the liquid argon scintillation light. In this paper, we present the results of the first doping test ever performed in a kiloton-scale LArTPC. From February to May 2020, we carried out this special run in the single-phase DUNE Far Detector prototype (ProtoDUNE-SP) at CERN, featuring 770 t of total liquid argon mass with 410 t of fiducial mass. The goal of the run was to measure the light and charge response of the detector to the addition of xenon, up to a concentration of 18.8 ppm. The main purpose was to test the possibility for reduction of non-uniformities in light collection, caused by deployment of photon detectors only within the anode planes. Light collection was analysed as a function of the xenon concentration, by using the pre-existing photon detection system (PDS) of ProtoDUNE-SP and an additional smaller set-up installed specifically for this run. In this paper we first summarize our current understanding of the argon-xenon energy transfer process and the impact of the presence of nitrogen in argon with and without xenon dopant. We then describe the key elements of ProtoDUNE-SP and the injection method deployed. Two dedicated photon detectors were able to collect the light produced by xenon and the total light. The ratio of these components was measured to be about 0.65 as 18.8 ppm of xenon were injected. We performed studies of the collection efficiency as a function of the distance between tracks and light detectors, demonstrating enhanced uniformity of response for the anode-mounted PDS. We also show that xenon doping can substantially recover light losses due to contamination of the liquid argon by nitrogen
