Virtu@l-ApS: Technological Support for Virtual Service-Learning

El Aprendizaje-Servicio Virtual (ApSV) es el Aprendizaje-Servicio (ApS) mediado por las TIC (Tecnologías de la Información y la Comunicación) –tanto para la prestación del servicio como para el apoyo, monitorización y evaluación del aprendizaje por parte de los docentes− y concebido para situaciones en que la comunicación cara a cara entre estudiantes, profesores y beneficiarios del servicio no es posible. La experiencia ha demostrado que sería de gran interés disponer de una aplicación web para el soporte del ApSV (y, en general, de ApS). Presentamos aquí el desarrollo de dicha aplicación web: Virtu@l-ApS. Hasta la fecha, este proyecto de desarrollo de software se ha llevado a cabo en el marco de dos Proyectos de Fin de Grado colaborativos e interdisciplinares de la Universidad Nacional de Educación a Distancia (UNED), de los grados en Educación Social e Ingeniería Informática, respectivamente. Aunque la versión de la aplicación web actualmente disponible carece de importantes funcionalidades, la experiencia de su desarrollo ha sido extremadamente útil, en particular, para la clarificación de los requisitos de una aplicación real, completamente operativa, que esperamos contribuya al soporte y la expansión del ApS en la Enseñanza Superior en España.

Entre sus investigaciones en torno al exilio republicano, la entrevista destaca sus trabajos sobre las consecuencias del exilio y la guerra civil para la infancia.

Estrategias de enseñanza en los entornos mediados: resultados de la experiencia de la performance virtual educativa

In this article, we present a teaching and learning experience that we call virtual performance based on the theatricalisation of educational roles developed through online synchronous meetings between students, moderated by the teaching team. The educational performances were related to content on teaching roles and stereotypes in education, where part of the programmatic content of the subjects served as a basis for the search for explanations associated with the technical development of the performances. The experience was developed in the Universidad Nacional de Educacion a Distancia (UNED) and the Universidad Nacional de Quilmes (UNQ), in two postgraduate courses that are taught through virtual environments, and related to communication, to Education and to educational technology. This paper presents the results of the development of this virtual educational performance experience in both universities, from the analysis of data that was collected throughout the stages of its implementation, which allows to characterize it as an innovative synchronous experience in teaching in virtual environments.

CURRICULAR ADAPTATIONS FOR DEAF AND HARD OF HEARING STUDENTS AT UNED UNIVERSITY

INTRODUCTION . This paper examines the degree of satisfaction with curricular adaptations shown by deaf and hard of hearing students enrolled at the Universidad Nacional de Educacion a Distancia (UNED), as well as the resulting benefits they perceived in terms of their selfefficacy, reduction in pre-examination anxiety and social support for study. METHOD . A total of 133 students with hearing disabilities participated in this study. Out of these 133 students, 28 were accorded some kind of adaptation, which represented almost all (84.84%) of the students at UNED who have received an adaptation. Data collection was achieved via an online questionnaire designed specifically for this study. All analyses were performed using statistical software package SPSS for Windows, version 21.0. RESULTS . The results indicate a high level of perceived satisfaction among students who were accorded curricular adaptations, and a relationship was observed between the demand for adaptations and student satisfaction. The results also reveal that the greatest perceived benefit was obtained in relation to a reduction in anxiety in examination situations, followed, although moderately, by benefits in relation to selfefficacy and social support. DISCUSSION . It is necessary to continue conducting an in-depth exploration of how the request for adaptions and the concession of them can influence the academic life of students with disabilities. Here, the aim is to achieve full inclusion in university life and the acquisition of the competencies that will equip students with disabilities to enter the labour market with the same opportunities as other students.

The Role of Hypothesis Testing in the Molding of Econometric Models

The paper is a keynote lecture from the Tilburg-Madrid Conference on Hypothesis Tests: Foundations and Applications at the Universidad Nacional de Educacion a Distancia (UNED) Madrid, Spain, 15-16 December 2011. It addresses the role of tests of statistical hypotheses (specification tests) in selection of a statistically admissible model in which to evaluate economic hypotheses. The issue is formulated in the context of recent philosophical accounts on the nature of models and related to some results in the literature on specification search.

Propagation of Nuclear Data Uncertainties in Transmutation Calculations Using ACAB Code

Departamento de Ingeniera Energetica, Universidad Nacional de Educacion a Distancia (UNED), 28004 Madrid, Spain(Received 26 April 2010)The assessment of the accuracy of parameters related to the reactor core performance (e.g.,ke ) and fuel cycle (e.g., isotopic evolution/transmutation) due to the uncertainties in the ba-sic nuclear data (ND) is a critical issue. Di erent error propagation techniques (adjoint/forwardsensitivity analysis procedures and/or Monte Carlo technique) can be used to address by computa-tional simulation the systematic propagation of uncertainties on the nal parameters. To performthis uncertainty assessment, the ENDF covariance les (variance/correlation in energy and cross-reactions-isotopes correlations) are required.In this paper, we assess the impact of ND uncertainties on the isotopic prediction for a concep-tual design of a modular European Facility for Industrial Transmutation (EFIT) for a dischargeburnup of 150 GWd/tHM. The complete set of uncertainty data for cross sections (EAF2007/UN,SCALE6.0/COVA-44G), radioactive decay and ssion yield data (JEFF-3.1.1) are processed andused in ACAB code.

Maltrato psicológico: la importancia de su detección a partir de un caso clínico [Psychological maltreatment: The relevance of its detection from a clinical case

The evaluation, diagnosis and treatment of a psychological maltreatment case treated at the Applied Psychology Service of Universidad Nacional de Educacion a Distancia (UNED) are described. The maltreatment facts caused severe depressive and anxious symptoms to the victim, as well as severe intrusive thoughts. This symptomatology became more activated when the patient noticed her husband's infidelity. Difficulties to realise it was a psychological maltreatment case and the aggressor tricks to avoid the victim receives therapy are discussed.

Virtual and remote control labs using Java: a qualitative approach

This article describes a new way of teaching adopted at the Universidad Nacional de Educacion a Distancia (UNED) that uses dynamic and interactive simulations in a stand-alone or Web-based environment to permit control engineering students to do practical work at a distance. The article focuses on how this new stand-alone experimentation environment maintains a clear separation between the graphical experimentation interface, developed in Java, and the math and simulation engine. By constructing the environment in this fashion, the math engine can be replaced with a different one or with a real plant, or can even be ported to a remote server. A Web-based, multiuser virtual lab is also possible without the necessity of reprogramming the experimentation interface code. Other differences with respect to tools are the dynamic simulations, the user interactivity, the generation of new experiments as goals change, and the opportunity to practice with classical or advanced control strategies in different plants: a heat exchanger, a tank, a distillation column, or an inverted pendulum.

Adaptive Web site for distance learning

University distance learning is benefiting from the intensive use of Internet resources. The variety of information and services offered, together with different kinds of students, are impeding efficient use of this medium. In order to alleviate these problems and other associated ones, a Web site is being developed to facilitate personalised access to these resources. This site is based on three essential elements: new teaching materials to make the most of the medium, alternative teaching organisation adapted to the requirements of the different protagonists (students, lecturers and tutors) and an interactive system, WebDL, which facilitates personalised and adaptive access to information and communication requirements to each and every user at each and every moment. To date, the resources and material for three computer studies courses are being developed at Universidad Nacional de Educacion a Distancia (UNED), whose delivery depends on the Artificial Intelligence Department.
