Adoption of augmented reality technology by university students

In recent times, Augmented Reality has gained more relevance in the field of education. This relevance has been enhanced due to its ease of use, as well as the availability of the technical devices for the students. The present study was conducted with students enrolled in the Pedagogy Degree in the Faculty of Education at the University of Seville. The objective was to understand the degree of technological acceptance of students during their interaction with the AR objects produced, the performance achieved by the students, and if their gender affected their acquisition of knowledge. For this, three data collection instruments were utilized: a multiple choice test for the analysis of the student's performance after the interaction, the Technology Acceptance Model (TAM) diagnostic instrument, created by Davis (1989), and an “ad hoc” instrument created so that the students could evaluate the class notes enriched with the AR objects created. The study has allowed us to broaden the scientific knowledge of the TAM by Davis, to understand that AR objects can be utilized in university teaching, and to know that the student's gender does not influence learning.Ministry of Economy and Competitiveness of Spain EDU-5746-

PASTIS: Bayesian extrasolar planet validation. I. General framework, models, and performance

A large fraction of the smallest transiting planet candidates discovered by the Kepler and CoRoT space missions cannot be confirmed by a dynamical measurement of the mass using currently available observing facilities. To establish their planetary nature, the concept of planet validation has been advanced. This technique compares the probability of the planetary hypothesis against that of all reasonably conceivable alternative false-positive (FP) hypotheses. The candidate is considered as validated if the posterior probability of the planetary hypothesis is sufficiently larger than the sum of the probabilities of all FP scenarios. In this paper, we present PASTIS, the Planet Analysis and Small Transit Investigation Software, a tool designed to perform a rigorous model comparison of the hypotheses involved in the problem of planet validation, and to fully exploit the information available in the candidate light curves. PASTIS self-consistently models the transit light curves and follow-up observations. Its object-oriented structure offers a large flexibility for defining the scenarios to be compared. The performance is explored using artificial transit light curves of planets and FPs with a realistic error distribution obtained from a Kepler light curve. We find that data support for the correct hypothesis is strong only when the signal is high enough (transit signal-to-noise ratio above 50 for the planet case) and remains inconclusive otherwise. PLATO shall provide transits with high enough signal-to-noise ratio, but to establish the true nature of the vast majority of Kepler and CoRoT transit candidates additional data or strong reliance on hypotheses priors is needed.Comment: Accepted for publication in MNRAS; 23 pages, 11 figure

University services for the production of new technologies of information and communication. The construction and validation of instruments for evaluation and self evaluation

La universidad del siglo XXI requiere una transformación radical del papel de los dos actores fundamentales en el proceso de enseñanza-aprendizaje: el profesor (de actor a diseñador de situaciones y escenarios mediados de aprendizaje) y el alumno (de espectador a actor de su aprendizaje). En esta nueva situación, no debe caber duda de que las TIC, y especialmente las telemáticas, jugarán un papel muy significativo. Ello llevará necesariamente a que las universidades tengan que crear centros de ayuda a la producción audiovisual, multimedia y telemática para sus profesores, prever las necesidades de infraestructuras que se van a necesitar, y redefinir los servicios actualmente creados. Ante esta realidad, con este trabajo, hemos procedido al diseño de una guía (criterios y descriptores) para la evaluación, de indudable referente para la creación y desarrollo de estos servicios en las universidades como respuesta a los nuevos tiempos. Esto ha sido posible gracias a las aportaciones de un amplio número de investigadores y colaboradores que, mediante una combinación metodológica (análisis documental, análisis de web, entrevistas, cuestionario...), nos llevan a proponer un instrumento de evaluación de estos servicios, que bien podrían transferirse o generalizarse a otros contextos universitario

ICT and disabilities. Construction of a diagnostic instrument in Spain

This work presents the process of validation of a questionnaire that aims to determine the level of training and knowledge of teachers in the Spanish primary education, with respect to the application of the Information Technology and Communication (ICT) for people with disabilities. The structure of the instrument includes 6 dimensions: general, visual, hearing, motor, cognitive, and accessibility. The procedure considered the content validation, validation of construct through factor analysis and determination of reliability through Cronbach Alpha. The "expert judgement" technique, was used for the validation of content by applying a process of selection of experts at our educational research, the so-called expert coefficient or "K coefficient". The developed process made it possible to give scientific validity to the intended instrument

Conhecimento da TIC aplicadas às pessoas com incapacidade. Construção de um instrumento de diagnóstico

El artículo de investigación presenta el proceso de construcción y validación de un instrumento de diagnóstico elaborado con el objetivo de conocer el nivel de formación y conocimiento de los alumnos que cursan el grado de magisterio en España, con respecto a la aplicación de las Tecnologías de la Información y Comunicación para personas con discapacidades. Para la validación de contenido, se utilizó la técnica del juicio de experto, para aplicar un proceso de selección de expertos no muy usual en nuestra investigación educativa, el denominado “coeficiente de competencia experta” o “coeficiente K”.This paper studies the construction and validation process of a diagnostic instrument developed with the aim of knowing the level of education and knowledge of students enrolled in the bachelor of education program in Spain, regarding the implementation of Information and communication technologies among people with disabilities.
