- Accessibility Requirements for educational packages in dotLRN
- Abstract: dotLRN open source developers community is making a great effort to improve the user interface of this learning management system and to adapt it to the accessibility requirements proposed by the W3C Web Accessibility Initiative. This paper contributes to this task by analyzing the current accessibility status of three fundamental packages for dotLRN future: LORS, Assessment and IMS-LD and providing appropriate recommendations. These packages provide the educational standards support in the platform. More specifically, they implement SCORM, IMS-CP, IMS-QTI, IMS-LD and IMSMD

- Usability in e-Learning Platforms: heuristics comparison between Moodle, Sakai and dotLRN
- Abstract: Recently, educational institutions largely adopted open source elearning platforms. Several studies and comparisons between those platforms were conducted. However, these analyses were more focused into purely technical issues (standards support, development platform used, scalability, etc.) than into functional issues. It was noted that most of the e-learning solutions are not optimal from the end-user point of view: they can be hard and tedious to use, potentially resulting in higher abandon rates. There is therefore a need to focus into usability to work toward more usable and user-centered elearning platforms. This paper details the used methodology based on heuristics to allow an objective usability evaluation of three of the main e-learning open source platforms: Moodle, Sakai and dotLRN. The results of the comparative evaluations are exposed.

- Ten requirements for eLearning platforms to support disabled teachers
- Abstract: Requirements for eLearning platforms have usually focused on the learners’ needs. However, very little studies analyze the required support from the teachers’ perspective, especially when the teachers have one or more disabilities. I have analyzed the problems disabled teachers face at the workplace and identified ten requirements for eLearning platforms to overcome them.

- E-learning: a tool for teachers with a disability
- Springer LNCS online version
- Abstract: Usability and accessibility in e-Learning has usually focused on the learners’ experience and how to improve the learning efficiency. However, very little studies analyze the accessibility and usability issues from the teachers’ point of view, especially when the teachers have one or more disabilities. Teachers with disabilities find it very difficult to manage in their off-line jobs. Therefore, it is expected that technology can make them easier to work as online teachers. In this paper, I will summarize which troubles Spanish teachers with disabilities at Elementary degree find out in their job and how the elearning can improve their quality of job life.

- How accessibility issues affect Information Architecture
- Abstract: When designing complex systems, applications, websites, etc., accessibility issues should be considered before the very first line is skecthed on the initial draft proposal for the design, not only for governmental and corporate websites, but also for advertising products or intranets. However, accepting the user diversity implies a certain number of constrains and requirements that have to be taken into account when creating our prototypes. This will allow us to save time, money and gain sustainability in our projects.

- From consultancy to teaching
- Abstract:I had been invited to teach User Centred Design (UCD) at a university. Being a 32-year-old User Experience (UX) consultant with a work experience of ten years, should be a great background for transmitting my know-how to 19-year-old Design students. Suddenly, I realized that most of my knowledge in the field has come from non-university methods: jobs, blogs, Internet references, books, etc.; all not very scientific stuff for teaching at the university. So I started to research what was taught in other places about UCD and found that very little was done at universities. (Or public information was very difficult to find.) Then I turned to the places where I had learned and noticed that this discipline (I still don’t consider it a ‘science’) is mostly done by non-scientific professionals of design, librarianship, engineering and hundreds of other different backgrounds and profiles that had all given their “two cents worth” based on their experience. So here are my “two cents worth” based on my experience, what I learned and what I teach on my courses.

- Reducing techno-anxiety in high school teachers by improving their ICT problem-solving skills
- Abstract:Teachers need to continuously update their information and communication technologies (ICT) knowledge, but they are usually not trained to deal with the problems arising from their use. In fact, studies in the literature report techno-anxiety (i.e. unpleasant physiological activation and discomfort due to present or future use of ICT) in teachers. Thus, the goal of this action research is to study if teachers’ techno-anxiety can be reduced by increasing their ability to solve technological problems. An inter-subject experiment has been carried out with 46 teachers. High school teachers were chosen because they are digital immigrants, while at the moment of this research their students are digital natives (born around year 2000). Since we could not find any specific training for teachers to increase their resolution skills of technological problems, in order to apply the treatment for our study, we have designed and deployed an online course about ICT problem-solving skills based on the 70/20/10 model for learning and development. Results show the success of the course when it comes to increasing the ICT problem-solving skills and to reducing techno-anxiety.

- The Skills, Competences, and Attitude toward Information and Communications Technology Recommender System: an online support program for teachers with personalized recommendations
- Abstract:Teachers deal with Information and Communications Technology (ICT) every day and they often have to solve problems by themselves. To help them in coping with this issue, an online support program has been created, where teachers can pose their problems on ICT and they can receive solutions from other teachers. A Recommender System has been defined and implemented into the support program to suggest to each teacher the most suitable solution based on her Skills, Competences, and Attitude toward ICT (SCAT-ICT). The support program has initially been populated with 70 problems from 86 teachers. 30 teachers grouped these problems into six categories with the card-sorting technique. Real solutions to these problems have been proposed by 25 trained teachers. Finally, 17 teachers evaluated the usability of the support program and the Recommender System, where results showed a high score on the standardized System Usability Scale.

- Influencia de la capacidad de resolución de problemas relacionados con la tecnología en el tecnoestrés de profesores de secundaria
- Resumen:Los profesores de secundaria se enfrentan a una constante obligación de mantenerse actualizados en Tecnologías de la Información y Comunicación (TIC). Sin embargo, nadie les da formación o soporte sobre cómo afrontar los problemas derivados del uso de las TIC. Algunos de ellos pueden contactar con personal técnico o preguntar a otros compañeros, pero en muchas ocasiones tienen que arreglárselas por sí mismos. Por otro lado, el estrés es uno de los principales problemas que tienen los profesores de secundaria. Parte de este estrés global deriva del tecnoestrés, o estrés generado por el uso de las TIC. El tecnoestrés es un constructo complejo, y del que existen diferentes tipologías. En esta investigación se han tenido en cuenta dos tipologías: la tecnoansiedad y la tecnofatiga. Para solventar ambos problemas, esta investigación se pone como objetivo ayudar a los profesores de secundaria a reducir su tecnoestrés al mismo tiempo que se aumente su capacidad de resolución de problemas tecnológicos. Para ello se han enunciado tres hipótesis: I. Se puede aumentar la capacidad de resolución de problemas relacionados con la tecnología por medio de un curso en línea. II. La tecnofatiga puede disminuir a medida que aumenta la capacidad de resolver problemas relacionados con la tecnología III. La tecnoansiedad puede disminuir a medida que aumenta la capacidad de resolver problemas relacionados con la tecnología Para ello se ha realizado un experimento intersujeto con un grupo experimental y otro grupo de control, cada uno de 23 profesores. El grupo experimental siguió un curso en línea basado en el modelo educativo 70/20/10 de «Resolución de problemas relacionados con la tecnología» durante 10 semanas, mientras que el grupo de control no siguió el curso. A ambos grupos se les ha medido sus niveles de tecnoestrés antes y después del curso, así como su capacidad de resolución de problemas relacionados con la tecnología. La medición del tecnoestrés se ha realizado con el cuestionario RED_Tecnoestrés La capacidad de resolución de problemas se ha medido mediante la metodología propuesta por Molleda et al. en «La adquisición de competencias transversales en la universidad. Aplicación a la resolución de problemas», presentada en las IX Jornadas Redes de Investigación en Docencia Universitaria de 2011. Los resultados ponen de manifiesto el éxito del curso a la hora de aumentar la capacidad de resolución de problemas, y de reducir la tecnoansiedad, ambos con diferencias estadísticamente significativas. Sin embargo, la tecnofatiga no muestra signos de variación evidentes, por lo que se hace necesario revisar el planteamiento del curso para cubrir esta necesidad.

- WAI-ARIA: el gran desconocido de la accesibilidad web
- Resumen: Las aplicaciones web cuentan muchas veces con controles no nativos, habitualmente desarrollados con JavaScript, que no permiten a los lectores de pantalla interpretarlos correctamente, por lo que los usuarios de estos productos no pueden comprenderlas y manejarlas correctamente. Para solucionar este problema, el grupo del W3C llamado WAI (Iniciativa de Accesibilidad Web) creó la tecnología ARIA (Accesible Rich Internet Application). ARIA permite añadir información semántica a estos controles no nativos, de tal modo que los navegadores pueden informar a los lectores de pantalla, y de este modo sus usuarios puedan interaccionar con la aplicación web.
