Human-Computer Interaction with older people through ethnographical lenses: everyday interactions with ICT

Report for the scientific sojourn carried out at the School of Computing of the University of Dundee, United Kingdom, from 2010 to 2012. This document is a scientific report of the work done, main results, publications and accomplishment of the objectives of the 2-year post-doctoral research project with reference number BP-A 00239. The project has addressed the topic of older people (60+) and Information and Communication Technologies (ICT), which is a topic of growing social and research interest, from a Human-Computer Interaction perspective. Over a 2-year period (June 2010-June 2012), we have conducted classical ethnography of ICT use in a computer clubhouse in Scotland, addressing interaction barriers and strategies, social sharing practices in Social Network Sites, and ICT learning, and carried out rapid ethnographical studies related to geo-enabled ICT and e-government services towards supporting independent living and active ageing. The main results have provided a much deeper understanding of (i) the everyday use of Computer-Mediated Communication tools, such as video-chats and blogs, and its evolution as older people’s experience with ICT increases over time, (ii) cross-cultural aspects of ICT use in the north and south of Europe, (iii) the relevance of cognition over vision in interacting with geographical information and a wide range of ICT tools, despite common stereotypes (e.g. make things bigger), (iv) the important relationship offline-online to provide older people with socially inclusive and meaningful eservices for independent living and active ageing, (v) how older people carry out social sharing practices in the popular YouTube, (vi) their user experiences and (vii) the challenges they face in ICT learning and the strategies they use to become successful ICT learners over time. The research conducted in this project has been published in 17 papers, 4 in journals – two of which in JCR, 5 in conferences, 4 in workshops and 4 in magazines. Other public output consists of 10 invited talks and seminars.

Emotion and reason in everyday risk perception

Although research has documented the importance of emotion in risk perception, little is knownabout its prevalence in everyday life. Using the Experience Sampling Method, 94 part-timestudents were prompted at random via cellular telephones to report on mood state and threeemotions and to assess risk on thirty occasions during their working hours. The emotions valence, arousal, and dominance were measured using self-assessment manikins (Bradley &Lang, 1994). Hierarchical linear models (HLM) revealed that mood state and emotions explainedsignificant variance in risk perception. In addition, valence and arousal accounted for varianceover and above reason (measured by severity and possibility of risks). Six risks were reassessedin a post-experimental session and found to be lower than their real-time counterparts.The study demonstrates the feasibility and value of collecting representative samples of data withsimple technology. Evidence for the statistical consistency of the HLM estimates is provided inan Appendix.

What risks do people perceive in everyday life? A perspective gained from the experience sampling method (ESM)

The experiential sampling method (ESM) was used to collect data from 74 parttimestudents who described and assessed the risks involved in their current activitieswhen interrupted at random moments by text messages. The major categories ofperceived risk were short-term in nature and involved loss of time or materials relatedto work and physical damage (e.g., from transportation). Using techniques of multilevelanalysis, we demonstrate effects of gender, emotional state, and types of risk onassessments of risk. Specifically, females do not differ from males in assessing thepotential severity of risks but they see these as more likely to occur. Also, participantsassessed risks to be lower when in more positive self-reported emotional states. Wefurther demonstrate the potential of ESM by showing that risk assessments associatedwith current actions exceed those made retrospectively. We conclude by notingadvantages and disadvantages of ESM for collecting data about risk perceptions.

La praxis reflexiva: un reto para la educación social

La educación social en sus diversas acepciones (profesión, práctica educativa y estudios universitarios) ha experimentado unos importantes cambios en los últimos años. De una actividad centrada en la solución de problemas concretos dentro de un ámbito específico, se ha ido avanzando hacia la necesidad de estar capacitado para el trabajo en entornos complejos y difusos. El ejercicio de la actividad en estos entornos requiere de un posicionamiento estratégico, de una visión global más allá de un manejo de recetas cerradas y de una perspectiva ética que trascienda el simple cumplimiento de instrucciones. Por ello, capacitar al profesional para el diseño y la aplicación de las acciones socioeducativas es una temática que requiere la integración de multiplicidad de competencias para que cada intervención sea una respuesta que se adapte a la situación, a las capacidades y al contexto de la persona atendida. En el periodo de formación universitaria, el practicum es un espacio de aprendizaje privilegiado donde se ponen en juego todos los conocimientos adquiridos y sirve de trampolín para empezar a ejercer la profesión en un contexto real pero seguro, que más adelante será el escenario cotidiano de la acción profesional

La influencia del lenguaje cotidiano en el desarrollo de la escritura de los inmigrantes en los centros educativos

El objetivo de nuestra investigación es demostrar la importancia deluso de la lengua escolar fuera del entorno educativo y como este uso podría repercutir notablemente en el rendimiento académico del alumnado inmigrante. Según nuestra hipótesis, los alumnos inmigrantes que no practican en su vida cotidiana la lengua que se usa en los centros educativos realizarán más errores en la escritura que aquellos alumnos inmigrantes que sí practican dicho lenguaje fuera del entorno educativo. Las técnicas que emplearíamos para recopilar y clasificar la información serían cuestionarios y un corpus lingüístico. Los resultados que esperamos obtener son un número considerablemente alto de errores en la escritura por parte de los alumnos inmigrantes que no hablan el catalán en su entorno social no escolar, mientras que los alumnos autóctonos y los alumnos inmigrantes que sí practican el catalán fuera del ámbito educativo obtendrían mejores resultados. Estos resultados nos proporcionarían una evidencia más sobre la importancia del uso de las lenguas escolares en entornos no escolares.

Cómo enseñar matemáticas en las primeras edades a partir de contextos de vida cotidiana = How to teach mathematics to young students based on everyday contexts

This paper stresses the importance of developing mathematical thought in young children based on everyday contexts, since these are meaningful learning situations with an interdisciplinary, globalised focus. The first part sets out the framework of reference that lays the theoretical foundations for these kinds of educational practices. The second part gives some teaching orientations for work based on everyday contexts. It concludes with the presentation of the activity 'We’re off to the cinema to learn mathematics!'
