    Learning by discussion when applied to on-line collaborative learning settings can provide significant benefits for students in education in general. Indeed, the discussion process plays an important social task in collaborative learning practices. Participants can discuss about the activity being performed, collaborate with each other through the exchange of ideas that may arise, propose new resolution mechanisms, justify and refine their own contributions, and as a result, acquire new knowledge. Considering these benefits, current educational organizations incorporate on-line discussions into web-based courses as part of the very rationale of their pedagogical models. However, in-class collaborative assignments are usually greatly participated and contributed, which makes the monitoring and assessment tasks by tutors and moderators time-consuming, tedious and error-prone. Specially hard if not impossible by human tutors is to manually deal with the sequences of hundreds of contributions making up the discussion threads and the relations between these contributions. Consequently, tutoring tasks during on-line discussions usually restrict to offer evaluation results of the contributing effort and quality after the collaborative learning activity takes place and thus neglect the essential issue of constantly considering the process of knowledge building while it is still being performed. In this paper, we propose a multidimensional model based on data analysis from online collaborative discussion interactions that provides a first step towards an automatic evaluation in just-in-time fashion. The context of this study is a real on-line discussion experience that took place at the Open University of Catalonia.Peer ReviewedPostprint (published version

    Aquest treball de tesi proposa aportar una infraestructura de programari per donar suport a nous tipus de metodologies i recursos d'aprenentatge col路laboratiu augmentats pedag貌gicament i a trav茅s d'una plataforma d'aplicaci贸 innovadora anomenada Plataforma de Virtualitzaci贸 de Sessions Col路laboratives (VCSF de l'angles Virtualized Collaborative Sessions Framework). El VCSF ajuda a satisfer els requisits pedag貌gics exigents de l'aprenentatge col路laboratiu en l铆nia d鈥檃vui en dia, com ara augmentar la participaci贸 de l'estudiant i millorar el rendiment de l'aprenentatge durant la col路laboraci贸. Al seu torn, l'aplicaci贸 sistem脿tica de la plataforma VCSF, enriquida amb tecnologies sem脿ntiques, permet als desenvolupadors d'e-learning aprofitar experi猫ncies d'aprenentatge col路laboratiu pr猫vies a trav茅s de la reutilitzaci贸 de programari, estalviant temps de desenvolupament i esfor莽. La plataforma ha sigut prototipada i provada amb 猫xit en entorns reals, el que demostra la capacitat de reutilitzaci贸 del programari i els beneficis pedag貌gics de l'enfocament VCSF.Este trabajo de tesis propone aportar una infraestructura de software para apoyar a nuevos tipos de metodolog铆as y recursos de aprendizaje colaborativo aumentados pedag贸gicamente ya trav茅s de una plataforma de aplicaci贸n innovadora llamada Plataforma de Virtualizaci贸n de Sesiones Colaborativa (VCSF del ingl茅s Virtualized Collaborative Sessions Framework). El VCSF ayuda a satisfacer los requisitos pedag贸gicos exigentes del aprendizaje colaborativo en l铆nea de hoy en d铆a, tales como aumentar la participaci贸n del estudiante y mejorar el rendimiento del aprendizaje durante la colaboraci贸n. A su vez, la aplicaci贸n sistem谩tica de la plataforma VCSF, enriquecida con tecnolog铆as sem谩nticas, permite a los desarrolladores de e-learning aprovechar experiencias de aprendizaje colaborativo previas a trav茅s de la reutilizaci贸n de software, ahorrando tiempo de desarrollo y esfuerzo. La plataforma ha sido prototipada y probada con 茅xito en entornos reales, lo que demuestra la capacidad de reutilizaci贸n del software y los beneficios pedag贸gicos del enfoque VCSF.This thesis project aims to provide a software infrastructure to support new types of pedagogically augmented collaborative learning methodologies and resources by means of an innovative application framework called Virtualized Collaborative Sessions Framework (VCSF). The VCSF helps meet challenging pedagogical requirements in online collaborative learning, such as increasing students' engagement and learning performance during the collaboration. In turn, the systematic application of the VCSF platform, enriched with semantic technologies, enables e-learning developers to leverage successful collaborative learning experiences through software reuse, saving in both development time and effort. The framework has been prototyped and successfully tested in real environments, thus showing the software reuse capability and the pedagogical benefits of the VCSF approach

    Proposem un proc茅s de virtualitzaci贸 de sessions col路laboratives en directe a partir de f貌rums de discussi贸 i xats web amb l'objectiu de produir recursos d'aprenentatge en l铆nia interactius per a ser utilitzats pels alumnes i generar un efecte positiu en la participaci贸 de l'alumne. Per tal de millorar encara m茅s la implicaci贸 de l'aprenentatge, vam dotar al nostre proc茅s de virtualitzaci贸 d'un marc d'avaluaci贸 m煤ltiple que proporciona la consci猫ncia efectiva i la retroalimentaci贸 constructiva als alumnes de la col路laboraci贸 original amb interaccions entre els membres del grup. La investigaci贸 presentada es centra en l'avaluaci贸 electr貌nica d'aprenentatge col路laboratiu i social i s'est茅n amb anal铆tiques d'aprenentatge i t猫cniques d'an脿lisi de xarxa social que s贸n capaces d'analitzar i representar les interaccions cognitives i socials amb sessions de col路laboraci贸 en viu subjacents.Proponemos un proceso de virtualizaci贸n de sesiones colaborativas en directo a partir de foros de discusi贸n y chats web con el objetivo de producir recursos de aprendizaje en l铆nea interactivos para ser utilizados por los alumnos y generar un efecto positivo en la participaci贸n del alumno. Con el fin de mejorar a煤n m谩s la implicaci贸n del aprendizaje, dotamos a nuestro proceso de virtualizaci贸n de un marco de evaluaci贸n m煤ltiple que proporciona la conciencia efectiva y la retroalimentaci贸n constructiva a los alumnos de la colaboraci贸n original con interacciones entre los miembros del grupo. La investigaci贸n presentada se centra en la evaluaci贸n electr贸nica de aprendizaje colaborativo y social y se extiende con anal铆ticas de aprendizaje y t茅cnicas de an谩lisis de red social que son capaces de analizar y representar las interacciones cognitivas y sociales con sesiones de colaboraci贸n en vivo subyacentes.We propose a virtualization process of live collaborative sessions from Web discussion forums and chats with the aim to produce interactive and attractive online learning resources to be used by learners, thus having a positive effect in learner engagement. In order to enhance further learning engagement, we endow our virtualization process with a multifold assessment framework that provides effective awareness and constructive feedback to learners from the original collaborative interactions among group members. The research presented focuses on e-assessment of collaborative and social learning and extends it with Learning Analytics and Social Network Analysis techniques that are able to analyse and represent cognitive and social interactions underlying live collaborative sessions
