    From 2000, mobile Learning (m-Learning) and ubiquitous Learning (u-Learning) has been the hottest research topic in e-learning, and now, integrating ubiquitous learning into mainstream of education and train has been the direction in the area, which demand new generational e-learning system. The paper introduces our research efforts in this direction. Based on the key concepts, such as ubiquitous learning object, mini-courseware, a new generational ubiquitous e-learning system is designed, which can be used for new requirements in m-Learning and u-Learning environments. In the system, learning resource related to a course is encapsulated into different ubiquitous learning objects, and mini-courseware can be assembled dynamically with learning resource extracted from these ubiquitous learning objects, accordingly, a mini-courseware player is designed for the situation. Based on these work, a resource based ubiquitous e-Learning system is designed considering pedagogical requirements under m-Learning and u-Learning environment

    The General Organization for Technical Education and Vocational Training, Riyadh, Saudi Arabia, has developed a special feeding program for the students at its institutions. The effects of this program on the nutritional and health status of these students have not been evaluated yet, and since no published dietary research has been performed on Technical and Vocational young adult male students, the present work was undertaken to investigate the nutritional status of this community in Riyadh, Kingdom of Saudi Arabia. After a pilot survey, it was decided to use a selfcompleted questionnaire combined with personal interview to investigate the nutritional status of 690 students randomly selected from the study population. Dietary data was collected by two methods: usual weekly intakes "diet history" and actual daily intakes "diet diary". The nutrient intakes were calculated using the unilever Dietary Analysis Program (UNIDAP). The statistical Package for the social Science (SPSS/PC+) was employed to analyse the data; statistical significance of relationships between certain sets of data was determined by chi-square analysis. Some general factors affecting the nutritional status of these students were identified, their nutritional habits and attitudes were investigated, and the average daily intakes of energy, the macronutrients, and selected micronutrients were calculated. The main results of this study shows that the majority of the study population are adolescent, moderately active individuals, and have lower than the standard range of the Body Mass Index; anaemia is the most stated health problem; meal-skipping and eating between meals are common habits amongst the students. Regarding nutrient intake, there was an energy, polyunsaturated fat, and vitamin C deficiency; adequate intake of saturated fat, dietary fibre, retinol, and zinc; more than adequate intake of protein, total fat, cholesterol, thiamin, riboflavin, calcium, and iron. Recommendations are given which aim to improve the nutrition of technical and vocational students

    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.

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
