inVídeo: uma aplicação de vídeo interactivo sobre a Internet

A utilização de vídeo e áudio sobre a Internet tem ganho nos últimos anos um interesse crescente. Na verdade, o interesse não é recente, mas os limites tecnológicos de variadíssimas ordens impediam o desenvolvimento e a utilização alargada de aplicações com media ricos. Os avanços nas tecnologias relacionadas com, por exemplo, a compressão, as redes e as ferramentas multimédia possibilitaram o desenvolvimento e o funcionamento, de uma forma alargada, de sistemas multimédia. O trabalho apresentado nesta dissertação descreve a especificação e a implementação de um sistema de formação à distância, designado inVídeo, que utiliza o vídeo como elemento central. O sistema tem como objectivo proporcionar formação por intermédio de uma aplicação que permite a visualização paralela de um vídeo com imagens ou animações, acompanhada com outros dados, como texto e acesso a ficheiros que podem ser descarregados. O enquadramento para esta aplicação surgiu das necessidades de formação contínua de um centro hospitalar, todavia a aplicação foi desenvolvida para poder ser utilizada noutras instituições. A especificação passou pela descrição do problema e sua modelação utilizando um método para o desenvolvimento de aplicações interactivas, o WISDOM. A implementação descreve o sistema desenvolvido, a justificação das opções tecnológicas e os resultados de um inquérito feito aos utilizadores do sistema. O desenvolvimento do sistema levou ao estudo e, em alguns casos, à utilização de um conjunto de tecnologias distintas. Os estudos iniciais abordaram as tecnologias que possibilitam a utilização do vídeo sobre a Internet e algumas das suas condicionantes. Seguiram-se a composição, sincronização e interactividade multimédia, e por fim o uso de metadados para conteúdos educacionais. A resposta dada pelos utilizadores durante a utilização do sistema foi bastante satisfatória e revelou um grande interesse no uso do vídeo sobre a Internet. A construção de aplicações para Internet utilizando media exigentes deixou de ser a tarefa complexa que era há alguns anos, isto devido aos avanços tecnológicos. Todavia o desenvolvimento ainda necessita de muita ponderação e do enquadramento de muitos factores relacionados com a codificação dos media e com a heterogeneidade das redes, dos utilizadores e dos equipamentos.

Depleting the curriculum: teaching digital platforms and curricular impoverishment

The paper aims at showing how curricular complexity tends to be depleted by the use of digital platforms based on the SCORM (Sharable Content Object Reference Model) standard, which was created with the main purpose of recycling content as it is supposed to be independent both from the context of learning and the supporting technology also deemed to be neutral, all surrounded by a rhetoric of innovation and “pedagogical” innovation. The starting point of the discussion is García Perez’s model of Traditional Didactics as a simple tool to show almost graphically that any ancient didactic model is far richer in terms of complexity than the linearity, in disguise most of the times but still visible under a not so sophisticated critical lens, of the interaction human-(reusable) content that is the basis of the SCORM standard. The paper also addresses some of the more common deliberate mix-ups related to those digital platforms, such as learning and teaching, content and learning object, systems of automatic teaching and learning management systems.

Rich media content adaptation in e-learning systems

The wide use of e-technologies represents a great opportunity for underserved segments of the population, especially with the aim of reintegrating excluded individuals back into society through education. This is particularly true for people with different types of disabilities who may have difficulties while attending traditional on-site learning programs that are typically based on printed learning resources. The creation and provision of accessible e-learning contents may therefore become a key factor in enabling people with different access needs to enjoy quality learning experiences and services. Another e-learning challenge is represented by m-learning (which stands for mobile learning), which is emerging as a consequence of mobile terminals diffusion and provides the opportunity to browse didactical materials everywhere, outside places that are traditionally devoted to education. Both such situations share the need to access materials in limited conditions and collide with the growing use of rich media in didactical contents, which are designed to be enjoyed without any restriction. Nowadays, Web-based teaching makes great use of multimedia technologies, ranging from Flash animations to prerecorded video-lectures. Rich media in e-learning can offer significant potential in enhancing the learning environment, through helping to increase access to education, enhance the learning experience and support multiple learning styles. Moreover, they can often be used to improve the structure of Web-based courses. These highly variegated and structured contents may significantly improve the quality and the effectiveness of educational activities for learners. For example, rich media contents allow us to describe complex concepts and process flows. Audio and video elements may be utilized to add a “human touch” to distance-learning courses. Finally, real lectures may be recorded and distributed to integrate or enrich on line materials. A confirmation of the advantages of these approaches can be seen in the exponential growth of video-lecture availability on the net, due to the ease of recording and delivering activities which take place in a traditional classroom. Furthermore, the wide use of assistive technologies for learners with disabilities injects new life into e-learning systems. E-learning allows distance and flexible educational activities, thus helping disabled learners to access resources which would otherwise present significant barriers for them. For instance, students with visual impairments have difficulties in reading traditional visual materials, deaf learners have trouble in following traditional (spoken) lectures, people with motion disabilities have problems in attending on-site programs. As already mentioned, the use of wireless technologies and pervasive computing may really enhance the educational learner experience by offering mobile e-learning services that can be accessed by handheld devices. This new paradigm of educational content distribution maximizes the benefits for learners since it enables users to overcome constraints imposed by the surrounding environment. While certainly helpful for users without disabilities, we believe that the use of newmobile technologies may also become a fundamental tool for impaired learners, since it frees them from sitting in front of a PC. In this way, educational activities can be enjoyed by all the users, without hindrance, thus increasing the social inclusion of non-typical learners. While the provision of fully accessible and portable video-lectures may be extremely useful for students, it is widely recognized that structuring and managing rich media contents for mobile learning services are complex and expensive tasks. Indeed, major difficulties originate from the basic need to provide a textual equivalent for each media resource composing a rich media Learning Object (LO). Moreover, tests need to be carried out to establish whether a given LO is fully accessible to all kinds of learners. Unfortunately, both these tasks are truly time-consuming processes, depending on the type of contents the teacher is writing and on the authoring tool he/she is using. Due to these difficulties, online LOs are often distributed as partially accessible or totally inaccessible content. Bearing this in mind, this thesis aims to discuss the key issues of a system we have developed to deliver accessible, customized or nomadic learning experiences to learners with different access needs and skills. To reduce the risk of excluding users with particular access capabilities, our system exploits Learning Objects (LOs) which are dynamically adapted and transcoded based on the specific needs of non-typical users and on the barriers that they can encounter in the environment. The basic idea is to dynamically adapt contents, by selecting them from a set of media resources packaged in SCORM-compliant LOs and stored in a self-adapting format. The system schedules and orchestrates a set of transcoding processes based on specific learner needs, so as to produce a customized LO that can be fully enjoyed by any (impaired or mobile) student.

CyberAula 2.0: Integration of Moodle with videoconferencing and lecture recording services.

This paper describes the CyberAula 2.0 project which presents an integrated solution for videoconferencing and lecture recording as a mechanism to support subjects which need to be promoted or discontinued within the framework of the European convergence process. Our solution is made up of a web portal, a videoconferencing tool and an economical and easily transportable hardware kit. Recording sessions can be exported to SCORM and LOM compliant files which can be imported by an LMS. The validation process is currently being carried out in five scenarios at our university that use Moodle as a way to deliver content to students.

Facilitating the creation of interactive multi-device Learning Objects using an online authoring tool

Learning Objects facilitate reuse leading to cost and time savings as well as to the enhancement of the quality of educational resources. However, teachers find it difficult to create or to find high quality Learning Objects, and the ones they find need to be customized. Teachers can overcome this problem using suitable authoring systems that enable them to create high quality Learning Objects with little effort. This paper presents an open source online e-Learning authoring tool called ViSH Editor together with four novel interactive Learning Objects that can be created with it: Flashcards, Virtual Tours, Enriched Videos and Interactive Presentations. All these Learning Objects are created as web applications, which can be accessed via mobile devices. Besides, they can be exported to SCORM including their metadata in IEEE LOM format. All of them are described in the paper including an example of each. This approach for creating Learning Objects was validated through two evaluations: a survey among authors and a formal quality evaluation of 209 Learning Objects created with the tool. The results show that ViSH Editor facilitates educators the creation of high quality Learning Objects.

Aplicación Android para el aprendizaje de inglés nivel B2 : extensión del ILLLab

Desde el inicio de la globalización, el aprendizaje de la lengua inglesa se ha instaurado como una necesidad. Hoy en día, con la adopción del Espacio Europeo de Educación Superior este lenguaje no sólo se impone como un requisito para los estudiantes sino que se exige un nivel B2, lo cual significa un esfuerzo mayor tanto como para el alumno como para el profesor a la hora de hacer de este ejercicio un hábito y lograr la evaluación continua de los mismos. Este proyecto intenta extender las funcionalidades de una aplicación existente llamada Illlab con ejercicios que se adapten al nivel B2 y permitan la interacción entre alumnos durante la realización de estos ejercicios. El objetivo de esta aplicación es el de desarrollar ejercicios extra en la aplicación Illlab que añadan complejidad para el aprendizaje de inglés de un nivel B2 y que además se puedan realizar actividades entre los alumnos. La idea es hacer una aplicación de preguntas y respuestas “multiple choice” con cuatro opciones por pregunta. El fuerte de este juego está en presentar material variado sobre uso de la lengua y además permitir el juego entre varios alumnos. La extensión de ILLLab se plantea como un proyecto para desarrollar interfaces y funcionalidades adicionales en la antigua aplicación. La principal funcionalidad que se añade es un juego de preguntas y respuestas con opciones múltiples para un nivel B2 y las interfaces responden a necesidades de intercambio y manejo de contenido por Internet mediante estándares aceptados en el mundo del aprendizaje digital tales como Common Cartridge o SCORM. Este proyecto simplemente adapta la aplicación para su uso en un entorno de evaluación de actividades en el cual el profesor tiene acceso a las actividades que realizan los alumnos de un curso para su posterior evaluación. Antiguamente ILLLab sólo contenía ejercicios que se llevaban a cabo en el dispositivo móvil por lo que el control de estas actividades no era posible. La mejora se presenta como una interfaz Common Cartridge para el manejo del contenido, una interfaz de comunicación sobre servicios web tipo REST y el manejo de base de datos mediante Hibernate que agrupa una serie de librerías Java para la persistencia de objetos de la base de datos. ABSTRACT. Since the onset of globalization, the learning of the English language has become as a necessity. Today, with the adoption of the European Higher Education Area this language is not only imposed as a requirement for students but a B2 level is required, which means a greater effort both to the student and teacher when it comes to make the learning exercise a habit and achieve continuous evaluation of students. This project aims to extend the functionality of an existing application called Illlab with an exercise that suits the B2 level and allow interaction between students while performing these exercises. The purpose of this application is to develop an additional exercise in the application Illlab that adds complexity for learning English at B2 level and also enables the interaction among students. The main idea is to make an application in multiple choices style with four options. The strength of this game is to present varied material on use of Enlgish and also allow play between two students. ILLLab extension is conceived as a project to develop interfaces and additional functionalities in the old application. The main functionalities added are a game of questions and answers with multiple choices for a B2 level and interfaces that meet information exchange requirements and content management over the Internet using standards adopted in the world of digital learning such as Common Cartridge or SCORM. This project simply adapts the application for its use in an activities evaluation environment in which the teacher has access to the activities performed by students in a course for further evaluation. The former versión of ILLLab contained only exercises that were carried out on the mobile device so that the evaluation of these activities was not possible. The improvement comes as a Common Cartridge interface for content management, a communication interface with REST web services and a database access using Hibernate which groups a number of Java libraries for object persistence in the database.

Diseño de itinerarios de aprendizaje sobre Moodle para asignaturas de redes de computadores basados en virtualización mediante software libre

El diseño de recursos educacionales y materiales didácticos vía on-line permite mejorar el aprendizaje autónomo y a distancia (o no presencial). El proceso de convergencia Europea del Espacio de Educación Superior determina que el empleo de este tipo de recursos dota al estudiante de más flexibilidad, aunque la metodología de educación dominante sea la tradicional (es decir, las clases presenciales). Los recursos educacionales on-line juegan un rol importante en este contexto. En trabajos previos se ha experimentado diseñando cursos con ayuda de un LCMS (Learning Content Management System) como el Moodle corporativo de la UA, incorporando documentos SCORM para diseñar lecciones de autoevaluación, con laboratorios virtuales y otras herramientas de simulación de diseño propio (KIVANS, applets KIVANS+EJS). En esta nueva red se pretende generar nuevos recursos didácticos basados en software libre. Ninguno de los laboratorios virtuales desarrollados hasta ahora permiten a los alumnos poner en práctica los desarrollos de las clases presenciales a distancia. Para ello, usando el software de libre distribución GNS3, y teniendo como base la configuración de la red del laboratorio L24 de la EPS, se pretende construir un entorno virtual que simule las posibilidades reales de este laboratorio.
