Design of a Virtual Reality Framework for Maintainability and assemblability test of complex systems

This paper presents a unique environment whose features are able to satisfy requirements for both virtual maintenance and virtual manufacturing through the conception of original virtual reality (VR) architecture. Virtual Reality for the Maintainability and Assemblability Tests (VR_MATE) encompasses VR hardware and software and a simulation manager which allows customisation of the architecture itself as well as interfacing with a wide range of devices employed in the simulations. Two case studies are presented to illustrate VR_MATE's unique ability to allow for both maintainability tests and assembly analysis of an aircraft carriage and a railway coach cooling system respectively. The key impact of this research is the demonstration of the potentialities of using VR techniques in industry and its multiple applications despite the subjective character within the simulation. VR_MATE has been presented as a framework to support the strategic and operative objectives of companies to reduce product development time and costs whilst maintaining product quality for applications which would be too expensive to simulate and evaluate in the real world.

O uso das comunidades virtuais no ensino secundário: o caso do "Palco Virtual" ESEN-Net

A evolução do fluxo de informação e os potenciais da comunicação entre pessoas têm-se revelado deveras importante para o sucesso de diferentes organizações. A escola, enquanto organização social, apresenta uma complexidade natural própria a que se juntam todas as valências de ordem educativa, curricular e pedagógica. Tanto no âmbito educativo como organizacional, as Tecnologias de Informação e Comunicação (TIC) têm vindo a assumir um papel cada vez mais influente e imprescindível. Baseado numa metodologia de trabalho participativo e colaborativo, a construção de “palcos virtuais” resulta de uma análise de requisitos funcionais. Deste modo elabora-se um diagnóstico das necessidades de informação pela replicação das práticas diárias que podem ser quer suportadas, quer melhoradas por esta nova solução, fazendo-se um aproveitamento dos recursos físicos e humanos existentes nas escolas. A partir da iniciativa individual de um professor do grupo de informática da ESEN (Escola Secundária de Emídio Navarro – Viseu), teve início em 1999 o projecto ESEN-Net, como uma proposta de metodologia genérica para a construção de soluções baseadas em intranets para a gestão pedagógica de escolas do ensino secundário. O objectivo central deste trabalho é estudar uma comunidade que desenvolve um projecto de integração das TIC numa escola secundária, no sentido de proporcionar elementos que possam servir como contributos para melhorar a sua organização e, eventualmente, como referência para o desenvolvimento de projectos idênticos noutras escolas. A recolha de dados demonstra que a integração da TIC e o palco virtual ESEN-net veio transformar as práticas diárias na comunidade educativa através da utilização das redes telemáticas como instrumentos de ensino-aprendizagem. As TIC e o palco virtual ESEN-net vieram trazer benefícios à comunidade escolar, facilitando assim a criação e partilha de informação e contribuindo para a criação e desenvolvimento de uma comunidade virtual, onde a construção do saber pode ser feita de uma forma activa e partilhada.

'It's Almost Like Talking to a Person': Student Discolsure to Pedagogical Agents in Sensitive Setting

Online chatbots (also known as pedagogical agents or virtual assistants) are becoming embedded into the fabric of technology, both in educational and commercial settings. Yet understanding of these technologies is inchoate and often untheorised, influenced by individuals’ willingness to trust technologies, aesthetic appearance of the chatbot and technical literacy, among other factors. This paper draws upon data from two research studies that evaluated students’ experiences of using pedagogical agents in education using responsive evaluation. The findings suggest that emotional connections with pedagogical agents were intrinsic to the user’s sense of trust and therefore likely to affect levels of truthfulness and engagement. They also indicate that the topic of the pedagogical agent-student interaction is key to the student’s experience. The implications of these studies are that truthfulness, personalisation and emotional engagement are all vital components in using pedagogical agents to enhance online learning.

Interdisciplinary Pedagogical Experience for Health Human Resources Focused on the Holistic Promotion of Health and the Prevention of the Disease

The object of this experience is to offer the students the opportunity to take part in the construction of a pedagogic strategy centred on the ludic, for the promotion of the integral health and the prevention of the disease with an educational community; directed to supporting and qualifying the well-being so much individually as group. The project is designed to five years, about interdisciplinary character (Speech Therapy, Medicine, Psychology, Nursery, Occupational Therapy), interinstitutional (Universidad del Rosario, Universidad de San Buenaventura y Universidad de Cundinamarca) and intersectorial (Education and Health). It considers the different actors of the educational community and school and the home as propitious scenes for the strengthening potential, beside being the fundamental spaces for the construction of knowledges and learnings concerning the integral health. To achieve the target, one has come constructing from the second semester of 2003, one pedagogic strategy centred on the ludic and the creativity, from which they are planned, they develop and evaluate the actions of promotion of skills, values, behaviors and attitudes in the care of the health and the prevention of disease, orientated to the early, opportune and effective detection of risk factors and problematic of the development that they affect the integral health. The above mentioned strategy raises a so called scene Bienestarópolis: A healthy world for conquering, centred on prominent figures, spaces and elements that alternate between the fantasy and the reality to facilitate the approximation, the interiorización and the appropriation of the integral health. Across this one, the children motivated by the adults enter an imaginary world in that theirs desires, knowledges and attitudes are the axis of his development. Since Vigotsky raises it, in the game the child realizes actions in order to adapt to the world that surrounds it acquiring skills for the learning. The actions of the project have involved 410 children and 25 teachers, of the degrees Zero, The First and The Second of basic primary; 90 parents of family, and an average of 40 students and 8 teachers of the already mentioned disciplines.

O ensino da língua portuguesa e a linguagem na comunicação virtual: alternativas e dilemas

A presente investigação tem como objetivo compreender como os professores de Língua Portuguesa integram a linguagem da comunicação pela Internet em sua prática pedagógica, uma vez que a linguagem utilizada na comunicação virtual demonstra variações linguísticas na expectativa oposta a Língua Portuguesa em sua forma padrão e, neste contexto, a escola e o professor de português representam intermédios possíveis entre o escrito padrão e o virtual. Após processo investigativo que contou com recolha de dados documentais e entrevistas semiestruturadas, constata-se que os professores de Língua Portuguesa ressaltam as diferenças da linguagem na comunicação pela Internet em relação à forma padrão na mesma precisão em que defendem o uso da tecnologia no ambiente escolar. Afirmam que, neste contexto, o papel do professor de português concentra-se no preparo do estudante para o uso da forma padrão, permitindo uma abertura em sua prática à linguagem na comunicação virtual. Neste sentido, defendem que o posicionamento adequado do professor de Língua Portuguesa diante do ensino da língua padrão e sua relação com a linguagem virtual, centraliza-se numa abertura para um estudo linguístico na perspectiva dos possíveis usos sociais da língua, possuindo como referencial a forma padrão da Língua Portuguesa.

Virtual experts : who's online?

There will be between 30 and 80 million online students in the world by 2025. Globally, school systems are investing huge resources in the development of online education programs in order to meet this demand. Related implications for online teaching have been largely ignored despite evidence of the greatly increased workload for online teachers and widespread student dissatisfaction with online leaming experiences. Opportunities for improving the online experience for both leamers and teachers revolve around minimizing procedural inefficiencies in dealing with large numbers of individual students, as opposed to a single class, and of enhancing students' social and cognitive engagement with leaming. Intelligent software agents that can automate many routine online tasks and some aspects of leamer interaction have enormous potential to facilitate this. These agents that can act as a personal online coach, mentor or tutor to increase the individualisation of learning. The development of evidence-based agent personas is essential if agents are to fulfil specific educational roles. CUITently there is little progress being made in this area because of the lack of an agentrole model that can be used to implement specific educational personas in agents. In this paper we discuss key foundational elements of the nature and basis for implementing elements of educational expertise in software and how this could be used in developing agent persona models for specific educational roles and a model for implementing pedagogical constructs in intelligent educational software.

Crime risks of three-dimensional virtual environments

Three-dimensional virtual environments (3dves) are the new generation of digital multi-user social networking platforms. Their immersive character allows users to create a digital humanised representation or avatar, enabling a degree of virtual interaction not possible through conventional text-based internet technologies. As recent international experience demonstrates, in addition to the conventional range of cybercrimes (including economic fraud, the dissemination of child pornography and copyright violations), the 'virtual-reality' promoted by 3dves is the source of great speculation and concern over a range of specific and emerging forms of crime and harm to users. This paper provides some examples of the types of harm currently emerging in 3dves and suggests internal regulation by user groups, terms of service, or end-user licensing agreements, possibly linked to real-world criminological principles. This paper also provides some directions for future research aimed at understanding the role of Australian criminal law and the justice system more broadly in this emerging field.

The social network virtual design studio : integrated design learning using blended learning environments

Online communications, multimedia, mobile computing and face-to-face learning create blended learning environments to which some Virtual Design Studios (VDS) have reacted to. Social Networks (SN), as instruments for communication, have provided a potentially fruitful operative base for VDS. These technologies transfer communication, leadership, democratic interaction, teamwork, social engagement and responsibility away from the design tutors to the participants. The implementation of Social Network VDS (SNVDS) moved the VDS beyond its conventional realm and enabled students to develop architectural design that is embedded into a community of learners and expertise both online and offline. Problem-based learning (PBL) becomes an iterative and reflexive process facilitating deep learning. The paper discusses details of the SNVDS, its pedagogical implications to PBL, and presents how the SNVDS is successful in enabling architectural students to collaborate and communicate design proposals that integrate a variety of skills, deep learning, knowledge and construction with a rich learning experience.

Virtual design studio via social networks

With the advent of social networks, it became apparent that the social aspect of designing and learning plays a crucial role in students’ education. The ease of communication, leadership opportunity, democratic interaction, teamwork, and the sense of community are some of the aspects that are now in the centre of design interaction. Online interactions, multimedia, mobile computing and face-to-face learning create blended learning environments to which some Virtual Design Studios (VDS) have reacted. On the sample of a design studio at Deakin University the paper discusses details of the Social Network VDS, its pedagogical implications to PBL, and presents how it is successful in empowering architectural students to collaborate and communicate design proposals that integrate a variety of skills, deep learning, and construction of knowledge. It studies the effectiveness of the generated social intelligence and explores the facilitation of students’ self-directed learning. Hereby the paper studies the construction of knowledge via social interaction and how blended learning environments foster motivation and information exchange.

Preparing pre-service teachers for classroom practice in a virtual world: A pilot study using Second Life

Many pre-service teachers feel under-prepared to teach students with a diverse range of needs and abilities and continue to be concerned about classroom behaviour management when undertaking practicum experiences. In order to address these concerns, teacher educators have explored alternative pedagogical approaches, including computer based simulations and immersion in virtual worlds. This paper reports on the results of a pilot study conducted with eight pre-service teachers who operated avatars in a virtual classroom created within Second Life (SL)™. The pre-service teachers were able to role-play students with a diverse range of behaviours and engage in reflective discussion about their experiences. The results showed that the pre-service teachers appreciated the opportunity to engage in an authentic classroom experience without impacting on "real" students, but that the platform of SL proved limiting in enacting certain aspects of desired teaching pedagogy. The findings of this pilot study are discussed in relation to improving the preparation of pre-service teachers for practicum.

Using an animated pedagogical agent to interact affectively with the student

This work proposes an animated pedagogical agent that has the role of providing emotional support to the student: motivating and encouraging him, making him believe in his self-ability, and promoting a positive mood in him, which fosters learning. This careful support of the agent, its affective tactics, is expressed through emotional behaviour and encouragement messages of the lifelike character. Due to human social tendency of anthropomorphising software, we believe that a software agent can accomplish this affective role. In order to choose the adequate affective tactics, the agent should also know the student’s emotions. The proposed agent recognises the student’s emotions: joy/distress, satisfaction/disappointment, anger/gratitude, and shame, from the student’s observable behaviour, i. e. his actions in the interface of the educational system. The inference of emotions is psychologically grounded on the cognitive theory of emotions. More specifically, we use the OCC model which is based on the cognitive approach of emotion and can be computationally implemented. Due to the dynamic nature of the student’s affective information, we adopted a BDI approach to implement the affective user model and the affective diagnosis. Besides, in our work we profit from the reasoning capacity of the BDI approach in order for the agent to deduce the student’s appraisal, which allows it to infer the student’s emotions. As a case study, the proposed agent is implemented as the Mediating Agent of MACES: an educational collaborative environment modelled as a multi-agent system and pedagogically based on the sociocultural theory of Vygotsky.
