- Adaptação de Laboratórios Remotos a Cenários de Ensino: Casos de Estudo com VISIR e RemotElectLabPublication . Fidalgo, André V.; Alves, Gustavo R.; Marques, Maria A.; Viegas, Maria C.; Costa-Lobo, Maria C.; Hernández-Jayo, Unai; García-Zubía, Javier; Gustavsson, Ingvar; Alves, Gustavo; Fidalgo, André; Marques, Maria Arcelina; Viegas, Clara; Costa Lobo, Cristina; Garcia-Zubia, JavierOs laboratórios remotos são uma ferramenta tecnológica e pedagógica com uso crescente em todos os níveis de educação, e sua utilização generalizada é uma parte importante do seu próprio aperfeiçoamento e evolução. Este artigo descreve vários problemas encontrados em aulas laboratoriais, em cursos de ensino superior, na utilização de laboratórios remotos baseados em sistemas PXI, utilizando o sistema VISIR ou uma solução alternativa. São identificados e explicados três problemas que foram relatados por professores que deram apoio aos estudantes na utilização dos laboratórios remotos. O primeiro problema prende-se com a necessidade de permitir aos alunos selecionar a localização específica onde um amperímetro deve ser inserido nos circuitos elétricos, mesmo que incorreta, replicando as dificuldades do mundo real. O segundo é causado por falhas de sincronismo quando são necessárias várias medições em intervalos curtos, como no ciclo de descarga de um condensador. E o último problema é provocado pelo uso de um multímetro em modo DC na leitura de grandezas em CA, um procedimento que colide com as definições do equipamento. Todos os cenários são apresentados e discutidos, incluindo a solução encontrada para cada caso. A conclusão que se retira do trabalho descrito é que a área de laboratórios remotos é um campo em expansão, onde a sua utilização prática permite o aperfeiçoamento e a evolução das soluções disponíveis, exigindo uma cooperação e partilha de informação entre todos os intervenientes, i.e. investigadores, professores e alunos.
- Adapting remote labs to learning scenarios: case studies using VISIR and RemotElectLabPublication . Fidalgo, André Vaz; Alves, Gustavo R.; Marques, Maria A.; Viegas, C.; Costa-Lobo, Cristina; Henandez-Jayo, Unai; Garcia-Zúbia, Javier; Gustavsson, IngvarRemote laboratories are an emergent technological and pedagogical tool at all education levels, and their widespread use is an important part of their own improvement and evolution. This paper describes several issues encountered on laboratorial classes, on higher education courses, when using remote laboratories based on PXI systems, either using the VISIR system or an alternate in-house solution. Three main issues are presented and explained, all reported by teachers, that gave support to students' use of remote laboratories. The first issue deals with the need to allow students to select the actual place where an ammeter is to be inserted on electric circuits, even incorrectly, therefore emulating real-world difficulties. The second one deals with problems with timing when several measurements are required at short intervals, as in the discharge cycle of a capacitor. In addition, the last issue deals with the use of a multimeter in dc mode when reading ac values, a use that collides with the lab settings. All scenarios are presented and discussed, including the solution found for each case. The conclusion derived from the described work is that the remote laboratories area is an expanding field, where practical use leads to improvement and evolution of the available solutions, requiring a strict cooperation and information-sharing between all actors, i.e., developers, teachers, and students.
- Assessing the Remote Engineering Lab VISIR at Al-Quds University in PalestinePublication . Odeh, Salaheddin; Anabtawi, Mahasen; Alves, Gustavo R.; Gustavsson, Ingvar; Arafeh, LabibEngineering labs play a vital role in engineering education, make science come alive, and supply students with better understanding of theories. As a result, they contribute to the improvement of their knowledge and skills. Remote labs not enable sharing of teaching resources such as devices, equipment and instrumentation between universities, but also relax time and space constraints; yet they are considered as a complementary asset to the traditional hands-on labs. This paper is concerned with a two-stage assessment of the engineering remote lab VISIR. In the first stage, the assessment investigated if the students accept to use VISIR in their future lab courses at the Faculty of Engineering at Al-Quds University in Palestine. In the second stage, a deeper analysis will be performed to compare VISIR to hands-on and simulators based on the evaluation criteria: performance, students’ retention rate and satisfaction survey.
- Avaliação em Duas Fases do Laboratório Remoto em Engenharia, VISIR, na Universidade Al-Quds da PalestinaPublication . Odeh, Salaheddin; Alves, Joaquim; Alves, Gustavo R.; Anabtawi, Mahasen; Gustavsson, Ingvar; Arafeh, Labib; Jazi, Mahran; Arekat, MahmoudOs laboratórios de ciência e engenharia desempenham um papel fundamental na demonstração de conceitos e princípios, bem como na melhoria das competências técnicas. Com a introdução de laboratórios remotos foi possível partilhar dispositivos, equipamento e instrumentação entre universidades. Mais, eles evitam restrições de tempo e espaço, sendo capazes de se adaptar ao ritmo próprio de cada estudante, no caso do tempo passado no laboratório não ter sido suficiente. Neste artigo é descrito um estudo empírico, dividido em duas fases de avaliação. Na primeira fase foi avaliada a flexibilidade de aplicação do laboratório remoto em engenharia VISIR na faculdade de engenharia na Universidade de Al-Quds em Jerusalém, Palestina. Durante esta fase foi ainda avaliada a aceitação desta tecnologia, pelos estudantes, quando em interação com os laboratórios tradicionais. Na segunda fase deste estudo, que decor rerá em 2014/15, será realizada uma aprofundada análise comparativa de forma a caracterizar o VISIR perante as restantes modalidades de laboratórios de engenharia, os práticos/presenciais e os de simulação. Estas três formas de laboratório são comparadas através de testes experimentais, tendo em atenção os critérios de avaliação definidos para os laboratórios de ensino de engenharia e de acordo com os objetivos fundamentais dos cursos, nomeadamente, as taxas de retenção e de satisfação dos estudantes, bem como do seu desempenho.
- Combined efforts to develop students experimental competencesPublication . Lima, Natércia; Alves, Gustavo R.; Viegas, Clara; Gustavsson, IngvarStudents experimental competences are of most importance in engineering courses. However in post-Bologna courses, the number of contact hours and the actual extent of hands-on lab work were substantially reduced. Online resources usage (simulators and remote labs) has been growing up in the last decades, as more complex and versatile tools are being developed. Unfortunately, several of these usages reported in literature do not show the didactical backing that support these implementations. This work is a step forward, explaining how a teacher implemented a combination of online resources in order to develop experimental competences. The results show significant correlations between students’ usage of these resources and their calculus competences and final achievements.
- Do Students Really Understand the Difference Between Simulation and Remote Labs?Publication . Lima, Natércia; Viegas, Clara; Zannin, Marcelo; Marques, Arcelina; Alves, Gustavo R.; Marchisio, Susana; Lerro, Federico G.; Merendino, Claudio; Felgueiras, Carlos; Costa, Ricardo; Fidalgo, André; Silva, Juarez B. da; Pozzo, Maria; Dobboletta, Elsa; Gustavsson, Ingvar; Garcia-Peñalvo, FranciscoLaboratory experiments play a crucial role in engineering education as they strongly contribute to the development of important skills for the professional practice. This paper addresses a students’ understanding gap between simulations and remote labs. These two resources (and namely the remote laboratory VISIR - Virtual Instrument Systems in Reality) have been commonly used on several didactical implementations, along with other didactical resources in different Engineering degrees at the Federal University of Santa Catarina and Polytechnic of Porto School of Engineering. This work, developed in the scope of the VISIR+ Project, intends to evaluate students’ perceptions considering simulation and remote lab results. Quantitative and qualitative data were analyzed to better understand how deeply students realize the differences between these resources and their type of data. Preliminary results indicate that a considerable number of student’s don´t have a clear idea of these differences, even though sometimes they know their definition. Furthermore, these gap does not seem to differ much with the context (country, course, academic year, course content), students’ final grades, teacher approach or implemented tasks.
