- 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.
- Design state exploration applied to the development of a remote lab for projectile launch experimentsPublication . Alves, Gustavo R.; Marques, Maria A.; Paiva, Carlos; Nogueira, Pedro; Guimarães, P. S.; Couto, Ruben; Cherem, Laryssa; Borba, Vitor; Ferreira, Golberi; Koch, Stefan; Pester, AndreasThis paper describes the application of Design State Exploration techniques in the development of a remote lab for projectile motion experiments. The application was enabled by the existence of two independent teams: one composed of a series of internships that started first and another with two grantees that started a few months later. The paper presents evidence on how this approach provided gains in the development process conducted by the second team that benefited from design state exploration studies performed by the first team. This particular aspect is highlighted in relation to the work already presented in the 10th Remote Engineering and Virtual Instrumentation (REV) conference.
- Diferentes Integrações de Laboratórios Remotos em Cursos de EngenhariaPublication . Costa-Lobo, Cristina; Viegas, Clara; Alves, Gustavo R.; Marques, Maria A.Este artigo aborda diferentes integrações do VISIR. O VISIR é um laboratório aberto remoto dedicado a experimentos com circuitos elétricos e eletrónicos. Este laboratório permite que professores e alunos tenham oportunidade de contatar com experimentos remotamente e em tempo real, com equipamentos de teste e medição (fonte de alimentação tripla DC, gerador de funções, multímetro e um osciloscópio) ligado a componentes elétricos e eletrónicos. As abordagens didáticas são resumidas e as análises feitas fornecem explicações para alguns dos problemas encontrados, além de algumas diretrizes para futuras implementações. Uma série de pontos fortes e fracos é destacada, levando a sugestões sobre como aprimorar algumas abordagens estratégicas para motivar professores e motivar alunos para o potencial da utilização do VISIR no ensino e na aprendizagem. São apresentadas referências apropriadas para trabalhos publicados anteriormente que ajudam a entender o contexto de pesquisa e as lições derivadas de um uso mais intensivo do VISIR.
- Engaging students by moodleing a course? Case studies at the Polytechnic of Porto–School of EngineeringPublication . Viegas, C.; Marques, Maria A.; Alves, Gustavo R.; Costa-Lobo, CristinaThis work presents a comparative study covering four different courses lectured at the Polytechnic of Porto - School of Engineering, regarding the usage of a particular Learning Management System, i.e. Moodle, and its impact on students' results. This study addresses teachers who used this platform as a complement to their courses (b-learning) and identifies some particular issues in order to potentiate students' engagement and learning. Even though positive correlation factors exist, e.g. between the number of Moodle accesses versus the final exam grade obtained by each student, the explanation behind it may not be straightforward. Mapping this particular factor to course numbers reveals that the quality of the resources might be preponderant and not only their quantity. These results point to the fact that some dynamic resources might enlarge students' engagement.

- A flexible online apparatus for projectile launch experimentsPublication . Paiva, Carlos; Nogueira, Pedro; Alves, Gustavo R.; Marques, Maria A.; Guimarães, P. S.; Couto, RubenIn order to provide a more flexible learning environment in physics, the developed projectile launch apparatus enables students to determine the acceleration of gravity and the dependence of a set of parameters in the projectile movement. This apparatus is remotely operated and accessed via web, by first scheduling an access time slot. This machine has a number of configuration parameters that support different learning scenarios with different complexities.
- How Remote Labs Impact on Course Outcomes: Various Practices Using VISIRPublication . Marques, Maria A.; Viegas, Maria Clara; Costa-Lobo, Maria Cristina; Fidalgo, André Vaz; Alves, Gustavo R.; Rocha, Joao S.; Gustavsson, IngvarAs technology is increasingly being seen as a fa- cilitator to learning, open remote laboratories are increasingly available and in widespread use around the world. They provide some advantages over traditional hands-on labs or simulations. This paper presents the results of integrating the open remote laboratory VISIR into several courses, in various contexts and using various methodologies. These integrations, all related to higher education engineering, were designed by teachers with different perspectives to achieve a range of learning outcomes. The degree to which these VISIR-related outcomes were accomplished is discussed. The results reect the levels of student engagement and learning and of teacher involvement. From the analysis, a connection between these two aspects was traced, although only related to the user proles. VISIR is shown to be always of benet for more motivated students, but this benet can be maximized under particular conditions and characteristics.

- Impact of different moodle course designs on students? PerformancePublication . Alves, Gustavo R.; Viegas, C.; Marques, Maria A.; Costa-Lobo, Cristina; Silva, António A.; Formanski, Francieli; Silva, Juarez Bento daThis work describes the impact of different teachers’ approaches in using Moodle, for supporting their courses, at the Polytechnic of Porto - School of Engineering. The study covers five different courses, from different degrees and different years, and includes a number of Moodle resources especially supporting laboratory classes. These and other active resources are particularly analyzed in order to evaluate students’ adherence to them. One particular course includes a number of remote experiments, made available through VISIR (Virtual Instrument Systems in Reality) and directly accessible through links included in the Moodle course page. The collected data have been correlated with students’ classifications in the lab component and in the exam, each one weighting 50% of their final marks. This analysis benefited from the existence of different teachers’ approaches, which resulted in a diversity of Moodle-supported environments. Conclusions point to the existence of a positive correlation factor between the number of Moodle accesses and the final exam grade, although the quality of the resources made available by the teachers seems to be preponderant over its quantity. In addition, different students perspectives were found regarding active resources: while some seem to encourage students to participate (for instance online quiz or online reports), others, more demanding, are unable to stimulate the majority of them.
