- Analog electronic teaching – a new approach for bipolar transistorsPublication . Felgueiras, Carlos; Santos, Catarina; Alves, Gustavo R.; Fidalgo, André; Pertry, Clovis; Schlichting, Luisa) This work was based in a single individual sample; b) Learning Support Means (LSM) received poor acceptance; c) Other Alternative Support Means are under development; d) For these, a broader test sample was used; e) Preliminary results from this test are encouraging to further pursue this work
- Aspectos de Diferenciação entre Laboratórios Remotos e SimuladoresPublication . Branco, Matheus; Coelho, Letícia A.; Alves, Gustavo R.; Schlichting, LuisOs laboratórios remotos surgiram como apoio para o desenvolvimento de novos métodos de aprendizagem e ainda como suporte adicional a métodos já existentes. Ágeis e acessíveis aos estudantes demonstram ótimas soluções no cenário da educação, sendo econômicos e dinâmicos, pois possuem acesso mundial por plataformas criadas a partir da tecnologia da informação, disponibilizando a otimização do hardware com usuários remotamente distribuídos. Os laboratórios remotos dinamizam o aprendizado fazendo o mesmo mais eficiente. Facilitam e possibilitam a capacidade analítica pela percepção de diferentes resultados entre laboratórios virtuais (simuladores) e laboratórios reais por apresentarem resultados reais em circuitos com influências externas como térmica, elétrica, magnética ou eletromagnética e principalmente apresentam as não idealidades (capacitâncias, resistências e indutâncias intrínsecas) relacionadas aos aspectos construtivos de componentes eletrônicos (resistores, indutores, capacitores, trilhas e fios). Assim, este artigo propõe demonstrar por meio de experimentações práticas as diferenciações entre dados obtidos através do laboratório remoto VISIR e os simuladores PSIM e PROTEUS sendo possível verificar dados reais em experiências com circuitos que apresentam não idealidades.
- Differentiating simulations and real (remote) experimentsPublication . Varela, Matheus; Coelho, Letícia; Schlichting, Luis; Alves, Gustavo R.The more recent emergence of remote laboratories caused some discussions about their real educational value, when compared to traditional hands-on and virtual laboratories. This discussion is relevant because remote labs rely on computer-mediated access to real instruments and apparatus, being sometimes difficult to explain the difference between values obtained from real (remote) measurements and values obtained from computer simulations. This paper aims to evidence aspects that differentiate remote and virtual laboratories, by presenting two very simple experiments dealing with the characteristics of real instruments (limited bandwidth) and real circuits (electromagnetic interference).
- Spreading remote lab usage: A system — A community — A FederationPublication . Alves, Gustavo R.; Fidalgo, André Vaz; Marques, Arcelina; Viegas, Clara; Felgueiras, Carlos; Costa, Ricardo; Lima, Natercia; Castro, Manuel; Diaz-Orueta, Gabriel; Ruiz, Elio San Cristobal; Garcia-Loro, Felix; Garcia-Zubia, Javier; Hernandez-Jayo, Unai; Kulesza, Wlodek; Gustavsson, Ingvar; Pester, Andreas; Zutin, Danilo; Schlichting, Luis; Ferreira, Golberi; Bona, Daniel Dezan de; Silva, Juarez B. da; Alves, Joao B.; Bilessimo, Simone; Pavani, Ana; Lima, Delberis; Temporao, Guilherme; Marchisio, Susana; Concari, Sonia; Lerro, Federico; Fernandez, Ruben; Paz, Hector; Soria, Fernando; Almeida, Nival; Oliveira, Vanderli de; Pozzo, Maria I.; Dobboletta, ElsaExperiments have been at the heart of scientific development and education for centuries. From the outburst of Information and Communication Technologies, virtual and remote labs have added to hands-on labs a new conception of practical experience, especially in Science, Technology, Engineering and Mathematics education. This paper aims at describing the features of a remote lab named Virtual Instruments System in Reality, embedded in a community of practice and forming the spearhead of a federation of remote labs. More particularly, it discusses the advantages and disadvantages of remote labs over virtual labs as regards to scalability constraints and development and maintenance costs. Finally, it describes an actual implementation in an international community of practice of engineering schools forming the embryo of a first world wide federation of Virtual Instruments System in Reality nodes, under the framework of a project funded by the Erasmus+ Program.
- The VISIR Implementation Process at IFSC - problems, obstacles and solutionsPublication . Schlichting, Luis; Bona, Daniel de; Ferreira, Golberi; Alves, Gustavo R.In recent year, the use of remote laboratories applied to teaching has been more frequent in several educational institutions around the world. The benefits on the learning process are easy to verify. In addition, remote laboratories bring in their application, operational advantages associated to component inventory, equipment maintenance, security, and others practical issues. Considering this, it is intuitive that the implantation of a remote laboratory and its use is easily recognized and accepted by the users, namely, students and teachers. This paper aims to present the obstacles and advantages observed in the implantation of the virtual laboratory VISIR (Virtual Instruments Systems in Reality) at Federal Institute of Santa Catarina - IFSC, as well as the obtained results.
- Using a 3-tier Training Model for Effective Exchange of Good Practices in as ERASMUS+ ProjectPublication . Alves, Gustavo R.; Fidalgo, André; Marques, Maria A.; Viegas, Clara; Felgueiras, Carlos; Costa, Ricardo J.; Lima, Natércia; Kulesza, Wlodek; García-Zubía, Javier; Castro, Manuel; Pester, Andreas; Pavani, Ana; Silva, Juarez B. da; Schlichting, Luis; Marchisio, Susana; Fernández, Ruben; Oliveira, Vanderli F. de; Pozzo, María I.VISIR+ is an Erasmus+ project that aims to develop educational modules for electric and electronic circuits theory and practice following an enquiry-based teaching and learning methodology. The project has installed five new VISIR remote labs in Higher Education Institutions located in Argentina and Brazil, to allow students doing more experiments and hence acquire better experimental skills, through a combination of traditional (hands-on), remote and virtual laboratories. A key aspect for the success of this project was to motivate and train teachers in the underpinning educational methodology. As such, VISIR+ adopted a 3-tier training process to effectively support the use of VISIR in the Institutions that received it. This process is based on the “train the trainer” approach, which required the participating partner institutions to identify and engage a number of associated partners, interested in using their newly installed remote lab. To measure the quality of the training process, the same satisfaction questionnaire was used in all training actions. This paper presents a detailed description of the training actions along with the analysis of the satisfaction questionnaire results. Major conclusions are that the quality level of the training process remained practically the same across all training actions and that trainees sometimes considered the practical use of the VISIR remote lab as difficult, irrespectively of where and when the training action took place.
