- Using remote labs to serve different teacher's needs a case study with VISIR and RemotElectLabPublication . Fidalgo, André Vaz; Alves, Gustavo R.; Marques, Maria A.; Viegas, C.; Costa-Lobo, Cristina; Hernandez, U.; 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. And 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.
- VISIR deployment in undergraduate engineering practicesPublication . Tawfik, Mohamed; Sancristobal, Elio; Martín, Sergio; Gil, Charo; Pesquera, Alberto; Losada, Pablo; Díaz, Gabriel; Peire, Juan; Castro, Manuel; Garcia-Zúbia, Javier; Hernandez, U.; Orduña, Pablo; Angulo, Ignacio; Costa-Lobo, Cristina; Marques, Maria A.; Viegas, C.; Alves, Gustavo R.Practical sessions are the backbone of qualification in engineering education. It leads to a better understanding and allows mastering scientific concepts and theories. The lack of the availability of practical sessions at many universities and institutions owing to the cost and the unavailability of instructors the most of the time caused a significant decline in experimentation in engineering education over the last decades. Recently, with the progress of computer-based learning, remote laboratories have been proven to be the best alternative to the traditional ones, regarding to its low cost and ubiquity. Some universities have already started to deploy remote labs in their practical sessions. This contribution compiles diverse experiences based on the deployment of the remote laboratory, Virtual Instrument Systems in Reality (VISIR), on the practices of undergraduate engineering grades at various universities within the VISIR community. It aims to show the impact of its usage on engineering education concerning the assessments of students and teachers as well.
- VISIR: experiences and challengesPublication . Tawfik, Mohamed; Sancristobal, Elio; Martín, Sergio; Gil, Charo; Pesquera, Alberto; Losada, Pablo; Díaz, Gabriel; Peire, Juan; Castro, Manuel; Garcia-Zúbia, Javier; Hernandez, U.; Orduña, Pablo; Angulo, Ignacio; Costa-Lobo, Cristina; Marques, Maria A.; Viegas, C.; Alves, Gustavo R.It is of crucial importance the integration of practical sessions in engineering curricula owing to their significant role in understanding engineering concepts and scientific phenomena. However, the lack of practical sessions due to the high costs of the equipment and the unavailability of instructors has caused a significant declination in experimentation in engineering education. Remote laboratories have tackled this issues providing online reusable and shared workbenches unconstrained by neither geographical nor time considerations. Thereby, they have extremely proliferated among universities and integrated into engineering curricula over the last decade. This contribution compiles diverse experiences based on the deployment of the remote laboratory, Virtual Instrument Systems in Reality (VISIR), on the practices of undergraduate engineering grades at various universities within the VISIR community. It aims to show the impact of its usage on engineering education concerning the assessments of students and teachers as well. In addition, the paper address the next challenges and future works carried out at several universities within the VISIR community.
