- Academic effectiveness of VISIR remote lab in analog electronicsPublication . Garcia-Zúbia, Javier; Henandez-Jayo, Unai; Gustavsson, Ingvar; Alves, Gustavo R.The effectiveness of VISIR is compared to other experimentation activities under the point of view presented by the professor Soysal in 2000. Advantages and limitations are discussed in terms of equipment availability, infrastructure cost, and contribution to various elements of experimental learning.
- 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.
- Peers' evaluation of a reconfigurable IEEE1451.0-compliant and FPGA-based weblabPublication . Costa, Ricardo J.; Alves, Gustavo R.; Zenha-Rela, Mário; Zutin, D. G.; Zackrisson, J.; Rochadel, Willian; Henandez-Jayo, UnaiIt is already more than 10 years that weblabs are seen as important resources to provide the experimental work required in engineering education. Several weblabs have been applied in engineering courses, but there are still unsolved problems related to the development of their infrastructures. For solving some of those problems, it was implemented a weblab with a reconfigurable infrastructure compliant with the IEEE1451.0 Std. and supported by Field Programmable Gate Array (FPGA) technology. This paper presents the referred weblab, and provides and analyses a set of researchers' opinions about the implemented infrastructure, and the adopted methodology for the conduction of real experiments.
