- Automatic assessment using VISIR-DBPublication . Hernandez-jayo, Unai; Garcia-Zubia, Javier; Cuadros, Jordi; Serrano, Vanessa; Fernandez-Ruano, Laura; Alves, GustavoVISIR is a remote laboratory oriented to analogue electronics. There are several copies of VISIR around the world (Sweden, Spain, Portugal, Costa Rica, Brazil, Argentina, India, Australia, Morocco, …) that are being used by thousands of students. It is well known that VISIR allows teachers and students to create and measure real electrical and electronics circuits through a useful interface and a complex hardware & software platform. But at this moment there is not available at the interface neither offline, any feedback from the VISIR to teachers/students about the performance of the user during the experimentation. This article pre sents the use of the VISIR Dashboard (VISIR-DB) that the teacher can perform to know the achievement of his students using the VISIR remote laboratory.
- Classification of Experimental Errors Done in VISIR with Simple Alternated Current CircuitsPublication . Mendonca, Lucas Nascimento; Macaneiro, Mayara; Alves, Gustavo R.; Pires, Danubia Soares; Garcia-Zumbia, Javier; Cuadros, Jordi; Serrano, VanessaDuring experiments with electric circuits, students often make mistakes. To handle these situations, remote laboratories such as VISIR (Virtual Instruments Systems in Reality) rely on error-handling mechanisms, which do not always cover all errors. This article seeks to extend a previously published work when trying to assimilate all possible errors in alternated current circuits with a single power supply and a single passive component. The goal is to build an errors’ map with all possible errors, covering all circuits that can be assembled in VISIR, from the simplest to the most complex. This allows limiting misconceptions during theoretical and practical understanding are limited.
- Dashboard for the VISIR remote labPublication . Garcia-Zubia, Javier; Cuadros, Jordi; Serrano, Vanessa; Hernandez-Jayo, Unai; Angulo-Martinez, Ignacio; Villar, Aitor; Orduna, Pablo; Alves, Gustavo R.The VISIR dashboard (VISIR-DB) is a learning analytics tool connected with the VISIR remote lab. In VISIR, every action performed by a student from the interface over the remote laboratory and back is logged and recorded. VISIR-DB helps visualizing, in a fast and deep way, the recorded logs from this communication. Using this tool, a teacher can analyze and understand better how the students are using the remote lab during their learning process on analog electronics. With this information, the VISIR platform can be improved and the use of remote labs can be better understood.
- A framework for interpreting experimental errors in VISIRPublication . Garcia-Zubia, Javier; Alves, Gustavo R.; Hernandez-Jayo, Unai; Cuadros, Jordi; Serrano, Vanessa; Fidalgo, AndréStudents usually do errors while performing experiments. In traditional, hands-on labs, instructors are able to help students surpass those errors. In non-traditional labs, like virtual labs or simulations, the support is usually provided by built-in mechanisms that prevent erroneous actions or that provide some sort of online assistance. In remote labs, like the Virtual Instruments Systems in Reality (VISIR) remote lab, the same principle applies. This paper describes the very initial stage of a framework for interpreting experimental errors done in VISIR. It considers the course syllabus of electrical circuits and situates the work done till the moment, in relation to that syllabus. Future work is also addressed.
- Using VISIR Remote Lab in the Classroom: Case of Study of the University of Deusto 2009-2019Publication . García-Zubía, Javier; Cuadros, Jordi; Hernández-Jayo, Unai; Serrano, Vanessa; Angulo, Ignacio; Alves, Gustavo R.; Fidalgo, AndréDuring the last ten years, the University of Deusto is using VISIR remote lab for analog electronics in the Faculty of Engineering. Present paper shows how we are using the VISIR with students, and its results. It is a catalog of experiments to invite other universities to join the VISIR consortium. Ongoing and future research in VISIR are also presented
