The document discusses a MOOC on electronics supported by Manuel Castro, featuring a remote laboratory platform called VISIR for practical experiments. It outlines the course design, objectives, and results from three editions, highlighting user engagement and the integration of real laboratory practices in online education. Key findings reveal the effectiveness of remote labs in enhancing students' practical competencies in electronics.
![◌ VISIR collide with one of the most relevant features that any
MOOC should achieve: scalability [16]
◌ Initial settings:
◌ 16 simultaneous users
◌ 60 minutes per turn
◌ 2 simultaneous turns booked
◌ 14 turns per course
◌ With these settings, up to 384 students every day
◌ Adjusting these parameters, the administrators are able to
regulate remote laboratory availability to the demand of use
