4. ◌ The experiments included in the MOOC are based
on the remote laboratory platform Virtual Instrument
Systems in Reality (VISIR) a remote laboratory for
electric and electronic circuits experiments
◌ First time more than 3,000 users trying to book VISIR in
an structured way
◌ Title of the MOOC is:
◌ “Practical Basis on Circuits and Electronics” (Bases de
Circuitos y Electrónica Práctica, BCEP)

9. 2. COURSE DESIGN: PRELIMINARY
Supporting a MOOC on Electronics with VISIR
◌ The evaluation and activities go around VISIR and the objectives and
evaluation focused on the handling of instruments and measurements
◌ Even though VISIR has its own booking system, the remote laboratory
reservation system has been integrated in the platform of the MOOC
◌ The students have not time limitation for completing the different tasks
◌ All videos and activities contribute to the grading
◌ Students will get a course badge by accomplishing that the grade exceed
the cut-off grade point established (80%)
◌ All documents, guides and videos are in Spanish
◌ The main objective is the real circuits remote handling – the acquisition
of the competences for analysing circuits is not an objective

11. ◌ 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

Supporting a MOOC on Electronics with VISIR
◌ 80% points real remote laboratories are suitable tools for obtaining
practical competences
◌ 45% had experience doing real practices in a real, on-campus,
laboratory, 31% had used simulators, 9% had worked with virtual labs
and only 2% had experience with remote labs (FIRST EDITION)
◌ More than 81% enrolled the MOOC for use of a real remote laboratory
◌ More than 91% explicitly assert that real laboratory practices help a lot to
establish the relationship between theoretical contents and real behavior
◌ 43% are 36 years old or more, 33% among 26 and 35 years old and only
14% younger than 26 years old
◌ Only 11% are female
◌ 73% are from Spain, followed by 6% of Colombians
