Supporting a MOOC on Electronics with VISIR
◌ 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)

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
◌ 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
2. COURSE DESIGN: RESERVATIONS
Supporting a MOOC on Electronics with VISIR
◌ 42 videos◌ Handling of remote laboratory instruments and components
(R, C, D)◌ Components and circuits behavior
◌ 55 standard multiple choice questions (single and multiple-answer)
◌ 30 tests multiple choice questions◌ 4 PDF documents covering the theoretical contents of the course◌ Simulator and VISIR Manuals and Tutorials◌ Datasheets for working with real components◌ 8 Practices guides◌ Over 30 activities with sub-activities associated for experiment
with the different circuits designed

4. RESULTS: STUDENTS
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
