Abstract: Context: Recent advances in technology allow for many improvements in educational practices. In particular, virtual laboratories can be very useful in the teaching of the engineering subjects. The existing publications claim several advantages of virtual laboratories: they provide experimentation relevant to the real world events at a fraction of cost, allow for an increase in the number of students that can perform otherwise costly or complex experiments, and effectively substitute potentially dangerous or hazardous experiments. On the other hand, the problems relating to virtual laboratories include a potentially high cost of specialized software and hardware, a need in additional physical space and technical personnel, and a need in additional technical and financial resources. Therefore, the educational efficiency of virtual laboratories depends strongly on the intelligent design of particular virtual exercises and the balance between the virtual and hands-on exercises or experiments. We faced these considerations while trying to improve the quality of the students' learning of the content of the undergraduate optional Quantum Devices course at our University.
Purpose: The purpose of the present work was to verify the possibility of improving the quality of the students' learning of the content of the undergraduate Quantum Devices course by establishing new teaching laboratories with complementary virtual and hands-on experiments.
Approach: We analysed the state of art of the Optical Spectrometry, as well as the Telecommunications Industry requirements for our graduates. We developed the content of virtual and hands-on Optical Spectrometry laboratory and designed complimentary virtual and hands-on experiments taking into account the aforementioned data.
Results: The complimentary nature of virtual and hands-on experiments allowed our students to learn the theoretical aspects and measurement methods, instruments and procedures of the Optical Spectroscopy that are important in industrial and scientific research applications. Also, the students acquired a wider, panoramic knowledge of the spectrometric methods and techniques and their applications in comparison to the laboratory with only hands-on experiment.
Conclusions: We designed, implemented and evaluated the educational efficiency of the Optical Spectrometry laboratory, which comprised virtual exercises and complimentary hands-on experiments. Our results show that students benefit from such a laboratory, in contrast to only hands-on teaching laboratory.
