10. STUDENTS EVALUATION
Written manual for remote experiment is clearly understandable and helpful
Remote experiment was supported by adequate explanations of teacher/teaching assistant before its starting
User interface for remote experiment within this learning module is easy to use
Response time after a user action within running experiment is satisfying
Capture of experimental results is enabled
Storage of experimental results is enabled
Quality of visual display is satisfactory
There was no problem or stalling while working with remote experiment
I would like to use remote lab in other lessons on this subject too

12. STUDENTS EVALUATION Results:
Highest grades - level of technical preparation (questions 9 – 13), performance of the equipment, quality of the user interface, ability to obtain the experimental results (questions 5 – 8)
Lowest grades - remote experiments did not help students completely in achieving learning module objectives and outcomes (questions 1 – 4)

13. STUDENTS EVALUATION Results:
Students have previously performed experiment in a laboratory in the traditional way.
Students have supported their answers with the comments on the advantages and disadvantages of this kind of experimentation

14. CONCLUSION
Remote experiments can be successfully implemented in the realization of laboratory exercises within the subject Electrical Measurements
Easy access through the Ceyeclon platform
Evaluation:
Remote experiments should be used in combination with traditional way of measurement because of the specificity of the subject
Practical knowledge from the laboratory is still primary, but better diversity of the experiments and new quality of the exercises can be achieved through the remote experiments
