STUDENTS’ EVALUATION -10 undergraduate students students from master course in Remote Control -Questionnaire -First part - 15 questions -Second part - essay questions: advantages and disadvantages TREND 2016 Conference , Zlatibor

STUDENTS’ EVALUATION 1.Conducting of this remote experiment helped me to achieve learning module's objectives 2.Conducting of this remote experiment helped me to achieve learning module's outcomes 3.The remote experiment facilitated better understanding of module's theoretical background 4.The remote experiment helped mi to learn to use lab equipment 5.Remote experiment within this learning module is prepared on appropriate technical level 6.Experiment is easy to understand and use TREND 2016 Conference , Zlatibor

STUDENTS’ EVALUATION 7.Written manual for remote experiment is clearly understandable and helpful 8.Remote experiment was supported by adequate explanations of teacher/teaching assistant before its starting 9.User interface for remote experiment within this learning module is easy to use 10.Response time after user action within running experiment is satisfying 11.Capture of experimental results is enabled 12.Storage of experimental results is enabled 13.Quality of visual display is satisfactory 14.There was no problem or stalling while working with remote experiment 15.I would like to use remote lab in other lessons of this subject too TREND 2016 Conference , Zlatibor

STUDENTS’ EVALUATION TREND 2016 Conference , Zlatibor Question Not relevant Average grade

STUDENTS’ EVALUATION Results First part: Highest grades : adequate support from teacher/teaching assistant easiness of usage and understanding understandability and helpfulness of the written manual preparation of remote experiment in technical point of view Lowest grades response time problems - stalling during work on the remote experiment TREND 2016 Conference , Zlatibor

STUDENTS’ EVALUATION Results Second part: Biggest disadvantages: very slow response time camera which could not be integrated in the application for a while Advantages: they can do experiment from home, process was easy to understand, experiment help them in understanding of some theoretical concepts TREND 2016 Conference , Zlatibor

CONCLUSI ON By using described experiment students have opportunity to control remotely stepper motor by changing the parameters in the application. Easy implementation and use of CEyeClon platform Evaluation process – improvement of lab module for the following generations of students TREND 2016 Conference , Zlatibor
