13. 14 October 2009 Global Colloquium on Engineering Education, Budapest13 Student attitudes at the laboratory ? Your experiences?

14. 14 October 2009 Global Colloquium on Engineering Education, Budapest14 Student attitudes at the laboratory 5* students „Oh. End of the seminar? Can I stay a bit?” „The neutral mass” „What is the minimum level?” „I don’t mind”! Researcher students Most of them are not able to connect or not interested in connecting the real life and the science

30. 14 October 2009 Global Colloquium on Engineering Education, Budapest30 Courses in metrology are practice oriented subjects, requiring activity and creativity of students. New practical experiments and teaching methods worked out at our department encourage students, increase their motivation. Project based course integrates theoretical knowledge and practical abilities, students solve real-life problems, while they learn to work in team. The remote controlled laboratory provides wide range of educational utilization, particular focus points depend on the specialization and the year of the study. Conclusions
