Changing the concept
What we teach? How we teach?

Student attitudes at the laboratory
??Your experiences?
14 October 2009 Global Colloquium on Engineering Education, Budapest 14
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”!

Importance of the task definition
• Build a vibration sensing circuit using xxx type piezoelectric accelerometer and charge amplifier. Develop measuring software suitable for continuous data acquisition and signal display. Using FFT analysis define frequency spectrum of the vibration signal.

Test and Diagnostic – the project based course
• Last semester of the study
• Team work (4 students per team)
• Team leader – the best project proposal
• Realization and presentation
• Self evaluation
14 October 2009 Global Colloquium on Engineering Education, Budapest 23
Examples from the students projects
Cooling efficiency diagnostic of different materials used for power LEDs
14 October 2009 Global Colloquium on Engineering Education, Budapest 24
Examples from the students projectsDevelopment of light intensity sensor for control of window shutter

Experiences
• Self-grouping is not successful – rearrangement
• Project proposals include too much work for the defined time limit
• Students enjoy the work (including electrical and mechanical tasks)
• Self-evaluation is mostly fair
• Half of the projects is part of the leader’s diploma work

1. Task definition – from the real life
2. Team work – learning by doing
3. Internet based system – playing-doing-learning
Motivation methods
??
14 October 2009 Global Colloquium on Engineering Education, Budapest 30
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
