Mobile Experimentation
Conclusions
•Mobile Experimentation:
• gives more benefits for engineering and sciences e-courses;
• gives more flexibility, mobility and motivation to students for running remote experiments;
• requires the use of an architecture based in a XML layer for developing versatile software applications,
beneficial for teachers and students.
