Introduction

Technology:– is the major change factor of society;– improves people’s lives;– gives flexibility to access knowledge;– incentives developing new applications for the teaching/learning process.

Time Line: technology vs educational concepts:

is the local access to educational resources using PCs

is the Web access to educational resources using PCs, supported by Virtual Learning Environments is the Web access to remote

experiments in sciences and engineering using PCs

is the wireless network access to educationalresources using mobile devices

is the wireless network access to remote experiments using mobile devices

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.
