Do you think the teacher should switch roles with the students while teaching a foreign language through TIC?

There are some theories, as Pelgrum and Law (2003) suggested that it is necessary to make a switch between the teacher and the student roles. I mean, the student should be also the active role in...

I think UD has experimented with using acoustic modems. Chien-Chung Shen in CIS is an expert in that area. You have to cope very very long propagation delays. Our group is interested in these problems.

Mathieu Kemp

Mode 1: AUV surfaces and raises an RF antenna above the surface. Mode 2: a relay sits at the surface, the AUV talks to it acoustically, and the UAV over RF. Mode 2 is the most common. Typical relays are a gateway buoy, or a waveglider.

Hi Victor,

There are some solutions with directive lasers. High communication bandwidth van be achieved, but the positionnement precision , and stability of the station keeping requirements are important.
