Great to hear that you are working on this research paper and it is a great question to ask indeed.
Since you mention Multimedia computers with Internet connection, may I aks: What will
be the given task at hand for the learners?
Are they asked to interact with CONTENT such as learn with multi-media software (multiple choice, listening activities, drag and drop and gap fill exercises)?
Are they asked to interact with PEOPLE asynchronously (forum, blogs, discussion boards, moodle)?
Are they asked to interact with PEOPLE in real-time (virtual classroom, instant messaging, livemocha, second life etc.)?
The University of Ulster's CEMLL pages and Module 3.1 at the ICT4LT site are quite useful for advice on using multimedia labs:

This document, which I edited, may also be useful. It covers training in Section 8.
