Measuring the impact of Second Life for educational purposes

In late 2007, the following question was asked to UK academics known for developing, or teaching, in Second Life:

“I have a question. How can (if it can) the "impact" of using SL for educational purposes such as an in-world seminar or tutorial, over not using SL, be "measured" or quantified?

I'm currently a little stumped on this. For the next "snapshot", I want to focus more on the "impact". In other words, to come up with more proof or evidence that using SL has some benefits, or positive advantages, over not using SL or using some other practice.

How to do this in a form of questions has me stumped :-(”

This report brings together the set of responses that we received together with the transcript of a meeting held in Second Life to discuss the issues raised by the survey.
