Using the internet as a tool shows only one thing...you know how to use the internet.
If that is the skill you are testing then all well and good.
But to have learned something means that there has to be an observable change in behaviour, which can be attributed to something that has been taught....or certainly that was what I was lead to believe in my CGLI Adult Education Cert.
I honestly can't say that the internet would fulfil that criteria......you still interaction with teachers...you can be a long way down the wrong road if you have no-one supervising what you are doing.
