In Alderson's article, he talks about how the use of IT for language testing is begining to emerge into this mulitimedia world. More and more tests are carried out using cd-roms, students can now learn and be assessed just by using the computer, this is most popular for distance learning students. I think one advantage of this is that it can accomodate many people's busy schedules, they can be assessed and complete assignments just by using their own computer which can save a lot of time. The downside of it is that it is hard to speak to classmates or even your teacher face to face. Sometimes people gets confused and may convey the wrong message just by communicating through the internet. And if any instant help is needed that could be a struggle too.
