A session about Critical Thinking With Tim Moore

Today we (3Mont-ers) have an opportunity to meet Tim Moore, a representative of some Australian Universities. Tim Moore presented a topic about critical thinking from some different point of views. He interviewed some lecturer in Monash University from three different backgrounds. They gave a definition and comment about critical thinking from their perspective.
I try to understand the aim of critical thinking in each of background. I found the same purpose even it says in different ways. The main purpose of critical thinking is to understand whether something is a rubbish or values for us. Critical thinking is a way to identified something so we can say it needed or not.

There's no exact definition about critical thinking. A lecturer from Monash said "It's an interesting word, isn't it? it can be mean anything".

Again :

"The main purpose of critical thinking is to understand whether something is a rubbish or values for us"

Do a lot of reading!!!!
