Critical Thinking Richard 2010 states,
‘critical thinking is how to ask and answer questions in order to find out a solution.
’ In everyday life, the term ‘critical’ is often seen as negative or destructive. Being critical in academic life, however, does not mean
questioning things randomly. Instead, academic work aims to get as near as possible to the truth. Critical thinking in any subject or discipline is the way in
which this is done along with the more specialized applications of theory, the methods and techniques, which have been developed for the subject. Critical
thinking then, is the attempt to ask and answer questions systematically. This means asking the most useful questions in the most productive sequence in order
to yield a coherent and credible ‘story’. So thinking critically means asking and answering questions. Instead of
accepting ‘at face value’ what people read or hear, critical thinkers look for
evidence and for good reasons before believing something to be true. This is at the heart of what it means to be a scientist, researcher, scholar or professional in any
9 field. Whatever someone is studying, critical thinking is the key to learning and to
making progress. 1.6.4 SMPN 2 Yogyakarta
