Critical thinking is one of the new models in education system. This model pays
special attention to the development of individual and social features of people
so that mental power and social responsibilities will be fostered among the
learners. Dewey believes that schools should be based on people cooperation
and its result should be training citizens (A. Haynes, 2002). In critical thinking
strategy, the creation of thoughts, their expression and putting them to practice
are emphasized as a fundamental characteristic of judgment. Critical thinking is
important in both individual and social aspects. Since in critical thinking the
human being is considered free, he is helped to decide about his way of life. In
daily life, we need to have a high power of selectivity to face different
situations in life. The success will be achieved only when people are able to
make right selections in these situations.
