Do you know about critical literacy? and how about reasoning skills.Do you know the purpose of critical thinking ?since i need to complete my chapter on this two thing i would like to share with you about my understanding regarding this subjects. 
According to www.wikipedia.org.com,critical thinking actually about  the process of thinking that questions any assumptions. It is a way of deciding whether a claim is true, false, sometimes true, or partly true. Another definitions about critical thinking is a synergistic thought process that provides justification when reassessing one's reality by weighing and considering personal observation against contradicting opinion.  It is also about a thought process that considers both sides of equation before concluding something to be true. Actually there are many definitions that can be classified to critical thinking, but for me critical thinking is an active process which is people need to think about anything in serious and  deeply with full of consideration. Actually without we realizes, we are actually usually use critical thinking in our daily life. For example, the students always to thinking about the fashion that they must to wear for the next day with consider the schedule and the activities that planned for that day. According to cf. Norris and Ennis, 1989 " critical thinking is reasonable and reflective thinking that is focused on deciding what to believe or do. 


The purpose of critical thinking is people to achieve understanding, evaluate view points, and solve problems in daily life. Since all three areas involve the asking of questions, we can say that critical thinking is the questioning or inquiry we engage in when we seek to understand, evaluate, or resolve." 
Maiorana, Victor P. Critical Thinking Across the Curriculum: Building the Analytical Classroom. 1992. So, in order to make any decisions or especially very important decision, people need to use their critical thinking skills wisely. ok,how about your opinion about critical thinking?what is the ever most critical times that you ever had in your life?let share something with me=) we will talk about reasoning skills in my future post..

                        Critical Thinking is “the art of thinking about your thinking while you are thinking in order to make your thinking better: more clear, more accurate, and more defensible.”
