determined that having critical thinking skill has necessity in this modern world because that kind of thinking are needed in facing problems in real life.
Therefore, the importance of critical thinking cannot be ignored, particularly in education. To answer the research questions, Pearson Product Moment correlation
coefficient was applied in this study.
Based on the findings described in the previous chapter, this study comes to the conclusion that there is significant relationship between critical thinking
skill and argumentative writing skill of the twelfth grade students of SMA Kharisma Bangsa, academic year 20152016. It reveals that the student who has
good critical thinking skill, has good argumentative writing skill: whereas, the student who has poor critical thinking skill tends to have poor argumentative
writing skill as well. It is proven by the Pearson Product Moment correlation coefficient result which the value is 0.573 which is higher than r table value
=0.573 = 0.304 and
=0.573 = 0.393. Furthermore,
critical thinking skill has 32.8 contribution in the students’ argumentative writing skill. Therefore, it can be concluded that the more critical the students
think, the more creative and critical they are in developing the ideas in writing.

argumentative writing skill of the twelfth grade of SMA Kharisma Bangsa academic year 20152016. The percentege of CT skill contribution twowards
argumentative writing skill is 32.8. Consequently, it is highly recommended to the English teachers of SMA Kharisma Bangsa to design the writing courses that
not only facilitate students to develop their writing skill but also to develop students’ critical thinking skill. Therefore, the students can explore and develop
their critical thinking skill as well as their argumentative writing skill.
C. Suggestions
Based on the conclusion and the implication, it can be reached some suggestions for the students, teachers and everyone involved in the teaching and
learning process of writing skills. 1.
For the English teachers of SMA Kharisma Bangsa, they are expected to design the writing course where they can teach both critical thinking skills
and writing skill, argumentative writing in particular. It is because there is significant relationship between critical thinking skill and argumentative
writing skill. Furthermore, Time for teaching critical thinking techniques in argumentative writing is recommended to increase.
2. For the teachers, they should teach critical thinking ability to the students
because it has many impacts in students’ real life. It is not only important for the students’ academic performance such as writing skill but also can help
students to face the problems in their real life. Because critical thinking is a skill: therefore, it is highly importance for students to be taught in lower
grades so that they will be critical thinkers since their early grade. 3.
For students, especially students of SMA Kharisma Bangsa, they should be aware with the issue and problem happened around them. They have to
