One of the four basic language skills of children, writing, is central to expressing themselves and to developing high level thinking capabilities. Competence in writing is a rather complex learning structure in which cognitive and, especially, psycho-motor learning processes are intensively employed and it further needs to be fed by perceptive processes. In these processes, on the one hand, students cognitively exhibit learning products oriented to creative high level thinking. On the other hand, they have to behave according to mind-muscle coordination. The aim of this research is to figure out the cognitive processes regarding how the students show an approach to writing competence in English, making use of the affirmations of the students. This study has focused on 90 10th grade students and the research has been qualitatively designed. The study has employed an open-end interview form in order to determine the cognitive processes used by the students and what they think while writing. Utilizing the data from these interview forms, the study has attempted to describe students' opinions regarding writing in English with concept map methodology, and to constitute English writing competence thinking profiles of the students. When results of the research are examined, it is observed that the students have mentioned what writing in English means to them; the factors that affect their writing process; the success-determining factors for writing in English; which topics they prefer to write about; their attitude towards writing; their expectations from teachers who instruct them to write in English; which learning methods they prefer; how their writings should be evaluated and so forth.
