Among the four language skills, writing is considered as the most challenging and difficult skill for most of the foreign language learners (Reid, 2002). Moreover, the development of students' L2 writing can be influenced by multiple factors such as L1 writing ability, L2 proficiency, and writing experiences in both languages (Kobayashi & Rinnert, 2008; Kubota, 1998). The starting point of this study was the difficulties students face in their writing process observed during the in-class writing tasks (Kobayashi & Rinnert, 2008; Kubota, 1998). This study aims to find out students' perceptions of difficulties they come across during their writing process in Writing Skills I-II courses in which they are supposed to write academic paragraphs and essays.
