This study presents how college freshmen students reflect on their writing skills using a triangular writing process. A triangular writing process consists of Clog as a freewriting format, personal journal log as an informal writing format, and writing assignments as a formal writing format. Participants were 47 undergraduate students who took "College Writing" course, a course required in liberal arts upon entering college. Followed by a nature of qualitative study, the study data was collected through open-ended questionnaire and narratives. Through thematic analysis, the study results revealed the three main themes emerged from a reflection of a triangular writing process: 1. expressing thoughts and ideas; 2. applying writing style, 3. enjoying self-directed writing. The study results suggested that student writers need to make a connection between informal and formal writing formats in order to exercise writing which can be continually circulated throughout the semester and help students to become fluent in writing as well as gaining competency. A suggestion for further research on an L2 writing class is presented as well as study limitations.
