The purpose of this study is to explore the specificity of the College of Education's Writing course, and to propose a difference-making mechanism to find an educational approach. I looked at the peculiarities of the College of Education's Writing course in three respects. First, it is a singularity that occurs in writing learners. Unlike ordinary college writing learners, an education college writing learner is both a liberal and potential writing teacher. Second, it is a peculiarity that appears in the curriculum. The content, methods, and evaluation of the liberal arts and writing curriculum are directly and indirectly linked to the curriculum of the major courses. Third, it is a peculiarity that appears in the academic community. Family similarity is a peculiarity that occurs in the academic community of education colleges. In this study, I emphasized a tough approach to the differential generation mechanism. Finally, I analyzed the plans for Professor A's Writing course and proposed a direction for improvement.
