This paper aims at suggesting a method to teach Korean historical linguistics for pre-service teachers in college. This tries to overcome the problems that current historical linguistics has too much content as well as is not fundamentally helpful for current language usage by focusing on the knowledge production of historical linguistics. It is the very beginning stage of the knowledge production of historical linguistics to analyze historical records in sequence, which needs to be associated with the subsequent, integrative thinking process later on. Learners can be aware of how to discover linguistic order only through the way to approach toward historical linguistics in respect of Korean language education. For this, the lecturers responsible for historical linguistics in college need to encourage their students, Korean pre-service teachers, to contact the historical records with the language involved in discovery process. In addition, they should provide pre-service teachers with the appropriate feedback. Through this process, pre-service teachers, who need to design their lessons by themselves, can enhance their insight on Korean historical linguistics. This activity includes the process of understanding, analyzing and discussing related issues with the lecturers. To make successful result, the lecturers should be equipped with the insight to understand the variables in classroom and need to reflect them in their curriculum.
