This study aims to analyze the trends of research in ‘spoken grammar’ in Korean language education to identify the ways the research was studied in the past and is being studied in the present, and also propose a direction for future research. To do this, Chapter 1 overviews preceding studies in relevant fields and Chapter 2 describes the research subject and methodology. Dissertations dated until November 2019 and extracted from a search using keywords ‘spoken language’, ‘grammar’, ‘education’, and ‘Korean language’will be subject to the study. Spoken grammar is ‘a rule where a word is formed instantly according to the correct grammar, such that it can be seen as a language system combining the knowledge in grammatical rules and demonstration of practical skills’. Depending on how deep one looks into the spoken language, it can be comprised of ‘rules which appear during conversations’ to ‘rules in pronunciation which include colloquialities of all levels’. Chapter 3 materializes the relationship between the keywords by performing year-on-year analysis and topic analysis, as well as keyword-based network analysis. The year-on-year analysis demonstrates that studies in spoken grammar has increased since 2009, while the topic analysis extracts dissertations on conversational levels, requiring communication conditions, the most. The keyword analysis reveals that the words frequently emerge simultaneously and have high centrality around keywords such as use, communication, corpus, function, speaker, reality, conversation, story, and performance. Chapter 4 proposes a direction for subsequent studies and Chapter 5 summarizes the research. This study is highly significant as it comprehends the research done on spoken grammar objectively and in detail, and proposes a direction for subsequent studies.(Seoul National University)
