This Special Issue showcases a collection of articles that illustrate ways of teaching conversational skills in the KFL/KSL classroom setting based on insights from conversation analysis (CA). Conversations are the foundation of language use, as well as the medium and goal for much of language learning (Wong & Waring, 2010). In order to competently engage in conversation, speakers need the ability to jointly communicate, co-construct talk, maintain shared understanding and participation, and accomplish actions with other co-participants (He & Young, 1998). CA provides empirical descriptions of how social interaction works and how speakers competently engage in socially organized interaction by describing their turn designs, actions, activities, and overall structure of interaction. Recent studies in the field have applied burgeoning CA findings to the practice of teaching second/foreign language. These studies have successfully shown how CA can be used in the classroom to help enhance the learners' conversational skills in concrete ways (Barraja-Rohan, 1997, 2011; Packett, 2005; Yoon, 2007).The Special Issue consists of five articles that present key routinized interactional practices that learners need to acquire to interact competently in Korean: alignment, assessment, news enquiries, question and response design, and reported talk. Stance alignment—The use of the interrogative suffixes -nya and -ni as stance alignment markers (by Seunggon Jeong, Eun Young Bae, Jaerin Ahn)Assessment—The use of the sentence-ending suffixes -ney and -ci in assessment sequences indexing epistemic positions and affiliation (by Kyoungmi Ha)News enquiry and assessment—The use of topic particle nun in itemized news enquiries and assessment contexts (by Kyu-hyun Kim)Question and response—Teaching discourse markers that mark trouble with questions (by Stephanie Hyeri Kim)Reported talk—Diverse designs, functions, and positions of reported talk in interaction (by Mary Shin Kim) All articles identify and address the gap between the way these practices and relevant linguistic forms are typically taught in Korean language classrooms and how they are actually designed and utilized by participants in social interaction. Awareness of such discrepancies provides a crucial perspective for teaching and learning conversational skills. Furthermore, the articles provide step-by-step tasks and hands-on activities directly applicable in classrooms. All activities are designed according to specific levels of proficiency and the respective needs of students.I am deeply grateful to Dr. Hae-Young Kim who saw the need for publishing studies on interaction-based pedagogy from a CA perspective and provided this opportunity to compile these works as a Special Issue. I also express my deep gratitude to the authors who endeavored to bridge CA findings from empirical research and Korean language pedagogy. I hope the Special Issue will interest teachers and learners, as it aims to enhance understanding of the link between interaction and language, inspire more competency-based and interaction- oriented pedagogies for KFL/KSL classrooms, and broaden the goals of language learning so that learners can become more competent in social interaction.
