초록

본 연구는 인공지능 챗봇을 활용한 채팅 활동이 국내 대학생의 영어 문법 능력 향상에 미치는 영향을 조사한 것으로, 챗봇과의 채팅을 통해 실험 참가자의 영어 문법 능력이 실제로 상승하는지에 대한 여부를 알아보는 데 그 목적이 있다. 총 16주 동안 70명의 참가자가 챗봇 그룹과 인간 그룹으로 나뉘어 본 연구에 참여하였고, 참여인원은 각각 36명, 34명이었다. 챗봇 그룹은 수업시간에 배운 내용을 주제로 챗봇과의 채팅에 참여하였고, 인간 그룹은 같은 반 학생들끼리 짝지어 채팅을 진행하였다. 채팅 활동의 효과를 파악하기 위하여 본 연구 시작 전과 종료 후, 사전 사후 영어 문법 시험을 실시하였고, 그룹 간 비교를 위하여 독립표본 t검증을 실시하였다. 주요 결과 및 시사점은 다음과 같다. 사전 사후 평가 분석 결과, 두 그룹 모두에서 영어 문법 능력이 유의미하게 상승한 것으로 나타나 채팅 활동의 효과를 증명하였다. 문법 능력 상승에 대한 그룹 간 차이 역시 통계적으로 유의미한 것으로 밝혀져 국내 영어 교육에 있어서 챗봇의 긍정적인 역할을 확인하였다. 본 연구는 영어 문법 능력 향상을 위한 인공지능 챗봇 활용에 대한 시사점을 제시하는데 그 의의를 갖는다.

The purpose of this study is to explore the effects of the use of artificial intelligence chatbots on improving Korean college students' English grammar skills. 70 undergraduate students participated in the present study. They were taking a General English class offered by a university in Korea. There were two groups in this study. Participants in the chatbot group consisted of 36 students while those in the human group were 34. Over 16 weeks, the chatbot group engaged in ten chat sessions with a chatbot while the human group had a chat with a human chat partner. Both pre- and post-tests were performed to examine changes in the participants' grammar skills over time. To compare the improvement between the two groups, an independent t-test was then run. Main findings are as follows: First, participants in both groups significantly improved their English grammar skills, indicating the beneficial effects of engaging in chat. Also, there was a statistically significant difference in the improvement between the chatbot and human groups, indicating the superior effects of the chatbot use. This study confirmed the improved grammar skills by the participants in the chatbot group, comparison with those in the human group. Based on these findings, suggestions for the future chatbot study are discussed.
