Abstract

In an effort to investigate the effects of chatbots on English listening and reading skills, 46 college students participated in the current study. Participants consisted of first-year students who enrolled in an English class at a university in South Korea. They were randomly divided into two groups: one experimental group (n=24) and one control group (n=22). During 16 weeks, the experimental group engaged in chats with a chatbot, named Elbot, while the control group did not. There were pre- and post-tests to confirm the effects of the chatbot usage. Major findings are as follows: First, participants in both groups significantly improved listening and reading skills. On the post-listening test, however, the experimental group showed more improvements. Their listening proficiency level improved from intermediate to advanced level after engaging in chat with the chatbot. Limitations and implications for theory and practice are discussed at the end.

본 연구는 챗봇의 활용이 국내 대학생의 영어 듣기 및 읽기 학습에 미치는 영향을 조사한 것으로, 실험 참가자의 영어 듣기 및 읽기 능력이 챗봇과의 채팅을 통해 실제로 상승하는지에 대한 여부를 알아보는 데 그 목적이 있다. 본 연구를 위해 총 46명의 참가자를 실험그룹과 통제그룹으로 나누어 16주 동안 실험을 진행하였으며, 실험 시작 전과 실험 종료 후 사전 사후 평가를 실시하여 챗봇 활용의 효과를 파악하였다. 본 연구의 주요 결과 및 시사점은 다음과 같다. 사전 사후 평가 결과 실험그룹과 통제그룹 모두에서 영어 듣기 및 읽기 능력이 유의미하게 상승한 것으로 나타났다. 특히 영어 듣기능력과 관련하여 실험그룹이 통제그룹보다 사후 평가에서 더 많은 상승폭을 보임으로써 듣기 능력 향상에 대한 챗봇 활용의 효과를 증명하였다. 본 연구는 4차 산업혁명 시대에 따라 영어 학습을 위한 챗봇 활용에 대한 시사점을 제시하는데 그 의의를 갖는다고 볼 수 있다.
