Abstract

Coinciding with the advent of COVID-19, online education is on the rise both domestically and globally, and has become an absolutely necessary and irreplaceable form of education. It is a very curious question what the perception of people about the suddenly growing form of education is, and how it has changed. This study investigated changes in consumers' perception of online education using big data. To this end, we divided the time into four stages: before COVID-19 (November to December 2019), after the triggering of COVID-19 (January to February 2020), right after the online classes started (March to April 2020), after experiencing some online education (May to June 2020). Then we conducted text mining, namely, keyword frequency analysis, network analysis, word cloud analysis, and sentiment analysis were performed. The implications derived as a result of the analysis can help education policy makers and educators working in the field to improve online education quality and establish its future directions.

COVID-19 이후 국내는 물론, 전 세계적으로 온라인 교육은 절대적으로 필요하며 대체 불가한 교육 형태가 되었다. 온라인 교육이 급부상 하면서 교육 형태에 대해 사람들이 가지는 인식은 어떠한지, 만약 변화가 있다면 어떻게 변화했는지는 매우 궁금증을 자아내는 질문이다. 본 연구는 온라인 교육에 대한 소비자 인식의 변화 추이를 빅데이터를 활용하여 조사하였다. 이를 위해 코로나 이전(2019년 11월-12월), 코로나 촉발 이후(2020년 1월-2월), 온라인 개강직후(2020년 3월-4월), 온라인 교육을 일정 정도 경험한 이후(2020년 5월-6월)의 4개의 구간으로 구분하고, 텍스트 마이닝 즉, 키워드 빈도분석, 워드클라우드 분석, 네트워크 분석, 감성 분석을 수행하였다. 시기별로 온라인 교육 관련 키워드의 출현빈도는 코로나 이전에는 학점은행제, 평생교육, 블로그 등에서 코로나 이후 학교 개강이 시작되면서 온라인 개학, 비대면 교육, 실시간, 콘텐츠 제작, 유튜브 등으로 변화하였다. 감성분석 결과, 코로나 사태 이전에는 공지안내, 정보교류 등의 중립글이 대부분이었으나, 코로나 발생을 계기로 온라인 교육에 대한 사람들의 인식과 평가에 대한 긍정 및 부정의 의견이 논의되기 시작하였다. 또한 미래 온라인 교육시장의 확산과 전망 등 방향성에 대해서도 관심이 증대되었다. 온라인 교육은 발전가능성이 높은 만큼 앞으로 개선해야 할 부분들이 많겠으나, 교육 정책입안자, 현장에서 일하는 교육자들에게 온라인 교육 품질 개선 및 향후 나아갈 방향 수립에 도움을 줄 수 있을 것이다.
