"클라이 BT(Be a Teacher) 앱은 학생이 선생님처럼 자신이 배운 내용을 정확히 이해하고 말로 설명할 수 있도록 돕는 영어 학습 보조 프로그램입니다. 아인슈타인 曰 “설명하지 못하면 충분히 이해하지 못한 것이다.” 아날로그에서 디지털로 변화하듯 우리 교육도 이제 암기식의 일방적 주입식 교육을 벗어나 토론 수업, 구술/논술 평가 형태로 변화하고 있습니다. 이 변화의 핵심을 관통하는 토론 방식의 유대인 교육법 ‘하브루타’. 그 시작은 학생 스스로 이해한 것을 직접 말로 설명하는 것입니다. 클라이 BT 앱은 문법, 말하기, 단어, 독해, 작문 등 영어의 모든 영역에서 그 설명하기가 가능하도록 치밀하게 설계된 학습 프로그램입니다. 이제 클라이 BT앱을 통해 선생님처럼 이해한 내용을 완벽히 설명하는 학생의 모습을 만나 보실 수 있습니다."
