본 연구에서는 중학교 수학의 이차함수 단원에 대하여 스마트 기기를 활용한 QR 코드 기반의 교수․학습 자료를 개발하고, 이를 W 중학교 3학년 학생 7명을 대상으로 한 5차시의 수업에 적용하여 수학적 태도의 향상 효과를 분석하였다. 그 결과 스마트 수업은 학생들의 수학적 태도에 긍정적인 효과가 있으며, 학생들은 스마트 수업이 재미있고, 즐거우며, 학습 이해가 잘된다고 하였다. 특히, 학습 부진 학생도 SNS를 통해 교사에게 직접 질문하여 궁금증을 해소할 수 있어 좋다고 하였다. 그러나 학습 분위기가 조금 산만하다는 부정적 측면도 있었다.
