본 연구는 초등학교 1학년 학생을 대상으로 등호의 관계적 이해를 강조한 수업에서 나타나는 학생의 노티싱을 초점의 중심, 집중하는 상호작용, 수학 과제, 수학 활동의 본질의 네 가지 측면에서 분석하였다. 구체적으로 선행연구에서 도출한 지도방안을 등호를 처음 도입하는 1학년 덧셈과 뺄셈 단원에 적용하여 등호의 관계적 이해를 강조한 수업을 실행하고, 이 과정에서 나타난 학생의 노티싱을 종합적으로 분석하였다. 그 결과 실제 수업 맥락에서 초점의 중심은 등식의 구조와 과제 형태, 교사와 학생의 상호작용, 교실 관행 등에 영향을 받았으며, 특히 학생이 등호를 관계적으로 인식할 수 있도록 돕는 특정한 교사와 학생의 상호작용을 발견할 수 있었다. 또한 크기가 같은 두 양에 주목하는 경우와 양변의 관계에 주목하는 경우 등식을 관계적으로 추론할 수 있었던 것과 같이 등식에 대한 학생의 노티싱은 등식을 추론하는 방식에 영향을 미친다는 것을 알 수 있었다. 이러한 연구결과를 통해 등호의 지도 방안에 대한 시사점을 제시하였다.
This study analyzed student noticing in a lesson that emphasized relational understanding of equal signs for first graders from four aspects: centers of focus, focusing interactions, mathematical tasks, and nature of the mathematical activity. Specifically, the instructional factors that emphasize t...
