수학 과제의 역할은? | 수학 과제(Mathematical Task)는 학생들이 수학을 이해하고, 수학적으로 사고하기 위한 교실 활동의 중요한 요소이다. 특히 교과서에 제시된 과제의 한계를 극복하기 위해, 최근 내용 규준에 맞도록 교과서 과제를 변형하기 위한 시도가 이루어지고 있다(김하림,2017; 이근범, 2017; 박진형, 2018). | |
전통적인 탱그램이란? | 탱그램(Tangram)은 분할 방법에 따라 여러 가지 형태가 있을 수 있다. 전통적인 탱그램은 정사각형 모양을 7개의 조각으로 나눈 것이며, 중국에서 만들어진 것으로 알려져 있으나 그 기원은 불분명하다. | |
교사가 교과서 과제를 바탕으로 각 학급의 특성을 반영한 과제 변형을 시도할 수 있어야 하는 이유는? | 요약하면, 탱그램 활동은 학생 중심 활동이 되어야 하며, 이를 통해 직관적으로 도형의 특성을 파악할 수 있어야 한다. 교과서 과제는 전형적인 형태로 제시되어 있으며, 지역적 특성이나 모든 학급의 특성을 반영하기 어렵다. 따라서 교사는 교과서 과제를 바탕으로 각 학급의 특성을 반영한 과제 변형을 시도할 수 있어야 한다. |
