본 연구의 목적은 2세 표준보육과정, 3∼5세 누리과정과 초등학교 1학년 교육과정 간의 수학교육 내용의 연계성을 살펴보는 것이다. 분석대상은 2세 표준보육과정 세부내용 9개, 3∼5세 누리과정 세부내용 34개(3세 8개, 4세 11개, 5세 15개), 초등학교 1학년 수학과 성취기준 15개였다. 분석결과 첫째, 수와 연산에서는 2세 표준보육과정과 3세 누리과정 간에 확대, 심화, 확대․심화로 연계되었고, 5세 누리과정과 초등학교 1학년 교육과정 간에는 대부분 확대․심화로 연계되거나 소멸, 생성의 형태로 비연계되는 것으로 나타났다. 둘째, 공간과 도형에서는 2세와 3세 간에 반복, 심화의 형태로 연계되었고, 5세와 1학년 간에는 반복의 형태로 연계되거나 소멸의 형태로 비연계되었다. 셋째, 측정에서는 2세와 3세 간에 확대․심화로 연계되었고, 5세와 1학년 간에는 반복으로 연계되거나 소멸, 생성의 형태로 비연계되었다. 넷째, 규칙성에서는 2세와 3세 간에 반복의 형태로 연계되었으며, 5세와 1학년 간에는 확대․심화로 연계되거나 생성의 형태로 비연계되기도 하였다. 다섯째, 자료 분석과 결과 나타내기에서는 2세와 3세 간에 심화의 형태로 연계되었으며, 5세와 1학년 간에는 모든 내용에서 소멸되어 비연계되는 것으로 나타났다. 마지막으로 연계율을 분석한 결과, 2세와 3세 간 연계율 및 3세와 4세 간 연계율은 100%로 각각 8개, 11개의 내용이 모두 연계되었고, 4세와 5세 간 연계율은 80.0%로 15개 중 12개의 내용이 연계되었다. 5세와 1학년 간 연계율은 47.4%로 19개 중 9개의 내용이 연계된 것으로 나타나 상대적으로 연계율이 가장 낮은 것으로 분석되었다.
The purpose of this study was to investigate connectivity in mathematics education among the standard child care curriculum for 2-year-old children, the nuri curriculum for 3 to 5-year-old children and the curriculum for the first graders in elementary school. The subjects were 9 details of the standard child care curriculum, 34 details of the nuri curriculum and 15 details of the elementary school curriculum. The results of the study were as follows. First, in number and operations, between 2- and 3-year-old, the curricula were connected with ‘extension’, ‘reinforcement’ or ‘extension and reinforcement’ and between 5- and first graders, the curricula were connected with ‘extension and reinforcement’ and were disconnected with ‘extinction’ or ‘creation’. Second, in space and figure, between 2- and 3-year-old, the curricula were connected with ‘repetition’ or ‘reinforcement’ and between 5- and first graders, the curricula were connected with ‘repetition’ and were disconnected with ‘extinction’. Third, in measurement, between 2- and 3-year-old, the curricula were connected with ‘extension and reinforcement’ and between 5- and first graders, the curricula were connected with ‘repetition’ and were disconnected with ‘extinction’ or ‘creation’. Fourth, in patterns, between 2- and 3-year-old, the curricula were connected with ‘repetition’ and between 5- and first graders, the curricula were connected with ‘extension and reinforcement’ and were disconnected with ‘creation’. Fifth, in the data analysis and the result presentation, between 2- and 3-year-old, the curricula were connected with ‘reinforcement’ and between 5- and first graders, the curricula were disconnected with ‘extinction’. The connection rate between the ages of 2 and 3 was 100%, all of 8 items were linked, and the connection rate between the ages of 3 and 4 was 100%, all of 11 items were linked. In addition, the connection rate between the ages of 4 and 5 was 80.0%, 12 out of 15 items were linked. The connection rate between the ages of 5 and first graders was 47.4%, 9 out of 19 items were linked, which is analyzed to have a high ratio of non-linked
