디지털교과서 활용 효과에 관한 영향 - 6학년 수학 쌓긴나무 단원을 중심으로 -

A Study on the Effects of Using Digital Textbook - Focused on Stacking Cubes Activities in 6th Grade -

본 연구는 초등학교 6학년 수학 쌓기나무 단원의 디지털교과서 활용 수업이 공간능력, 수학학업성취도, 수학 교과에 대한 흥미도 등에 미치는 영향을 분석함으로써 수학 수업에 있어서 학습효과를 향상시킬 수 있는 방안을 모색하고자 하는데 그 목적이 있다. 위의 연구를 위하여 실험반은 디지털교과서, 비교반은 서책교과서로 수업을 진행하였다. 그 결과 실험처치 후 실험반과 비교반의 공간 감각 능력 및 수학 교과에 대한 흥미도에 있어서 통계적으로 유의미한 차이는 발견할 수 없었다. 그러나 공간능력 성적의 중위 그룹에서 실험반이 통계적으로 유의미하게 높게 나타났는데, 이는 디지털교과서가 다수의 중위권 학생들에게 학습에 대한 관심을 유도하고 흥미를 유지시키는 역할을 할 수 있다는 점을 시사한다. 또한 공간 능력 검사지의 대부분의 문항에서 실험반이 더 높은 정답률을 보인 점은 구체물과 멀티미디어를 병행 활용한 학습 형태가 공간 능력에 긍정적인 영향을 주었을 가능성이 있음을 보여준다.

The purpose of this study was to investigate the effects of digital mathematics textbook on spatial abilities, interest and achievement of 6th graders. For this, research questions were set as follow: A. Is there any difference in cognitive ability in the space perception test between the experimental group and the control group. B. What distinctive attributes exist between the experimental group and the control group in the Spatial abilities? C. Is there any difference in learners' interest and achievement between the experiment group and the control group. To investigate the research questions, two classes of 6th grade children were selected from an elementary school in Daejeon and assigned one as experimental group and the other as control group. The experimental group studied mathematics using Digital Textbooks under an individual PC environment while the control group studied using the existing book-type textbooks. The following results and conclusions were obtained from the research. First, the effect of the Digital Textbooks on children's mathematics achievement was not statistically meaningful even though there was some progress in children's achievement. Furthermore, it was not found that the usage of a Digital Textbooks consistently influenced improvement in the students' interest in mathematics. Second, there were some positive changes in the achievement of Spatial ability of the middle subgroup of pretest score in the experiment group. It can have some educational implication that the Digital Textbooks can affect positively to the middle group in mathematics achievement who dominated more than 50% of the class. Third, the number of correct answers was found to be somewhat higher than that of the control group in spatial reasoning items. This means that the learning environment with Digital Textbooks allow more opportunities for manipulating geometric objects physically and mentally. Therefore, It seems necessary to offer various resources such as digital contents for students' geometric learning. For future research, It is strongly recommended to fix the bugs of the digital textbook programs and to upgrade the operating system of the computer.
