Abstract

The purpose of this study is to find out whether there is a difference in achievement between blocked practice and interleaved practice according to the difference in domain and type of learning content in mathematics subject, and through this result, it is to confirm whether the effect of interleaved practice in mathematics learning is due to the 'Discriminative-contrast Hypothesis' or the 'Distributed-practice Hypothesis'. Although interleaved practice is more effective than blocked practice, previous studies have not shown consistent results regarding the cause. Therefore, in this study, 103 first-year middle school students were randomly assigned to blocked practice, interleaved practice, remote blocked practice, and remote interleaved practice groups had learning activities over 4 times. The results reveals that the effect of interleaved practice appeared in similar types in the same domain, but the effect of interleaved practice did not appear in different types in different domain. In addition, through this result, it was confirmed that the effect of interleaved practice was due to the 'Discriminative-contrast hypothesis' rather than the 'Distributed-practice hypothesis'. Further research topics were suggested after the issues on the research method and the findings were discussed.

본 연구의 목적은 수학교과에서 학습하는 내용이 영역과 유형의 차이에 따라 구획연습과 교차연습의 성취도 차이가 나는지 알아보고 이 결과를 통해 수학학습에서의 교차연습의 효과가 '분산-연습 가설'에 의한 것인지 혹은 '구분-대조 가설'에 의한 것인지를 확인하는 것이다. 교차연습이 구획연습보다 효과적이라는 연구가 대부분이지만 그 원인에 대해서 선행 연구들은 일관된 결과를 보이고 있지 않다. 이에 본 연구에서는 D광역시 중학교 1학년 103명을 구획연습, 교차연습, 먼-구획연습, 먼-교차연습 집단으로 무작위 배치하여 4회에 걸쳐 학습활동을 하였고 일주일의 파지간격을 둔 후 최종검사를 실시하였다. 그 결과, 동일한 영역에서의 유사한 유형에서는 교차연습의 효과가 나타났고, 서로 다른 영역의 다른 유형에서는 교차연습의 효과가 나타나지 않았다. 또한, 이 결과를 통해 교차연습의 효과는 '분산-연습 가설'보다는 '구분-대조 가설'에 의한 것임을 확인할 수 있었다. 연구결과와 연구방법에 대한 논의를 통해 후속 연구가 필요한 연구문제를 제안하였다.
