The present study examined the methods of improving the oral production ability of Chinese learners of Japanese from the viewpoint of spacing effect. The spacing effect refers to the phenomenon that presentation material is better remembered when it is presented in a spaced condition than in a massed condition. Thirty-eight Chinese-speaking intermediate-level learners were divided into two groups, namely spaced and massed groups. Both groups were required to memorize conversational sentences of Japanese and were tested using free recall and oral production tests. The results showed that spaced condition led to better scores than massed condition in both tests. These results were interpreted from the viewpoint of elaboration. It is suggested that spaced presentation method should be adopted when memorizing Japanese conversational sentences, as it improves not only memorization but also oral production.
