The present study purposed to examine the relation between Korean mothers’ conversational styles for inducing children’s personal narrative in their daily conversation with young children and the development of young children’s personal narrative and, ultimately, to provide basic materials for exploring mothers’ conversational styles helpful for the development of young children’s personal narrative. For this purpose, research questions were formulated as follows: 1. How is mothers’ conversational styles ? 1-1. What are the major factors of mothers’ conversational styles? 1-2. How different is mothers’ conversational styles according to the personal variables of young children (age, gender)? 2. How is the development of young children’s personal narrative? 3. How is the relation between mothers’ conversational styles and the development of young children’s personal narrative? The subjects of this study were 17 four‐year‐old children (9 boys and 9 girls) and 31 five‐year‐old children (15 boys and 16 girls), so a total of 48 young children at K Kindergarten in Wonju‐si, Gangwon‐do and their mothers, so a total of 48 pairs of mother‐child. In order to identify mothers’ conversational styles for inducing children’s personal narrative, we used the analysis tool used in the research of Resse and Fivush (1993). The tool for analyzing the development of children’s personal narrative was the standard for analyzing the development of children’s personal narrative suggested by Lee Yeong‐ja and Lee Ji‐hyeon (2005) based on the result of Peterson & McCabe and McCabe (1997). All the research process was recorded and transcribed. From transcribed data were obtained frequencies and percentages according to the research questions, and factor analysis was conducted to identify mothers’ conversational style. Difference in mothers’ conversational styles according to children’s personal variables was determined through t‐test, and the development of personal narrative was examined according to children’s gender and age. Lastly, we made trend analysis through one way ANOVA to determine the relation between mothers’ conversational style and the development of young children’s personal narrative. The results of this study are as follows: First, mothers’ conversational styles were found to be ‘elaborative style’ and ‘repetitive style’. The factors of the elaborative style were statement elaborations , question elaborations, evaluation and length, and the factors of the repetitive style were statement repetitions, question repetitions, fill-in-the-blank questions and statement, memory Prompt. As to difference in mothers’ conversational styles according to children’s personal variables, no difference was observed in mothers’ conversational styles according to children’s age and gender. Second, in the results of analyzing development of children’s personal narrative, no significant difference was observed in the development of children’s personal narrative according to gender and age. Third, according to the results of examining the relation between mothers’ conversational style and the development of young children’s personal narrative, the elaborative style showed statistical significance for the quadratic term of all its sub‐factors, namely, statement elaboration (F=5.79, p<.05), question elaboration (F=8.71, p<.05), evaluation (F=4.39, p<.05) and length (F=4.69, p<.05), but the repetitive style was found to be statistically insignificant. When the trends were examined, all the sub‐factors of mothers’ elaborative conversational style, namely, statement elaboration, question elaboration, evaluation and length increased while children’s daily narrative developed level 4 but the rate of their increase slowed down after level 4.
