深まりのある意見交換は接触場面において どのように達成されるか － 対話／共話との関連から －

The purpose of this study was to obtain suggestions for teaching in a classroom in order to achieve a sufficient conversation by discussion and we explored what kind of characteristics we could observe in conversation that we could observe a deep discussion in terms of contents. For the analysis, we focused on the differences in speaking through dialogue and co-operative conversation. As a result, we could observe a common point that pairs with a deep discussion have a higher frequency of co-operative conversation and based on the conversation example, we could observe a scene in which they enhanced recognition that they had same opinions each other by speaking through co-operative conversation while discussion. Furthermore, for a pair who had a different opinion at the beginning of discussion, it was shown that they acknowledged ideas from the partner by speaking through co-operative conversation, clarified their ideas by speaking through dialogue, and compromised with the conversation partner. As a result of this study, we can assume that participants in conversation can have a sense of security against the other speaker and speak with open mind by enhancing consensus or accepting different opinions from the partner by speaking through co-operative conversation as well as clarifying mutual opinions by speaking through dialogue, which contributes to a deep discussion in terms of contents.
