運動会での異年齢保育の実践事例を通して，身体表現がそのねらいにどのような影響を与えるのかを検討した．

　結果として，異年齢のグループを『なかよしチーム』と名付け，そのチームで表現遊びに取り組んだことで，年少児と年長児の動きに，それぞれの持ち味が生かせ，互いの良さに気付き合うことができた．保育者が指導する際には，年齢による表現の違いを考慮し，言葉かけや導入方法などに配慮することが大切になる．異年齢では，年少児では難しいような表現も年長児と一緒だと表現することができた．また，年長児にとっては，年少児の無邪気な表現を見て，表現することの楽しさに気付くことができた．さらに，『なかよしチーム』だからこそ，一緒になってできた表現が多く見られた．運動会の作品つくりを通して，必要に応じた援助の仕方や，保育のねらいや内容を明確にする等の，事前事後の話し合いの大切さが確認された．

  Risk communication is generally conducted in order to promote good management for minimizing the negative effects of risks and resource expenditure. The means of reaching the intended audience is a problem for risk communicators. It is difficult for them to achieve good communication in conflict situations in which there is scientific uncertainty. Particular attention should be paid to environmental risks for children’s health, which is often the cause of disputes about solutions. In the present study, we focused on communicators’ anxiety and problems in the communication patterns related to risks, and organized a workshop that aimed to visualize anxiety, problems and their solutions. A total of 51 patterns (categorized into ten categories) were extracted for communication related to potential emerging risks. The extraction process in our workshop was also an effective opportunity for the participants to learn about risk communication. This approach will be repeated with different communities to achieve greater extraction and visualization of the risk communication pattern, and will improve techniques for achieving effective and substantial risk reduction.
