番目とi+1番目の生育状態の関連性）と，不明確な0値との相関はほとんど認められなかった。よって，不明確な0値の発生には立木とは関わりのない要因が影響したと推測された。その要因としてグループ内の学生間のコミュニケーション不足が挙げられ，グループ分けの方法の改善や，0値のときの明確な表現についての指示が必要と考えられた。","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"環境科学年報
