The term \"ratio\" first appears in the fourth-grade textbook \"The Double View,\" but because it is not particularly emphasized, it does not remain in the consciousness of children. In the  fifth grade, \"size per unit amount\" and then \"ratio\" followed. Since the relationship between each subject is not fully understood, each subject becomes independent, and what has already been learned is not utilized. This makes it more difficult to understand. By examining several issues related to \"ratio,\" we will clarify the relationship between the subjects related to \"proportion\" and consider what \"ratio\" is in the mathematics department.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_full_name_3":{"attribute_name":"著者（英）","attribute_value_mlt":[{"familyNames":[{"familyName":"Ishihara","familyNameLang":"en"},{"familyName":"石原","familyNameLang":"ja"},{"familyName":"イシハラ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Sunao","givenNameLang":"en"},{"givenName":"直","givenNameLang":"ja"},{"givenName":"スナオ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"794","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000388550073","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000388550073"}],"names":[{"name":"Ishihara, Sunao","nameLang":"en"},{"name":"石原, 直","nameLang":"ja"},{"name":"イシハラ, スナオ","nameLang":"ja-Kana"}]}]},"item_10001_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57314/0002000127","subitem_identifier_reg_type":"JaLC"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東北福祉大学教職課程支援室","subitem_publisher_language":"ja"}]},"item_10001_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ishihara, Sunao","creatorNameLang":"en"},{"creatorName":"石原, 直","creatorNameLang":"ja"},{"creatorName":"イシハラ, スナオ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Ishihara","familyNameLang":"en"},{"familyName":"石原","familyNameLang":"ja"},{"familyName":"イシハラ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Sunao","givenNameLang":"en"},{"givenName":"直","givenNameLang":"ja"},{"givenName":"スナオ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"794","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000388550073","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000388550073"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2024-04-30"}],"filename":"pp.1-11 石原直.pdf","filesize":[{"value":"901 KB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"url":"https://tfulib.repo.nii.ac.jp/record/2000127/files/pp.1-11 石原直.pdf"},"version_id":"f889230a-e8e2-4184-97f9-0847b2b5c667"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"算数科","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"割合","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"倍","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"比","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"比例","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"単位量あたりの大きさ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"学習指導","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"mathematics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ratio","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fold","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"proportion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"size of the per unit amount","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"educational guidance","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"算数科における『割合』とは何か －なぜ「割合」が難しいと言われるのか－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"算数科における『割合』とは何か －なぜ「割合」が難しいと言われるのか－","subitem_title_language":"ja"},{"subitem_title":"What is \"ratio\" in mathematics? －Why is \"ratio\" said to be difficult?－","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"15","path":["1712561147130"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-30"},"publish_date":"2024-04-30","publish_status":"0","recid":"2000127","relation_version_is_last":true,"title":["算数科における『割合』とは何か －なぜ「割合」が難しいと言われるのか－"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-08-06T02:10:23.983284+00:00"}
