The purpose of this research is to clarify the direction of the teaching improvement of the algebraic expression, based on the viewpoint that \"Mathematics is the science of patterns\". In order to achieve this purpose, I constituted the unit of the algebraic expression of the 2nd grade of a junior high school. Especially, in the activity where the students explain that “An odd number and an odd number makes an even number.”, I considered lesson deployment which focused on the mechanism of the odd number. After the analysis of the class, it was suggested that even if the teacher did not show the method represented by the algebraic expression or the method to explain it, the students could express the mechanism of the odd number by the algebraic expression, and could explain that “An odd number and an odd number makes an even number.” using the algebraic expression without help of the teacher. For the improvement of teaching the algebraic expression, it was suggested that it was an important viewpoint to focus on the mechanism of the algebraic expression and that of the odd number.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福井大学総合教職開発本部","subitem_publisher_language":"ja"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13427261","subitem_source_identifier_type":"ISSN"}]},"item_10002_text_25":{"attribute_name":"その他のID","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"TD10126747"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"草桶, 勇人","creatorNameLang":"ja"},{"creatorName":"クサオケ, ハヤト","creatorNameLang":"ja-Kana"}]},{"creatorNames":[{"creatorName":"Kusaoke, Hayato","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-05-08"}],"filename":"BD10126747.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","url":{"url":"https://u-fukui.repo.nii.ac.jp/record/2000224/files/BD10126747.pdf"},"version_id":"d5ceba7d-fb3f-411a-bcb1-d3d63b0ca767"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"文字式","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"パターンの科学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"しくみ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"奇数","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"algebraic expression","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"the science of patterns","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mechanism","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"odd number","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"「数学はパターンの科学である」の考えを視点とした文字式の単元構成 : ―「パターンの探究」としての文字式や整数の「しくみ」を考察することに焦点を当てて―","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"「数学はパターンの科学である」の考えを視点とした文字式の単元構成 : ―「パターンの探究」としての文字式や整数の「しくみ」を考察することに焦点を当てて―","subitem_title_language":"ja"},{"subitem_title":"The Constitution of the Units of the Algebraic Expression, based on the viewpoint that \"Mathematics is the science of patterns\" : Focus on examining \"the mechanism\" of the algebraic expression and the integers as \"the research of patterns\"","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"18","path":["1715132995096"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-05-08"},"publish_date":"2024-05-08","publish_status":"0","recid":"2000224","relation_version_is_last":true,"title":["「数学はパターンの科学である」の考えを視点とした文字式の単元構成 : ―「パターンの探究」としての文字式や整数の「しくみ」を考察することに焦点を当てて―"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-05-08T07:43:28.241278+00:00"}
