Among these functions of proof, this paper focuses on the discovery function that refers to invention of a new statement or conjecture by reflecting on or utilizing a constructed proof. Based on two cases in which eighth and ninth graders engaged in proofs and refutations, we demonstrate that facing a counterexample of a primitive statement can become a starting point of students’ activity for discovery, and that a proof of the primitive statement can function as a useful tool for inventing a new conjecture that holds for the counterexample. An implication for developing tasks by which students can experience this discovery function is mentioned.","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":"International Journal of Mathematical Education in Science and Technology. 45(7):1053-1067 (2014)","subitem_description_type":"Other"}]},"item_6_link_3":{"attribute_name":"信州大学研究者総覧へのリンク","attribute_value_mlt":[{"subitem_link_text":"Komatsu, Kotaro","subitem_link_url":"http://soar-rd.shinshu-u.ac.jp/profile/ja.jNACPhLh.html"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Taylor & Francis"}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1080/0020739X.2014.902135"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1080/0020739X.2014.902135","subitem_relation_type_select":"DOI"}}]},"item_6_rights_62":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"This is an Accepted Manuscript of an article published by Taylor & Francis in International Journal of Mathematical Education in Science and Technology, Published online: 03 Apr 2014, available online: http://www.tandfonline.com/ , https://doi.org/10.1080/0020739X.2014.902135 ."}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0020-739X","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00680498","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Komatsu,  Kotaro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tsujiyama,  Yosuke"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sakamaki,  Aruta"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-07"}],"displaytype":"detail","filename":"IJMEST_45_7_AM.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensefree":"This is an Accepted Manuscript of an article published by Taylor & Francis in International Journal of Mathematical Education in Science and Technology, Published online: 03 Apr 2014, available online: http://www.tandfonline.com/ , https://doi.org/10.1080/0020739X.2014.902135 .","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"IJMEST_45_7_AM.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/18632/files/IJMEST_45_7_AM.pdf"},"version_id":"916880e0-9bab-4242-8b0a-73c28062078b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"proof and proving","subitem_subject_scheme":"Other"},{"subitem_subject":"discovery function","subitem_subject_scheme":"Other"},{"subitem_subject":"refutation","subitem_subject_scheme":"Other"},{"subitem_subject":"counterexample","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Rethinking the discovery function of proof within the context of proofs and refutations","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Rethinking the discovery function of proof within the context of proofs and refutations","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["151"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-07"},"publish_date":"2017-02-07","publish_status":"0","recid":"18632","relation_version_is_last":true,"title":["Rethinking the discovery function of proof within the context of proofs and refutations"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:30:47.498474+00:00"}
