This paper focuses on an analysis of students' representations of fractions as they work on the fraction comparison tasks and justify their solutions in a collective classroom activity. The importance of setting a problematic situation and encouraging students to make various representations for their meaningful learning mathematics is exemplified. Some implications for teacher's activity and school mathematics curriculum are also suggested.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Department of Mathematics Education, Faculty of Education, Hiroshima University"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0919-1720","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN10444573","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"1"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1998-03","bibliographicIssueDateType":"Issued"},"bibliographicPageEnd":"11","bibliographicPageStart":"1","bibliographicVolumeNumber":"6","bibliographic_titles":[{"bibliographic_title":"Hiroshima journal of mathematics education"},{"bibliographic_title":"Hiroshima journal of mathematics education"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"HiroshimaJMathEduc_6_1.pdf","filesize":[{"value":"746.5 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2006975/files/HiroshimaJMathEduc_6_1.pdf"},"version_id":"3bd831ca-3894-4f9c-814d-cd2e5eeff023"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"29288"},"item_title":"Students' Representations of Fractions in a Regular Elementary School Mathematics Classroom","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2006975","relation_version_is_last":true,"title":["Students' Representations of Fractions in a Regular Elementary School Mathematics Classroom"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-21T08:52:51.387787+00:00"}
