For this purpose, this paper organizes and examines relevant literature and previous studies, and conceives a lesson that encourages students to relate the four-square area diagram to equations, numbers, and words. The performance of the children before and after the class was evaluated using a rubric. A significant difference was found in the test of the difference in the percentage of children who achieved the pre- and post-assessment criteria, indicating that the conceived lesson was effective in preparing students for the multiplication of linear expressions.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"広島大学大学院人間社会科学研究科教職開発専攻"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186819068":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15027/52084","subitem_identifier_reg_type":"JaLC"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"2433-8664","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AA12860624","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"開始ページ","attribute_value_mlt":[{"subitem_start_page":"11"}]},"item_1617187056579":{"attribute_name":"bibliographic_information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2022-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicPageEnd":"21","bibliographicPageStart":"11","bibliographic_titles":[{"bibliographic_title":"教職開発研究"},{"bibliographic_title":"Journal of Professional Development for Teachers and School Leaders"}]}]},"item_1617258105262":{"attribute_name":"item_1617258105262","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"出版タイプ","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":"JPDTSL_5_11.pdf","filesize":[{"value":"1.0 MB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2018478/files/JPDTSL_5_11.pdf"},"version_id":"666decfe-d72f-437b-80d0-f548db0243be"}]},"item_1617620223087":{"attribute_name":"Heading","attribute_value_mlt":[{"subitem_heading_banner_headline":"原著論文","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"Article","subitem_heading_language":"en"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"52084"},"item_title":"小学校算数科における一次式の乗法の素地指導に関する研究 : 帯分数同士の乗法と図的表現との関連付けを通して","item_type_id":"40003","owner":"41","path":["1730442897964"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2018478","relation_version_is_last":true,"title":["小学校算数科における一次式の乗法の素地指導に関する研究 : 帯分数同士の乗法と図的表現との関連付けを通して"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-06-04T03:12:03.096166+00:00"}
