を満たすa,b,c の値の組を見つけることはできてはいるが，文字式に含まれている文字の値に着目することに止まり，式をプロダクト化できず，ひとまとまりとみることができていない生徒が一定数存在することが明らかとなった．また，一旦，プロダクトの見方によって式をひとまとまりと見ることができても，それをプロセス化することができない実態も浮かび上がった．このことから，数学の学習を重ねていても，式をひとまとまりとみることができない生徒が一定数存在することが明確になり，この困難性を意識して指導する必要があることが明らかとなった．","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34429/0002000141","subitem_identifier_reg_type":"JaLC"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"山梨大学教育学部","subitem_publisher_language":"ja"}]},"item_2_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA12782269","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2433-0418","subitem_source_identifier_type":"PISSN"}]},"item_2_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_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-03-15"}],"displaytype":"detail","filename":"24330418_34_63-74.pdf","filesize":[{"value":"1.5
