“by analyzing elementary school\nteacher data from TALIS2018．\nIn this paper，I used decision tree analysis as the analysis method．By\nusing decision tree analysis，it is possible to extract non-trivial information\nfrom the data．The analysis of constructing hypotheses from previous\nstudies and testing them is often prone to manipulation，but it is expected\nthat decision tree analysis can present findings that have not been obtained\nbefore．Furthermore，decision tree analysis can be read like a flowchart，\nmaking it easy to interpret the results．Therefore，even non-experts can\neasily interpret the results of the analysis，and the knowledge can be\neasily shared between experts and non-experts．\nThe following two findings were obtained from the analysis．（1）The\nsmaller the class size，the shorter the working hours of the teachers．（2）\nThere is no statistical relationship between teachers’working hours and\nthe number of children with low Socio-economic status in their classrooms．\nJapanese schools do not have as many students with economically\ndifficulties，students with limited native language skills，or immigrant and\nrefugee students as their European counterparts．Nevertheless，if the\nworking hours of Japanese teachers are the longest in the world，it is a\nproblem of work culture．Solving “child poverty” is a very important\nsocial problem，however perhaps even if this problem is solved，the\nbusyness of teachers will not go away．A fundamental reconfiguration of\nthe work culture of teachers is needed．","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"桃山学院大学総合研究所"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00240577","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02876647","subitem_source_identifier_type":"ISSN"}]},"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中西, 啓喜","creatorNameLang":"ja"},{"creatorName":"ナカニシ, ヒロキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"12702","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NAKANISHI, Hiroki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"12857","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-02-09"}],"displaytype":"detail","filename":"117_中西啓喜（論文１）.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"中西 啓喜","url":"https://stars.repo.nii.ac.jp/record/9503/files/117_中西啓喜（論文１）.pdf"},"version_id":"a047dc27-90dc-4ed1-b023-b3fa40af05d3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"教師の多忙","subitem_subject_scheme":"Other"},{"subitem_subject":"学級規模","subitem_subject_scheme":"Other"},{"subitem_subject":"TALIS2018","subitem_subject_scheme":"Other"},{"subitem_subject":"データマイニング","subitem_subject_scheme":"Other"},{"subitem_subject":"決定木分析","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":"学級規模縮小は教師の労働時間を短縮するのか？ : 決定木分析を用いたデータマイニングによる検証","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"学級規模縮小は教師の労働時間を短縮するのか？ : 決定木分析を用いたデータマイニングによる検証","subitem_title_language":"ja"},{"subitem_title":"Does Class Size Reduction Reduce Teachers’ Working Hours?：Validated by Decision Tree","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"13","path":["1865"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-02-09"},"publish_date":"2022-02-09","publish_status":"0","recid":"9503","relation_version_is_last":true,"title":["学級規模縮小は教師の労働時間を短縮するのか？ : 決定木分析を用いたデータマイニングによる検証"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-06-19T06:18:10.720351+00:00"}
