However these estimated magnitudes of the class size effects are varying and mixed. This paper aims to review the literatures systematically by the meta-analysis. First, we synthesize the previous researches by quasi-experimental design such as instrumental variable regression, regression discontinuity design and difference-in-differences. The estimated mean class size effect is +0.01 SD per student reduction. Second, we analyze the factors of heterogeneities of the class size effect. The nonlinearity of the class size effects and the factor about the policy on teacher salary are examined.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"70383","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hashino, Akihiro"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00031773","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院教育学研究科学校開発政策コース"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1220520X","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13421980","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"370","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Department of School Improvement and Educational Policy Studies, Graduate School of Education The University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"千葉大学"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"橋野, 晶寛"}],"nameIdentifiers":[{"nameIdentifier":"70382","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":"2017-06-12"}],"displaytype":"detail","filename":"eac030005.pdf","filesize":[{"value":"935.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"eac030005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/31782/files/eac030005.pdf"},"version_id":"ed539b1e-4139-4d09-95e4-8094351fbdff"}]},"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":"<個人論文>準実験的手法による学級規模効果研究のメタアナリシス","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"<個人論文>準実験的手法による学級規模効果研究のメタアナリシス"}]},"item_type_id":"4","owner":"1","path":["4354","4353"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-04-12"},"publish_date":"2011-04-12","publish_status":"0","recid":"31782","relation_version_is_last":true,"title":["<個人論文>準実験的手法による学級規模効果研究のメタアナリシス"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:08:05.705024+00:00"}
