As a result, the followings are found out as three main characteristics. (a) There is a remarkable difference between the period of \"Life-Unite Learning\" (1945 — 1957) and the period of \"Systematic Learning\" (1958 — 1967) regarding to the teaching and learning contents and their sequences in these areas shown in the Course of Studies. (b) The contents and sequences shown in the Course of Study (1958) has been the prototype of those shown in the following Course of Studies (1968, 1977, and 1989). In the new one (1998), however, we notice that calculations are rather lightened; decimal numbers and fractions are introduced one year later than the before (1989); the using of algebraic expressions with alphabetic letters is shifted from elementary to lower secondary school mathematics. (c) The dealing with equations and inequalities in secondary schools is gradually lightened in recent years.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"日本数学教育学会"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0021-471X","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00285586","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"154"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2000-07-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"7・8","bibliographicPageEnd":"159","bibliographicPageStart":"154","bibliographicVolumeNumber":"82","bibliographic_titles":[{"bibliographic_title":"日本数学教育学会誌"},{"bibliographic_title":"日本数学教育学会誌"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","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":"J-JpnSoc-MathEduc_82-7_154.pdf","filesize":[{"value":"474.5 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2011494/files/J-JpnSoc-MathEduc_82-7_154.pdf"},"version_id":"6cd5d800-1577-4b39-8930-5cb715fbbbf5"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"30052"},"item_title":"Number and Calculations, Number and Algebraic Expressions <Mathematics Education in Japan during the Fifty-five Years since the War.
