Here, Mike Bottery shows how, paradoxically, these forces are making education both more centralized and more fragmented. In this magisterial study of educational policy and practice, he shows the dangers this creates and, in response, how to create a more humane and democratic education system.School management and organizationEducation and stateMoral and ethical aspectsElectronic books.School management and organization.Education and stateMoral and ethical aspects.370.1379.01Bottery Mike931836MiAaPQMiAaPQMiAaPQBOOK9910453594803321Education policy and ethics2175703UNINA05018nam 2200613Ia 450 991013947150332120180613165534.01-282-49158-X97866124915803-527-62991-23-527-62992-0(CKB)2550000000006854(EBL)481259(OCoLC)521036915(SSID)ssj0000353928(PQKBManifestationID)11270485(PQKBTitleCode)TC0000353928(PQKBWorkID)10301976(PQKB)10118182(MiAaPQ)EBC481259(PPN)152220585(EXLCZ)99255000000000685420091027d2010 uy 0engur|n|---|||||txtccrCarbon dioxide as chemical feedstock[electronic resource] /edited by Michele ArestaWeinheim Wiley-VCHc20101 online resource (416 p.)Description based upon print version of record.3-527-32475-5 Includes bibliographical references and index.Carbon Dioxide as Chemical Feedstock;
