Acesso em:.1982-5374https://repositorio.ufpa.br/handle/2011/12966In this text we aim to discuss the concepts of knowledge and professionalization, and how they are expressed in educacional debate. In different recent documents the presence of concepts such as knowledge society, immaterial labour, professionalization and adaptation has been common, though with a distinct emphasis. The secondary school has been the subject of a series of legal measures that, among other things, proclaim the purpose of citizenship and professional training. Several issues have assumed a prominent position in this debate and in their regulatory processes. Another issue that grabs attention is the presence of culturalist conceptions guiding the debate about secondary school.Acesso Abertohttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Ensino médioConhecimentoProfissionalizaçãoSecondary schoolKnowledgeProfessionalizationArtigo de Periódico10.18542/rmi.v11i16.5386
