Krize ontologie – výzva edukace by Michal Černý

“…Studie se opírá o Kuhnův model vývoje vědy a vychází z něj v analýze dvou – v prostředí školy existujících – fenoménů, totiž globální ekologické krize a formování identity, ve kterých důraz na entitní pojetí vede k nemožnosti se s těmito fenomény vypořádat. Závěrečná část studie upozorňuje na vybrané konceptualizace, které vedou k možnosti opuštění pouze atomistické redukce ontologického popisu světa a nabízejí perspektivy více multiparadigmatického, procesuálního chápání edukace. …”
