Abstract in English, Afrikaans and Zulu / The aim of the study was to develop a critical posthumanist and democratic theory that may be applied in the teaching and learning of Life Sciences in South Africa in order to achieve an expanded form of democracy that would not discriminate between human and nonhuman. Though both critical posthumanist and democratic theories have been used in pedagogical studies separately, this study focused on the development of a merged and broader theory that has elements of both of the theories. The term nonhuman, as used here, does not specifically refer to non-person individuals only. Rather, it also refers to people who are regarded by the dominant humans as nonhumans – inferiors and subalterns. The latter group of people include the poor, women, children, people of colour and the disabled. Owing to this binarisation characteristic of the Life Sciences as a subject – which it adopts from the nature of science, its curriculum, and pedagogical approaches – the impression is given that as the master of the universe, the human has unlimited power over all other entities. These other nonhuman entities are then regarded as resources for the use of humans. Yet, it is this attitude which has caused humans to abuse nonhumans to the extent that the earth is facing the catastrophe of the Anthropocene. The adoption of a critical education approach characterised by the development of a critical posthumanist and democratic theory that may be applied in the teaching and learning of Life Sciences is essential in dealing with the issue of the Anthropocene that is threatening the earth currently. This study thus seeks to adopt a critical education approach through the introduction of democracy into the teaching and learning of Life Sciences, specifically so that humans would get to a position where they would consider nonhumans as entities with which they co-exist, and entities with equal agency within the environment. The recognition of the need for democracy would allow the humans to treat the nonhumans (such as the environment and ‘subalterns’) with respect, as their compatriots; and by doing that, the harrowing issues leading to the catastrophe of the Anthropocene could be either avoided or averted. / Die doel van die studie was om ’n kritiese posthumanistiese en demokratiese teorie te ontwikkel wat op die onderrig en leer van Lewenswetenskappe in Suid-Afrika toegepas kan word om ’n uitgebreide vorm van demokrasie daar te stel wat nie tussen menslik en niemenslik sal diskrimineer nie. Hoewel kritiese posthumanistiese sowel as demokratiese teorieë apart in pedagogiese studies gebruik word, het hierdie studie op die ontwikkeling van ’n saamgesmelte en breër teorie wat elemente van beide teorieë bevat, gefokus. Die term niemenslik soos wat dit hier gebruik word, verwys nie spesifiek net na niepersoon-individue nie. Dit verwys eerder ook na mense wat deur die dominante mense as niemense – minderes en ondergeskiktes – beskou word. Die laasgenoemde groep mense sluit die armes, vroue, kinders, mense van kleur en gestremde mense in. Vanweë hierdie binêre eienskap van die Lewenswetenskappe as ’n vak – wat dit as gevolg van die aard van wetenskap, sy kurrikulum en pedagogiese benaderings aanvaar het – word die indruk geskep dat die mens as heerser van die heelal onbeperkte mag oor al die ander entiteite het. Hierdie ander niemenslike entiteite word dan as hulpbronne vir gebruik deur mense gesien. Dit is egter hierdie houding wat veroorsaak het dat mense niemense misbruik, in so ’n mate dat die aarde die katastrofe van die Antroposeen in die gesig staar. Die aanneem van ’n kritiese onderrigbenadering wat gekenmerk word deur die ontwikkeling van ’n kritiese posthumanistiese en demokratiese teorie wat by die onderrig en leer van Lewenswetenskappe gebruik kan word, is noodsaaklik om die kwessie van die Antroposeen wat die aarde tans bedreig, te hanteer. Hierdie studie wil dus ’n kritiese onderrigbenadering volg deur middel van die bekendstelling van demokrasie by die onderrig en leer van Lewenswetenskappe, in die besonder sodat mense in ’n posisie sal wees waar hulle niemense as entiteite saam met wie hulle ’n bestaan moet voer, en entiteite met gelyke verteenwoordiging in die omgewing, sal beskou. Om die behoefte aan demokrasie te erken, sal die mense toelaat om die niemense (soos die omgewing en “ondergeskiktes”) as hulle landgenote met respek te behandel; en deur dit te doen, kan die pynlike kwessies wat tot die katastrofe van die Antroposeen sal lei, moontlik vermy of afgeweer word. / Inhloso yalolu cwaningo kwakungukusungula umbono obucayi owenziwa ngemuva kokuphila komuntu nentando yeningi engasetshenziswa ekufundisweni nasekufundeni kwesayensi yezempilo eNingizimu Afrika ukuze kuzuzwe uhlobo olwandisiwe lwentando yeningi olungeke lubandlulule phakathi kwabantu kanye nokungebona abantu. Yize zombili izinkolelo ezibucayi ezenziwa ngemuva kokuphila komuntu nezentando yeningi zisetshenzisiwe ezifundweni zokufundisa ngokwehlukana, lolu cwaningo lugxile ekuthuthukiseni kombono ohlanganisiwe futhi obanzi onezici zombili zale mibono. Igama elithi okungebona abantu njengoba lisetshenziswa lapha, alibhekiseli ngqo kubantu abangebona abantu kuphela. Esikhundleni salokho, libhekise nakubantu ababhekwa ngabantu abaphezulu njengabantu abangebona abantu – abaphansi nabasezingeni eliphansi. Iqembu lokugcina labantu lifaka phakathi abampofu, abesifazane, izingane, abantu bebala nabakhubazekile. Ngenxa yalesi sici sokuhlukaniswa kwesayensi yezempilo njengesifundo – emukela emvelweni yesayensi, ikharikhulamu yayo, kanye nezindlela zokufundisa - kunikezwa umbono wokuthi njengomphathi wendawo yonke, umuntu unamandla angenamkhawulo kuzo zonke ezinye izinhlangano. Lezi ezinye izinto ezingezona abantu zithathwa njengezinsiza ukusetshenziswa abantu. Kodwa-ke, yilesi simo sengqondo esidale ukuthi abantu bahlukumeze abantu abangebona abantu kuze kufike lapho umhlaba ubhekene nenhlekelele yokwakhiwa nokuthuthukiswa komhlaba. Ukwamukelwa kwendlela ebucayi yezemfundo ebonakala ngokuthuthukiswa kombono obucayi owenziwa ngemuva kokuphila komuntu kanye nentando yeningi engasetshenziswa ekufundisweni nasekufundeni kwesayenzi yezempilo kubalulekile ekubhekaneni nodaba lokwakhiwa nokuthuthukiswa komhlaba olusongela umhlaba njengamanje. Lolu cwaningo-ke lufuna ukwamukela indlela yezemfundo ebucayi ngokwethulwa kwentando yeningi ekufundisweni nasekufundeni kwesayensi yezempilo, ikakhulukazi ukuze abantu bafike esikhundeni lapho bezobheka khona abantu abangebona abantu njengezinhlangano abaphila nazo, nezinhlangano ezinokumela ngokulinganayo ngaphakathi kwemvelo. Ukwamukelwa kwesidingo sentando yeningi kuzovumela abantu ukuthi baphathe abantu abangebona abantu (njengemvelo kanye nabasezingeni eliphansi) ngenhlonipho, njengabantu bakubo; futhi ngokwenza lokho, izingqinamba ezihlasimulisayo eziholela enhlekeleleni yokwakhiwa nokuthuthukiswa komhlaba zingagwenywa noma zivinjelwe. / Educational Foundations / Ph.
