Vpliv raziskovanja spolne selekcije na razumevanje evolucije pri osnovnošolcih
Povzetek
Več raziskovalcev in znanstvenih ustanov trdi, da je treba evolucijo raziskovati že v prvih šolskih letih, vendar pa je malo študij analiziralo razumevanje evolucijskih procesov pri osnovnošolcih ali ovrednotilo vpliv izobraževalnih dejavnosti na tako znanje. Razpoložljivi podatki: i) nakazujejo, da se osnovnošolci lahko učijo o evoluciji; ii) opredeljujejo diferencialno reprodukcijo kot ključni koncept evolucije, ki ga učenci redkeje uporabljajo za navedbo in utemeljitev evolucijskih napovedi. V tej študiji ocenjujemo vpliv izobraževalnega programa na raven razumevanja osnovnošolcev glede evolucije s spolno selekcijo in na njihovo sposobnost uporabe diferencialne reprodukcije za predlaganje in utemeljitev evolucijskih napovedi. Pri tem je bilo uporabljeno evalvacijsko ogrodje za oceno stopnje razumevanja evolucije s spolno selekcijo osnovnošolcev v oddelkih tretjega in četrtega razreda, pred tem in po tem, ko so bili učenci izpostavljeni izobraževalnemu programu. Znatno povečanje stopnje razumevanja evolucije s spolno selekcijo so opazili v ciljnih, ne pa tudi v kontrolnih razredih. Ta rezultat je bil predvsem posledica znatnega povečanja utemeljitev učencev, ki uporabljajo koncept diferencialne reprodukcije. Izsledki kažejo, da lahko dejavnosti, ki modelirajo in simulirajo biološko evolucijo s spolno selekcijo, prispevajo k razumevanju evolucijskih procesov pri osnovnošolcih.
