Znanje o delcih snovi in agregatnih stanjih na submikroskopski ravni pri devetošolcih v severovzhodni Sloveniji = Knowledge on the particles and state of matter on submicroscopic level in th 9th grade students in northeastern Slovenia : magistrsko delo
Kuronja, Bojana, 1992-
V magistrskem delu je predstavljena raziskava o znanju o delcih snovi in agregatnih stanjih na submikroskopski ravni pri devetošolcih v severovzhodni Sloveniji. Glavni namen magistrskega dela je ...preučiti, kakšno znanje o kemijskih pojmih (element, spojina, zmes, čista snov in agregatno stanje snovi) na submikroskopski ravni imajo učenci v severovzhodni Sloveniji. Prav tako nas je zanimalo, kako se učitelji lotevajo razlage submikroskopske ravni pri pouku, in ali imajo učenci težave pri razumevanju. Za namen raziskave smo pripravili preizkus znanja, ki je bil sestavljen iz petih različnih nalog in je zajemal ključne kemijske pojme. V naši raziskavi je sodelovalo 257 devetošolcev iz šestih osnovnih šol v Mariboru in okolici. Rezultati raziskave so pokazali, da imajo učenci najmanj težav pri prepoznavanju submikroskopske delčne sestave snovi, ki se navezuje na eno spremenljivko (npr. čista snov). Prav tako nimajo težav s prepoznavanjem agregatnih stanj na submikroskopski ravni. Večje težave nastopijo pri prepoznavanju dveh spremenljivk (npr. zmes spojine in elementa, zmes elementov, zmes dveh spojin).
