20.500.12556/DKUM-76260 Znanje o delcih snovi in agregatnih stanjih na submikroskopski ravni pri devetošolcih v severovzhodni Sloveniji Knowledge on the particles and the state of matter on submicroscopic level in the 9th grade students in Northeastern Slovenia 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). This master's thesis contains the research about the knowledge of particles and state of matter on submicroscopic level of 9th grade students. Its main purpose is to study the level of knowledge of students in northeastern Slovenia about chemistry concepts on sub-microscopic level. We were also interested how teachers go about and present the topic and if students have issues comprehending it. We created a test consisting of five tasks about chemistry concepts, in order to do our research. We had 257 students taking the test from 6 elementary school in Maribor and surrounding areas. Results have shown that students have the least amount of trouble when it comes to recognizing submicroscopic fractions of matter, when there is only one variable (e.g. pure substance). They also have no issues with recognizing states of matter on submicroscopic levels. They do however have issues when it comes to recognizing two variables (e.g. mixture of compound and element, mixture of elements, mixture of compounds). razumevanje kemijskih pojmov submikroskopska raven element spojina zmes čista snov agregatno stanje snovi. understanding chemical concepts submicroscopic level element compound mixture pure substance state of matter. true true false [B.
