Vključevanje sodobnih znanstvenih spoznanj v pouk naravoslovnih predmetov - predstave o hidrogelih

Abstract

Hidrogeli so atraktivni materiali, ker lahko absorbirajo velike količine vode. Imajo zanimive lastnosti, ki jih zlahka prikažemo s poskusi in ob njih razložimo določene naravoslovne pojme ali pojave. Hidrogeli so razširjeni v prehrambeni, farmacevtski in agrikulturni industriji, a pogovori s študenti kažejo, da redki vedo za njihov obstoj. Hidrogeli so tema, ki jo zlahka vključimo v pouk kemije in fizike v srednji šoli, zato smo si za cilj zadali raziskati predstave o hidrogelih po končanem srednješolskem izobraževanju. V raziskavo so bili vključeni 104 študenti 1. letnika razrednega pouka s Pedagoške fakultete Univerze v Ljubljani. V februarju 2015 so reševali anketni vprašalnik tipa papir-svinčnik, ki je vseboval 26 vprašanj. Rezultati kažejo, da so študenti v povprečju dosegli 0,8 točk od 10 možnih. To kaže na zelo omejeno znanje o hidrogelih. Rezultati raziskave predstavljajo izhodišče za oblikovanje učnega gradiva o hidrogelih.

Secondary title:	Introducing modern topics into teaching of science subjects - conceptions about hydrogels
Secondary abstract:	Attractive materials that absorb large quantities of water are called hydrogels. They have interesting properties which can be easily shown with experiments and combined with explanation of certain science concepts and phenomena. Hydrogels are spread in food, pharmaceutical and agriculture industry. The informal conversations with students show that they are not aware of their existence. Hydrogels can be easily included into teaching of physics in chemistry in high schools, therefore we decided to explore students' conceptions about hydrogels after the high school. 104 pre-service primary school teachers from Faculty of Education, University of Ljubljana, were included into the study. Students filled in a paper-pencil questionnaire with 26 items on February 2015 at the beginning of the spring semester. Students achieved 0.8 points out of 10 on items testing the knowledge about hydrogels. This shows on limited knowledge about hydrogels. Results present the starting point for the designing of the teaching module about hydrogels.
