Abstract
Photosynthesis is the most important biochemical process on Earth. Most living beings depend on it directly or indirectly. Knowledge about photosynthesis enables us to understand how the world functions as an ecosystem and how photosynthesis acts as a bridge between the non-living and living worlds. It is, therefore, understandable that photosynthesis is included in national curricula around the world. The practice unfortunately shows that students at all school levels mostly learn about photosynthesis by rote. Consequently, they have difficulties understanding this vital process. Research also shows many misconceptions in relation to photosynthesis among students of different ages. Based on these, the main aim of our study was to explore the scientific conceptions about photosynthesis held by primary school pupils and student teachers of biology. Data were collected using a questionnaire containing seven biology content questions. The sample consisted of 634 participants, 427 primary school pupils (aged 11–14), and 207 student teachers of biology (aged 20–23). We found that the populations of primary school pupils and student teachers of biology differ greatly concerning scientific conceptions of photosynthesis. The student teachers showed good and complex understanding of photosynthesis, while pupils showed some misconceptions (location of chlorophyll and photosynthesis in a plant, transformation of energy in photosynthesis). Analysis of the development of scientific conceptions about photosynthesis with age showed that there is very little progress among primary school pupils and none among biology student teachers. More involvement of student teachers of biology in practical work at primary schools during their study was suggested to make student teachers aware of, and better understand pupils’ misconceptions.

Title:Znanstvena pojmovanja o fotosintezi pri učencih osnovne šole in bodočih učiteljih biologije
Abstract:
Fotosinteza je najpomembnejši biokemični proces na Zemlji. Od nje je posredno ali neposredno odvisna večina živih bitij na Zemlji. Poznavanje fotosinteze nam omogoča, da razumemo, kako deluje svet kot ekosistem ter kako fotosinteza deluje kot most med neživim in živim svetom. Zato je razumljivo, da je fotosinteza vključena v nacionalne učne načrte široko po svetu. Praksa žal kaže, da se učenci na vseh stopnjah izobraževanja fotosintezo večinoma učijo na pamet. Posledica tega je, da imajo težave pri razumevanju tega pomembnega procesa in da ne morejo uporabljati pridobljenega znanja. Raziskave kažejo tudi številna napačna pojmovanja, povezana s fotosintezo, ki jih imajo učenci različnih starosti. Izhajajoč iz tega, je bil glavni cilj naše študije raziskati znanstvena pojmovanja o fotosintezi med učenci osnovne šole in bodočimi učitelji biologije. Podatke smo zbrali z vprašalnikom, ki je vseboval 7 vprašanj. Vzorec je sestavljalo 634 sodelujočih, 427 učencev osnovne šole (starih 11–14 let) in 207 bodočih učiteljev biologije (20–23 let). Ugotovili smo, da se populaciji osnovnošolcev in bodočih učiteljev biologije med seboj zelo razlikujeta glede znanstvenih pojmovanj o fotosintezi. Bodoči učitelji biologije so pokazali zadovoljivo in kompleksno razumevanje znanstvenih pojmovanj o fotosintezi, medtem ko smo pri osnovnošolcih našli nekatera napačna pojmovanja (lega klorofila in poteka fotosinteze v rastlini, energetske pretvorbe pri fotosintezi). Analiza razvoja znanstvenih pojmovanj o fotosintezi glede na starost sodelujočih je pokazala, da je napredka na osnovnošolski stopnji zelo malo, med bodočimi učitelji biologije pa ga sploh ni. Predlagali smo večjo vključenost bodočih učiteljev biologije v praktično delo na osnovnih šolah med izobraževanjem na fakulteti, kar bi prispevalo k zavedanju in boljšemu razumevanju napačnih pojmovanj, ki jih imajo osnovnošolci.
