Abstract

Valna optika je područje fizike s kojima učenici i studenti imaju dosta poteškoća. Edukacijska istraživanja u fizici su pokazala da uporaba različitih reprezentacija u nastavi može pomoći u razvoju dubljeg razumijevanja fizikalnih koncepata. Cilj ovog diplomskog rada je ispitati mjerenjem pokreta očiju učinak uporabe različitih reprezentacija u nastavi na konceptualno razumijevanje valne optike kod studenata. Mjerenje se sastojalo od predtesta, intervencije i posttesta. Rezultati su pokazali kako je intervencija poboljšala postotak točnih odgovora na posttestu, a smanjilo se i vrijeme rješavanja na posttestu. Studenti su najbolje riješili zadatke s matematičkim reprezentacijama što pokazuje da su neki od njih znali formule, ali ih nisu znali primijeniti u zadacima s grafičkim, slikovnim ili verbalnim reprezentacijama. Mjerenja pokreta očiju su pokazala da su studenti najdulje rješavali zadatke s grafičkom reprezentacijom, a prosječna duljina fiksacija je bila najdulja za slikovnu i grafičku reprezentaciju što pokazuje da je studentima bilo teže izdvojiti potrebne informacije iz tih reprezentacija. S druge strane, verbalna reprezentacija se čini najlakša za studente jer je trajanje fiksacija bilo najkraće. Diskutirani su dobiveni rezultati i koje su njihove implikacije za nastavu fizike.

Abstract (english)

Wave optics is an area of physics with which pupils and students have a lot of difficulties. Physics education research has shown that the use of different representations in teaching can help develop a deeper understanding of physical concepts. The aim of this diploma thesis is to examine the effect of using different representations in teaching on students' conceptual understanding of wave optics by measuring eye movements. The measurement consisted of a pretest, an intervention, and a posttest. The results showed that the intervention improved the percentage of correct answers on the posttest, and the solving time on the posttest also decreased. Students solved best problems with mathematical representations, which shows that some of them knew the formulas, but did not know how to apply them in problems with graphic, pictorial, or verbal representations. Eye movement measurements showed that students solved for the longest time problems with graphic representation, and the average fixation duration was the longest for pictorial and graphic representation, which shows that it was more difficult for students to extract the necessary information from these representations. On the other hand, verbal representation seems to be the easiest for students because the duration of fixation was the shortest. The obtained results are discussed and what are their implications for teaching physics.
