Abstract

Razumijevanje učeničkih poteškoća ima važnu ulogu za unaprijeđenije kvalitete nastave fizike. Gradivo poput valne optike pred učenike stavlja vrlo apstraktne i zahtjevne pojmove i pojave, koje učenici nisu imali prilike sresti u svakodnevnom životu. Motivirani tom činjenicom, proveli smo kvalitativno istraživanje na devet učenika četvrtih razreda opće i prirodoslovno-matematičke gimnazije u Zagrebu kako bismo provjerili njihovo znanje i razumijevanje valne optike nakon redovite nastave o toj temi. Istraživanje je provedeno u obliku polustrukturiranih intervjua, a obuhvaćalo je teme polarizacije, interferencije iz dvaju izvora i na optičkoj rešetci i ogiba na pukotini. Rezultati istraživanja su analizirani, grupirani po poteškoćama te uspoređeni s ranijim istraživanjima provedenim na Sveučilištu u Washingtonu. Ustanovljene ključne poteškoće vezane za koncepte interferencije, ogiba i polarizacije svjetlosti sugeriraju da bi za ovu temu bila važna istraživački usmjerena nastava, u kojoj pokusi imaju glavnu ulogu. Iako smo pronašli poteškoće koje su se pojavile i u istraživanjima provedenima u drugim zemljama, otkrivene su i neke nove poteškoće. Poteškoće su objasnjene i grupirane, a popraćene su i učeničkim citatima iz intervjua i crtežima.

Abstract (english)

Understanding students’ conceptions and difficulties has a very important role for improving quality of physics teaching. Wave optics concepts are very abstract and complex, and they are not a part of student’s everyday life. Motivated with the aforementioned facts, we conducted a qualitative research on nine high school students from one general type gymnasium and one gymnasium specializing in science and mathematics from Zagreb. We tested students’ knowledge after they had completed regular classes on wave optics. The research was conducted in the form of semistructured interviews that included topics of polarization, double slit and optical grating interference, and single slit diffraction of light. The results were analyzed, classified by students’ difficulties and compared with the previous research of the group at the University of Washington. The identified students’ main difficulties related to the concepts of interference, diffraction and polarization suggest that inquiry-based teaching, in which experiments play a central role, would be important for the teaching of wave optics. In addition to the student difficulties found in previous studies, several new difficulties were also found. Student difficulties were classified, explained and accompanied by students’ quotes and drawings from the interviews.
