Abstract

je vrlo kompleksna pojava. Da bismo mogli razumjeti elektromagnetsku indukciju, moramo razumjeti i povezati velik broj fizikalnih koncepata, kao što su koncept magnetskog polja, magnetskog toka, magnetske sile, napona i struje. Potrebno je i poznavanje procedura poput primjene pravila desne ruke za određivanje smjera magnetske sile. Učenicima su ti koncepti vrlo apstraktni i teško ih savladavaju. Zbog toga nastaju velike poteskoće u rješavanju problema s elektromagnetskom indukcijom. U ovom su radu prikazani rezultati istraživanja provedenog na 66 učenika trećeg razreda srednje škole, koje je imalo za cilj ispitati učeničko razumijevanje elektromagnetske indukcije i ključnih koncepata magnetizma koji su vezani uz nju. Učenici su rješavali pisani test od osam zadataka uz koje su trebali dati i svoja obrazloženja. Analiza rezultata pokazala je vrlo slabo učeničko razumijevanje ispitivanih pojmova, što upućuje na to da su potrebne značajne promjene u pristupu nastavi elektromagnetizma u srednjim školama.

Abstract (english)

Electromagnetic induction is a very complex phenomenon. In order to understand it, we have to understand and relate a large number of physics concepts, e. g. the concept of magnetic field, magnetic flux, magnetic force, voltage and electric current. Procedural knowledge, such as the application of the right-hand rule for determination of the direction of magnetic force, is also necessary. Students find these concepts too abstract, so it is hard for them to master those concepts. Therefore serious difficulties occur while solving problems related with electromagnetic induction. This paper presents the results of the research of student understanding of electromagnetic induction and related key concepts of electromagnetism which was done on 66 third - year secondary school students. Students were administered a paper-and-pencil test containing eight items which required written explanations. The analysis of the test results indicated very weak student understanding of the investigated concepts and suggested that significant changes in the teaching approach to electromagnetism in secondary schools are necessary.
