Electromagnetic waves: concepts and applications in physics education

Abstract

Elektromagnetski valovi su u prošlom stoljeću iz znanstvenih krugova došli u krugove sveopćeg puka. Da bi se približili elektromagnetski valovi u današnje vrijeme su se počele upotrebljavati aplikacije kako bi se približilo ljudima te im postalo jasnije. Učenici nakon srednjoškolskog obrazovanja ne barataju dobro s pojmovima i konceptima vezanim uz elektromagnetske valove, nego sa striktno napisanim definicijama koje ne znaju upotrijebiti u svakodnevnom životu. Provođenjem ankete vezanom uz elektromagnetske valove i njihove koncepte uvidio sam da akademski obrazovani ljudi i učenici ne znaju osnove, te imaju problema s konceptualnim razumijevanjem elektromagnetskih valova. S obzirom na rezultate istraživanja sam napravio jedan interaktivni sat čime bi se izvođenjem na nastavi fizike doprinijelo učeničkom konceptualnom razumijevanju i vizualizaciji elektromagnetskih valova.In the last century electromagnetic waves came from the scientific community in the circles of common people. Today, we have started to use application with electromagnetic waves so they would become closer and more clear to people. After high school students do not handle with the terms and concepts related to electromagnetic waves, but with strict written definitions which they do not know how to use in everyday life. By conducting surveys related to electromagnetic waves and their concepts it is realized that academically educated people and students do not know the basics and have problems with a conceptual understanding of electromagnetic waves. Considering the results of research, I have held an interactive lesson of physics which would contribute to the student´s conceptual understanding and visualization of electromagnetic waves
