Abstract:Fizika je naravoslovna znanost, ki se ukvarja z eksperimentalnimi raziskavami in matematičnim opisom pojavov v naravi. Ena izmed vej fizike pripada kvantni fiziki, ki opisuje obnašanje "mikroskopskega sveta", kjer prevladuje popolnoma drugačno obnašanje v primerjavi s pojavi, ki jih opazujemo v vsakdanjem življenju. V kvantnem svetu srečamo številne zakonitosti, ki nimajo klasičnih analogij. Zgled "čudnega" obnašanja predstavlja že sama fizika atoma, ki je navadnemu laiku težko razumljiva. Osnovni pojmi, kot so atom, elektron, proton, nevtron ter elektronska ovojnica so nekako razumljivi zaradi obstoja klasičnih analogij. Toda razumevanje merljivih količin, kot je na primer spekter atoma, zahteva popolnoma drugačen pristop.Pri poučevanju kvantnih pojavov so na internetu prosto dostopni številni odlični učni pripomočki, predvsem v obliki interaktivnih izobraževalnih apletov. V svojem diplomskem delu predstavljamo dva izobraževalna apleta, ki nazorno prikazujeta fiziko atoma. Prvi izobraževalni aplet "Model vodikovega atoma" nazorno predstavlja zgodovinski razvoj interpretacije o zgradbi atoma, drugi izobraževalni aplet "Kvantna vezana stanja" pa predstavlja potencialne jame z energijskimi nivoji, v katere se ujame delec – elektron. V diplomskem delu je tako najprej predstavljena zgodovinska pot, ki je vodila do pravilnega opisa obnašanja atoma. Sledi predstavitev osnovnih matematičnih izpeljav, ki podpirajo vsebino izobraževalnih apletov. Nato poudarimo in opišemo ključne korake delovanja aktualnih izobraževalnih apletov.

Title:Use of educational applets to present quantum behavior of atoms
Abstract:Physics is natural science that deals with experimental research and mathematical description of natural phenomena. One of the branches of physics is quantum physics, which describes the behaviour of microscopic world, where prevailes totally different behaviour in comparison with phenomena which we can observe in our everyday life. In quantum world we come across many legalities that do not have classical analogies. The example of strange behaviour is physics of an atom alone, which an ordinary layman find it hard to understand. Basic concepts such as atom, an electron, a proton, a neutron, an electronic envelope are in a way understandable because of an existence of classical analogies. Understanding of measurable quantities, such as spectrum of an atom, requires totally different approach. When teaching quantum phenomena, many available excellent teaching tools can be found on the internet, especially in the form of interactive educational applets. In our thesis we represent two educational applets, which clearly show the physics of an atom. The first educational applet a "Model of the hydrogen atom" clearly shows historical development interpretation about structure of an atom, the second educational applet "Quantum bound states" represent potential walls with energy levels in which a particle is caught – an electron. In the thesis a historical path that led to the correct description of behaviour of an atom is represented first. Representation of basic mathematical carrying outs that support the content of educational applets follows. Then we stress and describe key steps of working of actual educational applets.
Keywords:Quantum physics, spectrum of an atom, potential walls, energy levels, electron, teaching tools, educational applet
