Secondary title:	Knitted patterns as a model for anisotropic materials
Secondary abstract:	This thesis introduces anisotropy as a special feature present in many aspects of everyday life and further deals with the presentation of anisotropic properties to students based on application of simple examples. The key to activate students' motivation lies in showing the relation of the subject matter to everyday life experience. Acquiring new subject matter should always be based on a plain and well known example. It should be simple and straightforward in order to highlight each particular property. The process of developing comprehensive knowledge of the subject matter requires full, conscious and active participation of learners in the class work. This thesis also contains a detailed description of some simple experiments which make the presentation of anisotropy easily manageable and understandable. The measurements in these experiments revealed the elastic expansion of different knitted patterns as well as the angles of indentation. The result of processing the measured data using the Microsoft Office Excel programme was the calculation of the elastic constant. I have also incorporated anisotropy as a special topic into the primary school physics curriculum and prepared a worksheet since I believe the simplicity of knitted patterns enables and increases independent and active student participation.

Abstract (ePrints):	Anizotropija je lastnost, ki je pogosto prisotna v vsakdanjem življenju. V tem diplomskem delu jo najprej podrobno predstavim, v nadaljevanju pa se ukvarjam predvsem s tem, kako učencem na čim bolj preprostem primeru pokazati, kaj je anizotropnost. Za pridobitev primerne motivacije učencev je koristno povezovanje učne snovi z vsakodnevnim življenjem učenca. Učenje nove snovi mora temeljiti na primeru, ki je učencem dobro poznan in enostaven. Primer mora biti tudi dovolj preprost in predvsem primeren za razlago in predstavo točno določenih lastnosti. Za poglobljeno znanje učencev je primerno, da so učenci aktivno vključeni v pouk in delo. V delu podrobneje opišem preproste eksperimente, s katerimi bo razumevanje anizotropije jasno in predstavljivo. Z njimi sem izmerila raztezanje različnih vzorcev pletenja, kot zamikanja vzorca in izračunala koeficient elastičnosti. Pri samem delu s podatki sem si pomagala s programom Microsoft Office Excel. Temo anizotropnost sem umestila tudi v učni načrt fizike za osnovno šolo in pripravila učni list, saj so pleteni vzorci dovolj preprosti in primerni za samostojno delo učencev. Hkrati bi bili učenci na tak način aktivno vključeni v pouk in delo.
