Secondary title:	Hardness and stress concepts understanding of 6th-8th grade pupils in primary school
Secondary abstract:	Design and Technology curriculum in primary school (y 12-14) encompases also physical and mechanical properties of design. When dealing with different materials such as wood and paper in the sixth class, plastics materials in the seventh class and metals in the eighth class, students learn about the properties of materials. In the mechanical properties of materials, students encounter the concepts of hardness and stress. Both terms are presented and explained thoroughly in this work. The methods of their specification / testing and various influences (temperature, time, radiation) that affect the quality of the measurement of individual material properties (hardness and stress) are given. There is a thorough presentation of construction concept, what the word construction is and what falls under that concept. A link between construction and the concepts of hardness and stress is also described. Students’ understanding of all three concepts (from 6th to 8th class) has been found by the survey. We researched whether the students’ sex, their school certificate and elective subjects related to Design and Technology affect their understanding of the concepts. This work gives suggestions to the teachers of Design and Technology how to improve the understanding of the concepts of hardness, stress and construction in the classes 6-8 of elementary school. The suggestion also includes a didactic accessory for testing hardness and stress of materials, a worksheet for checking the pupils’ knowledge, demonstrations of experiments, which can be done during the lessons and a questionnaire for the teachers to check their understanding of the concepts of hardness, stress and construction, which they teach.

Abstract (ePrints):	V devetletni osnovni šoli je v učnem načrtu predmeta tehnika in tehnologija zajeto obravnavanje fizikalnih in mehanskih lastnosti materialov. Pri obravnavi različnih materialov, kot so les in papir v 6. razredu, umetne snovi v 7. razredu in kovine v 8. razredu, se učenci srečajo z obravnavo lastnosti posameznih materialov. Pri mehanskih lastnostih materialov se učenci srečajo s pojmoma trdota in trdnost. Oba pojma sta v delu podrobno predstavljena in pojasnjena. Podani so načini njunega določevanja/preizkušanja ter različni vplivi(temperatura, čas, radioaktivno sevanje), ki vplivajo na kvaliteto merjenja posameznih lastnosti (trdote in trdnosti) materialov. Podrobno je predstavljen tudi pojem konstrukcije, kaj beseda konstrukcija predstavlja in kaj vse spada pod ta pojem. Opisna je tudi povezanost konstrukcije s pojmoma trdote in trdnosti. Razumevanje vseh treh omenjenih pojmov med učenci (6.-8. razred) je bilo ugotovljeno s pomočjo anketiranja. Raziskali smo ali na razumevanje pojmov vpliva spol učenca, njihov učni uspeh in izbirni predmet s področja tehnike in tehnologije. Delo podaja predloge učiteljem tehnike kako izboljšati razumevanje pojmov trdote, trdnosti in konstrukcije v 6.-8. razredu osnovne šole. Predlog zajema tudi didaktično učilo za preizkušanje trdote in trdnosti materialov, učni list za preverjanje znanja učencev, demonstracije poizkusov, ki se lahko izvedejo pri urah in vprašalnik za učitelje za preverjanje njihovega razumevanja pojmov trdote, trdnosti in konstrukcije, ki jih poučujejo.
