V prispevku je opisana možnost medpredmetnega povezovanja pouka matematike ter tehnike in tehnologije. Namen medpredmetnega povezovanja je teoretične učne vsebine nadgraditi s praktičnim izdelkom in obratno. Prispevek obravnava različne načine računanja prostornine uteži pri matematiki in fiziki v 8. in 9. razredu, ki jo učenci izdelajo pri pouku tehnike in tehnologije v 7. razredu. Namen prispevka je nadgraditi pouk in razširiti učne cilje pri matematiki, ki so učencem zgolj s teorijo težje razumljivi, to je računanje prostornine teles nepravilnih oblik. Pri računanju prostornine uteži so bile uporabljene tako kvalitativne metode dela, in sicer v obliki opazovanja in poročanja, kot kvantitativne, in sicer primerjanje rezultatov in računanje le-teh, pri čemer je bil največji poudarek prav na slednji obliki kvantitativne metode. Učenci so z izvedenimi načini dela spoznali različne oblike merjenja prostornine teles nepravilnih oblik ter s tem ugotovili, da je prostornino slednjih težko natančno določiti. Kot najnatančnejše se je izkazalo merjenje prostornine odlite vode.
Abstract
Measuring and Calculating Volume of Irregularly Shaped Solids
The article explores the possibility of cross-curricular integration between mathematics and design and technology classes. The aim is to enhance theoretical learning content by incorporating practical applications and to strengthen practical skills with theoretical concepts. The article addresses various methods for calculating the volume of a weight constructed in seventh-grade design and technology lessons, in mathematics and physics classes in grades 8 and 9. It discusses the process of creating weights in design and technology classes and examines various methods for calculating their volume in mathematics classes. The aim is to enrich instruction and provide meaningful context for understanding challenging mathematical concepts, which can be difficult to grasp through theory alone. Both qualitative methods (such as observation and reporting) and quantitative methods (including comparisons and calculations) were employed in measuring the weight volume. Through these methods, students became familiar with different techniques for measuring the volume of irregularly shaped solids. While obtaining accurate volume measurements posed a challenge, measuring the volume of displaced water was the most exact.
