Abstract

Plovnost in z njo povezani pojmi gostota, masa in prostornina naj bi bili učencem v drugem triletju in seveda tudi starejšim popolnoma jasni. Pa žal ni tako. V raziskavi, v katero smo zajeli 88 učencev četrtega razreda ob koncu šolskega leta, torej že po obravnavani snovi, smo ugotovili, da še vedno večina misli, da telo plava, če je "lahko". Zato smo izvedli učno uro, na kateri so učenci s pomočjo učiteljev izvajali eksperimente, s katerimi smo jim poskušali razložiti in nazorno prikazati, da je plovnost odvisna tako od mase kot tudi od oblike predmeta in seveda tudi od gostote tekočine, v katero polagamo ta predmet. Po izpeljani učni uri smo učence ponovno testirali. Iz odgovorov lahko razberemo, da se jih zdaj več zaveda, da je plovnost povezana tako s snovjo, iz katere je predmet, kot tudi z obliko telesa. Do končnega cilja, to je pravilnega razumevanja pojma plovnosti, pa bo treba narediti še nekaj korakov. Osredotočili se bomo na rezultate obeh testov in navedli, kako in katere poskuse smo izvedli in kaj je treba še storiti, da bi pojem plovnosti učenci zares trajno usvojili.

Secondary abstract: Pupils in the second triennium of primary school and older ones should fully comprehend the concept of buoyancy and related terms density, mass and volume. Unfortunately, they do not. We carried out a research with 88 fourth grade pupils at the end of the school year and found out that a common misconception among the pupils is that heavy objects sink and light objects float. Therefore, we conducted a lesson, in which pupils and of their teachers carried out experiments, to explain and clearly demonstrate that buoyancy depends on the mass and shape of an object as well as on the density of a fluid in which the object is placed. After the lesson we tested the pupils again. The results suggest an improvement in pupils' understanding of buoyancy. We still need to take some steps to achieve the final objective, the proper understanding of buoyancy. We will focus on the pre- and post-test results and list how and which experiments were carried out and what still needs to be done to gain a thorough understanding of buoyancy.
