20.500.12556/RUL-181734 A DIY model to support understanding of the phases of the Moon Students often experience difficulties in understanding the phases of the Moon, particularly in relating Earth-based observations to the spatial configuration and motion of the Sun–Earth–Moon system. Persistent misconceptions are well documented. This paper presents a simple, low-cost, do-it-yourself model designed to support conceptual understanding by linking two frames of reference: a heliocentric coordinate system, used to explain the physical origin of lunar phases, and a geographic coordinate system, from which the phases are observed. The model combines a planar representation of orbital motion with a three-dimensional viewing element that enables an Earth-based perspective. By explicitly connecting these viewpoints, the model supports the transition from observation to explanation. The model can be easily constructed from readily available materials and is suitable for use in primary and secondary school classrooms. astronomy education Moon’s phases DIY model hands-on from HCS to GCS perspective lunine faze model za samostojno izdelavo praktično delo astronomija vzgoja in izobraževanje true false true Angleški jezik Slovenski jezik Članek v reviji 2026-04-15 07:10:01 2026-04-15 07:10:02 2026-04-16 04:45:24 0000-00-00 00:00:00 2026 0 0 6 str. no. 2, art. 025038 Vol. 61 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 373:52 1361-6552 10.1088/1361-6552/ae4e0f 275194115 RAZ_Rovsek_Barbara_2026.pdf RAZ_Rovsek_Barbara_2026.pdf 1 F4E5705F40AEEF77CB2EEE2E35024E90 ddb076d8b0724f544edfdb539c4c202de04743bb038769a99128502feee098e2 ba2abbfb-3889-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=232429 https://iopscience.iop.org/article/10.1088/1361-6552/ae4e0f 1 23d0c1d8-3889-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=232428 Pedagoška fakulteta 0 0 0
