Sampling of this study consists of a total of 110 physics education students who were<br \/>\ntaking a modern physics course at two different state universities in Turkey. As a result, three<br \/>\nmental models, which were called the beam ray model (BrM), hybrid model (HM) and particle model<br \/>\n(PM), were being used by the students while explaining these phenomena. The most model fluctuation<br \/>\nwas seen in HM and BrM. In addition, some students were in a mixed-model state where they use<br \/>\nmultiple mental models in explaining a phenomenon and used these models inconsistently. On the other<br \/>\nhand, most of the students who used the particle model can be said to be in a pure model state.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this study, we investigated pre-service physics teachers\u2019 mental models of light in different<br \/>\ncontexts, such as blackbody radiation, the photoelectric effect and the Compton effect.
