The purpose of this study is to propose a way for teaching models of light to upper secondary students. Even if the subject seems to be at the heart of modern physics, it is too difficult to be taught. This triggered us to design and apply a didactical approach, the evaluation of which seems to be beneficial for the instruction of this topic. Our instruction leads to better student’s comprehension of the nature of light than traditional instruction. The didactical approach, which is a proposal for scientific to educational models transformation concerning light, was applied during the school year 2016-2017 to forty seven (47) students – Experimental Group (EG) - of Upper Secondary Education in Athens. As control group (CG), teaching with the classic way, we have fifty (50) other students. In this paper, it is presented the main research. We describe the teaching method and laboratory experiments in this computer supported attempt. Results and some general conclusions from the statistical analysis of pre, post and final tests are also cited.
