In this work we analyze part of the implementation of a didactic sequence [1,2], to teach different aspects of light in a unified non traditional framework. The goal of the sequence was to propose the quantum theory of light as a universal framework to describe different phenomena observed. The sequence was carried out in four courses of two secondary schools, with N=83 students aged 15-16, during 23 school hours approximately. The data analysis, based on all the students? productions, aims to understand the process of student´s conceptualization [4] of Feynman?s viewpoint of quantum mechanics. The results allow to make a preliminary assessment of the viability of the sequence based on this viewpoint and the changes necessary for future implementations.
