This paper discusses some topics that stem from recent contributions made by the History, the Philosophy, and the Didactics of Science. We consider these topics relevant to the introduction of the Special Relativity Theory (SRT) in high school within a contextualized approach. We offer an outline of a teaching-learning sequence dealing with the SRT within this frame of reference. Such a sequence was tried out on a group of high school students in Argentina. The results obtained seem to indicate that the proposal has been effective as regards the motivational aspects and the understanding students gained of some of its concepts.
