In the last decades, a great amount of research has advocated innovating science education through teaching contents of the history, sociology, and philosophy of science in order for the students to get a reliable image of science, significant and relevant learning experiences, and higher interest and engagement in science. Given the embeddedness of techno-scientific systems in contemporary societies, the science-technology-society (STS) movement suggested the simple initiative of teaching science through making explicit the interrelationships between science, scientists, technology, and society to (...) achieve these aims. Since then, the STS tradition has evolved and produced some conceptual variations. This paper deals with three of these variations that are currently the key areas of school science education research and teaching: “socio-scientific issues,” “scientific literacy for all,” and “nature of science.” As heirs of the STS tradition, these mottos embody, at the same time, a clear continuity with STS origins, and some discontinuities, which arise from the development of their own paradigms, adding original elements to the STS movement.
