The history of technology can play an important role in illuminating the fundamentals of technological change, but it is important that technology teachers, teacher educators, curriculum developers and researchers can be provided with good analytical tools for this purpose. In this article, we propose a model of techno-historical interplay, as a help in deciding what historical artefacts and systems should be included in technology curricula and teaching as well as in analyzing and conveying to students the fundamental issues of technological change. We want to emphasize particularly three points of importance in employing the model as a tool of analysis. First of all, it is crucial to decide what one wants the technologically literate student to know about technology and technological change. This should include an awareness of the historical and geographical contingency of any technology. Second, on the basis of this decision one should adapt the model as a tool for selecting relevant technologies. Third, the model should be applied as an instrument of analysis of the history of the selected technological artefacts or systems as well as theories of technological development.
