From a philosophical viewpoint, technological design is about connecting what is desirable with what is technically possible. Technology itself plays a major role in design processes, not only because technology development is what designing is all about, but also since the existing technology at any given point in time frames what is possible to achieve in terms of new outcomes. A limiting role of technology in design, education and other societal activities goes under the concept of technological determinism and has arguably been one of the most significant points of debate in the social sciences in the last decades. The aim of this article is to investigate how philosophical, sociological and historical research, as well as design and innovation research about technological determinism, could be fruitfully reconsidered in technology education. The analysis yielded three novel findings about the nature of technological determinism. First of all, technological determinism can take the form of an idea, theory or a way of explaining technology development in history or the present, but it can also take the form of actual material structures that-implicitly or explicitly-permeate and influence society, or, at least, this is what some researchers claim. Secondly, technological determinism is not just something that is the result of a bird's eye view of technology and society or when we study technology as part of the macro level of society. Determinism can appear on all levels, even the micro level. Thirdly, like its counterpart social/societal determinism, technological determinism is not necessarily a "bad" thing, but a natural result of design being a balance between what is societally desirable and technically possible. The most critical issue from the point of view of technological literacy is to promote the idea that it is humans that design and retain control over technology.
