How can technological thinking be taught without using technology? We ask this question because of the potential offered by myriad good answers. Most importantly, if significant aspects of technological thinking can be taught without direct recourse to technology, the options for reinforcing such thinking throughout a curriculum can be greatly increased. In fact, simply having a clear idea of what technological thinking is can already make a significant step towards this goal. A further important application is situations, such as developing economies or relatively underfunded education systems, where resources for acquiring technology are inadequate. This paper expands on the approach we have called TNT (Technological Thinking, with No Technology). We survey existing ideas to initiate a concrete list of teachable skills, show how teaching can be based on these skills, and discuss how the TNT mindset is linked to creativity.
