Thomas devised Stemtap, a suite of technologies that makes the teaching of STEM subjects easier, as part of a 2015 University of Adelaide engineering project. Further research by the Stemtap team revealed the supply of STEM graduates is not meeting the demand, and educators are increasingly teaching outside their field. Stemtap consists of hardware that high school teachers who are not tech-confident can easily connect to a program that teaches maths, science and technology in an engaging way. Stemtap’s first project, which helped students learn coding by designing a set of local traffic lights, was a hit with students in the test phase. Thomas is using his grant to manufacture the hardware and prepare the product for national release.
