Computational thinking is a problem-solving technique traditionally employed by computer scientists to develop computer applications. However, computational thinking practices are now believed to be applicable to other fields (Google for Education, 2018), specifically those related to engineering and technology. Accordingly, the Advancing Excellence in P-12 Engineering Education (AEEE) (2018) project identified computational thinking as a core engineering concept to create a foundation for students to conduct the quantitative analyses that engineers and other related professionals perform. Likewise, the Committee for the Workshops on Computational Thinking contends that computational thinking is necessary for people to develop efficient and automated physical design solutions as well as visualizations of design concepts and computational scientific models (NRC, 2011). These abilities, which also include thinking critically about complex problems, generating creative solutions, and communicating solutions effectively, are now considered necessary at all levels of scholarship. This article will provide an example instructional activity for fostering computational thinking while also addressing core engineering concepts in electronics using programmable E-textiles.
