This project will integrate computational thinking and electronics concepts in middle and high school classrooms using electronic textiles (e-textiles) projects for students. The content of the projects includes electricity, conductive materials, programming and computational thinking. This project builds on significant work already underway in which e-textiles have been used in out-of-class situations and are beginning the transition to classroom use. The primary implementation activity will be providing professional development to teachers about computational thinking and e-textiles. The project includes scaling up to a large number of teachers. It also includes rural schools in the region of the university. The research and development plan includes collaboration between education faculty and computer science and engineering faculty. As a STEM+C project it nicely integrates computational thinking within the context of science classrooms and presents a model for instruction that could apply to other topics.
