Teaching a core CS concept through robotics

We implemented single-session workshops using the Thymio-II--a small, self-contained robot designed for young students, and VPL--a graphical software development environment based upon event handling. Our goal was to investigate if the students could learn this core computer science concept while enjoying themselves in the robotics context. A visual questionnaire was developed based upon the combined Bloom and SOLO taxonomies, although it proved difficult to construct a questionnaire appropriate for young students. We found that--despite the short duration of the workshop--all but the youngest students achieved the cognitive level of Unistructural Understanding, while some students achieved higher levels of Unistructural Applying. and Multistructural Understanding and Applying.
