This thesis seeks to advance interaction design practice by exploring the potential of interactive tangible prototypes to enhance university students' understanding of abstract programming structures, such as loops. It addresses prevalent challenges, including the difficulties students encounter when initially learning about loops, and scalability issues inherent in tangible teaching tools within this research area. Two distinct tangible learning methodologies are considered: unplugged programming and tangible computing. The primary contributions of this thesis lie in the creation of innovative tangible learning tools, the emphasis on the scalability of such tools, and the illumination of how physical prototypes can inspire digital software design.
