The Evolving Design of Tangibles for Graph Algorithmic Thinking

Abstract

Algorithmic thinking is at the core of computational thinking. Tangible interactive solutions can help children develop algorithmic thinking skills. This paper focusses on exploratory research concerning tangibles for graph algorithmic thinking for primary and middle schools. By following an action-research process, tangibles evolved through prototyping and actions-studies. The paper overviews their evolution and delves into its most recent action: an ecological study with 8 middle school children, and 5 primary school children, using tangibles for graph algorithmic thinking. It ends by reflecting on results and future work.
