Improving rational number knowledge using the NanoRoboMath digital game

Abstract Rational number knowledge is a crucial feature of primary school mathematics that predicts students’ later achievement. Many students struggle with the transition from natural to rational reasoning, so novel pedagogical approaches support development are valuable educators worldwide. Digital game-based learning environments may wide range skills. NanoRoboMath, digital environment, was developed enhance conceptual and adaptive knowledge. In this paper, we tested effectiveness preliminary version game fifth sixth grade ( N = 195) using quasi-experimental design. A small positive effect playing NanoRoboMath on observed. Students’ overall performance related outcomes concerning their understanding representations operations.
