Dynamic interactive number lines for fraction learning in a mixed reality environment

摘要

Fractions is a challenging mathematical concept for primary school students, since it includes complex conceptual content. The role of the number line as a representational tool for understanding fractions is well established. This paper proposes a new framework for learning about fractions through the use of dynamic interactive and tangible number lines. Our proposal tries to update the static and uncontextualized character of number lines as used in schools or even in educational apps and establish them as useful dynamic mediating tools in authentic environments and for authentic problems. We present a mixed reality environment offering a creative canvas for exercising knowledge about fractions together with a tangible and easily configurable interactive number.
