The Sound of Fractions

Abstract:

The Sound Of Fractions is an educational environment for students in middle schools mathematics who have not yet understood fractions as a system of parts and wholes. The interface animates multiple representations in auditory and visual modalities, allowing entries through tapping as well as more standard drag and drop and selection methods. Novel elements of the design mediate between an embodied musical notion of parts and wholes and standard mathematical representations like pies, blocks and number lines, now allowing both complement and contrast in questions.
