Making Space for Spatial Proportions
Matthews, Percival G.; Hubbard, Edward M.
Journal of Learning Disabilities, v50 n6 p644-647 Nov-Dec 2017
The three target articles presented in this special issue converged on an emerging theme: the importance of spatial proportional reasoning. They suggest that the ability to map between symbolic fractions (like 1/5) and nonsymbolic, spatial representations of their sizes or "magnitudes" may be especially important for building robust fractions knowledge. In this commentary, we first reflect upon where these findings stand in a larger theoretical context, largely borrowed from mathematics education research. Next, we emphasize parallels between this work and emerging work suggesting that nonsymbolic proportional reasoning may provide an intuitive foundation for understanding fraction magnitudes. Finally, we end by exploring some open questions that suggest specific future directions in this burgeoning area. [For the target articles in this special issue, see "Fractions Learning in Children with Mathematics Difficulties" (EJ1157276); "Delaware Longitudinal Study of Fraction Learning: Implications for Helping Children with Mathematics Difficulties" (EJ1157256); and "Fraction Intervention for Students with Mathematics Difficulties: Lessons Learned from Five Randomized Controlled Trials" (EJ1157268).]
