The System for Conceptualizing Spatial Concepts or, (SC)2, is an instructional tool developed within my chemistry classes at the New Mexico School for the Blind. By utilizing a system of beveled and magnetized blocks affixed to a magnetic white board, (SC)2 allows students with visual impairments to spatially arrange, manipulate, and calculate complex mathematical and scientific formulae by simply inserting 3 x 5 cards that students have brailled with values and labels of each term. It provides individuals with visual impairments equal access and participation in the classroom while encouraging higher order thinking and greater scientific and mathematical literacy for blind students.
