ALGEBRAIC STRUCTURE SENSE IN A BLIND SUBJECT

Literature about the way visually impaired students approach mathematics is still very scarce, especially in the case of algebra, despite the fact that mathematical content is known to be increasingly accessible thanks to assistive technologies. This report presents a case study aimed at describing the process of algebraic symbols manipulation by a blind subject. Results show how the hearing can substitute the eye in the development of structure sense. Data analysis reveals that screen readers and coding languages (as LaTeX) have interesting potentialities in the development of structure sense for blind students.
