Chemistry teaching method with organic structures for visually impaired students

摘要

method of teaching chemistry with organic structures for visually impaired students the present invention deals with the development of didactic material of 3d models of ball-dipstick structures with braillian spelling, proposed to promote the direct interaction of visually impaired or low vision, with no with visual aids. The didactic material allows the idealization of the structures represented only in the plane in photos or figures in the books, aiming at the understanding of the angle, the types of chemical bonds and nomenclatures necessary for the chemistry learning.
