3D prints assist in teaching blind students
A few educators in the United States have come up with a new technology that turns abstract ideas into teaching aids for blind children.
The educators have used 3D printers to create models to help blind students learn difficult math and science concepts.
Tactile maps use raised symbols, Braille and outlines of structure to help the blind to navigate a space.
The group also came up with ideas like building 3D printed maps of places, simple math models like rulers and protractors.
The idea is to create a new style of co-operative learning between blind students and teachers.
