Tips for Blind Students

Be wary of assumptions Blindness covers a range Blindness covers a range –Most blind folks have some sight –Many do see color Not all blind people read Braille Not all blind people read Braille –In fact, many CC students do not Not all students who read Braille read Nemeth math Braille Not all students who read Braille read Nemeth math Braille

Nemeth Braille Example Numbers Numbers – –# Symbols Symbols –x² + 2x + 2 = 10 –x^2"+2x+2.k #10

Use Meaningful Words Use concrete terms Use concrete terms Meaningless! Meaningless! –“Here is the equation.” –“We start with the equation and factor.” –“Set both factors equal to zero and solve to get the result.” Avoid Avoid –This, that, here, there, thing

In the following example, you would say everything! Don’t just write it; verbalize it! Say each step. Don’t just write it; verbalize it! Say each step. 6x 2 = 53x + 9 Subtract 53x and 9 from both sides 6x 2 – 53x – 9 = 0 Trinomial factoring gives us (6x + 1)(x – 9) = 0 Set both factors equal to zero 6x + 1 = 0 and x – 9 = 0 Solve each equation…etc.

Braille options Brailling math is expensive and time- consuming Brailling math is expensive and time- consuming –Algebra books can cost $25,000+ –Calculus books can cost $100,000+ Check books already in Braille and see if instructor is willing to use the problem sets Check books already in Braille and see if instructor is willing to use the problem sets Work with an instructor on “independent study” with a book already in Braille Work with an instructor on “independent study” with a book already in Braille

Lots of Math in Braille! Alternate Text Production Center (ATPC) Alternate Text Production Center (ATPC) – ATPC produces Braille and tactile graphics free for the CCCs ATPC produces Braille and tactile graphics free for the CCCs –Sells books to those outside CCC system Must have syllabus to begin project Must have syllabus to begin project –They braille only required chapters –The more advance notice, the better
