Math Accommodations

- Accessing books/problem sets
- Doing homework/tests
- Getting information in class

Tips for Deaf and Hard of Hearing Students

- Face the students
- Do not talk facing the board

- Repeat student questions
- The deaf student may not have been looking at the questioner

- Make sure you can be seen clearly
- Do not stand and talk in front of a bright window

- Use gestures
- Pointing to what you’re talking about is helpful

- Build in pauses
- Deaf students do a lot of multi-tasking, allow some pauses

Tips for Students with Upper Limb Impairments

- Math equation programs allow keyboard entry
- Scientific Notebook
- MathType (plug-in for Word)

- MathTalk allows voice entry
- Requires MathTalk, Dragon NaturallySpeaking and Scientific Notebook (all three!)

- http://www.mathtalk.com/ OR
- http://metroplexvoice.com/

- Scan to PDF
- Read visually on-screen (no TTS)
- Foot pedal mouse
- Use Dragon to advance pages onscreen
- Remove spine and rebind to lay flat
- Use hardware page-turning systems

Tips for LD Students

- Instructor side
- Concrete, specific descriptions
- Verbalize equations and operations

- Student side
- Verbalize the process
- Have students explain patterns they see

- Spread one semester courses over two
- Teach strategies, not just algorithms
- Tactile graphs
- Manipulatives
- Color highlighting
- Draw pictures

- Work in quiet without clutter
- Videotape students studying
- Students may be totally unaware of what they are doing while studying—videotaping provides feedback

- Learn key words
- “and,” “sum,” “increased” mean add
- “take away,” “difference,” “less” mean subtract
- “of,” “times” means multiply
- “per,” “out of,” “ratio of,” “quotient” mean divide

- Highlight what is important
- Look for key words

- List information
- Draw pictures

- Math books in MathML
- Create in MathType or Scientific Notebook

- MathPlayer reads and highlights
- Free download from Design Science
- http://www.dessci.com/

- Read&Write Gold, Dolphin Tutor, and WYNN work with MathPlayer
- Kurzweil only works from the Web interface.

- Many LD students do not find hearing problem sets helpful
- HOWEVER, many LD students find hearing word problems extremely helpful!

Tips for Low Vision Students

- Keyboard entry
- Scientific Notebook
- MathType
- Equations can be enlarged

- Voices what is written
- Chatty Infty
- http://www.inftyreader.org/

- Start with PDF
- Crop pages
- Print to fit page (11 in. x 17 in.)
- Can tile pages
- Portion of page enlarged to full sheet

- Math equations created withMathType plug-in
- http://www.dessci.com/en/products/

- Create a “Preferences” file
- Can save multiple preference files

- Apply preferences
- Enlarge text with Ctrl + Shift + >

Tips for Blind Students

- Blindness covers a range
- Most blind folks have some sight
- Many do see color

- Not all blind people read Braille
- In fact, many CC students do not

- Not all students who read Braille read Nemeth math Braille

- Numbers
- 1234567890
- #1234567890

- Symbols
- x² + 2x + 2 = 10
- x^2"+2x+2 .k #10

- Use concrete terms
- 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
- This, that, here, there, thing

- Don’t just write it; verbalize it! Say each step.
6x2 = 53x + 9

Subtract 53x and 9 from both sides

6x2 – 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.

- 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
- Work with an instructor on “independent study” with a book already in Braille

- Alternate Text Production Center (ATPC)
- www.atpc.net

- ATPC produces Braille and tactile graphics free for the CCCs
- Sells books to those outside CCC system

- Must have syllabus to begin project
- They braille only required chapters
- The more advance notice, the better

- American Printing House for the Blind hosts the Louis Database
- Anyone can search for Braille materials
- www.aph.org

- Hadley School for the Blind
- Free courses
- www.hadley-school.org/Web_Site/2_b_ae_and_hs_program.asp

- Scientific Notebook documents can be translated into Nemeth math Braille
- www.mackichan.com
- From other equation editors, save as LaTeX
- Take into Scientific Notebook and save
- Open with Duxbury Braille Translation Software (www.duxsys.com)

- Tiger Embosser
- Embosses graphics in raised dots (www.viewplus.com)
- Creates Dots Plus math Braille

- Requires tactile (distinguishable by feel) accommodations
- Tactile diagrams
- Manipulatives

- PIAF paper
- “Pictures in a Flash” (www.optelec.com)
- Microcapsule paper
- Can start from any computer file

- Corkboard for graphics
- Glue thread to make a grid
