Math Accommodations Issues Accessing books/problem sets Doing homework/tests Getting information in class Tips for Deaf and Hard of Hearing Students Suggestions for Instructors 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 Software 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!) MathTalk http://www.mathtalk.com/ OR http://metroplexvoice.com/ Books On-screen 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 Verbalize Instructor side – Concrete, specific descriptions – Verbalize equations and operations Student side – Verbalize the process – Have students explain patterns they see Strategies Spread one semester courses over two Teach strategies, not just algorithms Tactile graphs Manipulatives Color highlighting Draw pictures Self-help Work in quiet without clutter Videotape students studying – Students may be totally unaware of what they are doing while studying— videotaping provides feedback Word Problems 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 Auditory Math 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. Please Note Many LD students do not find hearing problem sets helpful HOWEVER, many LD students find hearing word problems extremely helpful!

Can tile pages – Portion of page enlarged to full sheet Enlarging Math in Word Math equations created with MathType 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 Be wary of assumptions 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 Nemeth Braille Example Numbers – 1234567890 –#1234567890 Symbols – x² + 2x + 2 = 10 – x^2"+2x+2 .k #10 Use Meaningful Words 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 In the following example, you would say everything! 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. Braille options Brailling math is expensive and timeconsuming – 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 Lots of Math 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 Other Nemeth Resources 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 Nemeth on Campus 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) Graphics Printer Tiger Embosser – Embosses graphics in raised dots (www.viewplus.com) – Creates Dots Plus math Braille Graphing Requires tactile (distinguishable by feel) accommodations – Tactile diagrams – Manipulatives Tactile Diagrams PIAF paper – “Pictures in a Flash” (www.optelec.com) – Microcapsule paper – Can start from any computer file Other Tactile Strategies Corkboard for graphics – Glue thread to make a grid – Push-pins and string for graphing Magnet boards – Letters and numbers can be purchased – Symbols can be cut from magnetic sheets Be creative!
