Presentation Transcript

Issues
Issues

  • Accessing books/problem sets

  • Doing homework/tests

  • Getting information in class



Suggestions for instructors
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



Software
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
MathTalk

  • http://www.mathtalk.com/ OR

  • http://metroplexvoice.com/


Books on screen
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



Verbalize
Verbalize

  • Instructor side

    • Concrete, specific descriptions

    • Verbalize equations and operations

  • Student side

    • Verbalize the process

    • Have students explain patterns they see


Strategies
Strategies

  • Spread one semester courses over two

  • Teach strategies, not just algorithms

  • Tactile graphs

  • Manipulatives

  • Color highlighting

  • Draw pictures


Self help
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
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
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
Please Note

  • Many LD students do not find hearing problem sets helpful

  • HOWEVER, many LD students find hearing word problems extremely helpful!

  • Keyboard entry

    • Scientific Notebook

    • MathType

      • Equations can be enlarged

  • Voices what is written

    • Chatty Infty

    • http://www.inftyreader.org/


Creating large print
Creating Large Print

  • Start with PDF

  • Crop pages

  • Print to fit page (11 in. x 17 in.)

  • Can tile pages

    • Portion of page enlarged to full sheet


Enlarging math in word
Enlarging Math in Word

  • Create a “Preferences” file

    • Can save multiple preference files

  • Apply preferences

  • Enlarge text with Ctrl + Shift + >



Be wary of assumptions
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
Nemeth Braille Example

  • Numbers

    • 1234567890

    • #1234567890

  • Symbols

    • x² + 2x + 2 = 10

    • x^2"+2x+2 .k #10


Use meaningful words
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
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
Braille options

  • 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


Lots of math in braille
Lots of Math in Braille!

  • Alternate Text Production Center (ATPC)
