  2. INTRODUCTIONThe Learning Relationship Instructor Instructional Pathway Assessment Pathway Student

  3. Instructional PathwaysCommon Forms Instructor Classroom Instruction Textbook Website CMS Study Sheets Student

  4. Instructional PathwaysCommon Problems for Math • Text Books – common OCR applications ignore math; publisher PDFs use images • Study Sheets – similar issues to textbooks; sometimes also handwritten • Web sites and CMS – math equations on the web typically are images • Classroom Instruction – how to take accessible math notes?; math verbalization not standard

  5. Assessment PathwaysCommon Forms Student Online Activities Tests Quizzes Homework Papers Instructor

  6. Assessment PathwaysCommon Problems for Math • Tests & Quizzes – special treatment needed for AT to work; students with handwriting issues • Papers – problem of accessible entry of math equation in word processing applications • Homework – problem of sighted teachers and blind students being able to use same formats • Online Activities – how to put accessible math equations on the web; web based math editors?

  7. Instructional PathwaysCommon Solutions for Math Math Textbook Hard Copy Braille RFB&D Recorded E-text Synthetic Speech E-text Braille Display Student

  8. inftyreader.org • InftyReader • Math OCR software • Data conversion • InftyEditor • Editor of math documents • ChattyInfty • InftyEditor + speech output • Authoring and editing tool of math documents for visually impaired users

  10. www.dessci.com/mathtype MathType • Commonly used mainstream WYSIWYG math editor • Works well as math handwriting accommodation • Provides for GUI, keyboard or LaTeX math entry • Exports and imports MathML or LaTeX • Can be used with DBT or Tiger to create Nemeth braille • Issue: Not a natively accessible editor with JAWS • Issue: Equations in Word documents must be exported for use with synthetic speech or braille

  11. www.dessci.com/mathplayer MathPlayer • Commonly used mainstream add-on for IE • Allows web pages or local files containing MathML equations to be displayed in IE • Acts as a transparent accessibility linkage between IE and assistive technologies • After installation requires no user intervention • Works with many AT applications: JAWS, WindowEyes, TextHelp R&W or BA, Serotek

  12. www.dessci.com/mathdaisy MathDaisy • Requires MS Word, MS Save As DAISY add-in, and MathType. • Adds "Save As DAISY" to Word's File menu • Saves document as a DAISY Digital Talking Book with MathML equations

  13. Braille • All braille uses the same 63 symbols • Context gives meaning • Seven braille codes • Each code is slightly different • Uncontracted braille • Contracted braille • Nemeth math braille • CBC (computer braille code)

  14. Bottom Line • Not all students who read braille read Nemeth math braille • Be sure to ask! • Reality check: If the student does not know Nemeth, s/he is unlikely to learn it just to take a math class.

  15. Nemeth Braille Example • Numbers • 1234567890 • #1234567890 • Symbols • x² + 2x + 2 = 10 • x^2"+2x+2 .k #10

  16. Creating Math Braille • Use MS Word with MathType • Or use Scientific Notebook • Use MathType to create equations • Use styles in MS Word • Body text, normal • Headings 1-3 • List, list bullet, list number • Index

  17. Reality Check • Nemeth created with MathType (or Scientific Notebook) may have significant errors • Have the book done by a Nemeth transcriber • Try doing handouts in-house • Check with your student to make sure the braille is acceptable

  18. Nemeth Braille Resources • American Printing House for the Blind hosts the Louis Database • Anyone can search for Braille materials • www.aph.org • ATPC • Sell Braille to all systems • www.atpc.net • Hadley School for the Blind • Free courses • www.hadley-school.org/Web_Site/2_b_ae_and_hs_program.asp

  19. Scientific Calculator • Orion TI-36X • Hand-held, talks • American Printing House for the Blind www.aph.org • MaxiAidswww.maxiaids.com

  20. Other Calculators • www.maxiaids.com • Search on “calculator” • www.softpedia.com • Software, simple talking calculator, free • www.readingmadeez.com • Talking calculator for Windows and Mac • www.r-project.org • Accessible stats calculator

  21. Software Calculator • Audio Graphing Calculator • Computer software, talks • ViewPlus Technology www.viewplus.com • Note: Graphs can be printed on Tiger Embosser or to PIAF paper
