As We Walked the Beach at GITWL 2009 We Wondered…
Who prepares math materials for learners who use braille and what are their qualifications?
How are math materials prepared for learners who use braille?
What is the quality of the math materials being prepared for learners who use braille?
![Page 3: Quality and Techniques Used When Brailling Math Worksheets Tina Herzberg, Ph.D. University of South Carolina Upstate L. Penny Rosenblum, Ph.D. University.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649cfa5503460f949cb6ee/html5/thumbnails/3.jpg)
Participants had to prepare math materials for students in grades K-12 using Nemeth code.
Participants had to prepare math materials within the last 3 years.
To Participate in the Study…

1st Grade Worksheet (n = 32)
Worksheet contains 27 single digit addition problems set up as a “game.”
The first square on the game board says "START" and the last says "HOME FREE.”
There is a "hint" box that says "Thinking Helps."
Three pictures are on the gameboard that don't tie to the game.

5th Grade Worksheet (n = 21)
This worksheet is titled “Triangles and Quadrilaterals” and contains 12 problems.
The first 9 problems have shapes, and students must classify the shapes and/or find the missing angle.
The final problem shows a flag and asks students to classify colored parts of it.
![Page 9: Quality and Techniques Used When Brailling Math Worksheets Tina Herzberg, Ph.D. University of South Carolina Upstate L. Penny Rosenblum, Ph.D. University.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649cfa5503460f949cb6ee/html5/thumbnails/9.jpg)
Algebra Worksheet (n = 18)
The title of this worksheet is “Skills Practice: Writing Equations in Slope-Intercept Form.”
3 problems contain graphs that show lines on a coordinate plane.
For the other 8 problems students must write equations with the given information.

Geometry Worksheet (n = 15)
The title of the worksheet is “Geometry Practice.”
Worksheet contains a title, directions, and six unnumbered problems.
The first two problems require an understanding of rotation.
The other four problems require the calculation of area and/or perimeter for trapezoids and triangles.

5th Grade Worksheet (n=21)
9 of 21 participants included the print page number in the top right corner.
8 participants used literary page numbers, and 1 used Nemeth.
All participants included angle labels.

All participants included the flag and positioned it properly with clear lines between 3 regions.
18 of 21 participants had 3 regions that were tactually different.
14 of 21 did not use a key. Of the 7 using a key 5 placed it above the flag, one
below the flag and one to the left of the flag. 5 individuals used a lead line from label (e.g. red) to
region.

Algebra Worksheet (n=18)
16 participants who included the 3 graphs included the x-axis and y-axis.
The 16 participants had x-axis and y-axis that were tactually clear.
For the 16 participants the points on the line (e.g., -1, 4) were tactually clear.

Brailling the Origin
It seems unclear if the origin is labeled a zero or letter O in
print.
According to Guidelines and Standards for Tactile Graphics, if the origin cannot be determined in print and there are no numbers on the axes, then label the origin
as the letter O.
![Page 31: Quality and Techniques Used When Brailling Math Worksheets Tina Herzberg, Ph.D. University of South Carolina Upstate L. Penny Rosenblum, Ph.D. University.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649cfa5503460f949cb6ee/html5/thumbnails/31.jpg)
Geometry Worksheet (n=15)
12 out of 15 participants included the grid lines on the graphs.
All participants included the dashed lines, and in 12 instances they could easily be felt tactually.
All 15 participants included the right angles.

Inclusion of braille page numbers All pages = 65% Some pages = 7% No pages = 28%
77% of the time when included, all pages had braille page numbers Most often first page did not have a page number
Location of braille page numbers 45% were placed at the top right 55% were placed at the bottom right

Blank line in a word problem (e.g., A rectangle is ____ a rhombus) 55% of the time used a long dash (4 cells) 37% of the time used a general omission symbol 8% of the time another symbol was used
Omission for a blank line where student is to write an answer 61% of the time no symbol shown 30% of the time used a long dash (4 cells) 9% of the time another symbol was used

85% of the time participants omitted bold, italics or underlining that did not have meaning.
59% of the time when double capitals were used in the print participants used them in the braille.
Formatting Observations
Example:Calculate the area and
perimeter of each triangle below.

88% of the time when graphics were included they looked the way they did in the print.
Not counting the 1st grade worksheet, rarely were graphics left off of the worksheet. 5% left off on the 3rd grade worksheet 1.5% left off on the 5th grade worksheet 11% left off on the Algebra worksheet 1% left off on the Geometry worksheet
Observations of Tactile Graphics
![Page 36: Quality and Techniques Used When Brailling Math Worksheets Tina Herzberg, Ph.D. University of South Carolina Upstate L. Penny Rosenblum, Ph.D. University.](https://reader036.fdocuments.in/reader036/viewer/2022062421/56649cfa5503460f949cb6ee/html5/thumbnails/36.jpg)
84% of the time the elements (e.g., dashed lines, x-axis) were included.
94% of the time labels were included (e.g., angles on a shape, points on a graph).
89% of the time one could tactually feel the elements of the graphic clearly (e.g., crisp lines on graphs).
Observations of Tactile Graphics

Some spatial problems transcribed as linear problems. Order of problems on game board – most followed order of
the problems on the game board, but some did not. They went row by row instead.
There was great variation in what was used as the title of the worksheets.
Some participants did not follow capitalization of the print. There was great variation in the lengths of lines and sizes
of shapes on graphics. Some took an entire page for a simple graphic, and others placed 2-9 simple graphics on a page.
Other Items Noticed During Data Entry

45 almost always proofread their work. 25 out of 59 never have someone proofread
their work, and 17 do so on rare occasions. 36 out of 59 sometimes feel they need
additional support or information. 10 felt they produced excellent quality
science and math materials; 41 felt they produced good quality materials; 7 felt they produced fair quality materials.
