Emerging results of the contributing factors to tactile graphics users' performance for each graphics
task.

Role of graphic type
and quality
Bar Graph Variations in how well
students could follow
guidelines to y-axis and
find horizontal key
Some missed answers
were due to technical
skills in following
guidelines
Third question involved
calculations- there was
variation in student skill
and motivation on this item
Considered good overall
by students; horizontal
key was a challenge for
some with vertical key
considered easier
Venn
Diagram
Students with faster
times were able to find
intersections of the
circles quickly; often
with the two hands
working independently
Faster students knew
where to look for overlap
(experience); most students
were familiar with Venn
Diagrams
Most students liked that
the rings had different
textures, a couple found
this confusing. A
suggestion was made to
have a key for the circles
vs. labels on the outside
of the rings
Shape
Rotation
Use of the pivot point in
relation to the pointed
part of the shape was the
predominant strategy;
one student physically
turned the page, most
did it mentally
The only student missing
the question forgot the
direction of clockwise
saying, "It has been awhile
since I have looked at a
clock." (content
knowledge)
Students considered this a
good graphic overall.
Main suggestion was to
put the letter choices for
the options closer to the
option
