[Blindmath] Seeking Field Evaluators for Tactile Algebra Tiles

[Li Zhou]

Dear teachers of students with visual impairments:

    APH is seeking field evaluators for Tactile Algebra Tiles. Algebra
tiles is a well-known mathematical tool that provides students with
concrete models for abstract algebraic concepts and procedures. The
tiles can represent both variables and constants and can be used by
students in elementary through high school for adding, subtracting,
and multiplying integers, simplifying expressions, solving linear and
quadratic equations, and for adding, subtracting, multiplying, and
factoring polynomials. The tiles provide the student with an
alternative to abstract manipulation by giving them a graphical way to
solve algebraic problems. In this way, the tool helps meet the
students’ diverse needs in algebra study. The Tactile Algebra Tiles is
an accessible version of algebra tiles, specifically designed for
students with blindness and low vision.

    Field evaluators will be asked to use Tactile Algebra Tiles with
multiple math students with blindness or low vision. Evaluators will
then complete and return a product evaluation form at the end of the
testing period. Field test sites will be selected based upon
geographic location, number of available students, and type of
instructional setting. The field test will begin in January and be
completed by the end of April 2016.

    If you are interested in serving as a field evaluator, please
provide the following information:

a. your name, title, school/agency, and type of setting (e.g.,
residential, itinerant);

b. your previous experience with algebra tiles (e.g., have you ever
used algebra tiles to teach or learn any math concepts);

c. number of available students with ages, grade levels, and primary
reading media indicated (please note that elementary, middle, and high
school students who are studying basic calculations, linear or
quadratic equations, or polynomials are preferred);

d. your preferred medium for reading evaluation materials and
completing the evaluation form (regular print/large
print/braille/electronic); and

e. your complete contact information (phone number, mailing address,
and e-mail address).

    Please send this information to Li Zhou, Core Curriculum Project
Leader, at lzhou at aph.org by December 31, 2015. You may also contact Li
