Preface
The Center on Disabilities at California State University, Northridge is proud to welcome you to
the third issue of the Journal on Technology and Persons with Disabilities. These published
proceedings from the Annual International Technology and Persons with Disabilities
Conference, represent submissions from the Science/Research Track presented at the 30th
anniversary event held March 2-7, 2015.
The Center on Disabilities at CSUN has been recognized for sponsoring an event that for three
decades highlights the possibilities and realities which facilitate the full inclusion of individuals
with disabilities. Over the years it has truly become the major global platform for meeting and
exchanging ideas, continually attracting more than 4,000 participants annually.
We were once again pleased that the third Call for Papers for the Science/Research Track in
2014 drew a large response of more than 40 leading researchers and academics. A panel of more
than 30 highly-qualified peers from around the world formed the program committee and was
chaired by Dr. Klaus Miesenberger. The expertise of the program committee ensured that each
contribution was expertly and equitably peer-reviewed and only those submissions of the highest
caliber were accepted for presentation and publication. Demonstrating a clear focus on scientific
excellence, this third Journal and the Science/Research Track at the conference, document
CSUN’s commitment to involve scientific researchers from all over the world to fulfill its
mission as a platform of exchange with full cooperation and support of all stakeholders.
We would like to thank the authors, the Science/Research Track review panel, the Center on
Disabilities team at CSUN, and the editorial staff for their professional support. As always, we
are grateful for and appreciate the many participants and partners who have contributed to the
Annual International Technology and Persons with Disabilities Conference throughout the first
30 years. As we begin to move into our 4th decade, we will continue to seek out this support and
collaboration and hope you will join us at our 2016 event where we will rebrand the conference
as the “CSUN Assistive Technology Conference”.
Welcome once again to our third publication of “The Journal on Technology and Persons with
Disabilities.” We hope you will continue to enjoy our endeavors and with your continued support
of the Center on Disabilities at CSUN and the annual conference we can all work together in our
mission of “changing the world for people with disabilities.”

Development of a Math-Learning App for Students with Visual Impairments 2
Introduction
Educators, researchers, and practitioners have noted that math learning is often especially
difficult for students with visual impairments (VI), and that this may contribute to their low
numbers in math-intensive college majors and professions (Freeland, Emerson, Curtis, and
Fogarty; Goertz, van Lierop, Houkes, and Nijhuis; McDonnall, Geison, and Cavenaugh). In
particular, algebra is a critical “gatekeeper” course. Students who do not pass algebra are not
likely to pursue science or engineering. Often, the problem is that students lack proficiency in
key algebra-readiness skills such as division, fractions, decimals, and unit conversion. To address
the need to help students with VI build their algebra-readiness skills, the present project was
designed to adapt an existing online tutoring program for use in authentic educational settings by
students with VI, and their teachers of students with visual impairments (TVIs).
Discussion
The AnimalWatch program
The original online tutoring program (“AnimalWatch”) was developed with support from
the U.S. Department of Education (Beal, Arroyo, Cohen, and Woolf). The program emphasizes
word problem solving, which is generally considered a key component of mathematics
proficiency (Koedinger and Nathan). An efficacy study involving a randomized control trial
(RCT) design indicated that classroom use of the AnimalWatch software in California middle
schools was associated with improved scores on the state end-of-year math achievement test
(Schneider, Beal, Hauk, D’Silva, Li, and Allen). However, the web-based program was not fully
accessible for students with visual impairments. Thus, the project goal was to make the
AnimalWatch program accessible.

Selection of iPads as the delivery platform
The initial project challenge was to identify the best platform to meet the needs of students
with a range of visual abilities (low vision to educational blindness) and literacy media used to
access information (print, braille, audio) (Zhou, Parker, Smith, and Griffin-Shirley; Zimmerman,
Zebehazy, and Moon). The Project Team developed an online survey that was open in Spring
2012 to TVIs. Results indicated that TVIs (N = 88, from 27 states) believed that the iPad
platform, which includes Apple-proprietary accessibility features such as VoiceOver, an
integrated speech option, held the most potential for effective delivery of math instruction to their
students.
Features of the app
During the 2012-2013 school year, we developed a prototype iPad app (“AnimalWatch
Vi”) along with accompanying materials, and obtained feedback from students with VI and TVIs.
Math content. In its final form, the app includes 24 units covering math topics such as
fractions, decimals, unit conversion, solving one-variable equations, basic statistics, and basic
geometry. Each unit includes six word problems, each with two hints that are available to the
student after he or she enters an incorrect answer, and a short video showing the problem solution
that becomes available if the student cannot solve the problem. Two problems in each unit
include graphical information such as maps, tables, bar graphs, and diagrams. Students with VI
often lack opportunities to work with graphical information, yet this type of information is often
emphasized on math achievement tests.
Accessibility features
All text on the screen can be accessed in audio form either via VoiceOver or by a two-
finger single tap, which activates the app's internal speech that sounds like VoiceOver to the user.
