Background In the first half of the 20th century
children learned to read using alphabetic or uncontracted braille, also called Grade 1 braille.
They then learned Grade 1½ (a few contractions). Finally they learned contracted or Grade 2 braille (all contractions).
Background The American Printing House for
the Blind and other producers of braille began to produce books only in contracted braille the 1930’s.
Teachers began to teach contracted braille to children who were learning to read.
Some teachers now wonder whether early use of uncontracted braille
might promote better reading skills.
Most students are in public schools classrooms, and a professional who knows contractions is not always available.
Early reading speed might be increased by practice with fewer symbols.
Other students and the classroom teacher can use uncontracted braille.
The ABC Braille Study Five-year longitudinal – 2002
through 2007 Quantitative and qualitative
research Children in special schools and local
schools Teachers and parents choose
contracted or uncontracted braille for initial reading instruction
Children Enrolled Criteria
Totally blind or with light perception only At least 4 years of age Attending pre-k or kindergarten Potential to be a braille reader English is primary language for
instruction All adults and child give consent
Children Enrolled
44 students are enrolled or in process.
Approximately equal groups of students began in contracted and uncontracted braille.
Children Enrolled
Placements 7 are in special schools. 37 are in public schools and agencies.
Locations 12 U.S. states, 1 Canadian province. 39 U.S. children, 5 Canadian children (4
locations in 1 province).
Project support
Primary Funding is from the American Printing House for the Blind.
Additional funding has been provided by American Foundation for the Blind Canadian Braille Literacy Foundation Special Educational Technology, British Columbia
Quantitative Currently 216 variables being
recorded, with possible additional variables.
21 students from 2002 continued through this year, beginning the longitudinal investigation.
40 students in Year 2 have been continued through Years 3-5.
Research Questions
1. Are there differences in reading rates and comprehension, vocabulary, fluency, word recognition, and reading achievement levels of children who are initially taught contracted braille as compared to those who are taught uncontracted braille? (Quantitative)
Research Questions (continued)
2. Are there differences in writing, vocabulary, and spelling abilities of children who are initially taught contracted braille as compared to those who are initially taught uncontracted braille? (Quantitative)
Quantitative Measures Texas Primary Reading Inventory Johns Basic Reading Inventory Extended oral reading sample Writing sample (discussed later) Brigance Reading Vocabulary
Comprehension Subtest Brigance Spelling Subtest
Data Analysis
Big picture is viewed with descriptive statistics
Details through log-linear analysis, hierarchical linear modeling, multiple linear regression
Longitudinal structure with analyses of covariance and effects with trend analysis
Large scale differences (i.e., group) will be checked with t-tests and chi squares
Research Questions (continued)
3. Are there differences in attitudes towards reading and writing in children who are initially taught contracted braille as compared to those who are initially taught uncontracted braille?
Research Questions
4. Are there differences in the quantity and quality of literacy and interactive experiences in general education classrooms, the home environment, and in the community of children who are initially taught contracted braille as compared to those who are initially taught uncontracted braille?
Qualitative Data Observations of classroom
Coded for literacy activity, peer involvement, availability of braille, professional in charge
Interviews with professionals, family, student Identify environmental differences that
might affect literacy acquisition
Literacy Experiences Demographic information form Curriculum materials checklist Braille instructional materials form Family survey of reading and
writing Observations – time diaries Interviews
Observations Time sampling of events in
educational environments for contracted and uncontracted groups With general education teacher with paraprofessional In classroom activities with peers Braille instruction with TVI Braille instruction with paraprofessional
Interviews
Initial family interview when child enters study
Family Survey of Reading and Writing Experiences
Annual interviews with TVI Classroom teacher Paraprofessionals Participating students
Literacy Experiences Family Survey of Reading and
Writing Experiences If adults and children in the home know
braille If other read to child with braille and/or
prinbooks If child has brailled children’s books at
home Common items used at home that are
in braille
Methods Direct assessments of reading and
writing skills conducted each spring Assessments administered in
uncontracted or contracted braille, depending on group
Compilation and data analysis organized and performed by Rob Wall (Western Michigan University)
Protocol for reading sample
Videotaping children while reading for five minutes - analyzing only the last four minutes
Reading passages with which child is familiar - has read at least once previously
Videotaping shows child’s hands and reading material
Analysis of hand movements and inefficient characteristics
Question for teachers about teaching HM
Types of Hand Movements
One-handed reading left hand - right hand
Two handed reading left used as marker left and right together left and right together until near end of
line, and then separate both hands used independently -
scissors fashion
Inefficient Characteristics Scrubbing Single Regressions Multiple Regressions Pauses Searching Motions Erratic Movements
Writing AnalysisPrompt: “Write a story about…
Kindergarten: your favorite thing to do at home”
First grade: your favorite thing to do at recess”
Second grade: your favorite thing to do with your friends”
Third grade: your favorite thing to do on the weekend”
Assessment of written passages Lines of braille in passage Sentences in written passage Sentences in passage read aloud
(on videotape) Words in passage % of recognizable words in passages Likert scale ratings of topic relevance,
spelling, punctuation, coherence
#2: I like to roll my ball on the bench. I like to bounce my ball on the bench.
#4 Sometimes I like to play bus at recess. I like to perform for my friends. I sometimes like to just walk around. I also like to go down the slide. Do you like to go down the slide?
Future Plans Continue data collection through
the 2006-2007 academic year Prepare proposals to continue the
longitudinal study, address new questions that arise, e.g., children with dual reading media
