Pedagogy for teaching and learning Braille Devices


Introduction
In earlier days at the school for the blind in Paris, during 1819, the blind students learned through tangible writing system using dots, which was invented in 1819 by Capt. Charles Barbier, a French army officer. Then, Braille was first developed about 1820 by a young Frenchman named Louis Braille.
It took more than a century to accept Braille as an excellent way for the visually impaired to read and write. Even today many people underestimate the usefulness of Braille. Though, the CDs and other recorded synthesized speech materials are enjoyable, But, Braille is vital for note taking and helpful for educating math, spelling, and foreign languages.
The skilled Braille readers can read Braille as like print readers ie. 200 to 400 words per minute. But the only limitation of the Braille is there is no availability of enough Braille materials.
The teacher of visually impaired needs to understand the importance of  Braille writers which will help the students to learn reading and writing in Braille. Knowing this, teachers face many questions: At what age does Braille reading and writing can begin? What are all the prerequisites need to learn effectively?  How can I, as the teacher of visually impaired, help the students to develop speedy reading and writing in Braille? etc.   The following session will give us an answer to these questions.
Braille Writer
Main aims and Objectives of  teaching Braille to the visually Impaired Children were given below:
The student will understand,
a.       Identify the  parts of the Braille machine
b.      identify dot positions on  Braille machine
c.       to get oriented in reading and writing
d.      to insert paper into Braille machine
e.       help to punch the  Braille letters in Braille machine
f.       assist to help  to skip spaces(s) on Braille machine
g.      Assist to write  Braille words/phrases/sentences on the Braille machine to the first four lines
h.      Helped to reread what was written and make corrections
i.        Practicing to use Braille machine to take notes in the classroom.

Pedagogy in learning Braille:
  • Tactual Discrimination--The ability to discriminate discrete tactual differences is essential to become efficient in braille reading. Don’t try to teach the dot numbers. Help them to learn the configuration for the letter it will improve the reading speed.
  • Finger Dexterity--The effective braille reader will have "curious" fingers that move quickly, with ease. Many readers use all four fingers of each hand. This speeds up the reading process by allowing the reader a view of a series of symbols rather than a single cell.
  • Hand and Finger Movement—Teach to use both hands forefingers to read Braille is a good method. Teach the student to begin reading a line of braille by placing both hands at the beginning of a line. At the middle of the line, the right hand continues to read till the end of the line, whereas the left hand moves to the opposite direction to locate the beginning of the next line. The right hand finishes reading the first line, the left hand then reads the first words on the next line, and the right hand quickly joins the left hand on the second line.
  • Light Finger Touch—at the beginning students may have a heavy touch; but, to be good two hand readers one must learn a light touch. It can be learn through various prerequisite activities ie. Paste a thread in a straight line and ask the child to slide their fingers across the thread without moving paper. And the similar activities will improve the child’s   practice and attention to the task. As well as the child will learn to move his hands smoothly from left to right without stopping.
  • Page Turning--The student should be instructed to turn the page quickly with the right hand when the left hand cannot find another line.

Make It Fun

1.      Emphasize enjoying braille and having fun with it.  There is an expression that “play is the work of children.” It’s important for young children with visual impairments to enjoy reading and writing braille, rather than regarding it as an arduous task that is to be resisted.  Adults can make braille fun by incorporating children’s ideas in what they read and write, in keeping sessions short, and in modeling their own pleasure in braille literacy
2.      Give children the opportunity to playfully explore reading and writing.  Let them pretend to read as they move their fingers across pages, even if they have no idea what the letters and words say.  And let them form patterns and pretend to write before you ask them to produce conventional braille characters.  This might involve children simply pressing any keys until they reach the end of a line and the bell rings, or creating an up-hill-down-hill pattern by pressing dots 3 then 2 then 1 then 4 then 5 then 6, or making a simple tactile-graphic by alternating dots 1-2-4-5 with dots 2-3-5-6
3.      At the beginning of the curriculum, enthusiastically accept approximations, or all attempts to read and produce braille.  Then gradually guide children to use correct posture and hand formation, to read real letters, to decode real words, and to produce Braille which is increasingly closer to conventional braille.  A component of incorporating fun into early braille is giving children the freedom to attempt it without needing to adhere to rules they are not  developmentally ready for.  That is, while some children will be motivated to form correct characters with correct fingering right from the beginning, others will be easily discouraged if every early attempt is suppressed because a key is pressed with the wrong finger, or a character is inverted.  As long as correct posture and fingering are expected in a reasonable amount of time, inefficient posture and movement habits don’t seem to persist.  Given this, a successful practice is to enthusiastically respond to all early attempts to read and write, even when they are incorrect, then gradually expect greater and greater accuracy.

Make It Meaningful

1.      Let children experience whole events, from obtaining books or a braillewriter and paper, using them, then putting them away. It clearly takes time for a child to walk to a shelf, pick up a piece of paper and a braillewriter, carry these to his/her desk, load the paper in the braillewriter, produce his/her work, unload the paper, and pass in the paper and store the braillewriter back on the shelf.  However, participating in the whole event allows the child to understand the literary process and develop independent literacy habits.  The child doesn't need to participate in the full process every time he or she writes.  However, it is important for him/her to do this periodically, or at least to participate in some of the obtaining/putting away steps regularly.
3.      Let children witness adults reading and writing braille  Fully sighted children regularly see adults as they read books, signs, menus, instructions, etc., and they see them as they write notes, lists, letters, etc.  In witnessing adults doing literacy, sighted children learn about literacy tools, literacy techniques, and purposes for literacy.  With these models, they become motivated to do literacy, themselves.   Future braille users need these same models.  To accomplish this, even if adults read braille visually and not by touch, they might open their own  braille books as they are sitting beside children, explicitly labeling what they are doing.
4.      Integrate reading and writing, so that children continuously read back what they have written.  Braille reading and braille writing are quite separate processes. First, they are based upon different sensory systems.  Braille reading is tactile and motoric; dots are felt through the touch receptors in the fingertips as they move across lines.  Braille writing is kinesthetic/proprioceptive and motoric; dots are formed by moving the fingers to press specific keys, and braille writing is mastered by memorizing how the joints in the fingers feel as specific keys are pressed. 
5.      Approach the mechanics of braille production and reading within the larger context of Braille literacy.  Give children opportunities to produce braille characters which are meaningful and functional for them as soon as possible.  Children are often motivated to read and write their own names, and those of friends and family members. 
6.       

Make It Developmental
1.      Allow some portions of lessons to be child-led, that is, let the children have some choices as to what they write with the braillewriter.  This can provide more functionality and more motivation in braille literacy curricula. 
2.      In sequencing both producing and reading braille characters, build from symmetrical to asymmetrical, from fewer dots to more dots, and from unique characters that are easily reversed and/or inverted
3.      Begin by scheduling short lessons, and expect speed and stamina only at the end of the curriculumYoung children have short attention spans, perhaps especially for the more structured, seated tasks of braille literacy.   Physically, it takes time to learn to maintain correct reading and writing posture and hand/finger positioning, to tolerate the sensation of running their fingers over Braille lines, and to strengthen each finger, especially for pressing the keys for dots three and six.   It also takes time for children to build up speed in reading writing, especially with the letters with more dots
Conclusion
Without a doubt, technology has become an integral part of our daily lives, especially for people with disabilities. New devices make it possible for those of us with physical, visual and other impairments to do things that were previously impossible. Braille will always be an important means of reading and writing for people without sight. Although audio books and screen-reading technology help us have instant access to print materials, nothing can substitute the confidence and independence that reading and writing Braille provides. Both Braille and technology are equally important for people who are blind, and this will always be true no matter the time period we live in.
