Planning and selecting appropriate interventions and strategies
Deaf-blindness means concomitant hearing and visual impairments, the combination of which causes such severe communication and other developmental and educational needs that they cannot be accommodated in special education programs solely for children with deafness or children with blindness.
34 CFR § 300.8(c) (2)
A student with deafblindness is one who
(A) meets the eligibility criteria for auditory impairment specified in subsection (c)(3) of this section and visual impairment specified in subsection (c)(12) of this section;
(B) meets the eligibility criteria for a student with visual impairment and has a suspected hearing loss that cannot be demonstrated conclusively, but a speech/language pathologist indicates there is no speech at an age when speech would normally be expected;
Texas Administrative Code
(§89.1040) (2) Deafblindness
(C) has documented hearing and visual losses that, if considered individually, may not meet the requirements for auditory impairment or visual impairment, but the combination of such losses adversely affects the student’s educational performance; or
(D) has a documented medical diagnosis of a progressive medical condition that will result in concomitant hearing and visual losses that, without special education intervention, will adversely affect the student’s educational performance.
Texas Administrative Code
(§89.1040) (2) Deafblindness
Does the child have enough vision to compensate for his lack of hearing?
Does the child have enough hearing to compensate for his lack of vision?
If the answer is “no” to both questions, then the child is deaf blind.

Visual Acuity
◦ sharpness of vision; the visual ability to resolve fine detail (usually measured by a Snellen chart)
Legally Blind
◦ Having 20/200 vision with best correction or a visual field of 20 degrees or less.
Visual Field
◦ The ability to see objects in the periphery of ones vision when looking straight ahead.
Light Perception
HM Hand Motion
CF Count Fingers
Partially sighted indicates some type of visual problem, with a need of person to receive special education in some cases
Low vision generally refers to a severe visual impairment, not necessarily limited to distance vision. Low vision applies to all individuals with sight who are unable to read the newspaper at a normal viewing distance, even with the aid of eyeglasses or contact lenses. They use a combination of vision and other senses to learn, although they may require adaptations in lighting or the size of print, and, sometimes, Braille
Legally blind indicates that a person has less than 20/200 vision in the better eye after best correction (contact lenses or glasses), or a field of vision of less than 20 degrees in the better eye
Totally blind students learn via Braille or other non-visual media.

Distorted perception of the world because of lack of non-distorted information from the distance senses (vision and hearing)
Difficulty in communicating or an inability to communicate with people and things in the environment in a meaningful way
Extreme difficulty in establishing and maintaining interpersonal relationships with others
Tactile defensiveness

Self-stimulation behaviors and discipline problems which may result from sensory deprivation, frustration, confusion and fear
Severe medical problems and/or other handicapping conditions which may lead to serious developmental delays
Delays in motor development
Inconsistent use of whatever vision and hearing is present. Sensory integration must be learned
John McInnes, A Guide to
Identifying and Programming for the Deafblind Infant and Toddler
The child cannot benefit from secondary or tertiary learning. He or she must be taught everything first hand.
◦ For typical children, 8% of learning is first hand,
12% is secondary, and 80% is tertiary
John McInnes, A Guide to
Identifying and Programming for the Deafblind Infant and Toddler
The child may not benefit from group instruction, because he or she cannot benefit from watching and learning others.
The child is deprived of many of the most basic extrinsic motivations, such as curiosity.
Sensory information is so distorted that it is ineffective as a source of motivation to explore and to interact with people and the environment
The child will not benefit from being left alone for long periods of time with toys.
John McInnes, A Guide to
Identifying and Programming for the Deafblind Infant and Toddler
Building a trusting relationship is the springboard in the education of students who are deafblind (van Dijk, 2001, p. 1). Because of the reliance of a student who is deafblind on others, to safely and meaningfully access the world that surrounds him or her, trust is at the core of all interactions and teaching.
A student must ask of an educator:
◦ “Can I trust you to help me access my world in a way that is clear and complete?”
◦ “Can I trust you to help me move safely between environments?”
◦ “Can I trust you to understand my needs and desires and to respond to me?”
◦ “Can I trust you to teach me the concepts that the other kids know?”
Communication is a primary component of concept development
Both skills and concepts must be taught
Skill
◦ Ability to physically complete a task
◦ A learned power of doing something competently
◦ A developed aptitude or ability
Concept
◦ Something conceived in the mind, a thought or notion
◦ An abstract or generic idea generalized from particular experiences
◦ A mental representation, image, or idea of concrete objects as well as of intangible ideas, such as feelings
“Understanding Deafblindness: Issues, Perspectives, and Strategies,” Alsop, L. Ed, 2002
Concrete concepts
◦ Relate to an object or something tangible
Semi-concrete concepts
◦ Relate to actions, colors, positions, or something that can be demonstrated but not held in one’s hands
Abstract concepts
◦ Relate to concepts which can be defined or described, but which are often left up to the perception of the individual
“Understanding Deafblindness: Issues, Perspectives, and Strategies,” Alsop, L. Ed, 2002
that objects exist that objects have permanence that objects differ from one another to label or name objects to identify the characteristics of the object the function of an object
“Understanding Deafblindness: Issues, Perspectives, and Strategies,” Alsop, L. Ed, 2002
Use activities which are meaningful to the child
Use activities that the child enjoys
Attach language to all efforts to teach skills
Build on language that is known to the child
Use of a total communication approach
Remove variables
Generalize the concepts to a variety of situations
“Understanding Deafblindness: Issues, Perspectives, and Strategies,” Alsop, L. Ed, 2002
Need one-on-one interaction from someone who can intervene or intercede between the child and the environment in such a way as to minimize the effects of multi-sensory deprivation and enable the child to develop maximum control over his or her life at a level appropriate to his or her age
John McInnes, A Guide to
Identifying and Programming for the Deafblind Infant and Toddler
Interaction and learning which is conducted within the framework of natural routines
Constant one-on-one interaction which provides consistent non-distorted information
Communication which will let the child know what is going to happen before it happens, what is happening while it happens, and what has happened after it has happened
John McInnes, A Guide to

Van Dijk’s Resonance Technique
◦ The teacher joins the child in movement
◦ The teacher stops the action when her presence is sensed
◦ The child verbally or physically expresses desire to continue
◦ The teacher accepts the cue and resumes the action
Resonance activities encourage the learner to shift selfstimulatory behaviors to behaviors that involve other persons and objects.
The teacher follows (joins in) the learners behavior and begins to lay the foundation for turn-taking interactions.
Rapport and trust are developing.
Coactive Movement Sequence
◦ An extension of resonance strategies
◦ The student demonstrates purposeful signals
◦ Sharing of common movement or action
Coactive Manipulation
◦ Hand-over-hand or hand-under-hand
◦ Should be systematically decrease
Representational Reference
◦ Prerequisite to the formation of symbols
◦ Mutually understanding a common item (Helen
Keller and “water”)
Distancing
◦ Ultimately leads to conceptual level of representation
◦ More symbolic in form
Provide opportunities to communicate
Create communication rich environments
Look at ALL of the student’s behavior as an attempt to communicate
C = communication
A = anticipation
L = learning
E = expanding content, form & use
N = iNteraction
D = dynamic partners
A = availability
R = representational levels
What do the calendar systems in your classrooms look like?

Project SALUTE (Successful Adaptations for
Learning to Use Touch Effectively) defines coactive signing as the physical guidance of the child’s hand(s) to facilitate production of a standard manual sign for expressive communication (Project SALUTE, 2002).
Coactive signing involves taking the child’s hands and, in a respectful way, molding the child’s hands through the signs, so that you are helping the child make the signs.
Project SALUTE defines tactile signing as a communication method based on a standard manual sign system in which the receiver’s hand(s) is placed lightly upon the hand(s) of the signer to perceive the signs (Project
SALUTE, 2002).
Tactile signing is used when the person places his or her hands under the child’s hands to express something to the child.

“Making the appropriate modifications and adaptations for a child with deafblindness is critical to their educational achievement. If his unique needs are not met, the child, no matter where he is placed, is in the most restrictive environment. He is cut off from any opportunity to learn. Unfortunately, these supports are not always easy or inexpensive to provide.” –Robbie

Touch is a proximal sense
Touch is impossible to eliminate
Touch provides information on one aspect of an object so multiple tactile images have to be synthesized
Vision is a distance sense
Vision can be eliminated
Vision provides immediate, holistic information
Creates a sense of belonging
Key to social relationships AND learning
Involves sharing a message between two people
◦ Receptive – understanding a message
◦ Expressive – creating and sharing a message
Use of Sensory Channels
◦ Most children will react with more than one sensory channel
◦ If a consistent pattern does not emerge, differentiate observed behaviors involving near and distant tasks.
Koenig and Holbrooke, 1993

“By conducting a thorough assessment of the child's visual functioning in accessing manual forms of communication, speechreading and cued speech, you can determine the supports that are necessary. This will help you and your team to develop the type of programming which has the most benefit for the child educationally and make that program accessible to him.” –
