Historical Context



Debates about the better
methods of communication
(manual or oral) originated
in the 1880s between
Edward Gallaudet and
Alexander Graham Bell.
The battery-operated
hearing aid was developed
after World War II.
The behind-the-ear hearing
aid was developed after the
transistor was created in the
1950s.

A brief history




1500s: Pedro Ponce de
Leon, a Spanish monk, is
the first teacher of
students who are deaf.
1817: The first school for
the deaf in the U.S.
opens.
1864: Gallaudet University
is founded.
1993: Closed-caption
decoders become
required components of
all television sets sold in
the U.S.

Deafness and Hard of Hearing
Defined

People who are deaf:




Have profound hearing
loss.
Have little use of
hearing, even with a
hearing aid.
Can be divided into three
groups:
 Congenitally deaf.
 Prelingually deaf.
 Postlingually deaf.

People who are hard of
hearing:

Have hearing losses that
impair their
understanding of sounds
and communication.

The Process of Hearing




The outer ear catches sound waves.
The middle ear turns waves into vibrations.
The inner ear produces electrochemical
signals that are sent through nerve cells
along the auditory nerve.
The brain then perceives signals and makes
them meaningful.

Types of Hearing Loss

Conductive Hearing Loss


Sound waves cannot travel to the inner ear.
Sensorineural Hearing Loss

This type of loss is caused by damage to the inner
ear or auditory nerve.

Degree of Hearing Loss





Mild: 21−40 dB

Age of Onset

Prelingually deaf



People who become deaf before they learn to
speak and understand language
People born deaf or who lose hearing as infant
Postlingually deaf



People who experience hearing loss after learning
to speak and understand language
Often able to retain abilities to use speech and
communicate orally
Can often profit from cochlear implants

Characteristics



The only commonality of people who are deaf
or hearing impaired is that hearing is limited.
IDEA ‘04 stresses severity of hearing loss,
communication needs, and any co-existing
disabilities.
A distinction is made between Deaf and deaf.

Deaf (capital D)





Members of a part of a
community
Considered to be a
minority group by its
members, not disabled
Use ASL as the primary
language
Do not use oral language

deaf:


83% of deaf children are
born of hearing parents.
These people use oral
communication at times.

Prevalence



Hearing loss in children is the number-one
birth defect in the U.S. It affects 14% of all
students.
Statistics about special education students
with hearing loss are unreliable due to
different criteria between states.
Over half of all adults over the age of 70 have
hearing problems.

Overcoming Challenges: Hearing
Aids and Cochlear Implants

Hearing Aids


Amplify sounds
Two different types of hearing aids

Analog


Digital


Make all sounds louder—background and speech
Automatically adjust volume by amplifying sounds
only to the degree necessary
Cochlear Implants

Surgically implanted with four parts

Microphone, speech processor, transmitter,
electrode array

Assessment

Two qualities of sound are measured in the
assessment process:



Early Identification: Universal Newborn
Hearing Screening


Frequency
Intensity
95% percent of children are identified at birth due
to universal screening.
Pre-Referral: Hearing Screenings

Students with mild to moderate hearing loss are
often overlooked.

Identification:
Auditory Assessments

Most children’s hearing is assessed by the air
conduction audiometry method.


Bone conduction audiometry method



Earphones are placed over the ears and the child
raises hand when he or she hears the sound.
Uses a vibrator placed on the forehead to bypass
the outer and middle ear
Goes directly to the inner ear
State- and District-wide Assessments

Require some accommodations specified in IEP

Early Intervention






Early identification is crucial.
Newborn hearing is screened in 41 states.
Early intervention allows children to be fitted
with hearing aids early in life.
Intervention before six months results in
better reading achievement and speech
abilities.
Preschool programs facilitate timely language
development.
Early intervention helps families meet special
needs.

Teaching Students with
Hearing Loss

Access to the General Education Curriculum

Interpretation of LRE for the Deaf community is
different than for many advocates and parents of
students with intellectual disabilities.




Many believe that the general education
environment with an interpreter can be too
restrictive.
Deaf advocates believe that Deaf students should
learn Deaf culture.
Many advocate for residential schools.
Instructional Accommodations

Modification of delivery of instruction

Collaboration


Teachers and educational interpreters need to work as teams.
A close relationship is needed between the teacher and related service
providers.

Planning and organization

Setting up standard meeting times

Storage and working space designated for the interpreter

Classroom organization and management
 The interpreter and the student must see the teacher.
 Placement should not be distracting to other students.
 There should be no glare or visual obstruction
 Courtesy and Social Convention should be considered.
 Everyone talks to student and uses eye contact.
 The interpreter is not a tutor.

Families



The most important point is acceptance and
inclusion by families.
Social services need to respond quickly to
families for early intervention services soon
after an early diagnosis.
Families experience stress with the
adjustments they have to make, but develop
coping strategies fairly quickly.

to assist deaf people?
What advances
might the future hold?
