Principle of Inclusivity
… means providing all groups of students, irrespective of
educational setting, with access to a wide and empowering
range of knowledge, skills and values … recognising and
accommodating the different starting points, learning rates
and previous experiences … valuing and including the
understandings and knowledge of all groups … providing
opportunities for students to evaluate how concepts and
constructions such as culture, disability, race, class and gender
are shaped.

Types of Deafness
•
•
•
Conductive Hearing Loss - an impairment to the physical
mechanism of the outer and/or middle ear; occurs as a
result of trauma or Otitis Media (OM); OM is caused by
colds, flu, large adenoids or tonsils, and allergies
Sensorineural Loss – results from damage to the auditory
nerve or the workings of the inner ear
Mixed Loss – combination of conductive and sensorineural
loss
NB: Hearing impairment is not just a simple reduction in auditory
sensitivity. Perceived sounds may be distorted.
Incidence of Conductive Hearing Loss
•
Specific populations show greater susceptibility –
Aboriginal children, Inuits (Eskimos), Apache and Navajo
Indians, children with particular disabilities; some evidence
of higher prevalence in SE Asian and Hispanic children
(Hasenstab, 1987). Maori children (NZHTA, 1998).
•
75% to 80% of Aboriginal children on any one day
•
20% to 25% of European children on any one day
What to do if you suspect a hearing loss
Refer the child for assessment, which will determine:
1. If the child has a hearing loss
2. What the degree and nature of the loss is
3. How the hearing loss can be medically managed
effectively
Assessments that are conducted:
Audiometry (1 of 3)
•
Air conduction screening
- sound goes through middle ear
•
Masked or unmasked tests
•
Bone conduction screening
- sound bypasses middle ear
•
Specialised tests for young children, e.g. Distraction Test
for babies conducted by Infant Health Nurses

• May have delayed speech development
• May miss up to 50% class discussion if
speaker not visible
• May need hearing aid
• Will need special education attention
Severe (60 – 89 dB)
•
•
•
•
•
•
•
May understand speech at <15cm
Hears loud environmental sounds
Will have delayed speech/language
Will need hearing aid
Requires auditory training
Uses vision for additional cues
Speech/language will not develop
spontaneously if loss present before
1 year old
Moderate (45 – 59 dB)
•
•
•
•
•
•
Understand conversation at 0.5m
Will have difficulty at school
Likely to have language delay
Will have poor speech clarity
Will need hearing aid
Will need special education
assistance and probably special
training for listening
Profound (> 90 dB)
• May only be aware of very loud sounds
• Speech and language will be defective
• Visual and gestured cues essential for
learning
• Needs full time special education
assistance
• Use of a hearing aid
Assessments that are conducted:
Tympanometry (2 of 3)
•
Assesses status and function of
middle ear
Looking for the following:
•
Is the eardrum intact?
•
Is the middle ear system mobile/immobile/partly mobile?
Assessments that are conducted:
Otoscopy (3 of 3)
•
Examines the appearance and texture of the eardrum
•
Screening otoscopy checks for blocked ear canal, state of
eardrum and presence of fluid in middle ear
•
Diagnostic otoscopy differentiates between the different
types of Otitis Media
Normal Eardrum
•
Thin and semi-transparent
•
Pearly-grey appearance
•
•
Often some structures within
the middle ear can be seen
A “cone of light” extends
downwards and forwards
from the umbo (where the
eardrum attaches to the
malleus or hammer)
Types of Otitis Media
1. Acute Otitis Media - An acute infection
of the middle ear and eardrum. Starts
suddenly, may be caused by bacteria,
viruses or a combination. Children may
have ear pain, fever, rub or pull their
ears, may be irritable, cry, lose their
appetite, vomit or have diarrhoea.
Eardrum can be bulging and may/may
not be red, and may not move as it
should.
Some children, however, may not
show signs of this infection!
Types of Otitis Media
2. Otitis Media with effusion, ‘Glue ear’ – Fluid in
the middle ear, the consistency of egg white.
Distortion of the eardrum, prominent blood
vessels and bulging in upper half, dullness in
lower half. Outline of malleus (hammer) is
obscured. Fluid levels can be seen behind the
drum.
Some children may complain of ear pain, but
don’t have the signs and symptoms of Acute
Otitis Media.
Types of Otitis Media
3. Chronic Supparative Otitis Media, ‘Runny ear’
– Serious and persistent infection. Hole in
eardrum and pus flows from middle ear into
canal. Usually follows untreated or poorly
treated acute middle ear infection. Often occurs
in children under 5 and in children who live in
poverty and poor environmental conditions. Ear
pain not common. Without treatment damage
to middle ear bones will occur and increasing
hearing loss. May also cause serious infections
in mastoid bone and in brain.
Impact of Otitis Media is Multi-Factorial
•
Age at which the child experienced the first incidence of
OM
•
Number of incidences under the age of 12 months
•
Access to good medical intervention
•
Access to certain types of interactions within the family
•
Access to audiology and speech pathology
•
Child’s general health
Activity:
So what’s it like to have CHL?
Morning Tea
Medical Treatment
•
Glue ear and infections often clear up without treatment
•
Antibiotics will help with an infection but will not clear up
the fluid build up that occurs with glue ear
•
Runny ear does not clear up quickly or easily. The
recommended treatment is twice daily syringing with
Betadine, followed by dry mopping, then drops, for 16
weeks.
Surgical Treatment
Grommets are recommended
for children who have had
more than 6 infections in a
year or one bout of Otitis
Media lasting more than 3
months
More Surgical Treatment …
•
Myringoplasty / Tympanoplasty – patches the eardrum;
not suitable for runny ears
•
Mastoidectomy – removal of part of mastoid bone and
other parts of middle ear because of erosion by fluid over
long period of time
•
Middle ear reconstruction
Amplification Options
Behind-the-ear style sits behind ear,
amplified sound travels down a tube into
customised earmold
In-the-ear hearing aids fit inside ear
In-the-canal hearing aids are smaller and
fit the size and shape of ear canal
Completely-in-the-canal hearing aid is
worn deep inside canal and are almost
invisible.
Other Amplification Options
•
Hearing hats/head bands – bone conduction
•
Personal FM systems

Speech and Language
•
•
Speech – the sounds of a language; the ability to pronounce
and distinguish different sounds; and the ability to
coordinate the voice box, lips and tongue to produce sounds
Language – the spoken, written or other symbol system
used to convey (expressive) or understand (receptive)
meaning
Activity:
Communicating without speaking
Oral Language is fundamental …
Speaking and listening provide the foundation for all
language learning and underpin the successful development
of reading and writing skills.
Proficiency in speaking and listening contributes to
children’s abilities to learn effectively in all learning areas.
First Steps: Oral Language Developmental Continuum
Cultural Considerations
•
Language is the repository of the speakers’ cultural knowledge
and reflects their world view. When we devalue a language we
devalue everything contained within and reflected by it.
•
The Western school system is set up to reflect a literate
tradition. It assumes all children come to school knowing how
to work with language in a de-contextualised manner. We
need to be aware that children may come to school with rich
language experiences from predominately oral traditions and
cultures.
Impact of CHL on Speech
and Language Development
•
Hearing children learn the basics of language passively, by hearing it. This
avenue is not open to children with hearing losses.
•
Creates a barrier for normal speech development and phonological
processing
•
Causes delays in the development of a child’s first language and any
additional language, particularly when the hearing loss begins at a very
young age:
Poor vocabulary and semantic organisation
Expressive and receptive language difficulties – language structure, word
endings, grammar, word order etc.
•
For Aboriginal children, diminished auditory experiences can affect
opportunities for learning about culture, law, relationships, etc. (Clarke,
1992)
Impact of CHL on Comprehension
‘Oral comprehension’ relates to the ability to understand the meaning of
what is spoken. Comprehension is dependent upon context, previous
knowledge and experience, sentence length, concepts and attention.
(adapted from Health Department of WA Teacher Modules, 2000)
A child with CHL or a history of CHL probably has:
•
•
Difficulty with lengthy or complex instructions
An underdeveloped vocabulary including concepts and
descriptive terms (e.g. in Preprimary will not understand concepts
such as location [over/under…] or size, and descriptive terms [colour,
shape])
•
Difficulty with some questions (e.g. in Preprimary can’t
understand ‘wh’ questions [who, what, when, where])
Impact of CHL on Semantics
Semantics refers to the link between our thoughts and ideas and the
vocabulary and concepts we use to express these thoughts. Semantic
organisation describes how we organise incoming information in order to
make sense of and later retrieve it.
(adapted from Health Department of WA Teacher Modules, 2000 ; Holt & Spitz, 2000)
In Preprimary, a child with CHL or a history of CHL probably:
•
Has a vocabulary of less than 1500 words
•
Speaks in sentences of < 3 to 5 words
•
Doesn’t use language socially
•
Is slow to learn words and concepts (due to ‘fuzzy’
representations)
Impact of CHL on Semantics
Other indicators may be :
•
Difficulty integrating new information with existing
•
Limited conceptual understanding
•
Under-developed receptive and expressive vocabulary
•
Difficulty retrieving words
•
Difficulty generating ideas related to a topic
•
Conversational difficulties
Impact of CHL on Syntax
Syntax or grammar refers to the way we organise words into sentences.
Grammatical rules tell us which words should come before or after others,
the word endings we should use and the way words combine to form
sentences.
(adapted from Health Department of WA Teacher Modules, 2000 ; Holt & Spitz, 2000 ; Owens 1992)
•
Problems with forming linguistic categories such as plurals
and tenses
•
Grammatical errors and unusual word order
•
Incomplete sentences
•
Restricted use of describing words (adjectives/adverbs) and
connectors (but, then, because, so …)
Impact of CHL on Narrative
(Oral Texts) Skills
Narratives/Oral texts encompass such genres as stories, reports,
procedures, explanations, recounts and news telling. The common feature
of these genres is the linguistic structures that are used to tell and retell a
series of events in time order.
(Adapted from Health Department of Western Australia Teacher Modules, 2000 ; Holt & Spitz, 2000)
The Western-style narrative structure tends to be linear in
nature and uses a distinct model that may be difficult to
understand for Aboriginal and other CALD students. If a child
has hearing problems they are likely to have additional
problems with story grammar and descriptive vocabulary.
Impact of CHL on Phonological Processing
Phonological processing relates to the ability to use the sounds of a language to
process oral and written language, which allows us to form phonological codes
and access a word stored in our brain’s lexicon. Phonological awareness skills
(explicit awareness of sound structure and ability to manipulate structure of
words) are dependent on phonological processing skills.
•
Need to hear words to learn words – to ‘map’ words to objects
car? ar? bar? tar? …
•
Absence of second sound in two-letter blend (eg frog, block)
•
Absence of unstressed syllable(s) (banana, dinosaur, balloon)
•
Poor discrimination and identification of sounds
Impact of CHL on Phonological Processing
Australian English speech sounds with which ESL/ESD
speakers frequently are not familiar:
t, d, th
a, e, ir, ai
f, v, b, p, k, g
o, o-e, oo/u, u-e
s, z, sh, ch, j
u, i-e, oi, ai
ee, i, e, a
o, oar, ar, oi, ir
a, ar, u, ow
(Adapted from Making the Jump,
Catholic Education, Kimberley, 1997)
Consider the similarities between these sounds (voice, placement of lips
and tongue). If a child can’t hear a sound correctly he/she will have
considerable difficulty learning to say it correctly, particularly if he/she is
reliant on visual differentiation.
Impact of CHL on Metalinguistic Skills
Metalinguistics refers to the ability to use language to think, talk about, reflect
on and manipulate units of language.
•
Don’t know how to play with sounds and words, eg rhyming
•
Don’t know what a ‘word’ is so have difficulty understanding
word boundaries and segmenting sentences into words:
“Ontheweekend”, “smorning”
Impact of CHL on Metalinguistic Skills
•
Difficulty manipulating words within words (eg take ‘sun’
from sunshine); syllables in words (eg take ‘ing’ from doing);
sounds in words (eg boat has 3 sounds: b / oa / t; take ‘c’ from
coat); and blending sounds to make words (eg s – t – o – p)
•
Poor understanding that words are arbitrary symbols of a
language system – words usually don’t contain any hint of
their meaning
•
Problems working out how communication breaks down
Impact of CHL on Pragmatics
Pragmatics relates to the use and functions of language for communication.
Pragmatic awareness is the knowledge of conversational rules and includes
both verbal and non-verbal aspects.
(adapted from Holt & Spitz, 2000 ; Owens 1992)
Children with a hearing difficulties may have problems with:
•
Entering into a group, requesting, responding and taking
turns
•
Initiating conversations
•
Understanding subtle social rules
•
Accepting others points of view and others’ feelings
•
Monitoring the listener
Impact of Hearing Loss on Socialisation
Children with hearing difficulties, however, are also likely to
present with social and emotional challenges due to:
•
Their own frustration and/or the frustration of their peers
•
Avoidance
•
Just not “getting it” i.e. the subtleties and unwritten rules of
social exchanges
Activity:
Consider a child you know who has a
suspected/confirmed hearing loss.
What difficulties have you observed?
What are some strategies that have
been effective with this child?
Summary of Educational Impact of CHL
•
More than three infections under the age of 12 months is a significant risk factor
•
Even without a current ear infection children can still suffer the effects of a
history of conductive hearing loss
•
Poor ability to discriminate sounds in words and to hear words in words;
difficulty chunking words into individual parts; and relationship between own
sound repertoire and written alphabet is tenuous
•
Language learning difficult; frequently have restricted content, vocabulary,
language and confidence; prediction as a reading strategy is not functional
except with simple or familiar texts
•
Poor foundation for literacy and without help will fall further behind every year
•
Socialisation difficulties and behaviour problems are likely
•
The most debilitating aspects of deafness are secondary to the hearing
impairment itself
Lunch

•
•
•
•
•
•
Teamwork including the AIEO, district CIOs, audiologist/speech
pathologist/psychologist/occupational therapist….
Point of error analysis to understand the strength and weaknesses of a
child’s system.
Practice at the phonological level and oral level before moving into the
written code.
Research has shown that a drill orientation program works well with
young children while the meta approach is most effective with older
students.
Use practice, repetition, buddying, small group work, pre-teaching and
one-to-one tutoring as tools.
Investigate amplification.
