Issues Related to Inclusion: Sensory Impairments


Issues Related to Inclusion:  Sensory Impairments
Hearing:
Number of variables may place children who are hard of hearing at risk for educational failure, one being the environment.  The noise levels of the classrooms, gym, cafeteria and the computer rooms all have different levels.  A teacher generally speaks at the same level as background noise.  In all of these settings, children with any hearing loss are challenged.
For children who are completely deaf, the impact on communication is far more devastating.  Even with the most sophisticated hearing aids, speech can be inaudible to the child.  This means children face major difficulties in learning language, as well as significant articulation, voice quality, and tone discrimination problems.  Deaf children prefer solitary constructive play, whereas hearing children of the same age prefer co-operative dramatic play. 
For teachers, the most difficult challenge to deal with (especially in the severe form of total hearing loss) is the deprivation of language which creates a barrier to learning.  Many general classroom teachers are not very knowledgeable about hearing impairment and it is not unusual for teachers to express anxiety about working with a student with a hearing impairment in a general setting, especially if adequate communication and social supports are lacking.
Inclusion for students with severe hearing losses has not yet emerged.  It seems reasonable to argue that there should be various educational settings available.  In general, the educational setting for a specific child is determined by linguistic needs; the severity of the loss and the potential for using residual hearing with or without amplification; academic level; social, emotional, and cultural needs, including appropriate interaction and communication with peers; and communication needs; including the child and the family’s preferred mode of communication.
 
VISION:
Social/Emotional:
Children who are visually impaired miss many important non-verbal cues given by either or teachers and peers through facial expressions, gestures, and body language.  Since these children fail to make expected eye contact with peers and typically will not smile, communication with sighted people may be harmed by lack of eye contact.  The failure to look at people may be interpreted as disinterest rather than a s a manifestation of the disability itself.
Play Behaviour:
Children with severe visual impairments do not display a full range of play behaviours; the delays seem to be related to the limitations imposed by the visual impairments.  Children with severe losses may be substantially delayed in sensory motor play and delays in social play and can be at least 2 years behind sighted children.  They are rarely sought out by their peers, infrequently severe as role models and are the least preferred play partners of typical children.
Working with the Resource Teacher:
Many students who are blind or visually impaired spend the majority of their day in a regular class with peers.  While many of their learning opportunities need not take a great deal of adjustment, there are certainly specialized interventions and techniques that may be necessary.  Because the percentage of students with blindness and visual impairments within a given population can be very low, it is not always a reasonable expectation that all classroom teachers will have the specialized knowledge needed to be as effective as possible.  Because of this, it is not uncommon for boards of education to have what would be referred to as itinerant teachers or resource persons for the following types of things:
-       Explanation of the student’s impairment to educators at the school level
-       Assessment of the student’s residual vision
-       Provision, training (teacher and student), and integration of specialized equipment
-       Strategies of instruction
-       Provision of Braille
-       Socialization and adaptation strategies (student, teacher, and classmates)
-       Orientation and mobility information
-       Available resource support materials and organizations
In this video, they students are  performing "The Lion Sleeps Tonight" from the movie "The Lion King". The girls in the back sing, while the students in the front sign the song, in Kenyan Sign Language, not ASL. So a lot of the signs are different from what you would normally see here in Canada and the US, as you will notice with words such as "Lion" and "Tonight".
This video is not in a school setting, but I just had to show everyone how these students came together on a trip to enjoy a circus just the way we all would!!!

VISION: definition, prevalence, categories

 SENSORY IMPAIRMENTS
Sensory impairments consist of hearing and visual impairments
Visual Impairment 

Mild visual impairments with low vision, includes totally blind
Prevalence:
-in children, blindness is the least prevalent of all disabilities
-about 1/1000 children under 18 yrs. of age have severe vision impairment
-vision loss is primarily an adult disability
-only 10-15% of total population are totally blind

HEARING: definition, prevalence and etiology


SENSORY IMPAIRMENTS
Sensory impairments consist of hearing and visual impairments
Hearing Impairment: hearing disability that includes the deaf and hard of hearing

 







Impairments
Outer Ear
Middle Ear
Inner Ear
External otitis (swimmer’s ear)
Otitis media-mucosal lining of middle ear becomes inflamed and the cavity fills with fluid (most common ear infection in children)
Presbycusis- deafness of age is the most common cause of auditory defect
Auditory atresia (missing or undeveloped auditory canals)
Otosclerosis- hereditary condition, destruction of the capsular bone in middle ear and the growth of a web-like bone that attaches to and restricts the stapes

Microtia (mis-shapen or extremely small pinna)





 
Prevalence of Hearing Impairments
·      Inconsistent translations
·      Confusion regarding identification and reporting
·      Methodological problems in surveys and shortage of research in areas
·      Difficulties in accurate early identification of hearing loss
·      Increased of hearing impairment with age
·      Difficulties in estimating hearing impairments among individuals with multiple disabilities, who are often reported according to their primary disability
Etiology
Audiologists are involved in assessments for hearing, recommendations, and fittings.
Otolaryngologists are medical personnel who deal with the ear, nose, and throat that affect hearing and speech.

Intellectual Disability: developmental issues



  Developmental Issues of Intellectual Disability

Potential is not always reached. Negative experiences can influence how people perceive themselves and their ability to reach goals.
Learned Helplessness: Negative experiences can influence how people perceive themselves, their self-esteem and their ability to reach goals- “If at first you don’t succeed, quit!” syndrome
Momentum: The importance of establishing within the student a sense of commitment to take responsibility for their learning; avoid learned helplessness (Bennett, p. 162)
Motivation: directs behaviour toward a goal


Did you know?
An intellectual disability not only affects the child but the whole family too – stress, worry and depression.
7 – 18% of people with intellectual disability have AD/HD
14 – 16% have mental illnesses, e.g. schizophrenia
10% suffer from depression
Assessment
Rating scales, achievement inventories, personal checklists, and individual administered tests of intelligence can all be used to determine a child’s intellectual and developmental functioning. Medical information relevant to the student’s situation ideally should also be available. It is also most important to include reports by parents, teachers and EAs who know the children and their abilities best.
Teachers in the classroom should not wait for the results of formal assessment, but start trying different strategies, based on their own informal assessment of the child’s strengths and needs, to help the child during the assessment waiting period.
Privacy regulations must be followed, and student confidentiality maintained at all times.
One important factor to consider regarding the assessment of a student: Are the tests results used reliable and valid? Many tests used in Canada may bias against children from lower socio-economic or different cultural groups. This may be one of the reasons there seem to be more children than expected from these groups with ID.

Inclusion… or not – see previous blogs 
Important Considerations
·      Positive attitude: Teachers need to approach students with recognition and acceptance. Students with ID have likes and dislikes, strengths and weaknesses, like all children. Use evaluative and positive feedback.
·      Collaborative approach: It is crucial that both teachers and assistants provide an atmosphere of mutual respect and understanding.
·      Instructional scaffolding: to continually encourage remembering. Students will excel with repetition. It is important to offer ‘drill’ and ‘repetition’ of new material in a fun and motivating way (games, puzzles, fun activities). Information, once stored in their long term memory, can be accessed as effectively as any other child can.
·      Use of reciprocal teaching: written material and dialogue involving both teacher and student, will help to discover the meaning of a written passage. Ability to assess low reading levels and accommodate projects with appropriate reading supplies and projects for this ability.
·      Use of technology and a variety of software can be very useful to children with ID.
·      Each program will need to be individualized to each students needs and unique strengths
Normalization: People with ID should be seen for their similarities with their peers, not for their differences. They should be allowed to thrive in the larger society, consistent with their age and adaptive ability, as much as possible.
Inclusion: Design for Learning/Education for All (Ontario Ministry of Education, 2005) supports the principle of inclusion, i.e. keeping all students in the regular classroom as much as possible.
It is not possible to lump all special students into one learning environment classification. For some students, a modified school environment may produce better results. Students should be considered on an individual basis, if not, the consequences can be potential disastrous one way or the other.
There is no cap on learning! LITERALLY! It just takes longer.
