How is your disability defined by the federal and state laws?

According to IDEA `04 the federal definition of mental retardation is significant subaverage general intellectual functioning, existing concurrently with deficits in adaptive behavior and manifested during the developmental period, which adversely affects a child's educational performance (Deutsch-Smith, 2007).
The American Association on Mental Retardation (AAMR) defines mental retardation as a disability characterized by significant limitations both in intellectual functioning and in adaptive behavior as expressed in conceptual, social, and practical adaptive skills. This originates before age 18. It categorizes each individual's level of functioning based on the level of support that person will require in order to function (Deutsch-Smith, 2007).
According to The Arc, Fragile X syndrome and Down syndrome are two conditions that are the most common reasons for mental retardation (Deutsch-Smith, 2007).
Fragile X syndrome (FXS) is a genetic condition caused by changes in the Fragile X Mental Retardation 1 gene (FMR1) located on the X chromosome that result in the cells not producing the Fragile X Mental Retardation Protein (FMRP). It is the most common cause of inherited mental retardation.
Down syndrome is a chromosomal disorder with identifiable physical characteristics, resulting in delays, in physical and intellectual development (Deutsch-Smith, 2007). It is caused by a chromosomal abnormality: for some unexplained reason, an accident in cell development results in 47 instead of the usual 46 chromosomes. This extra chromosome changes the orderly development of the body and brain (Health Newsflash, 2002). Down syndrome is the most common and readily identifiable chromosomal condition associated with mental retardation (Deutsch-Smith, 2007).
What are the developmental characteristics of persons with this disability?

Children who are cognitively impaired share similar developmental characteristics. The commonality amongst children with Fragile X syndrome and Down syndrome are as follows:
• stereotypic behaviors (hand flapping, and hand biting)
• short attention span
• intellectual disability
• deficient fine and gross motor skills
• hyperactivity
• hearing and language problems
• inability to relate to others in a normal manner

“The hallmark of the Fragile X syndrome is mental retardation… (Crawford 361)” Mental retardation, autism, and autistic type behaviors may be seen in varying degrees of children with Fragile X Syndrome. These children have speech problems, conversational difficulty, poor eye contact, and exhibit anxiety while in social situations.

Some children with Down syndrome have
• congenital heart problems
• high risk of developing leukemia
• obesity issues
• Short, high-pitched cries in infancy.

The physical characteristics that are shared amongst children who have Fragile X syndrome and Down syndrome are as follows:
• Poor muscle tone
• Hyperflexibility (excessive ability to extend the joints)
Physical characteristics of children and adults that have Fragile X syndrome are:
• long face
• large ears
• protruding jaw which may be subtle and influenced by age and race
• Strabismus
• flat feet
• large testicles.

Physical characteristics of children and adults that have Down syndrome are:
• Slanting eyes with folds of skin at the inner corners (called epicanthal folds)
• Short, broad hands with a single crease across the palm on one or both hands
• Broad feet with short toes
• Flat bridge of the nose
• Short, low-set ears
• Short neck
• Small head
• Small oral cavity.




If you were a teacher in a general education classroom, what information and strategies would help you best support a child with this disability? This would include academic and social support.

As a teacher in a general education classroom information useful to support the student would include:

• Knowledge of current research and validated teaching practices for Mental Retardation, Down syndrome, Fragile X syndrome, and any coexisting conditions, such as Autism.

• Written history and thorough assessment of the student’s cognitive ability, adaptive behavior, need for supports and interests to plan an individualized teaching approach with adjustments.

Teaching strategy based on normalization and dignity of risk includes:

• A hazard free environment
• Model appropriate classroom behavior
• Involve students in writing classroom expectations
• Reinforce courtesy, respect, and self advocacy
• Visual reminders and labels
• Emphasize hands on approach
• Sit student in section of room with minimal distractions
• Model the entire lesson before task analysis
• Think/Pair/Share strategy
• Concrete concepts rather than abstract ideas
• Explain generalization of information
• Link content to daily life and practical use
• Teach small clusters of information
• Repeat using different materials and settings
• Reinforcement with progressive time delay
• Use audiotape, talking calculator, whole equation calculator, word predictive software and other technological assistance
• Physical activities and games for all to participate and feel successful
• Frequent, written feedback
• Assess progress and make modifications with the IEP team.


What resources would help you as a teacher to serve this child? (Websites, agencies, people within your school, curriculum materials: 2 or 3 line description for each resource is required.

The following resources provide useful information for the teacher to serve this student
