Mike Dowling and Adam Bourret
What is Down Syndrome?
It is the most recognizable genetic
condition associated with intellectual
disabilities
 Is one of three chromosomal
abnormalities, the most common one is
called trisomy 21

Trisomy 21
Is the presence of an extra number 21
chromosome
 Resulting in 47 chromosomes instead of
46 (23 from each parent)
 Can be diagnosed prenatal

Facts
1 in 700 children are born with DS
 5,000 born in the US each year
 Fathers are genetically responsible for 25%
of all cases
 Women over the age of 35 present the
highest risk (1 in 290)

 age
40: 1 in 150 births
 At 45: the risk is 1 in 20 births
Characteristics

short stature
 poor muscle tone
 small nose with flat
bridge
 eyes slanted up ward
and outward
 exaggerated folds of
skin around eyes
 mild to moderate
obesity
 under developed
respiratory and cardio
vascular systems

short legs and arms in
relation to torso
 short neck
 small low-set ears
 small head and flat face
 broad hands and feet
 stubby fingers and toes
 poor balance
 perceptual difficulties
 poor vision and audition
Motor Performance
Delays or deficits
 Slowness of movement


Have a smaller overall brain volume
 Significant
reductions in both cerebrum
and cerebellum.
Down Syndrome
Risk Factors
 Age more rapidly
 Median Age at death:

 Caucasian:
50 years
 African American: 25 years
 Other Races: 11 years
Teaching Strategies

Most Individuals with DS do not
progress beyond the intellectual
capabilities of a 6-8 year old
 Don’t
assume child in incapable though
Rate of response may also be slower
 More repetition is necessary
 Short attention span
 Distractibility

Effective Strategies

Effective For Students With DS
 Routine
 Repetition
 Scaffolding
 Use
of peer partners
 Know individual student needs
 Reproductive teaching methods
 Attention
span
Task Analysis
Helpful in modifying a task for individual
needs
 Break tasks into smaller steps
 Analyze the sequence
 Train each step
 Ex: Breaking down the steps of how to
throw a ball and teaching them in
sequence

Pacing
Students with DS generally have a
slower rate of response
 Pacing involves both the rate of
speaking & moving
 Wait Time
 Use demonstrations and visuals
 Example: After asking a question wait a
minimum of 5 seconds for the response

Reinforcement
Simple yet effective
 Low task persistence
 More interested in people than objects
 Motivated by the praise and
encouragement of significant others

Adventure Education
Promotes positive social skills between
students with DS and peers
 Promotes high levels of enthusiasm &
participation
 *Modification Task*

Behavior Management
Plan
 Routine, rules & consequences
 Make learning exciting
 Positive reinforcement
 Should promote independence & self
management
