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
