• Some people can better absorb information via a particular medium – Some Students may remember color patterns
while others may remember musical patterns better.

“The whole is greater than the sum of its parts"

• Using several media together is even better!
• Using multiple media concurrently has the potential for an even higher overall transfer/absorption rate.
