Teach to learn

Requiring students to share what they have learned helps them more fully understand and retain the new knowledge.

Dr. Gary Phillips of the National School Improvement Project makes this claim:

People retain learned material at the following levels:

  • 10% of what we hear
  • 15% of what we see
  • 30% of what we see and hear
  • 80% of what we experience actively
  • 90% of what we teach others
