The Learning Pyramid

The Learning Pyramid says that learners retain approximately:

• 90% of what they learn when they teach someone else/use immediately.
• 75% of what they learn when they practice what they learned.
• 50% of what they learn when engaged in a group discussion.
• 30% of what they learn when they see a demonstration.
• 20% of what they learn from audio-visual.
• 10% of what they learn when they've learned from reading.
• 5% of what they learn when they've learned from lecture.

I agree with the above.
