"If you can't explain it simply, you don't understand it well enough." - Albert Einstein This is a clear way for me to understand whether or not I thoroughly know the material. If I know my lessons inside and out, then I should have no problem clearly presenting the information.
"If you want to go fast, go alone. If you want to go far, go together." - African Proverb This proverb reminds me of what the objective should be in every learning situation. We can always go much further together. This applies to our online collaboration and our face-to-face communication.
