Saying It != Learning It

I have been running into this problem a lot both at work and with various web sites. You can't teach your audience anything simply by making a statement.

For example, I am going to teach you the theory of relativity and everything you need to know about relativistic physics:
E = MC2

Got it! Good. Let's move onto the next subject.... :)

Are you an expert on relativity? Of course not. Without doing the real math behind the equation, you don't really understand anything. There cannot be learning without practice.

Or let's take riding a bike. I could have you read a book on bike riding. Show you videos demonstrating bike riding. Watch a bike race. Any number of things. But you will never learn to ride a bike until you climb on and pedal.

So when you are writing content, at a minimum, include examples your audience can look at, download and explore. Saying it != learning it.
