Students love Khan Academy?

7. Of course.

I particularly like the contrast between "so boring" and "steps were left out."

Put in all the steps for one kid, and you bore another. Leave out the steps to avoid boredom for one kid and you lose another kid.

Put in all the background knowledge necessary and you bore many kids or leave them feeling overwhelmed. Leave it out and you lose many kids.

On-line learning requires that the students be motivated to figure out what they didn't get and take steps to fill in the gaps.

The reason schools usually use on-line learning is to help students who aren't getting it in the classroom, and that's usually because of lack of motivation and often a lack of curiosity.
