Have you ever noticed how much more enjoyable it is to learn something when you're actually doing it?  That's the joy of situated learning!  It's like learning to bake a cake by actually baking one, not just reading a recipe.

You have built towers with blocks, right? You know, LEGO, DUPLO, or any of the gazillion other types of blocks. At first, you stack them however you want. Your tower falls over if it gets too high. So, you start over, determined to build it so it stays upright. The more you build it, the higher you can go without it falling over. You learn what works and what doesn’t. Your learning transforms, which is a fancy way of saying it changes.
