Thematic Approach

Talking to a humanity teacher I was envious of how much flexibility they have in what they cover. After feeling sorry for myself I started to think we can do the same in Econ. Lets call it the novelist's approach to setting up a class. Or to make it sound more formal "The Thematic Approach to Economics".
This is a simple idea and probably some education book has this:

1. Picking a main theme for the semester such as growth or in Micro Incentives vs. Costs.
2. Within this theme or framework chose the chapters to be taught

This is how economics textbook authors write! The idea are the same in most textbooks. How it is presented and what is stressed or is not stressed is where the differences among textbook and teachers come to the surface. (this last sentence is really long)
