How to Use Different Points of View in Your Story

Teri, a blog reader, sent in a great question about points of view.  I've gotten variations of this question often in my online classes.  Teri's two narrators switch back and forth, alternating chapters. 

She wondered if she needed to make their amount of chapters equal.  Does she need as many chapters from her male character's point of view as from her female's?

Variations of this question crop up often in my online classes.
