Groups of students hover around desks in an Oklahoma City Community College classroom, conferring with each other about the math problems on the worksheets in front of them.
Today, the lesson is on factoring equations. Instructors walk from one group to another, talking to each about multiples, products and greatest common factors.
Strictly speaking, this isn't a college-level math class. Credit won't count toward students' degrees, and their GPAs won't reflect how they did.
But experts say courses like this one — and how they're conducted — are a critical factor in whether a student graduates with a degree or leaves college empty-handed.
