COLUMBUS, Neb. (AP) — A new approach has flipped the conventional schoolwork structure in some Columbus Middle School classes.

Students watch lectures at home online and do their homework in class. The setup was started last school year by a teacher who used to teach sixth-grade math. This year Joni Ebel and fellow math instructor Shantelle Suiter are trying the concept.

Principal Amy Haynes says the flipped classroom model has been growing in use in districts around the nation. She says “it gets kids engaged.”

The teachers make videos of 10-15 minutes, explaining the latest lessons. Students download an app to watch the videos outside of classes and take notes and copy down problems that are explained to them. In class they do homework under the teacher’s supervision.
