OMAHA, Neb. (AP) — The Omaha school district has changed student conduct code to allow cellphone use during lunch or between classes.

The Omaha World-Herald (http://bit.ly/1Ipm8tf ) reports that the school board last week approved the new guidelines for high school students. The district previously required students to keep their phones off during the school day unless it was an emergency or had received special permission.

Elementary and middle school students still have to keep their phones inside lockers or backpacks and they must be off during the school day.

The district hopes the change in rules encourages more teachers to incorporate technology such as smartphones into lesson plans.
