With the total solar eclipse expected Aug. 21, Hall County teachers are getting digital resources developed by school district educators to help them teach students about the once-in-a-generation phenomenon before and during the event. Eddie Millwood, principal of C.W. Davis Middle School and digital convergence specialist for the school district, presented a synopsis of the materials to the school board Monday night. He said teachers should have access to those materials by Tuesday afternoon. The Hall County and Gainesville school systems have chosen to extend the day by an hour on Aug. 21 so that students can experience the eclipse in the school environment.
