Dozens of the state’s community, business, government and education leaders combed the campus of Lanier Technical College on Tuesday, observing the way the school implements technology in its classrooms. Through the Georgia Partnership for Excellence in Education’s 20th Annual Bus Trip, about 80 leaders from across the state made their last stop of a four-day “rolling conference” at Lanier Tech, seeing firsthand some of the programs the school offers, including welding, emergency medical training and drafting, and how technology is used to make those courses more effective. “The tour has been absolutely amazing,” said Lauren Eckman, a teacher at the Georgia Academy for the Blind and 2013 Georgia Teacher of the Year.
