Technology director Myron Rumsey says, “Whiteboards speak to every learning style.”We chose these whiteboards because ...“Promethean’s integrated solution was what we were looking for,” says Rumsey. “The company is focused on educators and listens to teachers.” Rumsey liked that regional consultants work with teachers free. “For a small district, that’s fantastic.”What do you like about the whiteboards?“With whiteboards, teachers have all the tools they need,” says Rumsey. “The whiteboards can adapt to it—even if they change their lessons on the fly.”What don’t you like about the whiteboards?“Like any technology, some teachers have a steeper learning curve and can get frustrated.”Have teachers integrated the whiteboards successfully?“Some teachers use them all day long. Our most seasoned teacher, who has been here 35 years, told me that last year was the most exciting year she’d ever had.”Any advice for schools that are considering whiteboards?“We asked teachers to tell us why they wanted one and how they’d use it. A year later, they showed the rest of the teachers what they were doing. That’s the culture you have to create.”
