David Lightfoot moves around the classroom with ease. He is in his domain. Lightfoot is the computer lab technician at Creekside Oaks Elementary School in Lincoln. He’s the school’s computer wizard and the kids don’t really notice Lightfoot is in a wheelchair. Lightfoot is an easygoing guy who loves his job, which is helping children understand how to use and be creative with a computer. Five days a week, teachers escort their class of kindergartners to fifth- graders to Lightfoot’s classroom, which is lined with computers, one for each student. For 30 minutes a week, the students have his attention and he has theirs. The projects vary. On a recent Tuesday, the students edited their own video of a musical group performing. Lightfoot rolls up to students’ computers, helping them and answering questions. “Six-hundred-and-fifty kids come through the computer lab each week, four to five classes each day,” Lightfoot said. “I like to start them with typing and the fundamentals. We get into some video editing and PowerPoint presentations.” Creekside Oaks Elementary is one of the only area elementary schools to have a computer teacher and the children respond well to having such a knowledgeable, patient, skilled computer technician in Lightfoot at their school, officials said.
