A US television show designed to raise the image of engineering among children was an experiment when it first aired a year ago. The show, Design Squad, pits two teams of teenagers against each other in competitions to design and build sometimes whimsical, sometimes serious structures and machines. There's evidence that the show reaches kids. The producer, WGBH, hired Goodman Research Group Inc for a study of 139 fifth- and sixth-grade students in Massachusetts and California. More than half of them were girls. After watching four episodes, students were significantly more likely to agree that engineers help make people's lives better and that they solve problems affecting real people.
