Bracelets that can store data such as quizzes, homework, presentations and study guides are a twist on keeping students up to speed on schoolwork. SMART Notebook SE bracelets connect to interactive whiteboards and computers via USB ports, and they store information for transfer to students' computers. "Students love them," said a media specialist at a South Carolina middle school. "They love anything that has to do with technology." The bracelets cost about $300 each.
