Legaspi said shy students are benefiting the most. For "a lot of them, what it did is help find their voice," he said. "I have many students that do not participate in my classes or share what's on their mind, so Twitter became that vehicle." Several students praised the new approach. "It's a great way to get people to notice you," said Oscar Lozoria, a shy 14-year-old with long hair that other students used to tease him about. He said Twitter has changed how his peers view him. "They see me as somebody now -- as an equal," he said. Ivan Sabaria, also 14, said Twitter makes learning more fun. "I'm paying attention and doing all my work," he said.
