To draw students to science, technology, engineering and mathematics fields, schools need to shift focus away from memorization and onto hands-on problem-solving, according to a recent Twitter chat among youth advisers to the USA Science and Engineering Festival. Adora Svitak, a teacher and author, compiled five suggestions from the chat, including allowing students to conduct scientific research, encouraging peer-to-peer learning and taking risks. "Learn by doing. Education should not be restricted to a classroom or a textbook. Some science and tech concepts only come to life in the lab," noted Param Jaggi, founder of a green tech startup.
