Michael Rosen explores the new wave of public-speaking events including Ignite and TED, and asks if the culture of 'Show & Tell' in American classrooms produces better public speakers.

He visits the American Museum in Britain and speaks to their Head of Learning, Laura Brown about what's influenced the nation's approach to public speaking, and how a sense of optimism drives their passion to share ideas.

He also speaks to Chris Anderson about how he attracted such big names to speak at the TED events, and how it's grown into a global community of public speaking. Plus there's an interview with Amanda Timberg from TeachFirst about the way 'Show and Tell', 'Hot Seat' and TED talks all feed into their working practises.

Ignite has been described as a "gig for speakers" and event organiser Andy Kervell describes the challenges of both putting together a five minute talk backed by twenty slides, and then delivering it to a rowdy and excitable crowd. Some of the speakers including Sky at Night presenter Dr. Chris Lintott explain why they enjoy taking part in these events.
