As National Public Radio (NPR) has announced a second year of its Student Podcast Challenge, grand-prize winners of the first contest reflected in a recent NPR article on how they were affected by the process of creating their winning podcasts. High-school winners in Tennessee say working on their podcast gave them confidence and helped them discover previously unknown passions. The NPR Student Podcast Challenge is open to students in two categories: grades five through eight and grades nine through 12. The official rules, entry guidelines, training tips and resources for teachers and students can be found on the contest's homepage. The site also has lots of support and advice for teachers and students, starting with this video about making good sound from Don Gonyea, a veteran NPR correspondent who has filed stories from all over the world.
