"Podcasting is a powerful tool for teaching 21st-century literacy-the literacy of social processes. Not only will students learn technology skills that they can use throughout their lives, but podcasting also connects and applies students' learning to the world around them. Understanding the audience requires students to empathize with others, and developing and posting relevant, engaging podcasts helps students become active, engaged members of society."
