Our series, "In Case You Missed It," dives into topics you maybe wish you'd learned in school. We speak with leading experts and educators so we can help catch you up.

Critical thinking skills are at the heart of media literacy – and there's a movement to make media literacy a requirement in schools across the country.

And if you didn't learn it in school, what do you need to know now? Want to support 1A? Give to your local public radio station and subscribe to this podcast. Have questions? Find us on Twitter @1A.
