With another long hot American summer coming to a close, many students are scrambling to get back into “learning mode” before school starts. One of the simplest ways to ease that transition is with podcasts. Whether your passion is American History or Algebra, there’s probably an educational podcast out there for you.
While these programs probably won’t mirror your lesson plan, they will explore topics covered in class. Below is a sampling of some of the exceptional podcasts that both teach and entertain. Best of all – they’re free. Read on for your “2010 Downloading Curriculum.”
Science

Radiolab investigates some of world’s most intriguing scientific questions in a unique conversational format. Recent episodes have examined the importance of words in human development and time. First time listeners will probably notice that the show also just sounds different.
Before becoming a radio producer, Jab Abumrad, one of Radiolab’s creators, was as an experimental musician. Abumrad’s passion for ProTools is apparent in the show’s textured soundscape, which is layered with a variety of sound effects and quick edits. Perhaps the show’s only downside is its frequency. There are only a handful of episodes every season because one Radiolab episode requires months to produce.
Outlet: WNYC, New York City’s Public Radio Station
Time: An Hour
Frequency: 5-6 every season
Additional Listening: The Naked Scientists Podcast
History

In Dan Carlin’s Hardcore History, Carlin, a veteran journalist turned podcaster, dissects the textbook version of events. In shows that often run over an hour, the host passionately retells some of history’s best stories.
Hardcore History has become one of the most downloaded podcasts on iTunes, and Carlin’s widespread appeal can also be attributed to his insight. One podcast asked, “Could widespread child abuse in earlier eras explain some of history’s brutality?” Another show was based off the question, “Does the toughness of peoples play any role in history?” Don’t let the name fool you; all material is appropriate for younger listeners.
Outlet: Dan Carlin
Time: 1 – 1 1/2 hours
Frequency: 5-6 every year
Additional Listening: Stuff You Missed in History Class
Economics

Planet Money is NPR’s podcast on global economics and business. Initially created by veteran public radio reporters Alex Blumberg and Adam Davidson to explain the recent financial crisis, the show quickly became one of the most popular and praised podcasts available.
Planet Money’s success lies in how it tackles complex subjects with great storytelling. A financial instrument like a Collateralized Debt Obligation (CDO) may sound impossibly boring, but Planet Money routinely makes these types of things the heart of a thrilling narrative. The team continues to explore the financial collapse, but they’ve expanded their scope to include all aspects of the global economy.
Outlet: NPR
Time: 15-30 minutes

English

For those of us who couldn’t make it through Wuthering Heights, Cliff Notes Cramcast would have been a lifesaver. This free podcast reviews some of the stuff you need to know for the big test and does it in three to four minutes. Of course, these podcasts can’t cover every detail. To do that, you would — you know — need to read the book.
Outlet: Cliff Notes
Time: 15-30 minutes
Frequency: Twice a week
Additional Listening: Grammar Girl Quick and Dirty Tips
Foreign Language

The Internet is full of podcasts that cater to students learning foreign languages. For those interested in the major European languages, Radio Lingua is a good bet. Another reliable hub is Open University, which in addition to the European languages also has a set of Mandarin podcasts. These outlets are mainly for beginners or students who need a quick review. Both are rated highly on iTunes by users.
Outlets: Radio Lingua and Open University
Time: 15-30 minutes
Frequency: Lesson plan
Additional Listening: Other reliable podcasts include Discover Spanish and Learn French.
Math

For those of us who struggle to calculate a 15% tip, The Math Dude’s podcast is a must-listen. Every week, affable nerd Jason Marshall explains basic concepts like how to calculate the area of an object or how to add faster. When Marshall isn’t podcasting, he researches “infrared light emitted by starburst galaxies and quasars” at Caltech, which just means his left-brain knows what’s up.
Outlet: Quick and Dirty Tips
Time: About 7 minutes
Frequency: Weekly
Additional Listening: Mathgrad.
Current Events

Every Sunday, comedians Andy Zaltzman and John Oliver recap the week’s events in The Bugle, a satirical podcast that is easily one of the funniest listens on the Internet. Think an audio version of The Daily Show, where Oliver is also a regular. The Bugle’s focus tends to be on the biggest international news, but the duo’s separate locations – Zaltzman in London and Oliver in New York City – ensure a focus on the English-speaking world’s antics. Although the pair has a leftward slant, there are no sacred cows. The Bugle even takes aim at itself in its tagline: “An audio newspaper for a visual world.”
Outlet: The Times (UK)
Time: 30 minutes
Frequency: Weekly
Additional Listening: NPR News, BBC World Service
