Chalk Radio

Chalk Radio is the MIT OpenCourseWare podcast, built around conversations between host Sarah Hansen and people connected to OCW's free course material. Several of them teach at MIT. The talk gets specific quickly. Economist Jon Gruber explains opportunity cost through someone who is dating and weighing marriage, then shifts to health care, where the lone hospital on Nantucket faces no competition because patients will not take a ferry for a heart attack. When Hansen asks about his involvement with the Affordable Care Act, he starts from how policy ought to be made: by first understanding what a policy will do. Financial economist Andrew W. Lo considers how poorly people manage their own money and discloses that he has dyscalculia, which he describes as a mathematical counterpart to dyslexia. He also recalls learning that good drugs can fail to reach patients because there is not enough financing. He calls his turn toward that problem selfish, since he wanted better drugs for friends and family. MIT programmer and senior lecturer Ana Bell talks about Python, growth mindset and, somehow, rubber ducks. Science photographer Felice Frankel holds that an image's first job is to communicate the science. She walks through her tools, including a scanner she treats almost like a microscope, with 3D objects placed on it and the lid left up. One question keeps coming back: what does AI change? Hansen asks Frankel whether it is coming for her job, asks Bell whether learning to code still makes sense, and asks Lo whether ChatGPT should plan a retirement. Bell's reply, 'trust, but verify', rests on fixing a flawed AI-generated program herself instead of prompting the tool over and over. Hansen is a lively presence throughout. She interrupts Bell to insist that her programming knowledge is more than basic, and she wonders aloud whether she belongs in economics once Gruber says its standard model leaves no room for emotion. The feed also steps outside the faculty interview. In 'Special Episode: Collaborating with Community Colleges', Hansen talks with the OCW team's collaborations and engagement manager. That guest came to see the work as listening to community college faculty about their priorities, not simply handing them OCW, and found that adapting open material is not plug and play. One example is a mechanical engineering professor named Tricia, who spent time reworking complex engineering graphs for her own teaching. 'Sujood from Sudan: An Open Learner's Story' comes from Open Learners, a series in which two learners, one from Kampala and one from Memphis, talk with other people who use OCW. The guest credits OCW lectures with helping them understand academic English, and describes how meeting others affected by war helped with healing. Episodes close by pointing to OCW and to a video version on the MIT OCW YouTube channel, so a listener can go from a conversation to the material behind it.
