Chalk RadioMisinformation, AI, & Science PhotographyScience photographer Felice Frankel is acclaimed for the striking beauty of her images, which have been displayed in museums, published in multiple books, and even featured in the background in one of Ang Lee’s films. Yet she insists that she doesn’t think of herself as an artist. Her academic background is in biology, she began her working life doing cancer research at Columbia University, and she doesn’t see her photographic work as a form of self-expression. Instead, the subtle decisions she makes in setting up a composition, taking the photo, cropping it, and so on, are all in...

What he means by that is that classical economics is built on one powerful explanatory insight: that free markets—networks of buyers and sellers, producers and consumers, weighing the trade-offs of different options and making self-interested choices based on supply and demand—do a better job of deciding how to allocate resources than can be achieved by a top-down, command-economy approach. But as Gruber goes on to explain, that principle only holds when all participants have equal access to mark...

The ideally rational person (“Homo economicus”) assumed by conventional economics always acts in ways that are materially advantageous to them. But Associate Professor Frank Schilbach seeks in his research and teaching to explore the ways in which Homo economicus fails as a model of actual human behavior; in particular, Prof. Schilbach is interested in uncovering the psychological factors that influence people’s choices, even when those choices appear obviously counterproductive and irrational. In this episode, Prof. Schilbach discusses how psychologically-informed interventions can not only...

But Prof. Bob Redwine and Jim Walsh, two of the instructors behind MIT’s Nuclear Weapons Education Project (NWEP), warn that it may not be so unlikely after all, and that failure to take the threat of nuclear war seriously makes it more likely that it will actually occur. Redwine, Walsh, and their colleagues used their expertise from a wide array of fields to create the NWEP and its associated co...

She’s also been involved in teaching calculus to students on campus. To help students become proficient in a notoriously intimidating subject, she has tried to design learning experiences that bridge the gap between the pure abstractions that mathematicians love, exemplified by the use of conventional notation such as x, y, and f(x), and the concrete real-world situations in which calculus is typically applied in other fiel...
2022-06-3013 minChalk RadioAI Literacy for All with Prof. Cynthia BreazealWhen humans interact, they don’t just pass information from one to the other; there’s always some relational element, with the participants responding to each other’s emotional cues. Professor Cynthia Breazeal, MIT’s new Dean of Digital Learning, believes it’s possible to design this element into human-computer interactions as well. She foresees a day when AI won’t merely perform practical tasks for us, but also will provide us with companionship, emotional comfort, and even mental health support. But a future of closer human-AI collaborative relationships doesn’t only require technological development—it also requires us to learn what AI...

(This principle was quickly formalized as GIGO: “Garbage In, Garbage Out.”) What was true in the era of the UNIVAC has proved still to be true in the era of machine learning: among other well-publicized AI fiascos, chatbots that have interacted with bigots have learned to spew racist invective, while facial-recognition software trained solely on images of white people sometimes fails to recognize people of color as huma...

Dealing with topics like these in an introductory graduate-level class can be challenging. You have to train students to read the scientific literature so that they can evaluate the facts on both sides of an issue. But...

And the students do spend much of their time in that new lab. But Dr. John Dolhun, director of the Undergraduate Chemistry Teaching Labs at MIT, who taught 5.310 for many years, and Dr. Sarah Hewett, who currently teaches it, make sure that the course doesn’t take place entirely behind closed doors.

In this episode, Professor Sarma discusses the differences between nominal learning, in which you memorize a fact or procedure but soon forget it, and real learning, in which you can effectively apply the skills and concepts you’ve previously mastered.

As befits a teacher who is also a professional creative writer, he conceives of the academic syllabus as a matrix of interconnected and recurring themes and leitmotifs, not as a schematic outline of self-contained units. In this episode, he describes how he designed his latest class, 11.S947 The Fire This Time: Race and Racism in American Cities, to draw on a wide range of cultural documents—not only written texts but also standup comedy, song, poetry, and film—to de-simplify students’ understanding of racial r...

And that is indeed one of the foremost benefits of OER. But Professor Elizabeth Siler, who teaches at Worcester State University, has found that using OER offers advantages to instructors too: doing so allows you to teach the material you think your students need to learn, and to teach that material the way you think your students need to learn it, rather than being tied to a prepackaged sequence of material. Professor Siler enjoys be...
