  • In this episode we meet professor and Nobel laureate Esther Duflo and her colleague Dr. Sara Ellison for a discussion about economics: what it is, how it differs from sociology, how it incorporates classic intellectual tools like probability and statistics with newer technologies like machine learning, and how it can itself be a tool for improving the world by solving problems of inequity one problem at a time. As Duflo and Ellison explain, economics has shifted in recent decades from a primarily solo endeavor to an intensely collaborative one, in which any given paper is likely to have multiple co-authors but also to be based on the work of an even larger group of people—not only professional economists but also psychologists, teachers, NGO workers, and so on. (Fittingly, Duflo’s and Ellison’s teaching is collaborative as well; they work together as co-instructors on the course 14.310x Data Analysis for Social Scientists, available on both MITx Online and MIT OpenCourseWare.) Other topics covered in the episode include why online shopping isn’t as cheap as it seems like it should be and why you should disable some of your spreadsheet’s default settings.

  • This conversation with Prof. David Kaiser, who teaches physics and the history of science at MIT, covers a vast timespan, from the beginning of the universe to the present day. Prof. Kaiser explains that inflationary cosmology helps connect our understanding of quantum fluctuations—what he calls the “jitters” that particles undergo at subatomic levels—to the irregular distribution of matter in the universe. What’s most exciting, he says, is that simulations based on inflationary theory produce predictions that closely match detailed measurements of the cosmos. Later in the interview, Prof. Kaiser discusses how he teaches his course on 20th-century science, seeking to demythologize Albert Einstein (“He was no Einstein as a young person!”) and examining the historical context of the development of nuclear weapons as portrayed in the 2023 film Oppenheimer. He hopes his students will learn to see science not as happening in isolation but as a product and producer of historical events and cultural changes. Lastly, he discusses what he’s learned from his years of teaching the course, and in particular how he helps students who are anxious about writing papers to overcome their fears.

  • Paradoxically, urban planning professor David Hsu doesn’t consider himself a “city person,” but he has great appreciation and enthusiasm for cities as places where meaningful steps can be taken toward climate mitigation. In this episode, Prof. Hsu explains that urban planners can help move cities to take action to reduce the amount of greenhouse gas emissions from the construction, heating, power, and transport sectors. But he observes that the most lasting and successful actions are ones that are implemented democratically, with the consent and participation of the affected communities. To win over those communities, he says, technical experts have to learn to communicate solid facts using math that even a layperson can follow. And they need to learn that sometimes there can be more than one defensible position in response to a given problem—which is why Prof. Hsu often asks his students to read multiple papers that take conflicting positions on a particular problem, and to evaluate which paper’s (or papers’) arguments are more persuasive. Because in the end, it’s people who need to be persuaded to take action against climate change—solutions won’t implement themselves.

  • You don’t need a multibillion-dollar supercollider to detect subatomic particles. In fact, you can build a working cloud chamber—a device capable of revealing the cosmic radiation and radon decay events that go on continuously around us—with just a block of dry ice, some rubbing alcohol, and a few objects you probably already have in your kitchen. What’s more, constructing the cloud chamber only takes about an hour, making it an ideal project for an introductory physics class, for intellectually engaged nonscientists, or even for curious kindergartners (with some adult supervision!). In this interview, engineering professor Anne White discusses the pedagogical usefulness of such hands-on activities—and at the other end of the spectrum, she describes her enthusiasm for a much, much larger physics project, the decades-long effort to put nuclear fusion to practical use as a source of clean power for the world. The interview also touches on Prof. White’s experience of mentorship, both as mentee in her youth and as mentor now, and on the formative influence of childhood toys in paving the way for the kind of creative goal-driven tinkering that nuclear scientists and engineers practice.

  • We first interviewed Professor Michel DeGraff back in season 1; he now returns for another episode, diving deeper into issues of culture and identity. He talks about his childhood in Haiti, where he was punished at school for speaking his own mother tongue, and where he was taught by his teachers and even his parents that Kreyòl was not “a real language.” After doing early work in natural language processing that led him to question widespread assumptions about language, Prof. DeGraff shifted his academic focus to linguistics. He now begins each iteration of his course 24.908 Creole Languages and Caribbean Identities by asking his students to write linguistic autobiographies that describe the languages they grew up speaking and examine their own attitudes about language. In addition to discussing that course, he talks in this episode about his efforts to draw attention to language’s role in perpetuating imbalances of power. As an added bonus, we hear from two students from 24.908, discussing how Prof. DeGraff helped cultivate trust in the classroom, and how that trust freed the students to enrich each other’s understanding of the world by sharing personal experiences and insights.

    *English Translation of Prof. Michel DeGraff’s Kreyòl Statement:

    So, my fellow countrymen,

    There's something that is very VERY important to understand:

    we must understand the origins of prejudices against Kreyòl.

    We must also remember that Dessalines said, so clearly,

    that everyone is human. And he also knew that,

    if everyone is human, then every language is a perfectly normal language.

    So Kreyòl, too, is a perfectly normal language.

    That's why he said, since before 1804,

    that Kreyòl is our own language,

    so we don't need to always look for other languages to speak.

    Yes, we must remember, if we did not have Kreyòl as a language,

    we could never have succeeded in making this revolution

    that gave us an independent Haiti.

    Kreyòl was the language of the revolution.

    So, today, we must use

    Kreyòl too as language of instruction.

    It is this language that will allow all children in Haiti

    to access quality education as their right.

  • Many people associate the word “sustainability” with a few specific activities such as composting or recycling. Our guests for this episode, Dr. Liz Potter-Nelson and Sarah Meyers, point out that sustainability is actually much broader, encompassing all the future-oriented practices that promote the continued flourishing of individuals, cultures, and life on earth. Dr. Potter-Nelson and Meyers have sought not only to make education a tool for sustainability but to make it a sustainable activity itself. In this episode, they describe how they created the Sustainability and Climate Change Across Learning Environments (SCALES) project, a curated repository of open-source, easily adaptable educational resources, many of them originally adapted from course materials on MIT OpenCourseWare. These resources, which are categorized according to a set of six main pedagogical approaches and six chief competency areas, draw from a surprisingly wide range of academic fields, but each was selected for its potential to support sustainability in the classroom and in the world. After all, Dr. Potter-Nelson and Meyers say, sustainability is an inherently interdisciplinary subject, one that can inform–and be informed by–teaching in nearly any field of study.

  • Nobody comes into this world already knowing how to teach—and most students arrive at undergraduate or graduate programs without any teaching experience at all. For those who are selected to be teaching assistants, the prospect of facing a classroom of students for the first time can be terrifying. To assuage those fears and provide pedagogical skills, the Biology department at MIT runs a training program for new TAs; our guest Dr. Summer Morrill helped develop the curriculum for that program, as well as serving as an instructor in it. In this episode, Dr. Morrill describes how she designed the content of the training program to reflect the specific challenges Biology TAs typically face in their first semester. Among the topics she discusses are the importance of empathy and inclusiveness in classroom teaching, how the same habits of thought that make effective biologists can also make especially effective teachers, and ways in which the course materials from the training program (which she is sharing in a forthcoming supplemental resource on OCW), would lend themselves to being usefully adapted for training TAs in other disciplines and at other institutions.

  • In this episode we meet Haynes Miller, Professor Emeritus of Mathematics, who in his 35+ years of active teaching at MIT has done much to shape the institute’s math curriculum. Prof. Miller’s special focus is algebraic topology, but his teaching has encompassed a wide range of other topics from differential equations to number theory, and he has a special interest in teaching undergraduates. Join us as Prof. Miller discusses math education with guest host Paige Bright, a current MIT third-year student who was one of his students in a first-year seminar and who has since acquired teaching experience of her own as the instructor for the course Introduction to Metric Spaces during the Independent Activities Period in January 2022 and 2023. Among the topics they cover in this discussion are the importance of communication in mathematics, Prof. Miller’s use of computer manipulatives (which he calls “mathlets”) to engage students more actively, what “lab work” means in the context of pure mathematics, how instructors from different institutions have come together online to discuss ways to improve undergraduate math education, and what happens when you ask students to switch roles and become teachers.

  • Eric Grimson is MIT’s chancellor for academic advancement and interim vice president for Open Learning; he’s also a longstanding professor of computer science and medical engineering. In this episode, Prof. Grimson shares his thoughts on in-person and online education. We learn that he rehearses each lecture one, two, or even three times before coming to the classroom, and that he often pauses in his speech when lecturing to avoid distracting his students with “um”s and “ah”s and similar disfluencies. But though some of the techniques he describes might seem to reflect a view of teaching as performance, Grimson firmly believes that education should be a dialogue rather than a monologue—that students should be engaged as partners in the exploration of the material, even in an introductory-level class. “Anybody with enough curiosity ought to be able to explore a field,” he says, “and we ought to be able to teach at a level that opens it up to them.” The same conviction underlies his commitment to sharing his expertise online, whether by publishing his course materials on MIT OpenCourseWare or through purpose-built MOOCs on MITx. [Warning: this episode also includes numerous bad jokes!]

  • MIT has long been an innovator in online education. For even longer—for its whole history, in fact—it has championed hands-on learning. These two emphases may seem incompatible, but the MICRO initiative draws on both in an effort to increase diversity within the field of materials science. Dr. Jessica Sandland and Dr. Cécile Chazot, our guests for this episode, describe how MICRO recruits undergraduates from minoritized backgrounds to do impactful research remotely in collaboration with MIT researchers. Dr. Sandland and Dr. Chazot see this collaboration as a mutually beneficial relationship: the MICRO students gain valuable experience in cutting-edge research, as well as an introduction to a field they may not have had the opportunity to study previously, while the MIT researchers benefit both from the students’ work on the projects and from the fresh perspectives they bring to the field. In this episode, we also hear how MICRO supports participants’ professional development with guidance from “near-peer” grad-student mentors, who provide help not only in technical matters but also in developing soft skills such as writing abstracts or defining questions for research.

  • Do you always make the best possible choices, even when you’re stressed or short on sleep? 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 boost people’s productivity, earnings, and savings, but can even increase their tendency toward benevolence and cooperation. As he puts it, while economists have not ignored mental health altogether, they have tended to view it instrumentally, in terms of its effects on productivity or financial stability. It would be better, he suggests, to view mental health as valuable for its own sake, as an inherent element of overall well-being–which is why he prioritizes students’ mental health by making assignments due not first thing in the morning but at 6 or 8 PM!

  • To most people, especially those who are too young to remember the Cold War, the possibility of nuclear Armageddon may seem so remote as not to be worth contemplating. 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 course 8.S271 Nuclear Weapons – History and Prospects. Together, the course and the project website represent an interdisciplinary effort to educate nonspecialists on the science, technology, and history of nuclear weapons, along with present efforts to prevent nuclear proliferation and to reach international agreements to reduce the likelihood of a world-devastating conflict. In this episode, we hear how the bombings of Hiroshima and Nagasaki changed geopolitics forever, how a well-intentioned nuclear doctrine may have disastrous unintended consequences, and why understanding the topic of nuclear weapons requires an interdisciplinary approach.

  • Professor Gigliola Staffilani, who teaches in MIT’s Department of Mathematics, was closely involved in designing and teaching the introductory-level 18.01 Calculus I course series now found on the MIT Open Learning Library. 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 fields such as chemistry or physics. In this episode, Prof. Staffilani discusses her efforts to make calculus less abstract and more intuitive for learners–efforts that draw on a diverse mix of teaching tools and props: digital applets, sketching tools, bagels, croissants, donuts, and even a balloon in a box. She also discusses her commitment to increasing equity and fighting implicit bias in her field.

  • Though there’s widespread consensus that the slavery and colonization that characterize the history of European relations with Africa represent a legacy of grave injustice, there is much less agreement on how to redress that injustice. Professor M. Amah Edoh, who teaches in MIT’s Department of Anthropology, designed the course 21A.S01 Reparations for Slavery and Colonization with the goal of honestly facing the historical record and openly discussing how best to respond. Because she believes expertise is too often conceived of as something that flows “north-south” from the developed nations toward the developing world, she structured the course to embrace expertise wherever it might be found—recruiting guest lecturers from various disciplines and from institutions around the world, as well as activists currently involved in the quest for reparative justice. She even went a step further, sharing the lecture videos on YouTube while the semester was still ongoing and inviting viewers to contribute their own insights into how to deal with the ongoing legacy of historical wrongs. In this episode, Prof. Edoh describes the motivation for this innovative course structure and reflects on the challenges of grappling with such a sensitive subject.

  • When 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 is capable of and how to interact with it in a more informed way. To further this goal, Professor Breazeal leads the Responsible AI for Social Empowerment and Education (RAISE) initiative at MIT, which runs an annual “Day of AI” program to promote better understanding of AI in the next generation of technology users and developers. In this episode, she describes those projects as well as her work developing the groundbreaking social robots Kismet and Jibo, prototypes of what she calls “warm tech”—AI-enabled devices designed to be engaging, expressive, and personal.

  • In the previous episode we learned about a project undertaken as part of the Social and Ethical Responsibilities of Computing (SERC) initiative at MIT’s Schwartzman College of Computing. In this episode we hear about another SERC project, from Prof. Daniel Jackson and graduate teaching assistant Serena Booth, who have partnered to incorporate ethical considerations in Prof. Jackson and Prof. Arvind Satyanarayan’s course 6.170 Software Studio. Jackson and Booth explain that software can fail its users in three ways: First, it can simply work badly, failing to meet the purpose it was intended for. Second, it may do what the user wants it to, while simultaneously accomplishing some insidious purpose that the user is unaware of. Third, as Prof. Jackson puts it, it may “contribute to a computational environment that has subtly pernicious effects” on the individual or on society—effects unintended not only by the user but also by the software designer. In their revised syllabus for 6.170, Jackson and Booth attempt to address these second and third types of failure by introducing ethical concerns early in the course and by sharing an ethics protocol to scaffold students’ decision-making throughout the software design process.

  • When computer science was in its infancy, programmers quickly realized that though computers are astonishingly powerful tools, the results they achieve are only as good as the data you feed into them. (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 human. In this episode, we meet Prof. Catherine D’Ignazio of MIT’s Department of Urban Studies and Planning (DUSP) and Prof. Jacob Andreas and Harini Suresh of the Department of Electrical Engineering and Computer Science. In 2021, D’Ignazio, Andreas, and Suresh collaborated as part of the Social and Ethical Responsibilities of Computing initiative from the Schwarzman College of Computing in a project to teach computer science students in 6.864 Natural Language Processing to recognize how deep learning systems can replicate and magnify the biases inherent in the data sets that are used to train them.

  • Most of the students in Professor Dennis McLaughlin’s course 1.74 Land, Water, Food, and Climate come to it with established opinions on some very controversial topics: whether GMOs are safe, whether climate change is real (and really human-induced), whether organic agriculture is preferable to conventional agriculture, and whether it’s better for land to be worked by individual farmers or by larger corporations. 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 you also have to strike a balance between those concrete facts and the intangible social values that enter into debates on sensitive topics. In this episode, Professor McLaughlin describes his approach to those two challenges in teaching 1.74; he also explains how a diversity of backgrounds among the students in the class enriches class discussion, and he describes what he sees as the teacher’s role: to adjust and when necessary reframe the terms of discussion, while still allowing students the freedom to explore the ramifications of their ideas.

  • Students in MIT’s course 5.310 Laboratory Chemistry have a state-of-the art lab to work in, with energy-saving hibernating fume hoods and a new spectrometer that achieves mind-blowingly precise measurements—not parts per million or parts per billion, but parts per trillion! 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. One of the lab activities involves collecting water samples from the Charles River and analyzing them for dissolved oxygen and contaminants such as phosphates. This activity, named the “Ellen Swallow Richards Lab” after an environmental chemist who was also the first female student at MIT, ensures that the coursework is grounded in real-world concerns. In this episode, Dr. Dolhun and Dr. Hewett discuss that lab and other topics, such as how to teach perseverance, why their course emphasizes ways of communicating science to an audience of nonscientists, and the importance of sharing educational resources.

  • Sanjay Sarma is not only a professor of mechanical engineering; he’s also Vice President for Open Learning at MIT, where he oversees innovative efforts to reimagine education, and he is coauthor (with Luke Yoquinto) of the recent book Grasp, which explores the nature of learning. 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. When the format of education is consistent with what science tells us about how our brains store and retrieve information, Sarma says, real learning can be optimized. He argues that well-designed platforms for online learning are a vital resource for people worldwide who lack access to in-person education—like a glass of water to someone in a desert. But he also sees online learning as an indispensable tool for in-person education, allowing innovations that help to maximize the value of students’ and instructors’ time together, and he is optimistic about the potential value of online learning credentials as a pathway toward in-person degrees.
