Opening Computer Science to Everyone with Chancellor Eric Grimson

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.

Seeing Green with Drs. Sandland and Chazot

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.  Relevant Resources:MIT OpenCourseWareThe OCW Educator PortalMICRO resource on OCWMentoring worksheets: Defining a Research Project and Aligning Expectations (PDF)Planning and Managing Remote Research Tasks (PDF)Effective and Inclusive Communication in Remote Mode (PDF)Fostering Independence (PDF)Establishing a Network of Mentors: The Mentoring Map (PDF)  Abstracts of research by MICRO participantsApply to MICRODr. Sandland’s faculty pageDr. Chazot’s websiteMusic in this episode by Blue Dot Sessions Connect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

Well-being is the Goal with Prof. Frank Schilbach

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!Relevant Resources:MIT OpenCourseWare The OCW Educator Portal Professor Schilbach’s behavioral economics course on OCWProfessor Schilbach’s faculty pageProfessor Schilbach at the Abdul Latif Jameel Poverty Action LabMusic in this episode by Blue Dot SessionsConnect with Us:If you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

Visualizing Calculus with Professor Gigliola Staffilani

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.Relevant Resources:MIT OpenCourseWareThe OCW Educator PortalShare your teaching insightsProfessor Staffilani’s faculty pageSingle variable calculus courses on MIT’s Open Learning Library18.01 Calculus I: Single Variable Calculus on OCWMusic in this episode by Blue Dot Sessions Connect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

Finding Expertise Everywhere with Prof. M. Amah Edoh

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.Relevant Resources:MIT OpenCourseWareThe OCW Educator PortalShare your teaching insightsProfessor Edoh’s faculty pageCourse materials by Professor Edoh on OCW21A.S01 Reparations for Slavery and Colonization on OCWOpen Learning story on 21A.S01OCW YouTube playlist for 21A.S01Africa’s Expertise (YouTube lecture by Prof Edoh)African Futures Action LabHow Africa Has Been Made to Mean (2020 episode of Chalk Radio)Music in this episode by Blue Dot Sessions Connect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

AI Literacy for All with Prof. Cynthia Breazeal

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. Relevant Resources:Day of AIRAISE (Responsible AI for Social Empowerment and Education)MIT OpenCourseWareThe OCW Educator PortalShare your teaching insightsProfessor Breazeal’s faculty pageProfessor Breazeal named Dean of Digital LearningProfessor Breazeal introduces Jibo (YouTube video)The Rise of Personal Robotics (TED talk by Professor Breazeal)Music in this episode by Blue Dot Sessions Connect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

Making Ethical Decisions in Software Design with Prof. Daniel Jackson & Serena Booth

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. Relevant Resources:MIT OpenCourseWareThe OCW Educator Portal Share your teaching insightsSocial and Ethical Responsibilities of Computing (SERC) resource on OpenCourseWare6.170 Software Studio ethics assignmentsSERC websiteProfessor Jackson’s faculty pageSerena Booth’s personal websiteMusic in this episode by Blue Dot SessionsConnect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

The Human Element in Machine Learning with Prof. Catherine D’Ignazio, Prof. Jacob Andreas & Harini Suresh

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. Relevant Resources:MIT OpenCourseWareThe OCW Educator PortalShare your teaching insightsSocial and Ethical Responsibilities of Computing (SERC) resource on OpenCourseWareCase Studies in Social and Ethical Responsibilities of ComputingSERC websiteProfessor D’Ignazio’s faculty pageProfessor Andreas’s faculty pageHarini Suresh’s personal websiteDesmond Patton’s paper on analysis of communications on TwitterMusic in this episode by Blue Dot Sessions Connect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.

When There Isn't A Simple Answer with Prof. Dennis McLaughlin

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.  Relevant Resources:MIT OpenCourseWareThe OCW Educator PortalShare your teaching ideas and insights with Dennis McLaughlinProfessor McLaughlin’s course on OCWProfessor McLaughlin’s faculty pageOther environment courses on OCWThe MIT Climate PortalConnect with Curt Newton at LinkedIn or TwitterMusic in this episode by Blue Dot Sessions Connect with UsIf you have a suggestion for a new episode or have used OCW to change your life or those of others, tell us your story.
