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.

Learning about Life through Laboratory Chemistry with Drs. John Dolhun & Sarah Hewett

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. Relevant ResourcesMIT OpenCourseWareThe OCW Educator PortalShare your teaching ideas and insights with John Dolhun and Sarah HewettDr. Dolhun and Dr. Hewett’s course on OCWChemLab Boot Camp video series on OCWEllen Swallow Richards biography at WikipediaMIT Spectrum article on the new undergraduate chemistry labsMIT News article on energy-saving measures in the undergraduate chemistry labsMusic 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.

Re-engineering Education with VP for Open Learning Sanjay Sarma

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.Relevant Resources:MIT OpenCourseWareThe OCW Educator PortalSanjay Sarma & Luke Yoquinto’s xTalk on GraspProfessor Sarma’s course on OCWProfessor Sarma’s faculty pageProfessor Sarma at MIT Open LearningProfessor Sarma’s book GraspMicromasters programs from MITxMusic in this episode by Blue Dot Sessions Connect 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.

Sketching a Picture of the Mind with Prof. Nancy Kanwisher

Nancy Kanwisher, founding member of the McGovern Institute for Brain Research and professor in MIT’s Department of Brain and Cognitive Sciences, describes the effort to understand the mind as “the grandest scientific quest of all time,” partly because it seeks to answer fundamental questions that all people ponder from time to time: What is knowledge? How does memory work? How do we form our perceptions of the world? In this episode, Prof. Kanwisher gives a nutshell history of her field and describes how scientists use imaging techniques to study the brain structures involved in different cognitive skills. She also reflects on the usefulness of personal anecdotes as a teaching technique in courses like her 9.13 The Human Brain. Kanwisher believes scientists have a moral obligation to share the results of their research with the world—which may explain why she has published her course materials for 9.13 on OpenCourseWare—but she doesn’t see that sharing as an onerous responsibility. “The stuff I do is easily shareable with people,” she says, “but it’s also fun. It’s really fun to get an idea across and see somebody resonate to it.”Relevant ResourcesMIT OpenCourseWareThe OCW Educator PortalShare your teaching ideas and insights with Nancy KanwisherProfessor Kanwisher’s course on OCW (9.13 The Human Brain)Professor Kanwisher at MIT’s McGovern Institute for Brain ResearchProfessor Kanwisher’s series of short videos on brain scienceMusic 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.

Building Our Muscle for Democracy (Prof. Ceasar McDowell)

The classic New England town meeting, with voters gathered in a large hall to decide issues directly, is often cited as the purest form of American democracy. But historically, those town meetings gave a voice only to certain classes of people. In this episode we meet Ceasar McDowell, Professor of the Practice of Community Development at MIT and newly appointed associate director of MIT’s Center for Constructive Communication. Prof. McDowell has devoted his career to nurturing a more vibrant, inclusive democracy, one adapted to the complex reality of a modern, largely urbanized America. In his course 11.312 Engaging Community (coming soon to OpenCourseWare), he helps his students use the tools of civic design to craft forms of community engagement and decision-making that will bring everyone into the conversation, even those on the margins of our society. In keeping with his commitment to collaborative effort, Prof. McDowell encourages his students to propose specific real-life problems they’re interested in, and to decide collectively which ones to address in the class. “We have to learn to talk to each other,” he says. “Yes, this is hard work, and yes, you can do it.” Relevant Resources:MIT OpenCourseWareThe OCW Educator PortalProfessor McDowell’s faculty pageMIT's Center for Constructive CommunicationWe Who Engage (blog)We Who Engage (podcast episodes)We Who Engage (Instagram)America’s Path ForwardCivic Design FrameworkMusic 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.

In Climate Conversations, Empathy is Everything (Brandon Leshchinskiy)

In our previous episode we met Professor Dava Newman, cofounder of the nonprofit group EarthDNA. Today’s guest is Brandon Leshchinskiy, a graduate student in Technology and Policy at MIT’s Institute for Data, Systems, and Society, who has helped Prof. Newman create the EarthDNA Ambassadors program, training young people in communication, negotiation, and storytelling to build support for individual and collective action on climate change. Leshchinskiy has crafted an engaging interactive presentation, called Climate 101, that creatively employs materials from various sources to examine climate change from scientific, economic, and civic perspectives. By teaching young people to deliver this presentation effectively, he is developing a cohort of trained climate educators who can in turn teach their peers to reach out to friends and family on one of humanity’s most pressing issues. In this episode, Leshchinskiy discusses why young people make effective climate ambassadors, how climate presentations can be made more powerful by customizing them with specific details that are relevant to people’s own communities, what we can learn from society’s response to the challenges of Covid-19, and how to avoid developing “doom fatigue” from exposure to negative news stories.Relevant ResourcesMIT OpenCourseWareOCW’s 20th anniversary celebration registration pageThe OCW Educator PortalEarthDNA on the WebEarthDNA’s Climate 101 on OCWEarthDNA Ambassadors programWangari Maathai (Nobel Peace Prize winner)“I will be a hummingbird” (YouTube video)Professor Dava Newman at MIT’s Institute for Data, Systems, and SocietyRand Wentworth at Harvard’s Center for the EnvironmentMusic 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.

Visualizing the Future of Spaceship Earth (Prof. Dava Newman)

Professor Dava Newman is an aerospace engineer whose career has largely focused on developing improved space suits for eventual interplanetary travel. But in recent years she has turned her sights back toward Earth, using the vast amounts of data collected by satellites in near space to inform and motivate the public for the fight against catastrophic climate change. In this episode, Prof. Newman fields listener-submitted questions about climate change and also talks more specifically about EarthDNA, a nonprofit startup she co-founded to serve as a platform for climate advocacy and action. EarthDNA aims to curate petabytes of data and presents it in eye-catching visualizations structured around the four major subsystems of our home planet—oceans, land, air, and near space. But it won’t just present the facts; it also seeks to steer users toward actions and activities that will make a difference. One of the chief goals for the platform is to provide personalized information that is relevant to the user’s specific interests and geographic location because, as Prof. Newman explains, we all care most about what’s happening in our own backyards or in the places that are important to us.     Relevant Resources:MIT OpenCourseWareThe OCW Educator PortalEarthDNA on the WebProfessor Newman’s climate resources on OCWProfessor Newman’s aerospace engineering course on OCWProfessor Newman at MIT’s Institute for Data, Systems, and SocietyMusic 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.
