All of us carry explicit or implicit theories of learning. They manifest themselves in the ways we learn, the ways we teach, and the ways we think about leadership and learning.

In Leaders of Learning, you will identify and develop your personal theory of learning, and explore how it fits into the shifting landscape of learning. This isn’t just about schools, it’s about the broader and bigger world of learning.

The education sector is undergoing great transformation, and in the coming decades will continue to change. How we learn, what we learn, where we learn, and why we learn; all these questions will be reexamined. In Leaders of Learning we will explore learning, leadership, organizational structure, and physical design.

When you're sick, you may wonder, "Why me?" But the real question should be, "Why am I not sick all the time?" You might even ask, "Why does my body respond with a fever, and is it really a good idea to lower it?" This course explores immunology, how the body defends itself from constant assault by parasites and pathogens. This course will present the fundamentals of both innate and adaptive immunity, emphasizing functional interactions among cells and organs. We will cover signaling, pathogen recognition and the division of labor among myeloid, lymphoid and supporting cells. The subject matter will also supply health professionals and biomedical researchers with the basic vocabulary and concepts necessary to understand both clinical press releases and primary literature. The course materials also provide support to other immunology instructors by presenting difficult concepts in creative ways using analogies and models.

The last century ushered in significant progress. Philosophers, scientists, artists, and poets overthrew our understanding of the physical world, of human behavior, of thought and its limits, and of art, creativity, and beauty. Scientific progress improved the way we lived across the world. Yet the last century also brought increased levels of war, tyranny, and genocide. Man pushed boundaries of good and evil, right and wrong, justice and injustice – and people lost faith in values. Now, thinkers and leaders are reconstructing theories of value and creating institutions to embody them. Join this thought-provoking, broad-sweeping course as it draws intriguing connections between philosophy, art, literature, and history, illuminating our world and our place in it.

Water is essential for life on Earth and of crucial importance for society. Water also plays a major role in affecting climate. Its natural cycle, from ocean to atmosphere by evaporation, then by precipitation back to land returning via rivers and aquifers to the oceans, has a decisive impact on regional and global climate patterns.

For students of engineering, climate science and environmental studies, this course offers a first introduction to the physics of water systems and their role in climate. In addition, we show you the state-of-the-art engineering interventions that can be applied to water systems. These can improve coastal safety and increase the availability of water supplies worldwide.

The course welcomes students from all over the globe, so we actively encourage discussion of water and climate issues you may experience in your location, now and in the coming decades.

After taking this course, you will be able to:

• Understand the different processes at play in the global water cycle.
• Identify and describe the flows of water and sand in different riverine, coastal and ocean systems.
• Identify mechanisms of climate change and explain the interplay between climate change, sea level, clouds, rainfall and future weather.
• Explain why, when and which engineering interventions are needed in rivers, coastal and urban environments.
• Explain why water for food and water for cities are the main challenges in water management and propose solutions.
• Explain and confront the challenges in better understanding and adapting to the impact of climate change on water over the coming 50 years.

The course consists of knowledge clips, movies, exercises, and exam assignments. There are opportunities to discuss course materials with your fellow students and the Course Team through our online forum. We also provide interactive feedback video sessions in which the lecturers discuss issues raised by students.

Delft University of Technology (TU Delft) has a unique reputation when it comes to water and climate, with faculty experts in the fields of climate research, water management and hydraulic engineering.

Globalization is a fascinating spectacle that can be understood as global systems of competition and connectivity. These man-made systems provide transport, communication, governance, and entertainment on a global scale. International crime networks are outgrowths of the same systems. Topics include national identity, language diversity, the global labor market, popular culture, sports and climate change.

However, an increase in integration has not brought increased equality. Globalization creates winners and losers among countries and global corporations, making competition the beating heart of the globalization process.

The globalization process exemplifies connectivity. Globalization is unimaginable without the unprecedented electronic networks that project dominant cultural products into every society on earth.

Learn how to identify and analyze global systems and better understand how the world works.

Behavioral medicine is the science of changing our behavior, so we as individuals can stay healthy and happy as long as we can. In this course on Behavioral Medicine, you will learn about basic behavioral medicine concepts and explore how they can be applied to help people who need to change specific lifestyle behaviors to attain better health. Working with virtual patient interactions will give you a chance to test behavioral medicine interventions. You will also learn self¬-help tools based on behavioral medicine, for whatever you need to change in your own life. In this updated version of the course, you will also explore innovations in how to deliver the tools of behavioral medicine to patients in primary care and psychiatry, and what kind of content digital tools might need to include.

To help people who need to improve their health by changing their behaviors, you will learn about Motivational Interviewing (MI), a counseling style that stimulates behavior change. You will have an opportunity to test basic techniques in MI with a “virtual bartender” who has sleep problems that he is trying to solve by drinking alcohol. The following sections will focus on coping with stress, improving sleep, increasing physical activity and everyday behaviors like hand washing, safer sex and minimizing risky alcohol use.

To complete this course, you will need to spend a total of about 30-40 hours. This time covers course videos, follow-up questions to help you remember what you have learned, course reading (mostly open access scientific articles) and homework tasks. Part of the work is for you to do on your own, and part will be together with other participants in the course community.

This course is offered in collaboration with EIT Health.

This course, the first installment of the multi-part Poetry in America series, covers American poetry in cultural context through the year 1700. The course begins with Puritan poets--some orthodox, some rebel spirits--who wrote and lived in early New England. Focusing on Anne Bradstreet, Edward Taylor, and Michael Wigglesworth, among others, we explore the interplay between mortal and immortal, Europe and wilderness, solitude and sociality in English North America.

Led by Harvard Professor Elisa New, Poetry in America surveys nearly 400 years of American poetry. Through video lectures, archival images and texts, expeditions to historic sites, interpretive seminars with large and small groups, interviews with poets and scholars, and conversations about poems with distinguished Americans, Poetry in America embarks on a journey through the literature of a nation. Distinguished guests, including President Bill Clinton, Elena Kagan, Henry Louis Gates, Eve Ensler, John McCain, Andrea Mitchell, Michael Pollan, Drew Faust, Tony Kushner, and Nas, among others, bring fresh perspectives to the study of American Poetry.

All around us, engineers are creating materials whose properties are exactly tailored to their purpose. This course is the first of three in a series of mechanics courses from the Department of Materials Science and Engineering at MIT. Taken together, these courses provide similar content to the MIT subject 3.032: Mechanical Behavior of Materials.

The 3.032x series provides an introduction to the mechanical behavior of materials, from both the continuum and atomistic points of view. At the continuum level, we learn how forces and displacements translate into stress and strain distributions within the material. At the atomistic level, we learn the mechanisms that control the mechanical properties of materials. Examples are drawn from metals, ceramics, glasses, polymers, biomaterials, composites and cellular materials.

Part 1 covers stress-strain behavior, topics in linear elasticity and the atomic basis for linear elasticity, and composite materials.

Part 2 ccovers stress transformations, beam bending, column buckling, and cellular materials.

Part 3 covers viscoelasticity (behavior intermediate to that of an elastic solid and that of a viscous fluid), plasticity (permanent deformation), creep in crystalline materials (time dependent behavior), brittle fracture (rapid crack propagation) and fatigue (failure due to repeated loading of a material).
