This is a learning module that uses data to investigate the ways in which attitudes about inequality and its causes and solutions differ between social classes.

D-Lab World Prosthetics is a collaboration between the Massachusetts Institute of Technology and the Jaipur Foot Organization to improve the design, manufacture, and distribution of rehabilitation devices in the developing world. The course welcomes individuals interested in physical rehabilitation to work on multidisciplinary teams of students with bioengineering, mechanical engineering, material science, and medical or pre-medical backgrounds. Students will learn about the basics of human walking, different types of gait disabilities, as well as the technologies that seek to address those disabilities. Patient perspectives and current research areas are presented. Lecture topics focus on lower-limb disabilities, including polio and above-knee and below-knee amputation, and will cover both developed and developing world techniques for overcoming these disabilities. Students form teams to design and prototype low-cost orthotic and prosthetic devices, and present their work at the end of the course.

In this lesson, from the World Affairs Council of Seattle - Global Classroom Program, students learn about United Nations Sustainable Development Goal #1: No Poverty. They will watch a series of short videos that will provide an introduction to the SDGs and the no poverty goal. This specific lesson has students explore the connection between environmental issues (one of the themes of this module series) and poverty.Students will engage in small and large group activities that require them to analyze secondary sources and participate in collaborative discussions about the impact of environmental challenges, such as climate change, on poverty levels in different contexts. These learning activities include completing a graphic organizer, reflecting on the conclusions of their peers in a gallery walk, and researching efforts to alleviate poverty in a specific local, national, or global community. Finally, students will evaluate what is being done to address poverty and how they could take action individually and collectively to address the issue.

An interactive applet and associated web page that demonstrate the concept of triangle inequality. The applet shows a triangle where the vertices can be dragged to reshape the triangle It shows that no matter what you do, the longest side is always shorter than the sum of the other two. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

What is economics and why should you spend your time learning it? After all, there are other disciplines you could be studying, and other ways you could be spending your time. As the Bring it Home feature just mentioned, making choices is at the heart of what economists study, and your decision to take this course is as much an economic decision as anything else.

Economics is probably not what you think it is. It is not primarily about money or finance. It is not primarily about business. It is not mathematics. What is it then? It is both a subject area and a way of viewing the world.

As we live in the aftermath of the Financial Crisis of 2008, there are renewed questions about the nature of the economic system—capitalism—within which we live. What are its benefits and drawbacks? Why does it garner both so much opposition and support? What are its moral, economic, social and political implications? Is it even a "system"? How has capitalism played out in different historical moments and regions of the world? This class addresses the question "what is capitalism?" from a social scientific point of view, rather than a classical economic one.
