How do robots climb stairs, traverse shifting sand and navigate through hilly and rocky terrain?

This course, part of the Robotics MicroMasters program, will teach you how to think about complex mobility challenges that arise when robots are deployed in unstructured human and natural environments.

You will learn  how to design and program the sequence of energetic interactions that must occur between sensors and mechanical actuators in order to ensure stable mobility. We will expose you to underlying and still actively developing concepts, while providing you with practical examples and projects. 

How do robots “see”, respond to and learn from their interactions with the world around them? This is the fascinating field of visual intelligence and machine learning. Visual intelligence allows a robot to “sense” and “recognize” the surrounding environment. It also enables a robot to “learn” from the memory of past experiences by extracting patterns in visual signals.

You will understand how Machine Learning extracts statistically meaningful patterns in data that support classification, regression and clustering. Then by studying Computer Vision and Machine Learning together you will be able to build recognition algorithms that can learn from data and adapt to new environments.

By the end of this course, part of the Robotics MicroMasters program, you will be able to program vision capabilities for a robot such as robot localization as well as object recognition using machine learning.

Projects in this course will utilize MATLAB and OpenCV and will include real examples of video stabilization, recognition of 3D objects, coding a classifier for objects, building a perceptron, and designing a convolutional neural network (CNN) using one of the standard CNN frameworks.

This course will cover the theory and the fundamentals of the emerging science of Sabermetrics. We will discuss the game of baseball, not through consensus or a fan’s conventional wisdom, but by searching for objective knowledge in baseball performance. These and other areas of sabermetrics will be analyzed and better understood with current and historical baseball data. 

The course also serves as applied introduction to the basics of data science, an emerging field of scholarship, that requires skills in computation, statistics, and communicating results of analyses. Using baseball data, the basics of statistical regression, the R Language, and SQL will be covered.

This course was successfully taught on the edX platform as a MOOC in 2014. This course has also been successfully taught at the Experimental College at Tufts University since 2004.  Many of its former students have gone on to careers writing about baseball and working in various MLB baseball operations and analytics departments.

This mini-course seeks to answer the following question: How did a school system, once the envy of the world, stumble so that the performance in math, science, and reading of U.S. students at age 15 fell below that of students in a majority of the world’s industrialized nations?

Exploring that question, we identify the personalities and historical forces—the progressives, racial desegregation, legalization and collective bargaining—that shaped and re-shaped U.S. school politics and policy. We visit the places where new ideas and practices were spawned, and we look at some of their unanticipated consequences.

In the three subsequent mini-courses, we seek answers to a second question: What are the best ways of lifting the performance of American schools to a higher level? To explore these questions, we look at ideas and proposals of those who want to save our schools—be it by reforming the teaching profession, holding schools accountable, or giving families more school choices. In interviews with reform proponents and independent experts, we capture the intensity of the current debate. In the end, we do not find any silver bullets that can magically lift schools to a new level of performance, but we do pinpoint the pluses and minuses of many new approaches. These three subsequent mini-courses will launch later in the fall and continue into 2016.

Each mini-course contains five to eight lectures, with each lecture containing approximately three videos. The mini-courses also include assigned readings, discussion forums, and assessment opportunities.

This is the first mini-course in a four-course sequence.

This mini-course looks in-depth at modern-day issues surrounding teacher policies in U.S. education.

The teacher is the most important person in our schools. How do we recruit and retain the very best teachers? What are our current methods for recruiting teachers? How well do we compensate them?  What are the effects of adjusting teacher salaries to be based on their performance in the classroom? When should teachers be given tenure? Do current policies encourage or discourage effective teachers from entering the profession?

Many questions come down to budgetary constraints. Should you hire more teachers so you have smaller classes? Should it be a priority to balance how much is spent between wealthy and poor districts?

Throughout this mini-course, we will be focused on using empirical evidence to answer these questions.

This mini-course contains six lectures, with most lectures divided into three videos. The mini-courses also include assigned readings, discussion forums, and assessments.

This mini-course focuses on the question of accountability in public schools.

Who is accountable for student outcomes? Should we blame the schools or hold the students themselves accountable? Who determines the standards for accountability – the federal government or the individual states?

The demand for accountability in U.S. education resulted in No Child Left Behind and has shaped the Common Core debate. Throughout this mini-course, we will trace the origins of the accountability movement, the increased role of the federal government, the design of accountability interventions, and the impact of accountability programs on student performance.

This mini-course focuses on alternatives to public schools in the United States.

There has been a rapid expansion of school choice in U.S. education. Charter schools now serve over five percent of the public school population, voucher programs have been introduced in many states, and digital education has captured the attention of educators across the country. What is the theoretical basis for these innovations? How effective are the early initiatives? How do parents decide what is best for their children? And how do all of these options affect the students who remain in traditional public schools?

With the help of several scholars and participants in these new ventures, we will discuss the ways in which these school choice initiatives are re-shaping U. S. education.

This mini-course contains five lectures, with most lectures divided into three videos. The mini-courses also includes assigned readings, discussion forums, and assessments.

During each week of this course, chefs reveal the secrets behind some of their most famous culinary creations — often right in their own restaurants. Inspired by such cooking mastery, the Harvard team will then explain the science behind the recipe.

Topics will include:

• How molecules influence flavor
• The role of heat in cooking
• Diffusion, revealed by the phenomenon of spherification, the culinary technique pioneered by Ferran Adrià.

You will also have the opportunity to become an experimental scientist in your very own laboratory — your kitchen. By following along with the engaging recipe of the week, taking precise measurements, and making skillful observations, you will learn to think like both a cook and a scientist. The lab is certainly one of the most unique components of this course — after all, in what other science course can you eat your experiments?

How do artists create visual effects? In order to create an artistic impression, artists select materials that allow image formation, and that lend color, emphasis, shape, and size to the object created.

A scientist might follow up by asking, why those materials?  What characteristics do they have that allow them to embody the artist’s intent? How durable are they? Will they maintain the same qualities, both physical and aesthetic, they had when the work left the studio?

Conservation science further notes that all materials deteriorate over time, and then asks a follow-up question: What physical interventions are possible to maintain, preserve and protect the work as the artist intended? Whatever is done to the art object, the result must be to make the work recognizable as the artist’s work or the result is a failure.  

That is a key goal of this course: to understand, from a chemical point of view, how conservation protocols and the material aspects of an art work allow a better appreciation of an artwork and its creation, as well as confidence that it is the artist’s work.

These are not new problems. According to Leonardo da Vinci, the study of art should include the following topics:

• A knowledge of materials
• The chemistry of colors
• The mathematics of composition
• The laws of perspective
• The illusions of chiaroscuro

As the briefest study of Leonardo's life shows, he was clearly ahead of his time in wanting to understand the reasons for a vast array of natural and artificial phenomena. Even so, a thorough understanding of those subjects listed above still escapes us today – but, progress has been made and that progress is at once the subject matter and the goal of this course.
