The immune system plays a fascinating and vital role in the human body, recognizing outside threats and protecting our bodies against disease. This introductory immunology courses will help you understand the interactions of the immune system, and the jargon scientists use to describe immune function.

This is the second of a two-part course. In the first part we learned about innate immunity and B cell function. This second part covers T cell function and coordination of the immune response.

This immunology course surveys the cells of the immune system and describes how they talk to each other, receive information from the rest of the body and coordinate your defenses.

By presenting complex concepts in innovative, easy-to-understand ways, this course provides a solid introduction to how our immune system keeps us healthy.  

This is the last of five modules to introduce concepts and current frontiers of atomic physics and to prepare you for cutting-edge research:

8.421.1x: Resonance

8.421.2x: Atomic structure and atoms in external field

8.421.3x: Atom-Light Interactions 1 -- Matrix elements and quantized field

8.421.4x: Atom-Light interactions 2 --  Line broadening and two-photon transitions

8.421.5x: Coherence

This fifth module, 8.421.5x, looks at a central theme of atomic physics - coherence. This includes coherence of single atoms for two-level systems and three-level systems, and coherence between atoms, which can result in superradiant behavior.

At MIT, the content of the five modules makes the first of a two-semester sequence (8.421 and 8.422) for graduate students interested in Atomic, Molecular, and Optical Physics. This sequence is required for Ph.D. students doing research in this field.

In these modules you will learn about the interaction of radiation with atoms: resonance; absorption, stimulated and spontaneous emission; methods of resonance, dressed atom formalism, masers and lasers, cavity quantum electrodynamics; structure of simple atoms, behavior in very strong fields; fundamental tests: time reversal, parity violations, Bell's inequalities; and experimental methods.

Completing the two-course sequence allows you to pursue advanced study and research in cold atoms, as well as specialized topics in condensed matter physics.

FAQ

Who can register for this course?

Unfortunately, learners from Iran, Cuba, Sudan and the Crimea region of Ukraine will not be able to register for this course at the present time. While edX has received a license from the U.S. Office of Foreign Assets Control (OFAC) to offer courses to learners from Iran and Sudan our license does not cover this course.

Separately, EdX has applied for a license to offer courses to learners in the Crimea region of Ukraine, but we are awaiting a determination from OFAC on that application. We are deeply sorry the U.S. government has determined that we have to block these learners, and we are working diligently to rectify this situation as soon as possible.

Capturing and analyzing data has changed how decisions are made and resources are allocated in businesses, journalism, government, and military and intelligence fields. Through better use of data, leaders are able to plan and enact strategies with greater clarity and confidence. Data drives increased organizational efficiency and a competitive advantage. Simply, analytics provide new insight and actionable intelligence.

In education, the use of data and analytics to improve learning is referred to as learning analytics. Analytics have not yet made the impact on education that they have made in other fields. That’s starting to change. Software companies, researchers, educators, and university leaders recognize the value of data in improving not only teaching and learning, but the entire education sector. In particular, learning analytics enables universities, schools, and corporate training departments to improve the quality of learning and overall competitiveness. Research communities such as the International Educational Data Mining Society (IEDMS) and the Society for Learning Analytics Research (SoLAR) are developing promising models for improving learner success through predictive analytics, machine learning, recommender systems (content and social), network analysis, tracking the development of concepts through social systems, discourse analysis, and intervention and support strategies. The era of data and analytics in learning is just beginning.

Data, Analytics, and Learning provides an introduction to learning analytics and how it is being deployed in various contexts in education, including to support automated intervention, to inform instructors, and to promote scientific discovery. Additionally, we will discuss tools and methods, what skills data scientists need in education, and how to protect student privacy and other rights. The course will provide a broad overview of the field, suitable for a broad audience. Learners will explore the logic of analytics, the basics of finding, cleaning, and using educational data, predictive models, text analysis, and activity graphs and social networks. We will discuss use of analytics in data domains such as log files and text data.  Tableau Software is partnering with University of Texas Arlington to provide analytics software to course participants as well as technical support and guest lectures. Additional software will be introduced and discussed throughout the course.

How this course works:

This course will experiment with multiple learning pathways. It has been structured to allow learners to take various pathways through learning content - either in the existing edX format or in a social competency-based and self-directed format. Learners will have access to pathways that support both beginners, and more advanced students, with pointers to additional advanced resources. In addition to interactions within the edX platform, learners will be encouraged to engage in distributed conversations on social media such as blogs and Twitter.

We have all played and enjoyed games, but how do people actually design them? How do you describe a game? What are the basic elements? How do designers create an experience for the player? What about prototyping and iterating?

This course explores these questions and others through six content units over seven weeks. Participants will be introduced to game design and game design concepts, emphasizing the basic tools of game design: paper and digital prototyping, design iteration, and user testing. The audience for this course includes current and aspiring game designers and those interested in delving deeply into the game creation process.

For the course project, participants will create either a digital game or a board game. This course leverages Gameblox, a game editor that uses a block based programming language to allow anyone to create games. 

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 is the second mini-course in a four-course sequence.

• Mini-Course 1: History and Politics of U.S. Education
• Mini-Course 2: Teacher Policies
• Mini-Course 3: Accountability and National Standards
• Mini-Course 4: School Choice

Have you always wanted to write a novel? Have you started a novel only to run out of steam halfway through? Led by international best-selling authors and professors from The University of British Columbia’s world-renowned Creative Writing MFA program, this is part of a series of courses designed to take your novel from concept to completion.

Outlining is a crucial step in the novel writing process, one that fuels creativity and prepares the writer to stay on track and avoid common pitfalls. Through hands-on weekly exercises with a focus on craft and process, as well as insights from the real-world practices of accomplished authors, this course explores the core elements of fiction writing necessary to build an outline. You will learn the fundamentals of character development, world-building and the basics of storytelling architecture. You'll work intensively on your own creative project and hone your outline through feedback and discussion with fellow writers.

In the tradition of the UBC MFA program, this course draws on the work habits of established authors to help writers move quickly toward creating a blueprint for a successful draft. Whether you’re seeking literary fame or working on a project to share with family and friends, this course offers the tools and skills necessary to plan a novel others will be excited to read.

The course is recommended for professional and aspiring writers, writing groups, participants in NaNoWriMo, teachers and anyone who has ever dreamed of writing a novel.

When you’re designing and developing new software, it’s easy to get laser-focused on getting it functional and into the market or deployed as soon as possible. Thus, many engineering teams develop software that supports their native language first, postponing support for other languages until “later,” when they think they will have the bandwidth. In other words, they don’t plan ahead. The problem with this approach, which experienced developers have found out the hard way, is that it sacrifices budget, time, and opportunity.

Redesigning and rebuilding a different edition of your software for each and every language or market can be a colossal effort. As this computer science course will demonstrate, planning ahead is far more efficient, and the marginal cost of supporting multiple languages from the get go is less than you may think. Harnessing international functionality in operating systems and programming languages makes writing code that works for multiple languages and markets much simpler than retrofitting existing code.

The instructors for this course include programmers who have worked on globalization and localization of some of the world’s most successful software. They’ve experienced the good, the bad, and the ugly of creating world-ready software, and they’re here to ensure your software’s user experience works consistently, regardless of where users are from or what languages they speak.

This course has three parts: the business case, world-ready design, and world-ready development. While students can complete parts one and two without programming knowledge, part three requires programming experience.

Tokyo emerged out of the ruins of war to become a large city of 10 million people in only a quarter of a century. During this process of change, the capital of a military empire that once invaded East Asia experienced occupation by the U.S. armed forces, hosted the Olympic Games, and transformed into a consumer hub where young people could enjoy economic “wealth.” It is important to know that this process was recorded in countless photographs, documentary films, TV programs, and so on. We will retrieve many of these archived pictures and videos and analyze what happened in postwar Tokyo from different perspectives. In Part 1, you will look at the changes that occurred in postwar Tokyo over a quarter of a century from four different perspectives: 1) occupation and Americanism; 2) imperial gaze and royal wedding; 3) The Olympic city; and 4) economic-cultural clash in Shinjuku. This examination of urban history will provide you with the insights necessary when considering changes in other large cities in Asia, such as Seoul, Beijing, and Bangkok, at the end of the twentieth century.

8.EFTx is an online version of MIT's graduate Effective Field Theory course. The course follows the MIT on-campus class 8.851 as it was given by Professor Iain Stewart in the Fall of 2013, and includes his video lectures, resource material on various effective theories, and a series of problems to facilitate learning the material. Anyone can register for the online version of the course. When the course is being taught on campus, students at MIT or Harvard may also register for 8.851 for course credit.

Effective field theory (EFT) provides a fundamental framework to describe physical systems with quantum field theory. In this course you will learn both how to construct EFTs and how to apply them in a variety of situations. We will cover the majority of the common tools that are used by different effective field theories. In particular: identifying degrees of freedom and symmetries, formulating power counting expansions (both dimensional and non-dimensional), field redefinitions, bottom-up and top-down effective theories, fine-tuned effective theories, matching and Wilson coefficients, reparameterization invariance, and various examples of advanced renormalization group techniques. Examples of effective theories we will cover are the Standard Model as an effective field theory, integrating out the massive W, Z, Higgs, and top, chiral perturbation theory, non-relativistic effective field theories including those with a large scattering length, static sources and Heavy Quark Effective Theory (HQET), and a theory for collider physics, the Soft-Collinear Effective Theory (SCET).

Course Flow

Since this is an advanced graduate physics course, you will find that self-motivation and interaction with others is essential to learning the material. The purpose of the online course is to set you up with a foundation, to teach you to speak the language of EFT, and to connect you with other students and researchers that are interested in learning or broadening their exposure to this subject. Each week you will complete automatically graded homework problems to test your understanding and to help you master the material. You are expected to discuss the homework with other people in the class, but your online responses must be done individually. To facilitate these interactions there will be a forum for student-to-student discussions, with threads to cover different topics, and moderators with experience in this field. Student learning and discussions will also be prompted by questions posed after each lecture topic.

There will be no tests or final exam, but at the end of the course each student will give a 30-minute presentation on an EFT topic of their choosing. The subject of effective field theory is rich and diverse, and far broader than we will be able to cover in a single course. The presentations will create an opportunity for you to learn about additional subjects beyond those in lecture from your fellow students. To facilitate this learning opportunity, each student will be required to watch and grade five presentations from among their fellow students.

Since this is a graduate course, we anticipate that learning the subject and having the 8.EFTx materials available as an online resource will be more valuable to most of you than obtaining a grade. Therefore anyone who registers for the course will be able to retain access to the course materials after the course has ended. Note that when the course is archival mode that the problems can be attempted and checked in the same manner as when the course was running.

This course evaluates the medieval history of Toledo from the reign of King Alfonso “The Wise” (1252-1284) until the creation of the blood purity statutes in the 1450s.

This local history will concentrate on the relations of Jews, Old Christians, and converts to Christianity (conversos). We will study King Alfonso X’s efforts to characterize himself as the “king of three religions” via his legal codices, the creation of the Cantigas de Santa María, and his intellectual endeavor known as the Toledo School of Translators.

We evaluate the robust Jewish and converso noble families of the city and appreciate their intellectual, religious, and economic contributions to Castilian life. We will bear witness to the rise of anti-Jewish blood purity statutes, the creation of the Inquisition, and the expulsion of the Jews. We will virtually-tour the Cathedral of Toledo, El Transito Synagogue, Santa Maria la Blanca Synagogue, and several of its neighborhoods.

We also will study and transcribe manuscripts from the municipal, cathedral, and national historic nobility archives to make new scholarly breakthroughs.

No knowledge of Spanish is needed to participate in the course or in our transcription efforts.

Do you have a personal improvement goal that has proven resistant to your sincerest intentions, smartest plans, and best efforts? If so, then this course is for you. Last spring, we kicked off a world-wide experiment to see if Kegan and Lahey’s ground-breaking, award-winning approach (the Immunity to Change process) could be deployed online to help tens of thousands of people make lasting changes at work or in their private lives. The experiment was largely a success! Many participants succeeded at making important changes in their lives. Here’s what our students have to say:

• “When I first started, I was a bit skeptical on how I would actually change. Looking back at myself 14 weeks ago and comparing it with how I am now is incredible! I couldn't be happier that I decided to take this course and learn a new approach to change. My life is so much better because of it.”
• “Someone asked me recently if I felt like I'd just wasted 14 whole weeks on self-inquiry. I can honestly say no - I feel like I wasted 30 years sleepwalking!  An incredible experience. Bob and Lisa have created a truly wondrous process, and the staff and fellow students have built a rich and supportive learning environment.” 
• “I appreciated the opportunity to feel like I was a part of a bigger community striving to grow and improve. This made me want to constantly push myself because I believed in the power behind the material and in the power of being part of a community working toward similar goals.”
• “This has been an amazing course and I have made long lasting changes that I didn't even dream about when I began this course. There is no way to express my deepest thank you for that . . . my life is changed.”

This fall, we invite you to join us in a continuation of this experimental personal development course. Via demonstrations, exercises, readings, personal experiments, and novel interactive tools, this course will teach you new psychological theory about personal change, but—more than this—it will engage you in applying that theory to yourself from the first class to the last.

In 2011 Oprah Winfrey listed the Top Ten Things You Should Do to Start the New Year Right. Number One on the list was, “Try the Immunity-to-Change approach.” Come, join us!

This course runs from Tuesday, September 16 to Monday, December 15, 2014. It begins on September 16 with a one-week orientation. The orientation is designed to introduce you to the culture of the community we will form together and the technology we will use. Some of you may not need the full week to complete the orientation. The substance of the course begins a week later, on September 23.
