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.
This is the fourth 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
HarvardX requires individuals who enroll in its courses on edX to abide by the terms of the edX honor code. HarvardX will take appropriate corrective action in response to violations of the edX honor code, which may include dismissal from the HarvardX course; revocation of any certificates received for the HarvardX course; or other remedies as circumstances warrant. No refunds will be issued in the case of corrective action for such violations. Enrollees who are taking HarvardX courses as part of another program will also be governed by the academic policies of those programs.
HarvardX pursues the science of learning. By registering as an online learner in an HX course, you will also participate in research about learning. Read our research statement to learn more.
Harvard University and HarvardX are committed to maintaining a safe and healthy educational and work environment in which no member of the community is excluded from participation in, denied the benefits of, or subjected to discrimination or harassment in our program. All members of the HarvardX community are expected to abide by Harvard policies on nondiscrimination, including sexual harassment, and the edX Terms of Service.

Protein is found in virtually every part of your body. At least 10,000 different proteins make you what you are and keep you that way.
In this biology course you will learn how proteins drive almost all living processes.
Proteins manufactured by cells perform a broad range of essential functions — the molecular workforce of living organisms.
You will learn how proteins are the cellular manifestation of genetic information. They are assembled into a polymeric structure from monomers derived in part from components in our diet. Proteins catalyze metabolic reactions, replicate DNA, respond to stimuli, provide movement, and much more. Using video lectures, articles, case studies, and molecular models, we will explore how proteins are constructed, how they fold into 3-dimensional shapes, the kinds of bonds that hold these folded structures together, and the immense range of roles that proteins assume ‑ from structural proteins found in muscle to catalysts for cellular chemical reactions.
Purification and characterization are essential to understand protein structure and function, and we will identify a variety of methods to uncover how these tiny machines drive almost all living processes.

This is the second of five modules to introduce concepts and current frontiers of atomic physics and to prepare you for cutting-edge research:
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
The second module, 8.421.2x, describes atomic structure, including electronic levels, fine structure, hyperfine structure and Lamb shift. You will then learn about how electric and magnetic fields shift atomic levels. The discussion of time-dependent electric fields prepares you for the interactions of atoms with light and for the dressed atom picture.
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.

Conoce la obra inspiradora de los principales pintores europeos desde 1400 hasta 1800 aproximadamente, y descubre los problemas que encuentran su expresión en el arte de la pintura. En este amplio marco temporal se incluyen artistas de la importancia de Leonardo da Vinci, Caravaggio, Velázquez, Rembrandt, Vermeer o Goya.
Los pintores durante este periodo estaban preocupados por ideas tales como la búsqueda de la belleza, los placeres y dolores asociados al amor, la demostración de poder y estatus, o la relación de hombres y mujeres con la divinidad y la naturaleza. En las pinturas del período cubierto en este curso se encuentran rastros de la aparición de la mentalidad moderna, así como información sobre cuestiones tales como los roles respectivos de los hombres y las mujeres en el mundo.
Este curso se centrará en imágenes de pinturas de los artistas que figuran en el programa del curso. Las discusiones que tendrán lugar en el "Foro del curso" nos permitirán abordar una gama más amplia de cuestiones.

8.421.4x: Atom-Light interactions 2 -- Line broadening and two-photon transitions
The first module, 8.421.1x, introduces resonance as an overarching theme of the course. You will deepen your understanding of the physics of resonance by examining systems using both classical and quantum techniques. Of special importance is the precession of a magnetic moments in time-dependent magnetic fields.

Organic electronic devices are quickly making their way into the commercial world, with innovative thin mobile devices, high-resolution displays, and photovoltaic cells. The future holds even greater potential for this technology, with an entirely new generation of ultralow-cost, lightweight and even flexible electronic devices, which will perform functions traditionally accomplished with much more expensive components based on conventional semiconductor materials, such as silicon.
Learn more about this highly promising technology, which is based on small molecules and polymers, and how these materials can be implemented successfully in established (e.g., organic light-emitting devices (OLEDs), organic photovoltaic (OPV) devices) and emerging (e.g., thermoelectric (TE) generators) organic electronic modules.
In this course you will gain the ability to tie molecular transport phenomena with macroscopic device response such that you will be well-prepared to analyze, troubleshoot, and design the next generation of organic electronic materials and devices.
This course has short lectures with quizzes, homework, and exams.
