AP United States History

Advanced Placement United States History (also known as AP U.S. History or APUSH) is a course and examination offered by College Board as part of the Advanced Placement Program.

Curriculum

The AP U.S. History course is designed to provide the same level of content and instruction that students would face in a freshman-level college survey class. AP U.S. History classes generally use a college-level textbook as the foundation for the course.

Textbooks

Commonly used textbooks that meet the curriculum requirements include:

Criticism

American conservatives have criticised the curriculum for downplaying American exceptionalism and failing to foster patriotism. In 2014, there were protests against it in the Jefferson County Public Schools district in Colorado. In 2015, a bill to replace the curriculum was passed by the Oklahoma House of Representatives’ Education Committee, but later withdrawn.

Review

A review is an evaluation of a publication, service, or company such as a movie (a movie review), video game (video game review), musical composition (music review of a composition or recording), book (book review); a piece of hardware like a car, home appliance, or computer; or an event or performance, such as a live music concert, play, musical theater show, dance show, or art exhibition. In addition to a critical evaluation, the review's author may assign the work a rating to indicate its relative merit. More loosely, an author may review current events, trends, or items in the news. A compilation of reviews may itself be called a review. The New York Review of Books, for instance, is a collection of essays on literature, culture, and current affairs. National Review, founded by William F. Buckley, Jr., is an influential conservative magazine, and Monthly Review is a long-running socialist periodical.

In academia

A peer review is the process by which scholars or scientists assess the work of their colleagues that has been submitted for publication in the scientific or scholarly literature.

History of the United States

The date of the start of the history of the United States is a subject of constant debate among historians. Older textbooks start with the arrival of Christopher Columbus in 1492 and emphasize the European background, or they start around 1600 and emphasize the American frontier. In recent decades American schools and universities typically have shifted back in time to include more on the colonial period and much more on the prehistory of the Native peoples.

Indigenous people lived in what is now the United States for thousands of years before European colonists began to arrive, mostly from England, after 1600. The Spanish had small settlements in Florida and the Southwest, and the French along the Mississippi River and the Gulf Coast. By the 1770s, thirteen British colonies contained two and a half million people along the Atlantic coast east of the Appalachian Mountains.

In the 1760s the British government imposed a series of new taxes while rejecting the American argument that any new taxes had to be approved by the people (see Stamp Act 1765). Tax resistance, especially the Boston Tea Party (1774), led to punitive laws (the Intolerable Acts) by Parliament designed to end self-government in Massachusetts. American Patriots (as they called themselves) adhered to a political ideology called republicanism that emphasized civic duty, virtue, and opposition to corruption, fancy luxuries and aristocracy.

Extended periodic table

An extended periodic table theorizes about elements beyond element 118 (beyond period 7, or row 7). Currently seven periods in the periodic table of chemical elements are known and proven, culminating with atomic number 118.

If further elements with higher atomic numbers than this are discovered, they will be placed in additional periods, laid out (as with the existing periods) to illustrate periodically recurring trends in the properties of the elements concerned. Any additional periods are expected to contain a larger number of elements than the seventh period, as they are calculated to have an additional so-called g-block, containing at least 18 elements with partially filled g-orbitals in each period.

An eight-period table containing this block was suggested by Glenn T. Seaborg in 1969.IUPAC defines an element to exist if its lifetime is longer than 10⁻¹⁴ seconds, which is the time it takes for the nucleus to form an electronic cloud. No elements in this region have been synthesized or discovered in nature. The first element of the g-block may have atomic number 121, and thus would have the systematic name unbiunium. Elements in this region are likely to be highly unstable with respect to radioactive decay, and have extremely short half lives, although element 126 is hypothesized to be within an island of stability that is resistant to fission but not to alpha decay. It is not clear how many elements beyond the expected island of stability are physically possible, whether period 8 is complete, or if there is a period 9.
