MTLE Social Studies (5-12) cheat sheet

Sourcing heuristic: before using a document, identify author, date, audience, purpose, and occasion - each answer narrows what the source can support as evidence.

Primary source = created at the time by a participant or witness; secondary source = later interpretation such as a textbook or monograph. Neither category is automatically more reliable.

Corroboration rule: independent sources that agree raise confidence; when they conflict, the historian must explain the discrepancy (different vantage point, audience, or time) rather than split the difference.

Contextualization: interpret a source within its own era's institutions, vocabulary, and assumptions; applying present-day standards is a separate analytic question, not a substitute for contextual reading.

Bias is not disqualifying. A one-sided source is strong evidence of its author's viewpoint and can still supply factual details that are checked against other sources.

C3 inquiry arc: (1) develop questions, (2) apply disciplinary concepts, (3) evaluate sources and evidence, (4) communicate conclusions through evidence-based claims.

Causation: distinguish long-term causes, immediate triggers, and underlying conditions; correlation alone does not establish a causal relationship.

Continuity and change: define the period and criteria first, because a change affecting one region, class, or group may not represent change for the nation as a whole.

Periodization is an argument. Choosing 1865–1877 versus 1865–1890s for Reconstruction reflects different claims about when federal commitment to civil rights ended.

Declaration of Independence 1776; Articles of Confederation in force 1781–1789 (no federal taxing power, no executive); Constitution written 1787, ratified 1788; Bill of Rights added 1791.

Marbury v. Madison (1803) established judicial review. McCulloch v. Maryland (1819) upheld implied federal powers via the necessary and proper clause and barred state taxation of federal instrumentalities.

Civil War 1861–1865. The Emancipation Proclamation (1863) applied only to rebelling states; the 13th (1865), 14th (1868), and 15th (1870) Amendments abolished slavery, defined citizenship and equal protection, and protected voting by race.

Reconstruction ended with the Compromise of 1877, followed by Jim Crow segregation, disfranchisement via poll taxes and literacy tests, and Plessy v. Ferguson (1896) approving "separate but equal."

Progressive Era amendments: 16th (federal income tax, 1913), 17th (direct election of senators, 1913), 18th (Prohibition, 1919), 19th (women's suffrage, 1920).

Great Depression: stock market crash 1929; New Deal (1933–1939) produced Social Security (1935), the SEC, and FDIC deposit insurance and expanded federal economic responsibility.

World War II: U.S. entry after Pearl Harbor, December 7, 1941; Executive Order 9066 authorized Japanese American internment; war ended 1945 with Hiroshima and Nagasaki.

Cold War containment: Truman Doctrine (1947), Marshall Plan (1948), NATO (1949); Korean War 1950–1953; Cuban Missile Crisis 1962; Vietnam escalation 1964–1973.

Civil rights: Brown v. Board of Education (1954) overturned Plessy; Montgomery Bus Boycott 1955–56; March on Washington 1963; Civil Rights Act 1964; Voting Rights Act 1965.

Neolithic Revolution c. 10,000 BCE: domestication of plants and animals produced food surpluses, enabling permanent settlements, occupational specialization, and social hierarchy.

River valley civilizations: Mesopotamia (Tigris–Euphrates), Egypt (Nile), Indus, and Shang China (Yellow River); large-scale irrigation required centralized authority and record keeping.

Classical empires - Persia, Greek city-states, Rome (republic to empire in 27 BCE), Han China, Maurya and Gupta India - shared roads, standardized taxation, law codes, and frontier defense.

Silk Roads and Indian Ocean networks moved goods along with Buddhism, Islam, papermaking, gunpowder, and the Black Death, which reached Europe in 1347.

Columbian Exchange after 1492: horses, wheat, sugar, and smallpox to the Americas; maize, potatoes, tobacco, and syphilis to Eurasia; disease devastated Indigenous populations.

Reformation (Luther's 95 Theses, 1517), Scientific Revolution (Copernicus, Galileo, Newton), and Enlightenment (Locke, Montesquieu, Rousseau) fed the Atlantic revolutions.

Industrial Revolution from c. 1750 in Britain: coal, steam power, textiles, and railroads drove urbanization, child labor, labor unions, and imperial expansion.

World War I 1914–1918 (militarism, alliances, imperialism, nationalism); Russian Revolution 1917; Treaty of Versailles 1919 imposed reparations and territorial losses on Germany.

World War II 1939–1945 included the Holocaust and atomic bombings of 1945; the United Nations was founded in 1945, followed by decolonization and the Cold War (1947–1991).

Five themes: location (absolute or relative), place (physical and human characteristics), human–environment interaction, movement, and region.

Absolute location uses latitude (degrees north or south of the equator) and longitude (degrees east or west of the prime meridian); one degree of latitude is roughly 69 miles.

Map projection trade-off: Mercator preserves shape and direction but exaggerates high-latitude area (Greenland); equal-area projections such as Peters and Mollweide preserve area but distort shape.

Climate controls: latitude, altitude, ocean currents, prevailing winds, distance from water, and mountain barriers producing rain shadows on leeward slopes.

Migration decision rule: push factors (conflict, famine, persecution, unemployment) repel; pull factors (jobs, safety, family, schooling) attract. Ravenstein observed that most migration is short-distance and economically motivated.

Demographic transition model: Stage 1 high birth and death rates; Stage 2 death rates fall and population grows fastest; Stage 3 birth rates fall; Stage 4 low rates; Stage 5 declining population.

Plate boundaries: divergent (Mid-Atlantic Ridge), convergent with subduction (Andes) or collision (Himalaya), and transform (San Andreas); the Ring of Fire encircles the Pacific.

Density measures: arithmetic density = people per total area; physiological density = people per unit of arable land; agricultural density = farmers per unit of farmland.

Land-use models: von Thünen's concentric rings around a market, Weber's least-cost location theory, and core–periphery models of uneven development.

Constitutional principles: popular sovereignty, limited government, federalism, separation of powers, checks and balances, and judicial review.

Power types: enumerated (Article I, Section 8), implied (necessary and proper clause), reserved (10th Amendment), and concurrent (shared by state and national governments).

Checks: presidential veto overridden by two-thirds of both houses; Senate confirms appointments and ratifies treaties by two-thirds; House impeaches and Senate convicts by two-thirds; courts exercise judicial review.

Amendment process (Article V): proposal by two-thirds of both houses or a national convention called by two-thirds of states; ratification by three-fourths of state legislatures or conventions.

Bill of Rights: 1st protects speech, religion, press, assembly, petition; 4th searches and seizures; 5th self-incrimination and due process; 6th counsel and speedy trial; 8th cruel and unusual punishment.

Landmark cases: Engel v. Vitale (1962, school prayer), Gideon v. Wainwright (1963, counsel), Miranda v. Arizona (1966), Tinker v. Des Moines (1969, student speech), Citizens United (2010).

Electoral structure: 538 electoral votes, 270 needed to win the presidency; 435 House seats reapportioned by census; 100 senators; House elections every two years.

Duties are legal obligations (obey laws, pay taxes, jury duty, selective service registration); responsibilities are voluntary (voting, volunteering, staying informed). Naturalization requires residency, English and civics testing, and an oath.

Federalists favored a strong national government and published The Federalist; Anti-Federalists demanded a bill of rights and stronger state authority.

Scarcity forces choice; opportunity cost is the value of the next-best alternative forgone, and it is the relevant cost in any decision.

Law of demand: price and quantity demanded move inversely. Law of supply: price and quantity supplied move directly. Equilibrium occurs where quantity demanded equals quantity supplied.

Elasticity = |% change in quantity ÷ % change in price|; demand is elastic above 1 and inelastic below 1. Necessities with few substitutes tend to be inelastic.

GDP = C + I + G + (X − M). Nominal GDP uses current prices; real GDP is adjusted for inflation and is the measure used for growth comparisons.

Unemployment types: frictional (job search), structural (skills mismatch), cyclical (recession), seasonal. The labor force counts the employed plus those actively seeking work.

Inflation is measured with the CPI; demand-pull inflation comes from excess spending, cost-push from rising input costs. Unanticipated inflation hurts lenders and fixed-income savers.

Federal Reserve tools: open market operations (primary), discount rate, reserve requirements, and interest on reserves. The dual mandate is price stability plus maximum employment.

Fiscal policy is government spending and taxation; expansionary policy raises spending or cuts taxes, contractionary does the reverse. Automatic stabilizers include unemployment insurance and progressive taxes.

Market structures: perfect competition, monopolistic competition, oligopoly, monopoly. Comparative advantage predicts gains from specialization and trade even for a less productive country.
