GACE Middle Grades Social Science (707) cheat sheet

Periodization rule: eras are defined by historians, not by nature; the same century can be grouped differently depending on whether the criterion is political, economic, or cultural change.

Chronology skill: BCE dates count backward (3000 BCE is earlier than 1000 BCE); there is no year 0, so centuries span e.g. 1801-1900 for the 19th century.

Primary vs. secondary source: a primary source is produced by a participant or witness at the time (diary, law code, artifact); a secondary source interprets evidence after the fact (textbook, monograph).

Sourcing heuristic: ask who made the document, when, for what audience, and for what purpose; purpose and audience shape what is included and omitted.

Corroboration rule: a claim is stronger when independent sources of different origin agree; agreement between sources sharing one origin is not independent confirmation.

Contextualization: interpret a document within its own political, economic, and social setting rather than judging it by present-day norms (presentism).

Cause vs. consequence: proximate causes are immediate triggers; underlying causes are long-term structural conditions; distinguish both from long-term effects.

Continuity and change: most historical periods show simultaneous persistence (e.g., agrarian economy) and transformation (e.g., urbanization), so avoid either/or framing.

Point of view and bias: bias is not simply falsehood; a source can be accurate yet selective, and the historian's task is to identify the perspective shaping selection.

Five themes framework: location (absolute/relative), place (human and physical characteristics), human-environment interaction, movement, and region.

Absolute location uses a coordinate grid (latitude measured from the equator 0-90 degrees N/S; longitude from the Prime Meridian 0-180 degrees E/W); relative location uses direction, distance, and landmarks.

Map scale: a large-scale map shows a small area in great detail; a small-scale map shows a large area with less detail; scale is a ratio, so 1:24,000 is larger scale than 1:1,000,000.

Projection trade-off: all flat maps distort shape, area, distance, or direction; Mercator preserves direction but exaggerates high-latitude area, equal-area projections preserve area but distort shape.

Climate controls: latitude, altitude, proximity to water, ocean currents, prevailing winds, and mountain barriers (rainshadow: wet windward slope, dry leeward slope).

Push-pull migration: push factors drive people from a place (conflict, unemployment, drought); pull factors attract them (jobs, safety, services); intervening obstacles reduce flow.

Demographic transition model: high birth and death rates (Stage 1), falling death rates (Stage 2), falling birth rates (Stage 3), low stable rates (Stage 4); population pyramids read the same stages.

Plate tectonics: divergent boundaries create rifts and seafloor spreading, convergent boundaries produce subduction, volcanoes, and trenches, transform boundaries produce strike-slip earthquakes.

Region types: formal regions share a measurable trait (language, climate), functional regions are organized around a node (a city's commuter zone), perceptual regions are mental maps held by people.

Separation of powers: legislative makes law, executive enforces law, judicial interprets law; each branch checks the others (veto, override, judicial review, appointment and confirmation, impeachment).

Federalism: delegated (enumerated) powers belong to the national government, reserved powers to the states under the Tenth Amendment, concurrent powers are shared (taxation, courts), and implied powers flow from the Necessary and Proper Clause.

Judicial review: established by Marbury v. Madison (1803); courts may void acts of the legislature or executive that conflict with the Constitution.

Incorporation doctrine: the Fourteenth Amendment Due Process Clause applies most Bill of Rights protections against state governments (Gitlow, 1925, began the process for speech).

First Amendment tests: speech restrictions must survive strict scrutiny unless the category is unprotected (incitement, true threats, obscenity, fighting words); symbolic speech is generally protected (Tinker).

Due process: procedural due process concerns fair procedures (notice, hearing); substantive due process concerns whether government may limit a fundamental right at all.

Civil liberties vs. civil rights: liberties are protections from government overreach; civil rights are guarantees of equal treatment and nondiscrimination (Equal Protection Clause).

Election rules: Electoral College votes equal a state's House seats plus two senators; winner-take-all applies in most states; reapportionment follows the census, redistricting follows, and gerrymandering is a redistricting abuse.

Types of government: in a democracy sovereignty rests with the people (direct or representative); in authoritarian systems (monarchy, dictatorship, theocracy, one-party) it does not.

Scarcity is the core problem: unlimited wants exceed limited resources, forcing choice; opportunity cost is the value of the next-best alternative forgone, not the sum of all alternatives.

Production possibilities frontier: points on the curve are efficient, inside are inefficient, outside are unattainable; the curve bows outward because of increasing opportunity cost.

Demand and supply: demand curve slopes down (price up, quantity demanded down); supply curve slopes up; equilibrium is where they intersect; a change in price moves along the curve, a change in a determinant shifts it.

Determinants of demand: income, tastes, price of substitutes and complements, expectations, number of buyers; determinants of supply: input costs, technology, taxes and subsidies, expectations, number of sellers.

Elasticity: demand is elastic when quantity responds strongly to price (many substitutes, luxury, large share of budget); inelastic when it responds weakly (necessities, few substitutes).

Market structures: perfect competition (many sellers, identical product), monopolistic competition (many sellers, differentiated product), oligopoly (few sellers), monopoly (one seller, high barriers).

GDP measures final goods and services produced within a country in a period; real GDP adjusts for inflation using a base year, nominal GDP does not; GDP excludes transfers, intermediate goods, and nonmarket output.

Business cycle: expansion, peak, contraction (recession, conventionally two consecutive quarters of falling real GDP), trough; unemployment types are frictional, structural, and cyclical.

Money and banking: the central bank uses open market operations, reserve requirements, and the discount rate; expansionary policy lowers rates to fight recession, contractionary policy raises them to fight inflation.

Comparative advantage: trade benefits both parties when each specializes in the good with the lower opportunity cost, even if one party has an absolute advantage in everything.

Inquiry arc sequence: develop questions, gather and evaluate sources, develop claims with evidence, communicate conclusions, and take informed action.

Compelling questions are disciplinary and debatable (e.g., should a city limit growth?); supporting questions are narrower and factual enough to answer with evidence.

Source evaluation criteria: authority (who created it), accuracy (verifiable against other sources), objectivity or purpose, currency (date), and coverage (scope).

Close reading of a document: identify claim, evidence, reasoning, and any unstated assumptions; separate what the author asserts from what the author proves.

Argument vs. opinion: an argument makes a claim supported by evidence and reasoning and acknowledges counterclaims; an opinion states a preference without evidentiary support.

Interpreting data: read the title, axes, units, and legend first; distinguish correlation from causation; note the base year and whether values are nominal or real.

Charts and graphs: line graphs show change over time, bar graphs compare categories, pie graphs show parts of a whole, and choropleth maps shade areas by value.

Citation and sourcing: cite the originator of an idea, not just the database; quote exactly and paraphrase in your own words with attribution to avoid plagiarism.

Disciplinary lens: historians weigh context and change over time, geographers weigh spatial pattern, economists weigh incentives and trade-offs, political scientists weigh power and institutions.
